REPAIR INSTRUCTIONS

Side Clearance Check

Refer to Figure 244.

1.Low Limit Insert a 0.003-inch (0.076-mm) thickness gauge between side of gears and housing. Gauge should pass between gears and housing without drag. If it drags, check housing and gears for nicks or burrs. Replace as necessary.

2.High Limit Insert a 0.0045-inch (0.114-mm) thickness gauge between gears and housing. Gauge should not pass through. If gauge passes through, replace housing.

Backlash Check

Refer to Figure 245.

1.Check backlash between driving gear (3) and driven gear (2) with thickness gauge (1).

a.Low Limit Insert a 0.006-inch (0.20-mm) thickness gauge (1) between pump driven gear (2) and pump driving gear (3). Gauge should pass between gears without binding. If binding occurs, check for nicks or burrs. Replace as necessary.

b.High Limit Insert a 0.016-inch (0.40-mm) thickness gauge (1) between pump driven gear (2) and pump driving gear (3). Gauge should not pass through. If gauge passes through, replace gears.
