Widetrak Driven Clutch Components
Disassembly and Assembly Process
1. Install the clutch into the clutch compression fixture,
PN PU-50518. Slowly compress the helix down into
the sheave to gain access to the snap ring. Remove
the snap ring.
2. Slowly release the fixture arm to remove the helix and
spring. Disassemble the clutch sheaves.
3. Inspect the key, spring, bushing and clutch sheaves
for damage. Replace the bushing if more brass than
Teflon in visible.
4. Clean the sheaves with a Scotch Brite pad and a
solution of warm, soapy water.
5. Inspect the rollers for abnormal wear and replace as
required. Verify the spring tabs are in alignment and
parallel.
6. Assemble the clutch by sliding components down on
to sheave shaft.
7. Insert one leg of the spring into the hole in the sheave.
Insert the other spring leg into the #2 hole in the helix.
NOTE: Inserting the spring leg into hole #4 in the helix
will increase the amount of pre-tension in the spring.
While this may prevent belt slippage, belt burning or
engine over-revving may result.
8. Align the helix and stationary keyway. Compress the
helix down onto the shaft enough to prevent the spring
from dis-lodging from the helix and sheave, but do not
engage the rollers.
9. Hold the stationary sheave and rotate the moveable
sheave 1/4 to 1/3 revolution counterclockwise (until
rollers align with helix ramps).
10. Compress the helix down into the sheave. Install the
key into the keyway, then the washer, then finish with
the snap ring. Verify the snap ring is fully seated in the
groove with the sharp edge upward.
11. Carefully release the clutch compressor arm. Test the
clutch action by rotating the sheaves several times.
The moveable sheave should forcefully “snap” closed
when released.
