Refitting ( Removing

) 1. Place the piston-connecting rod assemblies (1a), complete with half-bearings (1b), back in their housings using a suitable fitting tool.

The piston - connecting rod assemblies are fitted in the cylinder block/crankcase so that the discharge on the piston skirt is in line with the oil jet fitted on the cylinder block/crankcase.

Place the connecting rod bearing caps, complete with half-bearings, back in their housings and fix them tightening the bolts to the recommended torque.

The connecting rod caps are fitted so that the number stamped on them is facing the same side as the one stamped on the big end (inlet side).
