specification, the assembly must be replaced.
Measuring Connecting Rod
(Small End Inside Diameter)
1. Insert a snap gauge into the upper connecting rod
small end bore; then remove the gauge and measure it
with micrometer.
CC290D
2. Maximum diameter must not exceed specifications.
Measuring Connecting Rod
(Small End Deflection)
1. Place the crankshaft on a set of V blocks and mount a
dial indicator and base on the surface plate. Position
the indicator contact point against the center of the
connecting rod small end journal.
2. Zero the indicator and push the small end of the con-
necting rod away from the dial indicator.
3. Maximum deflection must not exceed specifications.
Measuring Connecting Rod
(Big End Side-to-Side)
1. Push the lower end of the connecting rod to one side
of the crankshaft journal.
2. Using a feeler gauge, measure the gap between the
connecting rod and crankshaft journal.
3. Acceptable gap range must be within specifications.
Measuring Crankshaft (Runout)
