Assembly
NOTE:
The top and bottom trunnions are very similar

being that shims
28
are installed to the top trunnion
only.
1.
Tap the drive shaft inner bearing
33
Figure 8-8 into
position in the hub swivel drive shaft bore. Secure with
retaining ring

to
eliminate end float but without bearing pre-load, that is,
no increase in spring balance reading.
9.
Measure the gap at the top trunnion and subtract 1 mm
(0.040 inches) to give shim thickness (bearing pre-load).
For example:
NOTE:
If the gap measures 1 mm (0.040 inches), then no
shim is required.
If after installing the shims, the bearing pre-load is
not attainable, install new bearings.
