CLEANING AND INSPECTION
CAUTION
Care MUST BE taken when handling clutch
actuator rod. The locating pin is free and will fall
out, allowing compression springs and shims to
fall out.
1. Clean clutch actuator rod in solvent and dry with
compressed air.
2. Insert Cross Pin Tool (91-86642) between com-
pression springs in elongated slot in clutch rod.
3. Compress both springs by forcing cross pin tool
back-and-forth in elongated slot. This will release
any initial set from springs.
4. Measure distance from each end of elongated
slot to the near side of cross pin tool. The mea-
surement taken must be equal within 1/64
″
[.016
″
(0.4mm)].
5. If measurements (taken in Step 4) are not equal
to within 1/64
″
, disassembly of clutch actuator
rod must be performed to determine the reason.
[Reasons for unequal measurements may be a
broken spring, a spring of reduced length (see
Step 6) or the wrong spring shimming.]
6. If disassembly is performed on clutch actuator
rod, spring length must be 1.535
″
to 1.560
″
[1-17/32
″
to 1-9/16
″
(38.9mm to 39.7mm)].
