I have discovered a gear oil leak on my JD 650's hub assembly. Am I correct in thinking it is part # 16 which has gone bad? It's the only seal I can see on the parts diagram that might cause such a leak. There is also an O-ring that is part # 14. I'm trying to have the parts on hand being that I have to order them online before I tear it apart is why I am asking here. Any help would be appreciated, thanks!

ozziemo27; I can't tell for sure about that type, mine is clear different, it's a 2520, that I help u with as I have tore mine apart to fix several different items. somebody tomorrow will follow up and help u, I'm sure. good luck. big jim

 

ozziemo27, If I were to tackle this project I would probably acquire items 14 through 20 before I tore it apart.

 

I would at the very least replace all seals as long as you have it apart.

 

Yes # 16 is the seal causing your leak. #15 is a liner that fits inside the oil seal and the last I checked are no longer available from JD.
If the liner has nasty groove, PM me. You really don't have to get into #14 but there is an o-ring seal on #22 you might want to get.
My 2 cents.

 

Thankyou! I don't see any part #'s listed for an O ring for #22, any idea where I might find it? It looks like both #16 and #15 are available online. I'll order #16 and tear it apart this weekend.

 

John Deere - Parts Catalog
It's listed under "Power Train" section 95 Front Axle Shaft, item 6. They call it packing

Thanks! You were spot on. Got everything ordered, #15 was a bit scored up, decided to just replace it and be done with it.
