Low oil pressure, knocking from the main bearings or high oil consumption are typical signs that the crank mechanism in a B17 is starting to wear – and it's rarely a single part that needs replacing. This category gathers the parts that belong together when the lower end of the motor is rebuilt or overhauled.

The group includes rod bearing sets and main bearing sets for clearance control against the crankshaft journals, pistons and piston ring sets for the cylinder bores, plus seals that seal the crankshaft ends. There are also a support plate, screw and timing belt gear that belong to the assembly around the crankshaft.
During a full overhaul it's worth measuring the bearing journals before choosing bearings – sets are often available in standard and undersize. Always replace the rear crankshaft seal while the motor is apart, since it's hard to reach once everything is back in place and a leaking seal quickly soaks the clutch.
