22. Place the shaft sub-assembly on the press bed.
Coat the inside diameter of the bearing and the
bearing journal on the shaft with Loctite Primer
N and #609 (or equivalent).
Carefully, lower the rear bearing retainer sub-
assembly in place on the shaft. Do not allow the
seal lip to come in contact with the Loctite.
Ensure the notch in the bearing and the dowel
pin are aligned. If external snap ring (16) was
installed in the bearing retainer, ensure the
opening is aligned with the dowel pin.
Press the bearing onto the shaft until it reaches
the shoulder of the wear sleeve. Wipe any
excess Loctite from the assembly.
Ensure the seal lip is dry. The seal must
remain dry for proper sealing.
Spin the bearing retainer approximately 25
times to burnish the teflon seal on the wear
sleeve. Check for abnormal sounds or other
indications of contact between the retainer/seal
assembly and the
interference is found, remove the bearing
retainer and eliminate the point of interference.

Loctite Primer N and #609 (or equivalent) on
the straight end of one pitot tube (3). Coat the
tube to approximately 20 mm (0.75 in.) from the
end.
