Crank bearing set with metal seals from SIP for classic Vespa PX scooters.

This particular set has the larger seal supplied in metal.

These items wear out regularly and should be replaced during every strip down of your engine. If the motor has not been run for a while the seals could be damaged. If the revs of your motor increase while it should be ticking over, the oil seal on the flywheel side of the crankshaft is probably defective or damaged. If you discover fuel mixed with your gearbox oil, the oil seal that sits on the clutch side of the crankshaft is the likely suspect.

Bearing size = 25x62x12mm & 25x38x15mm

Seal size = 24x35x6mm & 31x62x5.8mm
