Connecting Rod Alignment
NOTE■
• Since the I.D. of the connecting rod small end bushing is the
basis of this check, check the bushing for wear beforehand.
1. Remove the piston pin from the piston.
2. Install the piston pin in the connecting rod.
3. Install the connecting rod on the connecting rod alignment tool.
4. Put a gauge over the piston pin, and move it against the face
plate.
5. If the gauge does not fit squarely against the face plate, measure
the space between the pin of the gauge and the face plate.
6. If the measurement exceeds the allowable limit, replace the
connecting rod.
