Oil Seal Set engine

for Vespa 150 GS,
20x40x6/ 20x40x6/ 35x47x7 mm

Radial shaft oil seals should be installed firmly into the crankcase for a tight and secure fit. The inner circumference of the ring is the contact point to the rotating shaft and is mostly held in place with a circular spring to keep it sealed tight around the shaft. These items wear out regularly and should be replaced during every service of your motor. 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.

We have oil seals produced by several manufacturers available, constructed using a variety of materials. The blue and black versions are made of a synthetic rubber, the blue type mostly produced by CORTECO are a little tougher than the black type which can be found in most engines as an original PIAGGIO component. The brown seals are produced using a fluoro polymer material (FPM) are especially heat resistant (up to 160°) are harder wearing with more resistance against oil. Both types see wide spread use in all two -stroke motors.

Here at SIP there is no consensus amongst us as to which type is best, so we have solved this problem as PIAGGIO has done and stock all colours and types to keep everybody happy.

Helpful hint: As a rule of thumb, to ensure correct positioning of your fresh oil seals, the 'open' side of the seal always faces towards the one of the chambers that it separates, with the higher pressure. This higher pressure also helps the inner circumference maintain the seal to the shaft by pushing the inner edge against it.


SIP-TIP: Loctite oil seal adhesive keeps oil seals in place effectively, even in worn crankcases.


We have engine shaft oil seals available from PIAGGIO, PASCOLI and RMS. We here at SIP also compile some of the kits. We all rely on the supply of oil seals produced by either CORTECO, ROLF or other major engine oil seal manufacturers in order to put these kits together. Later PIAGGIO produced engines are provided with clutch side crankshaft oil sealing spring that are made of metal. The PASCOLI versions have an 'o' ring instead. This ensures that we have more than one set of oil seals available for every engine that belongs in a Vespa, which helps ease supply bottlenecks that can arise when dependant on an individual manufacturer. The Vehicle Identification Numbers (VIN) provide by PIAGGIO, PIAGGIO Vintage and PASCOLI do not always correspond with that of the specified oil seal necessary for certain earlier models of Vespa so check and compare the exact dimensions of the existing oil seals correspond with the ones to be ordered.

The rounded or squared recesses displayed in the design of the oil seals in earlier Vespa engines helps the cooling and lubrication of the adjacent bearings. The relative shape of the two designs is irrelevant as they are interchangeable.
