520H rear wheel axle seal and bearing

[Jake Collie 3]

Hello all.

Was in the shed last night and noticed an oil pool under the left rear tire on the 520H. Looks like I will be changing the axle seal and bearing. It appears I will have to take the whole transaxle apart to get to the bearing. Is this correct?

Thanks.

Bearing yes disassemble... seal only not necessary.  jack her up and remove wheel.  Try moving axle up down front to back .  Shouldn't wiggle.  if it does bearing will have to be replaced.  Some in and out movement up to about 1/8"" is OK

Thanks for the reply. Unfortunately the axle moves up and down. Looks like a ball bearing inside and needle bearing outside. Time to get oily.

Needle bearing is B-1816   Seal is SKF 11124   I do not recall  the ball bearing # off hand. (my tractors are all older)  But they are less prone to failure..

Inner bearing is 6008-C3

 

Edit That is # if eh inner bearing is a needle bearing.

Inner bearing is wheel horse # 111199 and is a 40mm ID ball bearing.

Thank you for the other numbers.

If you have a lot of play there is a good chance that the axle is knackered.  The axle is hardened and ground in the bearing area and that cannot have even minor damage.
