(a) Clean oil and dirt from cover with mineral
spirits and allow to air dry.
(b) Sand pressure plate surface lightly with fine
emery cloth.
(c) Lubricate release lever pivots and check re
lease lever height. Adjust height if necessary.
CAUTION: Apply lubricant to pivots sparingly. Exces

Clutch Slippage Or Inadequate Clutch Linkage Free Play
Clutch slippage can be described as a condition in
which the engine overspeeds but does not generate any
increase in torque supplied to the wheels. Clutch slip
page occurs when the driven plate is not gripped firmly
between the flywheel and clutch cover pressure plate
and rotates or slips between them at high torque. Clutch
slippage can occur during initial acceleration or during
subsequent shifts. Check clutch operation as follows:
(1) Block wheels and apply parking brake.
(2) Operate engine until it reaches normal oper
ating temperature.
(3) Shift transmission into third gear and increase
engine speed to 2000 rpm.
WARNING: Do not permit anyone to stand in front of
the vehicle during this test.
(4) Slowly release clutch pedal until clutch is fully
engaged.
CAUTION: Do not allow the clutch to be engaged for
more than 5 seconds at a time as the clutch components
could be damaged.
