Commercial anaerobic threadlocks have
installation instructions, and SAFETY CAU-
TIONS, on their containers. These should
be adhered to.
8. Reinstall and realign previously removed

5. Remove (4) 1/2” locknuts (Item 6) which are
factory retained with anaerobic threadlock
(eg. Lock-tite 242 (blue) or Perma-Lok HM
118 (red). Modestly pry plate (Item 7) out-
ward to start bearing (Item 1) off shaft.
6. A varying quantity of 2 3/16” nominal. I.D.
washers are factory installed between the
inner end of bearing (Item 1) and the shoul-
der on shaft (Item 5). Because replacement
bearings vary in axial dimensions, care
must be exercised to FULLY WASHER THE
SPACE BETWEEN THE BEARING AND
SHAFT SHOULDER. Reinstall plate (Item
7) and bearing (Item 1) by temporarily snug-
ging up 2 each of their bolts (without anti-
wrap shields). Visually check above cited
washers to insure no looseness, or substan-
tial axial preload, exists. 2 3/16 inch nominal
I.D. washers are available as part numbers:
Washer
Part Number
1/16” Thick
79202329
1/8” Thick
79202328
7. After the washers have been checked, torque
bearing mounting bolts and Allen set screws.
Torque the Allen screws once, loosen and
torque a second time. Reinstall anti-wrap
shields (Item 8) and torque support plate
bolts. See Photo DCP0575 on page 29.
