3-169. LUBE OIL PUMP - MAINTENANCE INSTRUCTIONS (Continued).
LOCATION

ACTION
REMARKS
INSTALLATION (Cont)
Always check the clearance between the crankshaft
gear and the oil pump idler gear with the engine
in the upright or running position.
If shims were used between the pump mounting feet and the bearing caps and new gears are not installed, the same
shims (cleaned), or the same number of new (identical) shims should be installed and the number
then adjusted to obtain the proper clearance between gear teeth. However, if new gears have been installed, a larger
number of shims will be required under the mounting feet. In either event, the pump must be tightened on the bearing cap
before the clearance between the gear teeth is measured.
