6.
Adjust the clutch, using a 5/8-inch box-end or
socket wrench on the adjustment bolt. See
6.1
Insert the 5/8-inch box-end or socket
wrench through the inspection cover
opening.
6.2
To begin the adjustment, release the ad-
justment bolt by pressing down on the
bolt head.
NOTE: On Easy-Pedal 2000 clutches, each
complete turn of the adjustment bolt repre-
sents about 0.125 inch (3 mm) of release
bearing movement. On earlier Easy-Pedal
models, each complete turn of the adjust-
ment bolt represents about 0.02 inch (0.5
mm) of release bearing movement.
Normal wear increases the gap between the
release bearing and the transmission.
6.3
To decrease the gap
: If clearance be-
tween the release bearing housing and
the clutch brake is
more than
9/16 inch
(14.3 mm), turn the adjustment bolt clock-
wise (the release bearing moves toward
the transmission).
To increase the gap
: If clearance between
the release bearing housing and the
clutch brake is
less than
1/2 inch (12.7
mm), turn the adjustment bolt counter-
clockwise (the release bearing moves to-
ward the engine).
6.4
When the adjustment is complete, make
sure the adjustment bolt is locked (pulled
up flush with the mounting bolts).
7.
After adjusting, release the pedal and check the
clearance between the release bearing housing
and the clutch brake. When the adjustment is
correct, the green end of the tool should go in
and the blue should not (clearance of 1/2 to 9/16
inch, or 12.7 to 14.3 mm).
8.
Install the clutch inspection cover.
