Spring Pressure Adjustment
4. If spring length is correct and the measurement is not
the 7/16" allowed, insert or remove the appropriate
amount of the .030" (.762 mm) spacers (Part No.
515200) to obtain the correct measurement. See
Figure 30.
5. On right side of unit, install trunnion roller assembly
onto clutch shaft by aligning the timing marks ("0").
With the "0" on the trunnion roller facing the cam,
align the "0" on the roller with the "0" on the shaft.
Slide assembly onto the clutch shaft. See Figure 31.
NOTE: f the "0" on the shaft is not visible, align the "0" on
the trunnion roller with the first groove to the right of
the keyway on the shaft.
If the timing marks ("0") are not properly aligned, the
cut-off will not operate properly. The timing on the
cut-off revolution will not be correct and will cause
premature and/or erratic cut-off.
THE "O" ON SHAFT IS
THE FIRST GROOVE
TO THE RIGHT
OF THE KEYWAY

7. With set screws and brass plugs removed from
adjusting nut, install adjusting nut onto connecting
rod and tighten until pressure plate and brake lining
are tight against housing.
8. Place the "O" ring into position over the thrust bear-
ing and install the lubrication fitting.
9. On left side of cut-off, install clutch lining (replace lin-
ing if necessary), flywheel and sprocket.

ADJUSTING PRESSURE
1. Insert the locking screw partially into the end bolt,
using a lithium based lubricant, or an anti-seize com-
pound on the threads. Tighten the screw until hand
tight.
NOTE: If locking screw is not into the end bolt far
enough, the end bolt threads will strip when shim-
ming flywheel.
2. Install end bolt (with locking screw inserted), washer
and shim pack, placing the thicker shims onto the
outside of the end bolt.
3. Tighten end bolt and torque to 75 ft-lbs. (102 N·m).
Tighten locking screw.
4. Using a feeler gauge, measure the distance between
flywheel and clutch lining to determine how many
shims to remove to obtain .005" (.127 mm) clear-
ance. See Figure 33.
