How NOT to Unseize a Stuck Engine! - Latest Auction Find!

welcome back behind me is my latest purchase it is a ji case company model La tractor I believe it's a 1949 just picked this up at a consignment auction no real Rhyme or Reason other than I saw it the other day it just looked big and cool so I went back and went ahead and bought it so it's pretty straight pretty original um I believe it's been repainted but it's got the original case gauges in it and if there's anyone out there that's interested there's the serial number 5329283 it's missing the battery cover and the toolbox that would have went over there but other than that it's very straight very original Wheels in nice shape the only play is in the Box itself all the kingpins and the tie rod ends and stuff they're tight rear wheels are in good shape there's no fluid in them tires are old have some cracking but front ones are pretty rough but they've sat flat kind of peeling off there and these are 18 inch front front rims so but the big problem with this thing is the engine seized uh headed at the auction couldn't spin it with the fan but was able to put it in gear and rock it several times and were able to get the fan blade to twitch but that's all I know since it's a consignment auction I don't know any history how long it sat or anything like that I'm guessing 10 to 20 years based on the color of the fuel and the fuel bowl and the smell in the fuel tank but to start off I'm gonna go ahead and get a borescope I'm gonna pull the plugs out and take a look down there see what it looks like hopefully nothing too crusty you can put some penetrating oil in there and let it soak for a few days so these tractors were built between 19 40 in 1953 this is a 403 cubic inch four-cylinder gasoline powered engine they are governed at only about 1100 RPM that plug looks good that looks really good actually kind of suspiciously good but at 1100 RPM they uh they make almost 60 horsepower so pretty impressive for what they are they're a big heavy machine 7 500 maybe 8 000 pounds I think so this one's got a couple wheel weights so it could be closer to the 8 000 pound number one looks really good too [Music] they're they're not uncommon they're a little more Uncommon where this one came from and uh Northwest Ohio this one's kind of tight but they were I think they were kind of more of a not necessarily A Prairie Tractor but more common out west where they were bigger fields well back in this era you would have seen a lot of like 40 horse tractors around here not 60. this would have been one of the biggest tractors in its day yeah so that's the cylinder we got an issue with got some rust on it doesn't look terrible but definitely some moisture in number three I think number three is the only one because this one's coming out easy as well thank you yeah number number four is a little dark but looks healthy so we're gonna go ahead and this is cylinder number one looks like it's got some moisture in there some condensation type moisture got a valve hanging down looks okay yeah I don't think we're stuck here this is cylinder number two similar deal we got some condensation going on some light rust down the cylinder walls uh maybe a little around the around the edges but oh no it looks pretty good this is back in number one yeah this looks this looks all right looks like we've got a dead wasp or something in there I think here's where trouble is this is number three yeah we've got some Rust there Pistons almost at uh top of the cylinder we got a little ways to go so that's good it's not stuck right at top dead center but yeah not the worst I've ever seen but we've definitely got some moisture in there so we'll go back to uh number four I'd say number four is the best looking one doesn't really look like any moisture in number four I'm gonna get some penetrating oil and whoa put some in each of those cylinders what I've got here is just some automatic transmission fluid and some acetone mixed together some people swear by it I've never used it for much but I've been trying it out lately and seems to work just gonna go ahead and put several pumps in each cylinder temporarily screw these plugs back in for now and we'll let this thing sit for a few days and allow this concoction to do its work hopefully we can come back in a couple days and rock it back and forth and it'll come loose and in case you were wondering what the top speed of one of these six two powered military trucks with about 11 000 pounds behind them is it's about 50 50 to the floor 58 miles an hour back here a couple days later let this soak gonna jack up the right rear wheel of this thing and rock it back and forth and see if we can get that engine loose I'm gonna put the transmission in fourth gear these have kind of a different style shifter so H pattern so the center and down should be fourth gear that's the highest gear now I've got you placed here so you can see the fan blades and I'm gonna rock the rear wheel back and forth and see if we can get the engine to turn let's