snapring. Measure the dimension from the
bearing shoulder inside the carrier to the farthest
edge of the snapring groove and compare with
below.
Clutch Size Maximum Width
6-1/2” – 8” clutches .700” (17.78mm)
10” & 11-1/2” clutches .814” (20.68mm)
or .891” (22.63mm)
• The bearing fit may be a sliding fit, but must be
snug. A slightly tight fit is desirable.
Facing Discs:
• Must be free of oil or grease. Must not be
burned. Once burned, they normally are
incapable of holding torque.
• Measure the amount of wear that has occurred
on each friction surface (2 surfaces per facing
disc). Total wear allowable in any clutch (add 2
or 4 surfaces together) is approximately 1/4”
(6.35mm). Thickness of a new facing plate is
.375” (9.53mm).
• Teeth must not be worn excessively or broken.
ASSEMBLE THE CLUTCH:
1. Assemble the sleeve and bearing sub-assembly.
• Install the release bearing (H26) in the bearing
carrier (H27). The fit should be a snug sliding
fit or a light press fit.
• Install the internal snapring (H29).
• Press the release bearing onto the release sleeve
with the snapring located on the side nearest the
three bosses of the release sleeve. Be sure to
press against the inner race of the bearing - do
not support, press or tap against the outer race
(bearing carrier). Damage to the bearing could
result.
• Install external snapring (H28).
• Place two links on one side of the bosses of the
release sleeve (one on either side of the boss).
The travel stop protruding from one side of each
link should point toward the bottom of the
release sleeve and must rest against the release
sleeve.
• Install the clevis pin (H31) through both links
and the lever boss.
NOTE: The clevis pin must be installed as
previously noted so the head will lead the direc-
tion of clutch rotation.
• Securely install the retainer (H32) in the groove
of the clevis pin.
• Repeat the previous 3 steps to install links on
the remaining 2 lever bosses.
2. Assemble the clutch body sub-assembly.
• Place the clutch body (H1) on the bench with
the friction surface up.
• Install three separator springs (H36) in the
spring pockets of the clutch body.
• Place one facing plate (H4) on the clutch body.
• Thread the adjusting ring (H9) into the pressure
plate (H3) almost to the bottom of the thread.
• Place the wear ring in the adjusting ring.
3. Install the release levers.
• Position the three levers (H13) in the lever
bosses with the protruding tang against the wear
ring up and the “long end” up.
• Press down on the pressure plate to compress
the separator springs and allow the clevis pin
(H14) to be inserted through the lever and
clutch body.
NOTE: Be sure the clevis pins are installed so the
heads will lead the direction of clutch rotation.
• Securely install retainers (H15) on the clevis
pins.
4. Install the release sleeve and bearing sub-
assembly on the clutch.
• Position the sleeve and bearing sub-assembly
on the clutch so the links align with the levers.
• Align the clevis pin holes and install a clevis pin
(H33) through the links and levers so the head
of the clevis pin will lead the direction of
rotation during clutch operation.
• Securely install the retainer (H34) in the groove
of the clevis pin.
• Repeat at remaining lever positions.
• Install the lever spring over the release bearing.
Locate a connector of the spring over each of
two levers, and then stretch the spring to get it
onto the third lever.
• Using the drive ring as a gage, perfectly center
the facing disc(s) relative to the clutch body.
• Engage the clutch by pressing the release sleeve
and bearing down to the stop. If the facings are
not clamped tight, disengage the clutch, rotate
