4310 JD rear axle seal replacement

[Wesdor]

Thanks for the warning about naked photos. Those are impressive. You have me convinced that if this ever happens to me, I'll probably have the shop do it.

Nice work! And thanks for sharing this with all of us.

Maybe I missed it, but how old is your tractor - hours and years? I'm just wondering if this is something that happens often.

Thanks for the kind words. So many fine folks have made this board what it is (downright helpful). I'm just putting in my 2 cents finally. I've been lucky that my machine hasn't given me many problems considering how hard I use it.

Folks don't let this sway your opinion one way or another. I love my 4310 and I know that somehow sand got behind the seal retainer and sand will eat any seal on any machinery. I will be more careful in the future. I now have a 9' sickle bar to trim my pond.

Tractor only has 215 hours and is almost 4 years old. Never spent a day indoors until now.

I've got all the bolts removed and the housings just won't come off. They move about 1/4" in the rear but I guess the wet brakes or something is keeping them from coming off. I guess I'll have to go talk to the mechanic some more.

What was holding the housing on? Nice to know if there is a trick to
getting them off.

Not good that this happened at 215h. I notice that the front axle
seals are easy to violate, too. I recently replaced the front left axle
seal on a JD955 and I noticed that the cause was some nylon fishing
line got wrapped around the axle and got under the seal. The stuff was
invisible until the hub was disassembled. Funny thing is I probably could
have reused the old seal as it was not damaged.

Anyway, thanks for posting with all those nice pix. I am sure that you
feel rewarded by your accomplishment in addition to saving the $600
cost, to say nothing of the delivery and pickup fees.

Besides about 8 large bolts, the brake levers and differential lock lever connected to their respective jackshafts had to come off. Each was held on with a very tight roll spring pin. This was the most frustrating besides not knowing if they had to come off or not. I thought maybe the rear panel might have to come off but not so...

I hope my little extra gasket sealer may keep out excess dirt and moisture. To the rest of you with this type off machine, you can take off your rear wheels, remove the 3 bolts that hold the retainer on and clean out real good. I would recommend this if you operate in sandy or muddy conditions. This might save you having to do it the hard way like I did...Kyle

Nekked is right, is that a tractor?

No way to use a seal pull to save some tear down? Just curious.

Nope. Quite familiar with that tool and the Snap-on screwdriver handle type seal puller too. Flanges for mounting the wheel in the way...Kyle

ive got the housing back on, i just removed the left fender. did not remove the seat. i had no trouble getting the roll pins in and out. i bought my seal at bigon imp in taylor. it was 25$ . i could have pulled the seal out and matched it at an auto parts and saved 20$. not to bad a job overall.

thanks for all the help.
