Step 23 (continued)
Step 24 Remove socket head cap screws (905M)
and lock washers (154D) from lower high
speed journal bearing (151A). Remove
thrust washer (155A) by lifting up and off
the lower high speed journal bearing
(151A). Inspect the thrust washer for any
burns, scratches or rubs. If any of these
conditions are found, replace the thrust
washer with a new item (155A).
Step 25 Remove the lower high speed bearing
(151A) by tapping (with a soft mallet) on
the bottom of the bearing. Inspect the
lower high speed journal bearing for any
rubs, unusual wear marks or scratches. If
anything appears abnormal replace the
lower high speed journal bearing (151A)
with a new item. If the bearing checks out
good then tag bearing as lower high
speed bearing (151A), so it does not
become mixed up with the upper high
speed bearing.