twitching trying to get a little heat in there maybe help that stuff break loose [Music] I went ahead and took the binders loose and took it down off the Jack I'm gonna see if I can use the whole tractor to rock back and forth see if that'll give a little more Force onto it see if that'll get it loose well it did no good well I don't have a hand crank to stick through here I'm going to try to make something you can just drill a hole in this piece of pipe and stick a bolt through it once it's through the casting foreign [Music] oh yeah that engages both sides and go ahead put a pipe wrench on it foreign that's not really doing any better it's just making the fan jump about the same I'm gonna go ahead and see about rocking it back and forth with the trucks pull forward hit the brakes backwards hit the brakes well I guess I should have used a thicker pipe for that gotta get that out of there now all the rocking back and forth just seems to be skidding the tractor forwards on the trailer so I'm gonna let it soak for another day or two but first I filled up these cylinders and I'm just curious if they're draining down or if any of them are pooling up like they're you know if it's pooled up it's probably seized all the way around the Piston so I'm going to put borescope back in it and uh see what they look like this is number one not really coming into Focus well but for the amount of oil I put in there it looks like it's draining down man cylinder two cylinder two is full so that one's seized up and this is numbered three number three is the same way looks like it's holding fluid on top and number four looks like it's draining so number two and three are stuck so I'll go ahead and let this sit for a couple days and we'll check back let's spend another 24 hours and I put a bore scope back in cylinder two and three and cylinder two the oil has gone down in cylinder three it's still sitting on top of the piston but I need to use this trailer tomorrow so I get this thing off [Music] thank you foreign thank you [Applause] foreign like this tied together I'm going to go ahead and put it in gear and rock it with that tractor a little bit [Applause] thank you nothing sucks oh there you've seen we tried to drag it around pop the clutch a couple times but it's you know that fans just barely moving that that number three piston is still is still stuck so really don't want to end up taking it apart so I'm going to go ahead and give her a few more days or a week to to sit so this thing has been going on a week now with the cylinder soaking and number three is still holding fluid like a lot nothing's seeping past the Rings so I'm gonna see if we can force it a little bit I've got this what I I made it a couple years ago for testing compression but it's just a spark plug with a quarter inch pipe fitting welded on and I'm going to go ahead and put shop air to that number three cylinder and see if we can I don't expect it to break the engine loose but I'm hoping to take some of that oil and force it down past the piston and the Rings and just get it soaking a little better so I can get it freed up start he's going to take this and thread it in which it it's kind of surprising to me it seems like this cylinder the uh the valves are closed which I I expected them to be open and this somehow had gotten moisture in it externally but maybe this one the valves are closed in any condensation um just couldn't get aired out I'm not sure all right his bubbles coming somewhere but that sounds like head gasket bubbles to me I don't see any in here yet but foreign like it's bubbling up through the head so this thing might have a cracked head on it oh well that's better it's just leaking past an intake valve a little bit it's gurgling through the oil bath air cleaner man I thought we thought we were gonna have to put a head on this thing for a minute I think we might be all right another day later with air on it foreign [Music] got a little more solid piece to put in the front crank on this thing instead of a piece of pipe got a solid bar so maybe we can torque it a little with that oh I'm gonna give it a couple shocks to it foreign hanging on there like I said it's about 155 pounds about four foot out maybe you can do the math but get some Force well I'm back to the back to the tract or hitting for about a week and a half with penetrating oil in the cylinders still seems like it's stuck on cylinder number three tried to rock the wheel back and forth had pressure in the cylinder trying to push it down and I've had weight hanging on the crank and nothing seems to really be getting it loose but I think that's mainly because the Piston is almost the top dead center so I've got a hydraulic pump we're going to hook up to that piston and in that cylinder and see if we can raise that pressure up a little higher and break it Loose today now what I mean with that crank being at top dead center so the crank is offset so the connecting rod is connected over here but as the crank goes around when it's at top dead center or near