bearings, installing


Note:

Only replace complete sets of connecting
rods
Do not interchange connecting rod bearings.

Checking radial clearance - Before removing, mark positions of connecting rod bearing caps with a
felt pen or similar.
- Remove connecting rod bearing cap. Clean bearing cap and bearing
journal.
- Place a length of Plastigage corresponding to width of bearing on
bearing journal or bearing shell.
- Install connecting rod bearing cap and tighten to 20 Nm. Do not rotate
crankshaft.
- Remove connecting rod bearing cap again.
- Compare width of Plastigage with calibrated scale.Clearance when new
