MEASURING THE BACKLASH

NOTE:
Do not install the water pump compo-
nents when measuring the backlash.
Measure the forward gear backlash.
If the forward gear backlash is larger than
specified, the pinion gear may be too
high.
If the forward gear backlash is smaller
than specified, the pinion gear may be too
low.
If either of these conditions exists, then
check the pinion gear shim selection.
1. Place the shift rod in the neutral posi-
tion.
2. Install the dial gauge onto the lower
case.
3. Install the backlash indicator on the
drive shaft and have the dial gauge
plunger contact the specified point.
