23. Inspect the crankshaft gear (Q) for broken or worn teeth.  If

the crankshaft gear does not need to be replaced, it does not
need to be removed.  If the crankshaft gear is damaged,
remove the crankshaft gear with the Flywheel Puller

(PN 2871043).

24. Install the two puller bolts (R).  Tighten the puller bolts up

so that the bolts are at equal length.

25. Install the Flywheel Puller (

PN 2871043

) and remove the

crankshaft gear, if needed.

26. Rotate the water/oil pump gear (S), so that all four bolts are

visible though the gear.  Remove the four bolts with a hex
wrench.  Pull out the pump.

27. Inspect the oil pump rotors for wear.  Mark the rotors with

a white pen to ensure upon reassembly that the correct sides
of the rotors are installed and mesh with the same edges as
previously installed.

NOTE:  If replacing the old rotors, new replacement
rotors will fit into the original oil/water pump
housing.

28. Use a feeler gauge to measure the clearance between the

two rotors.  Measure the gap between the two rotor tips as
shown below. 

The clearance should not exceed 0.006"

(0.15 mm)