top dead center there's really no leverage to push on that piston back and forth if it was middle of the stroke you would have all this leverage off the center line of your crankshaft so where it's at right now is like that and you just you know you don't have much leverage to push on that piston so I think the best bet is to put some pressure in the cylinder and push it downward with hydraulic fluid and I'm not going to put a ton of pressure in it as far as I can figure this engine would make about 140 PSI of cranking pressure at this elevation so I'm assuming safely some combustion pressure would be around 200 PSI I maybe even as much as 300 PSI under a hard load so I think the 200 250 psi range would be pretty safe bet but I really don't want to blow a head gasket out that's the whole point of going about it this way and not pulling it apart but if this doesn't work I'll have to pull the head off uh but we'll worry about that then now the reason I'm taking the hood off of this is because I really thought originally I could just wiggle it loose and wiggle it back and forth and I wasn't too worried about stuck valves or anything but since we're going to be putting a couple hundred PSI in that cylinder that's creating quite a bit of force and I don't want that Force to just blow by whatever else may be stuck so I've had worked on case engines before and both times that I was in them they had sticky valves that pen that bent push rods um the push rods in these engines I'm not sure on this specific tractor but the other ones I've worked on that were case are very soft and they Bend easily so I want to take the valve cover off and just tap on each valve and make sure everything's moving maybe spray a little penetrating oil up there just and once we have it going we can see if there's any oil getting up there making sure everything's working so we're gonna pull that off now this is a hunk of cast iron so two bolts and a little bit of struggle and we'll have it off there curiosity feet five inches from the pan to the top of the valve cover so not talking a little engine here the head the head is every bit of six inches tall about 30 inches in length it's a big engine [Music] [Music] foreign [Music] that should be a lot better I just wanted to get the majority of the loose stuff off so when I lift the valve cover off we don't have anything falling in something else to note though this exhaust manifold was something that I was looking at the auction as well and it's just it looks like it's in great shape um that's something that you don't see very often you're a lot of these old tractors they have holes in them or they're just pitted like crazy this one looks pretty nice and they're they're not a real simple piece you know uh they're I don't know if they make these new anymore so it's something to pay attention to when you're buying stuff like this you want as many original components as you can get that are in good shape that way you don't have to scrounge and buy used parts or fix things up that uh may be passed on [Music] well this is good that I pulled this apart so let's go to the other side of the engine maybe should have pulled this off a little sooner definitely got some corrosion on this valve definitely got some corrosion on this so those would be these would be our exhaust valves on number two and three um let me get some air and a shop back on this and sometimes this looks way worse than it is you can also see on the number one exhaust valve it's it's similar looking all right songs here's a look at the valve cover it's got some condensation in it uh rust from condensation but it's not as bad as I expected now what I'm starting to find in here is worse than I expected um it looks like these exhaust valves maybe have like a Thrust bearing or something on top that would so the valve would rotate those look to be in pretty rough shape you can see this one's like delaminated kind of coming apart they're all pretty Rusty the valves themselves at at first glance they don't seem too bad um but those keepers or I maybe you would call it a retaining washer this part that the keepers go in is pretty bad and it looks like on this number one exhaust valve the keepers which that tapered part down in there is actually the keepers and it looks like this has maybe rusted out and the spring has pushed it up top and then the whole washer is sitting against the rocker arm so I think we're gonna have minimally we'll see how it goes but we're minimally probably gonna have to put new uh Keepers and washers on the top of these valves but I just sprayed them up we're going to let them sit for a little bit and I'm going to kind of work them back and forth and try to make sure all the valves are are functioning all right that exhaust valve's free that's the main one I was worried about yeah so that's number three exhaust valve that was the main one number three intake number four intake that was a little sticky but number four exhaust got number two exhaust that one's kind of sticky that's good number