Crankshaft Volvo B20 (-1973)

A worn timing chain that rattles on cold start, or leaking seals dripping onto the garage floor, are classic signs that the B20's moving parts are starting to tire. This category gathers parts for the rotating assembly in the 1986 cc engine (88.9 x 80 mm) on 1800 cars up to 1973.

During a bottom-end rebuild, the main bearing set and rod bearings are the natural starting points, often together with a piston set and piston ring set when the cylinder bores have been rebored. The group also includes a cam gear set to address chain rattle, plus seals and bolt kits that belong to the assembly. A good check point is to measure the crank journal wear before choosing the bearing undersize – that determines which set fits.

Keep in mind that the B20E with Bosch D-Jetronic and the carburetor versions share much of the bottom end, but always verify the spec against your engine.
