49 8N Rear Axle Seal Questions

Tonight, I took off the left brake drum, brake pads, springs, etc. Looking at diagram FO121 in the FO-4 manual, which of the seals would I need to replace to fix the problem.

The manual shows a gasket and a oil seal (outer) then a seal that fits into the bearing retainer is also called outer oil seal. When I took it apart, I don't remember seeing a seal in it. There is also listed an inner seal.

I'm pretty sure FO121 represents my tractor, just not sure what parts I should get to fix it.

Any help would be greatly appreciated.

Thanks for the info. I picked up the parts from a local dealer and should be working on it this week. I also picked up the cork seal for the Axle bearing.. so I'll soak it up about an hour before use.

Thanks again. I'll let you know how it goes.

#6 Oil seal retainer assy, outer, p/n A8NN-4248-A, consists of #7 Gasket, Outer Bearing Seal p/n 8N-4290, and #8 Oil seal Outer, p/n A8NN-4251-A.

When I replaced axle outer seal, it was cheaper to replace the entire #6 Oil Seal Retainer Assy, with p/n 8N-4251-C. (which has superceeded A8NN-4251-A or 8N-4251-B)

Be sure to have a lotta extra p/n 8N-4229-D shims (0.010) as some will invaribly be broken/cracked and there only about 50 cents. Make a deal to return your unused ones with the parts guy. Sometimes they'll sell you a paper gasket type instead of metal, eather works. Recommend you use some silicone pucky on the shims at the axle trumphet/brake backing plate interface for leak prevention.

FO-4 manual for adjusting clearances is pretty strait foward, just kinda distorted picture.

Also be certain to pack your 2N-4221, axle shaft bearing, with good longfiber tractor axle greese..... ...Dell