two intake is good number one intake is good number one exhaust is good so now that I know all the valves are loose I said I had main concern was bending these push rods and they're long they're long push rods so long way to let that thing give out and they're not very big in diameter at all but I'm gonna go ahead I'm gonna hook this hydraulic pump up to it and we'll have a gauge on there and see if we can get this thing to move I'm going to pre-fill this cylinder as full as I can get it that way I don't have any extra air compressing in there it shouldn't take much he said it's at the top of the near the top of the stroke so here's the setup we got the adapters coming out of the cylinder to a quarter inch hydraulic line and that's going to this hand pump here with a gauge I'm going to just go ahead and pump it up to well we'll see what it takes but around 200 or so PSI and you'll be able to see if this lever starts moving then it's coming loose foreign the oil is leaking past the something on this and I'm assuming it's leaking past the intake valve because that's what the air was doing prior and I don't really want that to build up a whole lot so see about cracking this loose and uh letting it drain down foreign off for now and try to rock the tractor back and forth because I had it up to almost or maybe at 750 PSI and that's just pushing this thing it really I you know I don't believe the head gaskets are designed to pull that much when we take the hose off I'm going to put the push bar on and I'm going to rock it back and forth and see if we can get it jarred loose maybe that pushed something around there I just have a hard time believing this thing is stuck this bad you probably don't see many of these old mechanical floor jacks around anymore this one's a walker brand a walker roller car foreign why it was at the auction anymore not everything at the auction is junk but all the junk is at the auction this might not be junk but it's not great it's turning it's turning by golly there you go got you set up with a reference you should be able to watch it it's taking about 600 PSI to turn it that number three is on the downstroke down to 500 to turn it 400 to turn it curious if I can get it to turn by hand now and by hand I mean a three foot bar no it's still plenty stuck [Applause] [Music] now it seems to be to the point where the exhaust valve on this cylinder is trying to open and it's tight so I don't want to add any more pressure because that's not allowing it to open with all the pressure in there gonna see about pulling this thing either forwards or backwards and uh I would I'm hoping if I can push it backwards push it back up and get that oil through and I've got the hose still connected so all that oil in the cylinder should hopefully end up in that catch bucket I'm curious to see if there's any or if you're fighting a bearing or something that's a luxury you don't get I'm most I've been able to look in the side so number three right there in front don't look any different to number four it don't look sludgy in there either but yeah it's pretty cranks pretty much at the bottom of a stroke I guess we could pump four up and push it with four that's what I try doing number two and number one look good as well yeah so I'm just gonna take number four and pump it and it'll it's gonna work it backwards probably but it'll run it back up that's what you want to do yeah so right now number three is at the bottom of the stroke and number four is at the top of the stroke so I'm going to pull the push rods off of number four so the compression stays on that cylinder and it doesn't leak off and I'm going to push number four back down and that in case we'll push three back up and then hopefully I can work it back and forth between the hydraulic pump and the hand crank because pulling it it just doesn't have any leverage off the crank to move this and it's it's still stuck tight enough that it doesn't want to move oh it's gonna drain the oil back out of this cylinder so it doesn't make as big of a mess when it turns got everything primed up so you should see the fan turned in camera wise clockwise position well it seems like the oil is leaking plant past um cylinder number four is piston rings a lot easier than any of the others so might be a little pump fast enough to get it going but you have to do a lot more volume on that or a thicker fluid it's just running past the rings on cylinder number four this isn't going to work I'm kind of pondering on this thing now because we drug it down the road trying to go forwards and backwards and that won't turn it so it doesn't seem to matter and you know and that's put and leverage directly on the crankshaft fronts you know through the powertrain the crank on the front won't turn it the other cylinders won't hold enough pressure in the Rings to push it backwards and that's also with a reduced mechanical advantage because they're also at the top the only reason we were able to get that one pushed down was because we were pushing directly on the