2.
Slide the clutch brake tight against the transmis-
sion input-shaft bearing cap.
IMPORTANT: Release bearing travel tool A02-
12419-000 is available through the PDCs. The
fork at one end of the tool has green tape on it,
and has two 0.50-inch (12.7-mm) diameter tips;
the fork at the other end has blue tape on it,
and has 0.56-inch (14.3-mm) diameter tips. See
3.
Measure the release bearing travel. See
for the correct dimension to measure. Using both
ends of the release bearing travel tool, check this
gap as follows:
Position the tool so that the legs of the fork at
the blue 0.56-inch (14.3-mm) end straddle the
transmission input shaft. If the tool fits loosely,
the gap is too wide and adjustment is needed.
Go to the next step.
If the blue 0.56-inch (14.3-mm) end can’t be in-
serted in the gap, then try to insert the green
0.50-inch (12.7-mm) end.
If the green end of the tool can’t be inserted in
the gap, adjustment is needed. Go to the next
step.
If the green end of the tool fits — snugly or
loosely — then no adjustment is needed. Nothing
more needs to be done. Install the clutch inspec-
tion cover.
4.
Turn the engine flywheel until the lockstrap is
aligned with the clutch inspection-cover opening.
5.
Release the clutch by depressing the pedal.
Block the pedal in the released position, or have
someone assist you by holding the pedal down
during the adjustment procedure.
NOTE: An open-end wrench is not recom-
mended for the following step.
