Crankshaft Volvo B23

Oil leakage behind the flywheel and increasing oil consumption are classic signs of a tired cranktrain in a B23 – the 2.3-liter four-cylinder OHC motor fitted in the Volvo 240 in several configurations (B23A, B23E, B23F). At high mileage the main and rod bearings develop play, piston rings lose their seal and the crankshaft seals begin to leak.

This group includes pistons, piston ring sets, main and rod bearing kits, seals, support plate, timing belt pulley and lock rings – the part families that belong to a thorough motor rebuild. A typical checkpoint during disassembly is the bearing clearance: measure the crank journals and main bearing positions against specification before choosing standard or oversized bearing shells, so the new rod bearing set gets the right clearance.

Since the B23 came in different configurations, it pays to verify the motor code and detailed measurements before picking parts, so that piston diameter and bearing kit match your specific motor.
