Buying and fixing an international 4700 with transmission problems

okay guys so I just bought this international 4700 so I got a pretty good deal on this truck and the reason is it needs a couple things the biggest thing to start with is there's a knock in the transmission I'm prepared to rebuild the transmission up in need to so this is a 1990 the interior isn't great but I really like the exterior of it it looks really nice so right off the bat I can feel that the clutch grabs really hard it's it's really jerky when you start at first here so you can hear that knocking it sounds like a motor nut but it's not as a matter of fact when you're in fifth gear it completely stops knocking if it's if it's not knocking in fifth gear there's a chance that it could be something in the transmission most likely the input shaft bearing so I'm prepared to do that if I need to it's not really that big of a deal but I'd rather just replace the clutch and be done with it so I can work with this when it's unloaded I don't really need to use the two-speed rear you know I just keep it in low until I get into fifth gear and then put it in high so and I'll go through all the gears [Music] [Music] that knock sounds pretty bad to watch gone it doesn't make a difference when I put them the rear end in in higher low it doesn't make any difference at all alright so in this inspection cover I can see some of what's going on but I can't see everything so there's three arms that hit against the throw out bearing I can stick my hand in and rock the throw out bearing a good amount and it makes almost the same noise that I'm hearing but I can see that there's some sort of fluid there too and the back of the motor is dry you can see over there is all dry so the only place that I can even see it is coming out of the shaft the input shaft on the transmission and it looks like maybe somebody just tried to grease it up it doesn't look like anything that's dripping it just looks like it's somebody greased it up maybe maybe to even try to stop this noise I'm not sure but we got a little bit more fluid here but inside it's dry so not sure where that's coming from could be just coming from this oil pan here but I gotta pull this ground strap I gotta pull this lever here I gotta pull a couple wires on the top for the reverse light and the speed sensor couple more ground wires take the PTO pump off and some more linkage and that's it and then I gotta take off the drive shaft I'll probably just try to take off this first shaft leave the second one in the rear end so it it'd be better if I had a lift but this truck is probably I don't know for a fact but it's probably twelve thousand pounds so an average lift isn't really gonna do it and my garage isn't tall enough and it's not wide enough to do what I need to do but that's okay where I'm sitting right now is actually where my new garage is gonna go and it's gonna be three car minimum so on the front of this PTO shaft I actually broke off the retaining screw for it so I'm gonna have to take this off from the back and then I'm just gonna have to deal with it when I'm pulling down the transmission the shaft is just gonna have to go with it I'm gonna take the driveshaft off just buy these these screws here [Music] you all right so these bolts wouldn't come out I tried putting a breaker bar with a pipe on it I I had tons of leverage I could not get that thing out so what I figured out is that I can just pull this out I can just pull the u-joint out enough it just gives you enough clearance to pass by if you take these bolts off and then you can just slide it aside so that's what I did for now I would have rather had it out of the way but this is fine okay so these sensors they just go to some clips right here so instead of taking the sensors out we can just take the clips off that way there's no chance of any fluid coming out [Music] keep it covered so I don't get dust in it this is the clutch pedal linkage so it's not easy to take it out from the transmission so I'm just gonna take this cotter pin out up here and then I can take this pin out and just let this flap and then it'll come out with the transmission so I just have to get everything from here back so this motor mount is fine I don't need to get that it's just all these bolts and so basically with this parking brake cable I just disconnect the disc and I'm gonna take these two bolts out here and then I'll just let this hang up here probably in this ground cable and this whole bracket stays on so the easiest way to take this linkage off this gearbox for the PTO you don't have to disconnect any of this you just take out this bolt right here and this bolt right here and then it takes off everything that's here okay so I just realized that if I take this bolt off of here then there's gears inside of there there's teeth and if you get it on the wrong setting going back in then it'll be out of adjustment so I could mark it out but I'm not even gonna bother I'm just gonna take this cotter pin off of here and I'm gonna take this rod out of here and then I don't have to worry about the guesswork all right so everything is disconnected so now I just need to worry about getting the bolts out of the transmission itself and then I can lower it down I got all the bolts out so now you can see the transmission is starting to separate from the adapter plate so I've got a transmission jack on here and I'm gonna slide this back and hopefully maybe I can find a way to hoist this thing up and that way I can work on the clutch without take it down in the transmission to take this pressure plate off I just have to take these bolts out 9/16 so there's plenty room from your work now I'm not gonna put my body underneath this jack just in case so that's why I'm working from the front with my feet up at the front of the truck this clutches shy [Music] [Music] [Music] [Laughter] [Music] so I was gonna press this bearing in but the press I have doesn't go this wide so I can't really use it so the next best thing is just fine the good driver for it and in this case this is a inch and a half and just gonna slightly tap it with the hammer [Music] okay so the guys at the transmission shop told me that this flywheel