1960 Oliver OC46 Crawler - Will it Run and Drive after Sitting in a Barn for 13 Years?

howdy folks welcome back i thought we could try something a little bit different this is an oliver tc something crawler loader and the loader's missing obviously as far as i know it hasn't run for 13 years and it's been sitting in a barn that whole time they just pulled it out i guess this morning and we're going to try to get it running and driving now 13 years ago the engine was taken apart and the head gasket was replaced but now there's no cooling in it so he's worried that it might have it might have failed again just from sitting i don't know we're going to pop the drain plug out i think and see what we can figure out this is a three-cylinder gasoline hercules engine and it's been converted over to 12-volt so there's your little three three-pot distributor there it's got a delco alternator and the solenoid here for the starter the carburetor i'm not sure on he said he he actually built one of the jets for it but he's got a factory replacement for that so we're gonna get into that and then it only steers in one direction now these machines have what they call a spot turn which is some kind of a complicated differential steering system and it doesn't work on one side so if we get it running we got to figure that out anyway cute little machine undercarriage seems to be in pretty good shape look at the sprockets and the pins are i think pretty tight except for the master pin here but yeah looks good and it's been stored inside so i think we got a pretty good chance at it but i think first things first let's pop that drain plug out and see see if we've got any coolant in the oil so i'm not sure about that and check it out i actually brought my own luxury accommodations this time i'm sorry there's going to be some wind noise guys it's pretty windy out and i forgot to bring my external mic all right looks like it's a 3 8. i don't see any kind of a belly pan or skid pan on this which is interesting sure looks like oil to me yeah i don't see any water in that i mean it doesn't feel it doesn't feel watery so it's way over full on oil which is why i think he thought that the head gasket was bad i thought it was full of coolant but i don't think that's the case it may be full of fuel but let's see if we can get some signs of life out of it and if it's got spark i'll try to start it up and i'll go ahead and drain the oil and change it out real quick somehow i forgot to bring a battery so that's not very smart and i forgot to bring my jumper cables but i brought a battery charger so you know that'll help us a lot out here where there's no power gingerly take this positive cable off because there's still power there okay okay well we got something see the starter's got an open armature so i don't know yep all right well that thing's pretty pretty cruddy let me see if i can turn it over by hand all right i think the problem's not the brushes it's in this bar so if i go right here i got power there but if i go on the stud nothing so let's pop that guy off there and see what we can do oh it's loose i guess that's all it needed okay she's got compression blew the cap right off the exhaust see if we got any kind of sparkage here so we should have power there key on we do now if the points are working can you guys see that now if the points are working when i crank it we should see the light flicker and they do not so we better clean the points oh boy the inside of that cap's pretty rough pretty rough it's all standard delco ignition system on this guy yeah we're looking pretty pretty nasty on the points okay the points are clean just a little corrosion from sitting and the gap looks right on i think it's supposed to be 20 thousandths so that's good i'm going to try to clean up this cap the cap is pretty pretty bad inside so i'll just try to clean these posts a little bit and we'll see what we can do the spark plug wires have also pretty well had it you guys won't be able to see this but it's got spark real faint yeah see if she'll pop oh yeah she wants to run let's uh mess around with that cardboard a little bit see if she'll go all right here we go fuel got the throttle linkage freed up a little bit of choke see what she does well i tried to go let her sit for a minute might have flooded it aah don't you smoke that was too easy around the joke so there you go pretty easy she wants to run got the oil draining out of it now just topped off the coolant i don't have an oil filter so we're going to let that ride for now he said he just changed it before he put it in storage so yeah runs pretty good these spark plug wires are falling apart but other than that i think we've got all three cylinders so yeah cool gotta figure out where the water is going but i don't think it's going into the engine block so that's good news boy i don't see any sign of coolant or water in the oil so that's good and it looks pretty good really probably could have just left it for floor mat or rug yeah here thank you with uh buddy it has to have a signal 12 volt signal well should we drive it we might have to tune this carburetor a little bit but oh come here pup hey come here down yeah i get much better than that he's a clutch adjusted i think so [Applause] so it's pretty fast [Applause] you said that's actually one of the problems with these machines they're geared so high that they're not really useful as a crawler they were designed for field work hahaha it's so smooth yeah three-cylinder it's so smooth i mean it's smooth when it's running and working but it idle it just shakes this don't shake at all temperature gauge came up yeah you must got it warmed up it's smoking a little out of the breather 180 maybe yeah thermostat might be stuck is it charging don't know well cool [Applause] you're all right yeah the problem is i don't think it's it's driving on the one clutch or the one track so it it's going to want to go off to the side as it comes up the ramp you have to give it some english okay well because the rear axle is screwed up it's only actually driving with one track or putting power to one track so as soon as it gets on the incline it just wants to turn off to one side so we're gonna pull it with another tractor see how that goes of course the easy way would be to just winch it up on the roll back but some smart guy decided to sell it probably don't try this at home [Music] so so [Applause] [Music] hang on right that's good i didn't turn the pump on that's good enough it's on there what do you think kiddo [Music] all right guys made it back to the shop no problem this thing's pretty light i think without the belly pan and the loader and the counterweights and stuff on it i'd be surprised if it even