Sealing box rear crankshaft end early model B20F

Rear Crankshaft Oil Seal – Volvo PV, Amazon, P1800, 140, 164, 240, 740, 760, 940

Rear radial oil seal for the crankshaft, fitted on the clutch side. The seal seals the crankshaft against the rear crankshaft seal housing and prevents engine oil from leaking out towards the clutch.

When replacing the clutch, it is recommended to check the oil seal and replace it if necessary, as oil leakage can end up on the clutch disc.

Important for older Volvos

Older Volvo PV, Amazon, P1800, 140 and 164 may originally be fitted with a felt ring seal at the crankshaft. On these engines, this radial oil seal only fits if the engine has already been converted for a radial oil seal, or if the engine has the later version from the factory.

For engines that still have the older felt ring seal, a conversion kit is required to convert to a radial oil seal.

• Part 1218634 is manufactured in Sweden by CVR

Good to know

When the gearbox and clutch are removed, the rear crankshaft oil seal is easily accessible. This makes it a good opportunity to replace an old or leaking seal at the same time as the clutch.

Also check the crankshaft sealing surface for wear or grooves before fitting the new oil seal.
