6. Measure the flattened plasti-gauge using the
gauge wrapper (Figure 114).
7. If the thickness of the plasti-gauge exceeds
0.012 in. (0.31 mm), replace the bearings. If
the bearings do not exceed the criteria, the
bearings can be reused.
Note: New part clearances are as follows:
• Series 3000: 0.001 in. (0.025 mm) - 0.005
in. (0.13 mm)
• Series 3600/4200: 0.002 in. (.05 mm) -
0.005 in. (0.13 mm)
Installation
1. Apply clean new oil to the new connecting rod
journal bearing (inner diameter only) (Figure
115).
2. Slide the bearing (Figure 116) into the con-
necting rod from below the crankshaft journal.
3. Apply oil to the inner surface of the cap end
bearing.
4. Properly orient the grooves and install the
bearing in the rod cap.
5. Place the two capscrews into the rod cap.
ATTENTION
The journal bearings have tabs that match the
inner diameter of the connecting rods. Ensure
the bearings are properly oriented in the tabs
when installing (Figure 117).
