[Farmall] Clutch throwout bearing

[Mike Schmudlach]

 John,
I doubt that you did any thing wrong.  The old type bearings lasted 50 plus
years and some "expert" thought they could improve on that. I have heard a
zillion or more stories that match yours perfectly.  When they send you the
new bearing put in on the shelf and install the old type.  The next new one
will last just about as long as the other one you put in.   The old style
will last another 50 years.
Mike

Subject: [Farmall] Clutch throwout bearing

I recently replaced the throwout bearing on my Farmall Cub with one of the
newer roller bearing types. After only five months and probably less than 2
hours of  actual use, the bearing has completely disintegrated. The
manufacturer has agreed to send me another one under warranty. But, my
concern now is that possibly the bearing was not at fault but something more
sinister with the pressure plate or clutch disk. I was assured that hundreds
of the newer type bearings have been placed into service with no problems. 

So, my question is this. Does someone on the list have the technical
specifications for the clutch disk and pressure plate, like how thick should
the clutch disk be, what should the spring tension be on the actuator levers
on the pressure plate and how far should they extend outward from the
pressure plate, or any other information that would assure me that my clutch
is ok. I don't want to split my tractor but one more time.

Thanks for any help.

John Bailey
