Housing Alignment Pins
Installation of Bearings into Front and Rear Housings:
2
Insert bearings (3A & 3B) into the housing bores, while aligning the grooves for the bearing lock
pins.
NOTE:
If the bearings have not yet been removed from the
front and rear housings, refer to
Step 12
of the disassembly
procedure (see Page 18). The bearings normally require a
light press fit to insert them into the housings. A mechanical
press can be used to facilitate this process (see photos).

3
Insert the bearing lock pins (25) into
the front and rear housings.
NOTE:
The pins serve to prevent the bearings
from rotating. They are normally made of Teflon.
Metallic pins are available for high temperature
applications.

Insert two housing alignment
pins (24) into the front housing,
as shown.
NOTE:
The pins should have a slip fit into the
housing. The housing pins serve to accurately
align the front, center and rear housings.
