- Assembly
1.
Pack the caged needle bearing with grease, then
press into the outside of the pivot arm until it is flush
with the groove that houses the externally tabbed
thrust washer.
Check the innermost groove on the output shaft
which is located 2-1/4” (5.7cm) in from the end of the
shaft; make sure that the O-ring seal is present and
intact. This seal is important to keep grease in and
contaminants out. Replace it (Item 6) if necessary
(Fig. 170). Some models do not have this O-ring.

3.
Press the oil impregnated bushing into the boss on
the pivot arm until it is flush with the face of the boss.
If spring arm disassembly was required, install the
knob making sure that the detent is pressed out
about .060” (1.5mm). Install the spring arm knob so
that the concave side of the knob and the convex
side of the rivet align.
4.
Assemble the spring arm and pivot arm as shown in
Figure 171.

bushing from the pivot arm using an arbor press.

Removal of the grease fitting is not recommended
because it is pressed in. However, if damaged or
lost, we suggest tapping and installing a threaded
grease fitting.
