NSERT ThE OUTER bEARINg RACES
Lightly grease the front and rear bearing bores.
Insert the outer races of the front and rear bear-
ings into the gearbox as shown in Figure 35.
Ideally these races should be pressed in using an
Arbor press and an old bearing race ground down
to slide freely in the bearing bore. If this is not
possible, a soft drive rod (wood or brass) may be
used to install the outer races. Note: before you
install the outer race for the front bearings, you
must place the shims in the bottom of the bore
of the gearbox as shown in Figure 36. For new
shafts, use 0.100” of shim and for used shafts
use 0.10” of shim. (Older style gearboxes will
require no shims with a new shaft and 0.00” of
shim with a used shaft.)
