REPAIR INSTRUCTIONS
Side Clearance Check
Refer to Figure 218. With the straightedge
positioned across the housing and the face of the
gears, check side clearance as follows:
r
Low Limit — Insert a 0.002-inch (0.051-mm)
thickness gauge between side of the gears
and housing. The gauge should pass
between gears and housing without drag. If
it drags, check the housing and gears for
nicks or burrs. Replace as necessary.
r
High Limit — Insert a 0.006-inch (0.152-mm)
thickness gauge between gears and
housing. The gauge should not pass
through. If the gauge passes through,
replace the housing.

Side Clearance Check
Backlash Check
Refer to Figure 219.
Check backlash between the pump gear (3) and
idler gear (2) with a thickness gauge (1).
r
Low Limit — Insert a 0.013-inch (0.33-mm)
thickness gauge between the pump idler
gear and pump gear. The gauge should
pass between gears without binding. If
binding occurs, check for nicks or burrs.
Replace as necessary.
r
High Limit — Insert a 0.028-inch (0.711-mm)
thickness gauge between the pump idler
gear and pump gear. The gauge should not
pass through. If the gauge passes through,
replace the gears.
