SECTION 5: Adjustments (continued)
d. Apply power to the unit and check for clutch slippage.
NOTE: When clutch is not slipping, entire clutch will rotate as a single unit.
When clutch is slipping body and cone (number 3, Figure 8) will not rotate with
the other parts of the clutch. Small amounts of clutch slippage can be difficult
to determine. To aid in providing if the clutch is slipping, use a grease pencil
or felt tip marker and draw a line across face of nut (number 6, Figure 8) and
along body and cone (number 3, Figure 8). If clutch is slipping, the line on nut
(number 6, Figure 8) and body and cone (number 3, Figure 8) will move
relative to each other.
DO NOT LET CLUTCH SLIP ANY LONGER THAN NECESSARY OR
CLUTCH MAY HEAT UP RESULTING IN UNPREDICTABLE OPERATION
AFTER IT COOLS.
e. Repeat steps a through d until there is positively no clutch slippage.
5.3.5. Lubrication:
a. Clutches are grease packed at the factory and should not require additional
lubrication. If clutch is subject to consistent slippage and heating, remove pipe
plug (number 9, Figure 8) and insert your standard grease fitting, lubricate with
Lithium EP grease. Do not use air pressure gun!
