Mount dial indicator on timing gear cover (1).

Point of dial indicator should

rest against side of a tooth on oil pump drive gear (2).

When measuring backlash, make sure that oil pump

idler gear (3) does not turn. If gear turns, back-

lash readings will be wrong.

indicator to read 0.

3.

Hold oil pump idler gear (3) so it cannot turn. Turn oil pump drive gear (2)

as much as you can in the other direction.

Read backlash between oil pump

drive gear (2) and oil pump idler gear (3).

If backlash is not between 0.006 and 0.014 inch, mark oil pump drive gear (2)

and oil pump idler gear (3) for replacement.
