Inspection of Connecting Rod
1. Measure the wrist pin bushing bore using a bore gauge
(1, Figure 199). Replace the bushing if not within
specifications. If the bushing has been removed, measure
the inside diameter of the connecting rod small end (2,
Figure 199). See "Connecting Rod" on page -99 for
specifications.
2. Place the connecting rod bearing inserts into the
connecting rod and connecting rod cap. Install the rod
cap and tighten the bolts to the specified torque.
3. Measure the inside diameter. See "Crankshaft" on
page -98 for specifications.
Inspection of Tappets
1. Inspect the tappet contact surfaces for abnormal wear (1,
Figure 200). Normal wear will be even as shown in (2,
Figure 200). Slight surface defects can be corrected using
an oilstone.
2. Measure the outside diameter of the tappet stem (1,
Figure 200). See "Tappet" on page -100 for the service
limit.