Piston not leveraging through the crankshaft so I think at this point unless you know some miracle by allowing the engine to sit for months would allow it to loosen up um the only other way to get some kind of a loosening effect in this engine is to heat that cylinder up so what I'm going to try to do is I'm going to push these this intake and this exhaust valve open and I'm going to try to run a torch in there and hopefully I can get enough air in there to keep that torch running and heat that cylinder up and by heating that cylinder up hopefully it's enough expansion to allow that to finish its rotation and get it rotating and freed up but other than that I I'm not sure you know maybe we could pull the oil pan and Jack a board and block up through there and push that piston back up with the rod but then at that point you you're just pushing all that force on the rod and not that what I'm doing already isn't stressful on the connecting rods but that's going to put a lot of force on it so I think heat is the only option I've got right now I got this propane torch that I can leave pretty low Flame [Music] oh no way it's staying lit now lost her Flame little Flame come out of there [Music] [Music] just like a chimney I've had this torch running in here for idle now 15 20 minutes at least it's getting some heat up on the head it's face down towards the Piston I don't really think it's getting the cylinder walls very warm but as long as there's some heat differential I'll give it a try see if anything spins here foreign guys come here come on guys all right well this thing was sitting overnight and uh came back here today I put some heat under that piston yesterday Heat on top of it put a bunch more PB Blaster in the cylinder and I kind of missed the moment I'm not gonna lie to you I just put that bar on there and it turned so let me see if I can get it to make a full Revolution and if that's the case hopefully today's the day that this thing runs again but let's not get ahead of ourselves let's see let's see if it'll turn complete 360. I'm not even sure if I need this bar on here so we can use this for index but it's still oh honey tight not locked up again dad I sprayed all the cylinders yesterday they should have plenty of lubrication but yeah so we're back about halfway up and about the best spot you could be the crank arm is over here pushing upward now I'm going to jack the rear tire up and see if rocking it will uh help us out a little bit foreign I did not bring the hydraulic pump with me that I was using yesterday because I really didn't think I needed it or if I did it wasn't going to do me any good but I could have used it right now so instead this is the setup got my Ford 3000 I've got a pressure gauge on it so I can monitor the pressure and just feather the Hydraulics and we're going to use the tractor hydraulics to push that piston back down foreign [Music] [Music] that worked really well and really smooth and I'm gonna see if I can work it back the other way I'm gonna want this to drain out though they don't want to put that dirty oil a chance of getting it back into the tractor thank you foreign back up so I'm just going to push it back down again and just going to kind of do this and work it back and forth I guess [Music] well I either broke something or it came free I think we made it over top dead center yeah I think we got it it's over top dead center and never find that thing you just had in your hand I've turned the crank around about five or six revolutions it's freed up it still has a little bit of a tough spot uh when that number two and three pistons when they come up so in the third cylinder where it was really stuck but I'm Gonna Leave the plugs out of it I'm gonna try to throw a battery in it I got 12 volt here this is a six volt tractor but I unhook the generator so there shouldn't be any issues there's no distributor on this thing it's all a Magneto so I'm gonna throw that battery I hope it's charged in this thing and see if we can wing it over with starter a few times see if it'll build oil pressure um just kind of get an idea loosen it up a little bit and uh if everything goes good we'll call this a success [Applause] [Applause] foreign [Applause] see a little bit of smoke coming from our starter so we don't want to overheat that in the rest of the oil a lot of those cylinders got a six volt battery in it now see if that makes any difference well if you're still watching I appreciate it so this video is getting awful long I'm gonna go ahead and end it about here I'll make a new video coming up next we'll do that about getting this thing running but for now we're going to call this a success by getting this engine unseized it was a lot more difficult than I expected but I don't believe we damaged anything so that is a plus but if you like content like this feel free to subscribe and leave a like and a comment tell me what you like what you don't like what you'd like to see in the future but I appreciate you all watching and I'll see you on the next one
