2X C14531 Seal (as of late we were not happy with Ingersoll provided seals, so we upgraded to these industrial seals). Here is a Seal kit for your tractor or loaders rear end. (Not Backhoes) For early rear ends 200,400, 600 loaders. Look at the photos to make sure your rear end is the "EARLY" style. We also have kits for the later flared axle tubes.
OPTION- To add one  C13196  Gasket For Rear End Cover
 
This kit is for rear ends on tractors with the straight axle tube ends NOT the flared large end tubes - look at photos. These axles are found on most  1978 and earlier tractors and loaders. BUT CHECK YOURS. Later rears with flared axle tubes  kit HERE
 
We highly recommend replacing all the axle bushings and seals at the same time. Worn axles, bushings and seals can lead to rearend and or axle failures. There should be little to no up and down or back and fourth play and movement in your axle. Also, there should be no leakage when filled up to rear fill plug height with oil. If you have a failed seal, it is also likely the axle bushings are worn, too, and that's why the seal failed.
