JD 450C final drive sprocket bearings
JD 450C final drive sprocket bearings
Right Final drive sprocket bearings went out this weekend. Pretty straight forward job I guess. I have a repair manual. But always good to get some extra knowledge. Do i have to jack up the rear area ? and any other inside look out fors would be helpful. Thanks.

Do you mean the bull gear bearings?
I've had the right final drive housing off mine. R&R'ing the track was the tough part.

Have not torn it down yet, but yes bull gear area i assume. Bearings seem to be worn out, lost final drive gear oil when it happened and lots of play in the drive sprocket. Do I need to jack rear side of dozer to remove drive sprocket to get to the bearings.?
Re: JD 450C final drive sprocket bearings
You should not have to jack the crawler. Locate the track master pin and position the pin at approximately the 9-10 position. You will have to split the track, remove the sprocket. You can make a special hanger, pictured in the tech manual, to lift and pull the final drive off. Best regards, Bruce

Have a spare master pin if you can find one. Sometimes they 'resist' coming out and require 'persuasion'.
ETA: My final drive was leaking because whoever had put the 5/8 bolts in, didn't torque them. Wasn't their only mistake assembling it but it was one of the larger ones.

I did mine a few years back. I blocked up the rear of dozer toward the center, then split track, removed final drive. Went by JD manual to rebuild, reinstall. Its been working fine ever since.
