I pulled the bull pinion shafts today to
inspect their inner bearings. The right bull pinion gear had some chips on it so I
figured it was the one that had the failed
bearing. Turns out it was the culprit!
The bottom of the transmission case had a 8
in. long weld where a ball from a bearing
got caught under the bull gear. I don't know
the history on this tractor, but I am
wondering if this is the failed bearing that
caused this, or if this is another failed
bearing in this tractor's life.
Funny thing is, I would have never had
guessed all this was wrong with the
transmission when I was driving it around
earlier this year. Quiet tranny, no odd
noises. I only tore into it after I found
pieces of a ball bearing when changing the
rearend oil.
