Examples of Common Warranty Exclusions
1. Check for a warped alloy bell housing
2. Examine tubular dowel pins for damage during tting of bell housing or for
missing dowel pins.
3. Examine gearbox quill/gearbox main drive nose cone/bearing slide:
Excessive wear can cause bearing to come in contact with the cover
assembly diaphragm unevenly while actuating the clutch.
4. Ensure the proper mating of bell housing to motor, and crankshaft to
ywheel. These may not mate properly due to debris, grease or other
parts in the way of the mating surfaces.
5. Examine all bearings/bushings for excessive wear, replace if necessary.
6. Replacement engines and gearboxes may have missing dowel pins.
Ensure that you remove pins from your product when you send your core
for remanufacture, and ret or replace them when installing new clutch.

General Misalignment Issues/Tips
Diagnosing Bearing Noises
1. Clutch release bearing
A. Depress the clutch pedal approximately
2”. the bearing is now in contact with the
diaphragm. Should the bearing rumble or
squeal then the clutch release bearing is most
likely at fault (providing it has been pressed
onto the carrier the right way around.)
2. Pilot Bearing or Bush.
A. With engine running depress the clutch fully.
B. Select rst gear.
C. Release the clutch.
If the squeal is heard at the point of the clutch
taking up, then the pilot bearing is faulty. In
the event it is a bronze bush it will indicate
lack of lubrication on the I.D. of the bush. If
the bush has been lubricated on the I.D. there
is a greater possibility that the O.D. of the
bush is under sized and worn. The noise is
then caused by the bush spinning in the end
of the crank. If new pilot bush has not been
pressed in evenly this could also result in the
bush spinning which would cause a grumbling
or squealing noise. Pilot bush noises are more
apparent when engine and transmission are
cold. (i.e. In the morning).
3. Front gear box bearing
A. Drive the vehicle at approximately 25 mph
in gear. If a noticeable grumble noise is
apparent, depress the clutch pedal to the
ooor. This will, in turn, stop the main drive
and bearing from spinning. If noise ceases it
is probable that the front gear box bearing is
faulty (as there is no load on the bearing).
