Rearend, Rear Axle, Rear End Bushing And Seal Kit

Used on early rears (look at photos) 200, 400, 600 series machines ( For 644 Backhoes, and 646 Before Serial Number 9758386 confirm your 646 backhoe part numbers in correct book) For Later 646, 648, 6000 and 7000 look at our other rear Axles kits.
 
Including all in one kit:
X2  C16744  OUTER Bushing
X2  C12713  INNER Bushing
X2  C14531  Seal (as of late we were not happy with Ingersoll provided seals, so we upgraded to these industrial seals)

OPTION- To add the Hi/Low shift rod Seal C13266 
OPTION- To add Brake Drum Shaft Seal C12531, Outer Bushing C13385, C13241 Inner Bushing.
           (NOTE- On some rears some very light honeing, sanding etc light material removal may be
          needed to install new brake bushings only on some rears.)
OPTION- To Add 2 Axle Retaining "C" Clips 
 
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/backhoes. BUT CHECK YOURS rear and your parts book. 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.
