FIGURE 19. CLUTCH LINKAGE ADJUSTMENT
ADJUSTING THE OIL CLUTCH
PEDAL
The clutch pedal must be adjusted so that the pedal
arm does not touch the bottom of the floor plate. See
Figure 19. There must be 1.6 mm (0.0625 inch) clear-
ance between the top of the pedal arm and the bot-
tom of the floor plate. The distance from the top of
the floor plate to the bottom of the pedal pad must be
136 mm (5.38 inch). To adjust the height of the pedal,
loosen the lock nut that is on the capscrew on the
shaft bracket. Turn the capscrew until the pedal height
is correct. Tighten the lock nut.
When the clutch pedal height is correct, adjust the
clutch release linkage. The pedal must move freely
13 mm (0,5 inch) from its stop to the point where the
release bearing touches the pressure plate levers.
Remove the pedal return spring. Move the pedal up
and down and measure the travel between the points
of resistance. Adjust the length of the threaded rod to
change the amount of movement of the pedal. Loosen
the lock nut on the rod. Remove the cotter pin from
the dowel on the pedal arm. Pull the rod from the
dowel. Turn the rod to change its length. Install the
rod on the dowel and measure the pedal travel. In-
stall a new cotter pin when the pedal travel is correct.
Install the pedal return spring.
