Step 22 Insert a 1/2” square drive 1.0” socket
down into the center of the lower idler
journal bearing. This socket is used as a
spacer/guide for the jack screw. Make
certain the 1/2” square drive hole is
pointing toward the thrust face of the
lower idler journal bearing (151C).
Step 23 Remove lower idler journal bearing. Use
a bearing puller. Thread two screws 1/4-
20 into the two top holes in the lower idler
journal bearing (151C). Screw the jack
bolt on the bearing puller down against
the 1.0” socket, and then jack (pull) the
bearing out of its location. Inspect the top
thrust face and the interior of the lower
idler journal bearing. If there are any
burns, rubs, deep scratches, replace the
bearing with a new item (151C).
