Thoroughly clean all of the parts. Put oil on all

of the parts.

If the bearing was removed from the timing

gear cover, install a/new bearing with tool (A).

Install inner rotor (2) and outer rotor (1) in the

timing gear cover.

Measure the clearance between the rotors with

a feeler gauge. The clearance must be .002 to

.006 in. (0.05 to 0.15 mm). The maximum

permissible clearance is .009 in. (0.23 mm).

NOTE: Make a replacement of both rotors if the

clearance is not correct. The rotors can not be ordered

separately.

Put the plunger and spring in position and push

the guide into the cover with a press until the

lip on the guide is even with the finished

surface on the cover. Make sure the flat

surface on the guide is in alignment with the

setscrew. Tighten the setscrew.

Put cover (3) in position on the timing gear

cover. Install the locks and bolts (4).
