5488 split and rebuild.

Recommended Posts

So I’m finally getting around to splitting the 5488 to replace clutches. We were working it and it stopped moving. We removed the implement and it would move but found clutch teeth in the filter housing. 
So I’m going to split it between the speed and range transmissions roll engine and speed out from under cab and separate speed trans from engine with an aframe. 
Will I need to separate the range trans also or will I be able to do what is required with it in chassis. 
when I get things tore down I’ll get a kit hopefully from 88series restorer to repair. 
 

Thanks in advance, John

You can leave range on rearend and do clutch from there.  Just have solid support under range and drawbar in back.  Also have good support under cab front corners.  Don’t use bottle jacks as they will leak down over time.

Rolling the speed trans out with the engine will allow to rebuild the hi-low clutch packs and the rest of the speed transmission. The master clutch will stay with the range transmission, but will be accessible, but you will be working under the cab, unless you chose to remove the cab, which is really not needed unless you need to do more work to range trans or rear end.

What were you going into the range transmission for.......reverse shift collar/gear or synchronizers or??? 

Thought it maybe a good idea to just look everything over after this happened.

I would say that was a close call , but would you think a near miss tip over would require a tear down???  I guess I'm lost on this one

Iirc his tranny locked up or something like that to send the tractor into a tail spin hopefully IHC5488 chimes in on this. I dont remember what he found was wrong but I remember reading his thread

I'm probably the minority, but if I'm working in the speed transmission And the range transmission, I'm pulling the cab. I've done it both ways and yes, it takes time to R&R the cab, but everything else is So much easier.

Thanks for all the info guys. I’ve got 20 x100 lb weights on the front. When I pull the speed trans off the engine is it likely to topple over forward. 

Thx, John

I always set a jack stand under weights, largely because I am to lazy to remove them.

Boxcars no MX series yes as it's so quick and easy. The worst thing is removing the hydraulic pump group on all of them. Why oh why didn't the engineers see fit to make pump drive idler gear drop out of there leaving the pumps in place.

It will 100% tip over, been there done that. No damage, just thrilling. Four weights off and was fine.

I leave all the weights on whenever I split.

BUT!!!!!!!

I made a square tube channel that goes thru the weight handles, 2 bolt holes on each end which then bolts to a set of frame/plate screw jacks similar to ones used at the back of engine when splitting at that location.  The 2 Jack's at the weight location are also tied together near the bottom with a steel strap to keep them from spreading apart.

do you think my master clutch is toast. This isn’t the reason we split it. Still more to come. DCD56158-D80F-4843-93FE-3BEBC64D73E1.thumb.jpeg.d8ed3b5befe15d49fd7437771511f54e.jpeg

Well on your way....nice shop to work in, plenty of light.....

Clutch looks........ Like toast.....

Did you have any trouble getting the cab mount bolts out of the frame of the cab....that threaded square that sits in between the tranny and cab frame had to be the worst idea ever.
