Check the pump vent (Fig. 61). The vent must be
secure. Replace the pump body if the vent is cracked,
broken, or loose.
Inspect the pump bushing (Fig. 61). Then check the
reaction shaft support bushing. Replace either bush­
ing only if heavily worn, scored or damaged. It is not
necessary to replace the bushings unless they are ac­
tually damaged.
Install the gears in the pump body and measure
end clearance with a feeler gauge and straightedge
(Fig. 62). Straightedge should be resting on pump
body as shown:
• End clearance between outer gear and straight­
edge should be 0.010 to 0.063 mm (0.0004 to 0.0025
in.).
• End clearance between inner gear and straight­
edge should be 0.025 to 0.177 mm (0.001 to 0.007
in.).
Measure tip clearances with feeler gauge (Fig. 63):
• Clearance between inner gear tooth and outer gear
should be 0.08 to 0.19 mm (0.0035 to 0.0075 in.).
• Clearance between outer gear and pump housing
should also be 0.010 to 0.19 mm (0.0035 to 0.0075
in.).
