Step 18 a.
Remove and inspect the upper high
speed journal bearing (151B) and the
upper thrust washer (155B) from the
bearing plate (102). First remove hex
head cap screws (905N) and lock
washers (154E). Next pull high speed
journal bearing (151B) from bearing
plate (102). Save shim (158). When
inspecting the bearing look for rub
marks or uneven wear marks. If the
bearing has scratches or dings or any
unusual wear replace the upper high
speed journal bearing with a new item
(151B). If the upper high speed journal
bearing checks good tag the bearing
as upper high speed journal bearing
(151B). This will help insure it does not
become mixed up with the lower high
speed journal bearing. Inspect the
thrust washer (155B). If there are any
burns or rubs replace the thrust
bearing (155B).
Step
19
Remove idler shaft (A140). To do this the
mechanic must lift the high speed shaft
(A130) slightly while pulling the idler shaft
(A140) up and away from the high speed
shaft (A130).
