PRE-LOAD CHECK OF BEARING
(Cont)
j. A scale reading which exceeds the-specified maximum indicates binding of the bearing rollers, or
rollers improperly installed. When the scale reading is less than the specified minimum, the bearing is more
likely worn and should be replaced.
k. After the pre-load test is completed, remove the steel plates and attach the bearing retainer as
follows:
(1) Attach the bearing retainer (8) to the idler gear with six screws (6), and three screw locks (7).
Tighten the screws to 24-29 lb-ft (32.5-39.3 Nm).
(2) Bend the ears of each screw lock against the flat side of the attaching screw heads to secure
the screws.
