The adjustment of the clutch cover levers is
important in that if they are not all set the
same it will cause the release bearing to
wobble while disengaging the clutch and this
will cause accelerated wear on those parts.
Also the pressure plate will not engage and
release the disc evenly. This will cause a hot
spot on the pressure plate and can really
shorten the clutch life.

Since you were not able to get it to release
when first installed, like the tractor vet said,
you have one of two problems, installed
backwards, or the disc was bent on
installation.

The clutch cover assemblies coming from
Hy-Capacity are adjusted in a jig that results in
the lever height being correct within a couple
of thousands of an inch, much more accurate
than you are going to be able to accomplish in
the tractor. You can probably get the levers set
close enough to give you good service, but
first you have to determine the reason it will
not release. Since you ar sure that it did not
bind up while assembling, then the most likely
cause is the disk is in backwards. That has to
be corrected before you can make any
accurate adjustments.

When assembling the clutch to the tractor, on
those models with independent PTO and that
have a large enough hole in the bottom of the
clutch housing, it is easier to put the clutch
assembly on the input shafts and slide the
tractor together. Then, going through the
bottom hole, bolt the clutch cover to the
flywheel.

Check the disc in the flywheel before
assembling. When installed correctly there
must be some clearence between the front of
the disk and the crankshaft retaining bolts. If
not, either the disc is in backwards or the
flywheel is worn out.

To adjust the release levers while installed,
get one lever as close as you can. Adjust the
release bearing until you have .030 clearance.
(It doesn't make any difference what the
thickness is but you said that was your largest
feeler gauge. I usually use a piece of
keystock.) The adjust the other two levers until
they are all the same. With the engine running,
move the release bearing forward enough to
make sure the bearing is turning. The bearing
should not be wobbling. If it is you need to do
a little more adjusting.
