Crankshaft Volvo B20 (-1973)

Rattling bearings on a cold start, rising oil consumption and low compression are classic signs that the crank assembly in a B20 is getting tired. This category gathers the parts involved when the bottom end is rebuilt on a 122 with the B20 motor up to 1973.

The group includes main bearing sets and rod bearings in various undersizes, piston sets and separate piston ring sets, a cam gear set plus seals and screw/bolt kits for tightening to the correct torque. During a bottom-end rebuild, bearing clearance, crank pins and cylinder bore wear are typical checkpoints – always measure up before ordering the correct bearing undersize. The B20 was available as the B20A and B20B and arrived in August 1968 for the 122's final two model years, so check the motor variant when selecting parts.