weighs two tons so no big deal there you can kind of see now what we're up against on the on the rear end it's been leaking oil and you can see where the sprocket's rubbing against this final drive housing so probably some kind of bearing or something in here is is worn out and the whole sprocket is is leaned over kind of cambered over and then check this out they must have wanted to get this this cover off to pull the axle shaft out and they didn't want to pull the sprocket so they just they just fixed it by cutting a torch in a hole in the sprocket here for the cover to come out now the other side looks better i don't see any leaks it's like we do have some challenges ahead with the track adjusters somebody's welded a nut on here and looks like there's been some pipe wrenches involved i'm sure those threads are all seized up so that'll be fun i think he told me that he has new bolts for this he made new bolts for the adjusters so that's probably good the tracks are sagging quite a bit they're pretty loose it definitely needs to be tightened but i think we're going to have to split the tracks to fix the final drives so we'll deal with that when the time comes and i'm sure this one's been off before because i don't think they would have used you know window caulking from the factory so i don't really know how this system works i know oliver has two different types of steering clutches i believe there's what they call power turn which is a planetary system where the tracks both get power all the time even when they're turning just one goes slower and the other one goes faster and then there's what they call spot turn which is more like a a normal crawler where it stops one side and sends all the power to the opposite side i think this is a spot turn system but i really don't know so we'll let that drain for a little bit and then we'll pop that cover off well here's the diagnostic plan i've lifted the whole machine up and put it on some stands i'm going to start the engine put it in gear run it real slow then we're going to pull those clutch levers and just watch what's going on inside here and see if we can make heads or tails of it so so okay well that's not quite what i expected i think what's happening is one of the clutches is slipping all the time and the other one is not slipping at all does that make sense yeah i think so so i think that these roller cams over here are supposed to disengage the clutch so when you pull the brake band it should roll that that roller up onto that ramp and disengage the clutch that's not happening on either side but i think because the one side is slipping it's allowing you to turn only towards the side that slips all the time so yeah that's my thought anyway i don't know if there's any way to adjust that i need to need a manual and i don't have one so that's probably the next step all right guys i was able to get a hold of a service manual and it makes a little more sense now so these are cam actuated clutches so inside this drum is a multi-disc clutch here there's a couple of big belleville washers you know spring washers kind of like a pto clutch or an automatic transmission and there's no adjustment without taking them apart they're done with internal shims so i don't think we really have any choice except to pull this whole steering clutch unit out of here and that's no small job because in order to get the clutches out you have to pull the final drives which means we have to split the tracks there's a master pin somewhere we'll find that drive it out split the tracks off then we have to drop the track frames and that'll give us access to the sprockets and final drives and then i don't know about this inner frame here that's like the loader frame i guess or maybe that's part of the track frame anyway it looks like somebody's already done some carving in here with the cutting torch so they probably had this apart before and they just whittled this material out so they could slide the final drive out without removing this frame so if they did that once before we should be able to do it again anyway once the final drives are out you know so that'll pull this whole inner portion in here with the bearings and everything on it then we can just take the brake bands off and tumble this whole unit out the back but it's a major job essentially got to take the whole machine apart to get that stuff out of there and then once the clutch packs are out we should be able to you know relieve the spring pressure take the snap rings out and then see what we're dealing with but i don't see any way to do anything with it in the machine so so what i think we'll do is split the video here and in part two we'll tackle those steering clutches and i've looked around online there's very little information about fixing these old oliver crawlers there's you know some videos and stuff out there about them operating but very little about actually fixing them and yeah i think it's going to be a nice machine when we get it all sorted out this engine is fantastic it runs perfectly no smoke seems to have great compression has power the governor works the carburetor all i really did was just scrape the crap out of the bottom of the bowl and i didn't show you guys but the guy who owns this machine he actually made the emulsion tube in here for the high speed jet he machined it out of a piece of brass on a little collet lathe and the guy is a master machinist and he did a fantastic job it runs perfectly like that and i'm not 100 sure what to make of the whole head gasket issue i'm confident it does not have a bad head gasket and that you know the replacement job was done correctly as far as the oil level being too high i don't know all i can think is it was over filled i don't think it's possible for it to have fuel in the oil it's an updraft carburetor so that wouldn't make sense and the original fuel pump yield mechanical fuel pump right here that's all been disabled they were just running it off of a little gravity feed tank so yeah i don't know and the low coolant level you know that's pretty normal for machines that sit for a long time usually what happens is the hose clamps just you know expansion and contraction from heat and cool you get a little bit of a leak and then you know over 13 years eventually you're you're missing all your coolant so we're going to get lucky there the engine's going to be fine drivetrain okay but the steering clutches that's a whole other kettle of fish and then we're going to have some work to do out here in the final drives there's a lot of bearings and stuff that need to be shimmed and seals need to be replaced so we're going to have our work cut out for us but thanks guys for watching and i'll see you next time
