2520 Front end seal. Need help please

bz1 · Jul 6, 2011

My dealer machanic seemed to indicate the problem is with the seal part #2 that shows in the latest diagram you attached. I'm just going by where he was pointing when he told me about it. But, I never did see whether you found the leak was on the stub axle shaft or on the steering pivot. I suppose either one could leak especially since the oil is filled up half way into the differential case.

I think it's #2 seal.
That is where it looks like i'm losing fluid.
Stopping by Deere over lunch to exchange parts.
Thanks guys.

Spindle shafts seals aren't bad either. I just replaced them on my 955 a week ago. Very similar design. Took about an hour per side.

I have a 2720, looks very similar. leak is coming from the spindle seal by the looks of it. Is there a posted process for removal and replacement? Do just the 8 bolts in the case need to be removed to remove the spindle? Will the seal need to be (hydraulic) pressed in/out? I'm assuming that I should get part #7 gasket at the same time if I'm pulling the 8 bolts on the case. TIA

Thanks for all of the information and posts here. I have also a leak on the front axle of my 2520. However, I believe it is originating from the top of the gear case (21) in above diagram. In order to trouble shoot I am guessing that I will have to take the whole thing apart from steering arm through gear case but am hoping to leave most of the gear case in tact.

I have never done this and was wondering if anyone has any good step by step instructions for this. Unfortunately we can't afford to take it in every time we have problems and need to learn to fix this ourselves.

Once again, appreciate all the great posts on this site. Cheers.
