REPAIR INSTRUCTIONS Side Clearance Check
Backlash Check
Refer to Figure 244.
Refer to Figure 245.
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.
1. Check backlash between driving gear (3) and driven gear (2) with thickness gauge (1).
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. 244
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.
