Crankshaft Volvo B4B

Low oil pressure, knocking main bearings or bluish-red exhaust smoke under acceleration are classic signs of a worn crank assembly in the small 1414 cc engine. When a B4B from the 444 years is being rebuilt, it is the rotating assembly itself – crankshaft, bearings, pistons and cam drive – that determines how long the motor lasts after reassembly.

This category gathers the parts around the work of the crankshaft and pistons. The group includes rod bearings and main bearing sets in several undersizes for a ground shaft, piston sets and piston kits with matching piston ring sets, a cam gear set for the valve train, plus spring washers and a flywheel bearing.

A common checkpoint during a rebuild is bearing clearance: the crankshaft's bearings can differ between model years and versions, so main and rod bearings should be measured and matched to the shaft's undersize before new sets are fitted – check which version your car has. The piston ring end gaps and the flywheel bearing play are likewise worth checking while the motor is apart.
