JCB 3C2 - Rear axle seal questions?

Yozza · Post #1 by **Yozza** » Mon May 12, 2014 10:35 pm

Hi folks,
My rear axle seals leak like a good un, just had to put 2 gallons of oil back in the box :shock:

Do any of you knowledgeable folk know if I can get away with taking the rear wheels off and replacing the seals with no serious dismantling? If so, are these seals listed on fleabay the correct size and type?

Thanks

Can't fit the seals without pulling out the half shafts.Have to remove the rear cover off the diff housing to then remove the nut on the end of the shaft to pull it out.Would think the bearing will need heated/pulled off the shaft to allow the seal on then.Not quite sure.
The correct seals will be imperial.If you convert the sizes above(apart from the width) to inches,they are slightly different to the pt no. ATJ1024,which is for Leyland tractors but should be the same as JCB.

Thanks for the answer. Sounds like a biggish job, I'll keep toping up the gearbox oil.

Cheers,

Done this job and from memory agrimax is correct. I think there are two seals on each side.
