Runner Turbo Connecting Rod for motorbike

Connecting Rod

The connecting rod is made of forged steel. It has a Tee-shaped base on which the crank bearing is attached with hydraulically tightened bolts and nuts with Penn-securing. The L90GBE engine has shims placed between the base and the crank bearing, as this engine type needs a smaller compression chamber because of a higher compression ratio. The top is square shaped on which the crosshead bearings are attached with hydraulically tightened studs and nuts with Penn-securing. The bearing parts are mutually assembled with bolts and nuts tightened by hydraulic jacks.

The lubrication of the crank bearing takes place through a central drilling in the connecting rod.

The crank bearing is made of steel cast in two parts and lined with white metal. The bearing clearance is adjusted with shims. The crosshead bearings are made of cast steel in two parts and provided with bearing shells.
