LUBE OIL PUMP ASSEMBLY - MAINTENANCE INSTRUCTIONS
(CONTINUED).
LOCATION/ITEM
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.
NOTE
When adjusting for gear tooth clearance by installing or removing shims, the same
number of shims must be changed under each foot so that the pump will always be level
on the main bearing caps. The insertion or removal of one .005 inch (0.013 cm) shim
will change the gear tooth clearance by .0035 inch (0.0089 cm).
