Bob ,
The biggest problem I see with that model is a
weak shoulder for a snap ring groove in the rear
end housing. The thru shaft for the PTO is supported
at the rear by a bearing that is held in place by
two snap rings, the rear snap ring groove shoulder
is too thin to stand the end load on the shaft and
it breaks , the oil turns metalic and requires
that the housing be completely empty to repair.
Of the seven of that model that I know the local
dealer sold , only one has not failed . Of the 6
failures , I fixed 5 of them and another shop did
the other one .The fix requires setting up on a
horizontal boring mill to bore out the remains of
the hole, fabricate a new hole with snap ring groove
and press in place and pin in place to prevent
the sleeve from comming out .
