Check the gear lash by installing a bolt, or equivalent, in the impeller puller holes. Measure the lash with an
indicator at that point. The gear lash setting should be .0015 inch to .0045 inch (0.0038 to 0.0114 cm). When
the specified lash cannot be obtained, loosen the pump attaching bolts and move the pump up as required to
obtain the correct gear lash. Retighten the mounting bolts. A .0015 inch (0.0038 cm) movement of the pump
directly away from the camshaft will increase the lash .001 inch (0.0025 cm). Likewise, moving the pump
toward the camshaft .0015 inch (0.0038 cm) will decrease the lash .001 inch (0.0025 cm).
