Measuring Connecting Rod Side Clearance

Measuring Connecting Rod Side Clearance

Using Dial Indicator






- Mount dial indicator to a stationary point on the engine. Locate the probe perpendicular to and resting against the connecting rod cap being checked.

- Move the connecting rod all the way to the rear of its travel.

- Zero the dial indicator.

- Move the connecting rod forward to the limit of travel and read the dial indicator. Compare the measured side clearance to the specification. Refer to => [ Piston, Pin and Ring Specifications ] [1][2]Piston, Engine.

- Repeat this procedure for each connecting rod. Rotate the crankshaft for connecting rod accessibility.

Using Feeler Gauge






- Slide a snug-fitting feeler gauge between the connecting rod and crankshaft journal flange. Compare the measured side clearance to the specification. Refer to => [ Piston, Pin and Ring Specifications ] [1][2]Piston, Engine.

- Repeat this procedure for each connecting rod. Rotate the crankshaft for connecting rod accessibility.
