bearings

[metal finisher]

ive had my mt awhile but only have a tank and half thru it but why would i keep blowing the inside bearing on the middle shaft twice now the first time i thought a bad bearing put it back togther every thing turns smooth and straight ran about 5 mins. today and the same bearing went out again iam stumped ?

Are you talking about the bearing that holds the differential drive pinion, part 50074? I am also having run out problems with that bearing. What is the best bearing that we can put in there to give that shaft the support it needs?

Are you talking about the inside bearing on the shaft that holds the B/C gears on the gear plate? If so , if you overtighten the nut it puts excess stress on the inner bearing race and can cause premature failure.