was really out of its limits as far as being able to be turned down so they said that I could I could turn it down as long as the bolts don't protrude enough from the flywheel to hit on the clutch Springs so they took they showed me how to test that and so basically all I need to do is elevate this up on something I'm just gonna use this off the ground a little bit that way the the bolts can go through and just sit there and you can also reach your hand underneath so basically all I need to do is take this new clutch and just set it in here then I have an old input shaft just slide this in here Center it and then you just spin this clutch and on the bottom you can hear that there's some play with the bolts so I'm gonna keep spinning it around until I feel it hit the bottom most portion so until it pushes that bolt down see when you're not hitting a spring like right there it's right in between so it's it went way up so I'm keeping tension on it and then I spin it around and then it pushes back down again and I want to find out where it pushes down the most which is right there it's it's hitting spring right there so then I lock it into place with my fingers pull these apart you can see I got quite a bit of space so I'm not even close to hitting these so that's great I mean a new flywheel was like $350 which is not the end of the world but I didn't really want to wait because then it's another day off for work I took today off just to do this so I wanted to get it done so it was only it was only 110 to spin this so that was good and usually they'll have a speck on it and they're usually be like a stamp and when you when you wear through that stamp that means you're you're out of spec but this one didn't have one either that or somebody already turned it down and ground that off one of the other but anyways it it works it's got plenty of space between the springs and the bolt and the worst case scenario really is that I'd have to grind down the top of all the bolts to make it work because you can see on top of this bolt there's these little ridges to tell you what great it is and if you grind those down you get like another 32nd of an inch so so these flywheels usually have like one volt that's misplaced on it it looks like it's further away from one hole but closer to the other so I like to find that one which in this case is this one and I'll put the first bolt in that I would rather be on the top of the motor at this moment but I'm not going to worry about turning it over [Music] so now I can't see you guys can but I can't see if these are lined up so what I'm gonna do is I'm gonna take my camera and I'm just gonna look in here with my camera so that I can see if things are lined up so once I get it close I can just stick this in and just ever so gently go back and forth until it actually threads in if this thing falls out it's not going to now but if it does in the alignment process I mean you could get seriously hurt from that so I like to usually put two in just to start with that one is all that's necessary and then I'll put my lock tight on the rest of them so in this case I'm using the red loctite I'm just gonna put a strip on it like this now these bullets are just great they're not torque to yield or anything like that [Applause] so now don't forget to take these two bolts out that you started with because they don't have a lot of time so just go put that on there so now it's hard to look up the specs on this kind of stuff on the internet but from what I'm gathering these are great 1/2 inch bolts and they should have a torque of about 80 pounds so I'm going to do that in sequences and with this lock tight it's not going anywhere even if it's a little bit low so I'm just going to do it until they're pretty snug in a crisscross pattern alright so now that they're all smoked up I'm gonna first bring them up to 40 pounds and then I'll switch to 80 so to stop this flywheel from spinning there's a hole on the bottom here like an inspection port so I'm just going to use a big prime bar that will help so the motor doesn't turn alright so now I'm going to bring it up to 80 alright so there's a lot of grease and dirt that I got on here so you definitely want to make sure that you clean that up I'm gonna use brake parts cleaner some guys don't worry about this but anytime you're working on rotors or flywheels or even the pressure plate you have to have it clean otherwise that oil can get impregnated into the into the disc and then it can make it have hot spots guys just so you know I didn't replace the crank seal on this I didn't show it on camera but I checked it out and it was fine the oil that you see in here it was from the it's actually grease and it was from the throw up bearing now when I went to the parts dealer I could have just got one and threw it in but it only took me two hours to drop this transmission so if I really need to do it I can do it and it's not that big of a deal so it's equally important that you also clean off the clutch disc surfaces as well as the pressure plate so I just did that and now I'm ready to put these in so I'm on the clutch itself it has a label you may not be able to see it but it right here it says pressure plate side so we know that this is a side that's gonna go here and so this is where this spine comes in handy just spline that in there just like that and now that kind of holds the pressure plate too now I need to rotate the pressure plate until the bolt holes line up and the pressure plate shouldn't have what the flywheel did where it has one bolt hole that's out of pattern so you should be able to just line them all up and put them in so right now all I'm trying to do is get these bolts snug so that this thing doesn't fall out of place and then it's very important whenever you're doing a pressure plate you don't want to start tightening down one side a lot before you tighten down the other side so you want to do a crisscross pattern and sequences and you'll see as you're tightening it up you'll see the springs tightening up and what could happen is if you okay close it down too much on one side and not enough on the other you can do damage to the springs and then the thing might not sit flat so