6.6 Adjusting The Breakaway Clutch
WARNING:
NEVER PLACE FINGERS INTO THE OPEN BREAKAWAY
CLUTCH OR YOU MAY BE INJURED SHOULD THE
CLUTCH SNAP CLOSED!
DO NOT TIGHTEN THE BREAKAWAY CLUTCH MORE
THAN WHAT IS NECESSARY! OVER TIGHTENING CAN
CAUSE DAMAGE TO THE BOOM!
The tension on the breakaway for the outer wing can be adjusted by
loosening or tightening the adjustment nut on top of the sprocket between
the inner and outer wings (Fig. 16).
1. If the breakaway clutch releases too easily, tighten the nut.
2. If the breakaway clutch is too stiff, loosen the nut.
Note:
Spring pressure from tensioned breakaway clutch only assists in
returning outer boom section to alignment.
3. Check that the lower nut (
D
)(Fig. 16) is fully tightened.
4. The breakaway wing section should pivot around the axle shaft
(
E
)(Fig. 16). Ensure that section (
F
)(Fig. 16) is free to move.
5. Loosen jam nut. (
B
)(Fig. 16).
6. Tighten nut (
C
)(Fig. 16) to stiffen clutch action. Clutch is properly
tensioned when breakaway boom section returns to alignment with
outer boom section after breaking away. Tighten jam nuts after
adjustment.
IMPORTANT:
Properly lubricate clutch assembly before adjusting
the tension. Breakaway clutch cap screws (A)(Fig. 16) must be
torqued to 40lb-ft (55 N-m) every week (40 hours) to prevent boom
damage. Lubricate every day (8 hours) to ensure maximum perfor-
mance and life.
