1.
Thoroughly clean all of the parts. Put oil on all
of the parts.
2.
If the bearing was removed from the timing gear
cover, install a new bearing with tool (A). Make
sure the joint in the bearing is installed in the
position as shown in illustration.
3.
Install inner rotor (2) and outer rotor (I) in the
timing gear cover.
4.
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.
5.
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.
6.
Put cover (3) in position on the timing gear
cover. Install the locks and bolts (4).
7.
Check the oil pump end clearance with a feeler
gauge. The end clearance must be .004 + .002
in. (0.10 + 0.05 mm).
NOTE
If the clearance is not correct, make a
replacement of BOTH rotors or cover
(3). The rotors can not be ordered
separately.
