BACKLASH MEASUREMENT
NOTE:
Do not install the water pump compo-
nents when measuring the backlash.
Measure both the forward and reverse
gear backlashes.
If both the forward and reverse gear back-
lashes are larger than specification, the
pinion gear may be too high.
If both the forward and reverse gear back-
lashes are smaller than specification, the
pinion gear may be too low.
If either of these conditions exist, then
check the pinion gear shim(s) selection.
