twelve turns and tighten the locknut up to the
inlet manifold. Torque to 60 ft-lb (81 N.m).
c. Lubricate the support pin (35d) with Gear
Reducer Oil (43). Install the pin with the coun-
tersinks facing up, into one side of the frame
base (50). Place one nylon spacer (27d) on
the end of the support pin.
d. Install the bearing (14d) and manifold (32) and
align them with the support pin (35d).
e. Tap the pin in flush with the opposite side of
the frame. Align the second nylon spacer with
the support pin, and tap the pin all the way into
the side of the frame base (50).
f. Tighten the two setscrews (17b) onto the
support pin (35d). Torque to 35 in-lb (4 N.m).

Replacing the Lever Arm on the Frame
CAUTION
Tolerances between the surface of the frame and
bearing are very close. Do not force the pin into
place. Check for burrs on the pin or in the VRHC
frame if the pin does not slide into place. Sand with
500 grit sandpaper between the countersinks.
NOTE: Refer to Fig. 18 for Steps 1 to 5.
1. Screw the locknuts (2) onto the pivot bearing (15).
2. Screw the pivot bearing into the frame base (50).
Adjust the distance from the top of the support
pin (33) to the bottom of the frame (50) to 26.125”
(664 mm).
3. With the bearings at the correct height and parallel
to each other, torque the locknuts (2) to
60 ft-lb (81 N.m).
4. Place a generous amount of lubricant (43) onto the
support pin, and place the lever arm (49) over the
bearings (15).
5. Slide the support pin, with the countersinks up,
through the lever arm and bearings. Torque the
two setscrews (17) to 35 in–lb (4 N.m).
NOTE: If no drag is felt while turning the setscrews,
replace them.
