Main Bearing Cap Removal
[211 JA]
Before removing main bearing caps, ensure they
are marked so they can be reinstalled on the
same journals. Keep the bearings with the same
cap and tag, or mark them to identify the cam
side of the bearings.
Refer to Figure 122.
1. Remove eight buttress capscrews (2 and 3).
2. Remove main bearing capscrews (1) from
each of the seven bearing caps (4 and 5).
The center main bearing cap (5) houses the
thrust washers.
3. Position a lady-foot pry bar under the tabs
provided on bearing caps and pry bearing
caps upward. To work them loose, it may be
necessary to tap the bearing caps
alternately from side to side with a soft
mallet.
