1 Insert conrod bearing shells into conrod bearing cap, fit on conrod bearing cap with conrod bearing shells and tighten conrod screws to the tightening torque.
2 Measure conrod bearing in direction of conrod and note the measurement obtained.

3 Measure conrod bearing journal and determine conrod bearing radial play.
Determining conrod bearing radial play
Measurement -conrod bearing
- Measurement -conrod bearing journal
= Radial conrod bearing play
If the measurement obtained is not within the permissible tolerance, the conrod bearing radial play can be corrected by replacing the conrod bearing shells, aim for the mean value of the specified radial play.
4 Unscrew conrod bearing screws and remove conrod bearing cap.
