MX4700 tractor split need help removing seal

[markpaul2929]

Hey guys I had oil leaking severely from the split pin plug. Called the dealers and he said its most likely the 4wd seal and the tractor needed to be split. They wanted too much so i decided to do it myself. It was my first split. It was pretty straightforward had to disconnect few hydraulic lines and electrical connections. kept the steering, dashboard panel and all the main wiring and hydraulics connected and just onbolted the main dashboard bolts and pulled it off with the engine. all in all a couple of hours. Now the issue is how do i remove that 4wd seal?

Also is the main transmission seal (inside the aluminum housing) leaking and what is the process with it for replacing it? Reall only found oil on 4wd shaft

see attached photos

Also how can i tell if the clutch did not get oil on it? Do i have to remove clutch cover? And if i do how do i align the transmission spindle?

Not sure on your tractor but on a L48 which is probably similar, it was a bit of a pain getting that shaft out. I had it split behind where you did also at the clutch housing. Ended up hammering out the shaft with that section of housing on the floor held up on blocks of wood. You might luck out and be able to remove the shaft just by pulling on it or getting creative with a slide hammer. Pay attention to the parts diagram if there are any spacers that might fall off behind that seal.

On my L5240, I took two regular screwdrivers and heated the tips with a torch. Once they were red hot, I bent the last 1/8" over at a 90 degree angle. Once I pierced the seal, I used the hooked end to pull out the seal.

A word of warning. Get some help. I have heard that if the shaft is removed, whether on purpose, or by accident, it can be a bear to get back in place. I had my father apply constant pressure to it so that it did not come forward.

Also, we jacked up the front of the housing quite a bit. This kept the fluid that escaped to a minimum. We lost maybe a 1/2 gallon in all.

Do yourself a favor and replace the input shaft seal also while you have everything apart.

Thank you sir for the help. The input seal, is it in the aluminum housing where the throw out bearing is? Also does the housing have a gasket that needs to be replaced when opened? Again thank you for the help.

How many hours on these tractors when this seal goes? sounds like I'll have the same problem sometime now that mine just 1000 hrs.

1600 hours. if you are handy it takes a couple of hours. Don't take it to the dealer.

My L5740 was 860 hours when it failed.

Mine had around 850 hours. If you can pull it off in a couple hours on your first attempt then my hat is off to you. It’s probably easier on a bare bones tractor because there’s probably less stuff to take off, but it’s still a pretty decent job. I figure it can be done in a weekend. I carefully hammered a screw driver in the center of the seal. Once it was bent it was easy to get a screw driver on the outside and pry it out.

How did you remove the sleeve? (Item number 050) see attached diagram