I'm just getting these snug for right now and then I'll probably put them up all the 20 pounds and then 40 pounds you don't really need to do Loctite on the pressure plate bolts all right so before I put this clutch in this transmission back in I'm gonna check the input shaft bearing because I don't want to do this twice well there's the problem one of the problems anyways that's not good all right so when I have the front of the case on this bearing is set into place and then I can spin it so you can see I have one two two and a half two and there's a bunch of teeth missing on this so I'm gonna have to replace this countershaft drive here [Music] so that's all it is it just gets splined onto there that was really easy so now I just need to find a replacement part so there's a lot of numbers on here and that's gonna help me locate the new part see I actually have some numbers on this bearings I almost wouldn't even consider this a rebuild this is basically just a repair I've gone a lot more in depth with transmissions before I've had to take everything completely apart take everything off of the shaft all right so I'm just gonna explain it a little bit better about what happened to this transmission or what I'm pretty sure happened anyways so this is the input shaft and this goes right here this is where the power transfers from the motor to the transmission and then this is the counter shaft and here's the gear that went on here on the end of this input shaft there's a pilot bearing that goes in the flywheel so that's what keeps this from moving around side to side and that was completely gone there was not even any balls left from it it just had the races and that was it it was so loose that the input shaft just never was lined up right so because it wasn't lined up right when it was receiving power in first through fourth gear or reverse it would torque it one way or another and it just put things out of alignment just enough where it nicked these teeth and why it didn't break the teeth on the input shaft I'm not really sure but the input shaft seems to have very minimal damage to it I don't have to replace it I thought this was the clutch that's what the guy told me he told me he had a mechanic and that's what he diagnosed it to but I knew that that probably wasn't wasn't the case and just take it with a grain of salt so this was a very easy fix I'm very glad that this is all it took because usually to get this drive gear off the manual tells you to take the back cover off and basically you have to pull both the counter shaft and the main shaft in order to do that so that means taking these Forks out it means taking this PTO gearbox off it it's just a whole mess of things that you got to get into now I've gotten into that quite a few times with these transmissions not a Spicer I've never worked on a Spicer before it's not the end of the world and I was prepared to tear it completely down if I needed to the clutch and the flywheel were completely shot and the pilot bearing obviously too so we're just replaced throwout bearing and everything that went with it and I'm glad I did that even though that wasn't the problem it needed to be done to rebuild this including the fluid that goes back into it I probably have $250 so that's not too bad so this gear is an aftermarket gear and it was about half the cost of the regular one but the transmission shop said it was fine so I just went with it it was only like 80 hours for this gear which actually I thought was pretty good alright so on this input shaft bearing just gonna take this little cover off first then you can take this snap right now [Music] you [Music] [Music] [Music] all right so this CEO kick actually came with a couple different components it came with this little cap here that you put on the input shaft so that it doesn't scratch it up as it's going on and they gave you a little cardboard piece in the middle of protect it until you put it on too so they actually say to install this dry not sure why but I'll just follow it [Music] [Music] [Music] alright so I'm gonna take this for this first test run I'm gonna go to the gravel yards right down the road and I'm gonna get my first photograph with it [Music] [Music] [Music] so the gravel yard is only about five miles down the road all right so I just scaled in and I weighed 13400 this gravel yard is great I use these guys all the time and the price is really good too actually all right so I just got five tons in this for now quite a bit underweight but that's okay I just wanted to try this first one out because I just we've got this transmission you know I just want to keep it light for right now just make sure everything's up all right [Music] [Applause] [Music] [Applause] [Music] [Applause] [Music] all right so on my property here I'm running out of parking space over there so I want to make this little area over here like a parking area for vehicles that don't get used every day because I have like three or four of them that can go over here save me a lot of space over there you [Music] [Music] [Music] all right so the last thing I want to do on this I want to put some knobs on these these are the controls for the PTO for the dump these just don't have enough leverage because it was supposed to be like an extension on them and then there's also supposed to be a knob on them so my dad made a short video about making these on the lathe so if you want to watch that the link will be in the description and actually it's made out of spalted maple and it's the same tree that I made my kitchen cabinets with so all I did is take half inch galvanized pipe I drilled out this end just a little bit because it was there's like a weld in there and it makes it not fit over those nubs over there so then I just drilled out the middle with 3/4 inch bit and threaded this in I almost couldn't even move this before because it's so short and it hurt my hand so much so I'm just gonna put these on and now I have like an extra 8 inches of leverage on that thing and then this one this one's not too bad to do it but I figured I might as well match it anyways and this will let me feather it a little bit better it's so much better [Music] [Music] [Music] [Music]
