Depending on the tolerances, as well as a possible spacer of the bearing, a shaft seal of conventional height can rest on the bearing inner ring. Experienced mechanics have so far solved this problem by grinding down the oil seal. The BGM shaft seal is a simple and practical solution. With the reduced height (3.5mm instead of 4.3mm) they offer 100% sufficient distance to the bearing in every engine. They are therefore compatible and applicable to any engine design.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 Vespajets 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 'spring' 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.TIP: Loctite oil seal adhesive keeps oil seals in place effectively, even in worn crankcases. The oil seals made of metal, from later PX models, can be retro-fitted to the GTR/TS/Sprint/V/Rally models motors, replacing the original rubber item. The deciding factor is whether the seat of the oil seal has a groove cut into the casing or not. The PX 200 crankcases produced by MALOSSI do not feature this groove, meaning they can also benefit from the use of this seal type.If this groove is present within the motor the rubber version must be used. Attention to this difference can be crucial for an oil-tight motor!OEM Numbers (for the purpose of comparison)  242550 - 112156 - B015668 (PIAGGIO)LML Star 125 2T/ DLX / Via Toscana / Deluxe1252T ACLML Star 150 2T / DLX / Via Toscana / Star / Stella / Belladonna RV1502T ACVESPA 125 GTR 125 VNL2T 2T AC `68-`78 145901 ->VESPA 125 TS 125 VNL3T 2T AC `75-`78 18139 ->VESPA 150 Sprint Veloce 150 VLB1T 2T AC `69-`79 294260 ->VESPA 150 Super 150 VBC1T 2T AC `65-`79 412374 ->VESPA 180 Rally180VSD1T2T AC`68-`73VESPA 200 Rally200VSE1T2T AC`72-`79VESPA COSA 1150VLR1T2T AC`87-`90VESPA COSA 1200VSR1T2T AC`88-`91VESPA COSA 1125VNR1T2T AC`88-`91VESPA COSA 2150VLR2T2T AC`91-VESPA COSA 2125VNR2T2T AC`91-VESPA COSA 2200VSR1T2T AC`90-`96VESPA P125X125VNX1T2T AC`77-`82VESPA P150 S150VBX1T2T AC`78-`90VESPA P150X / PX150 E150VLX1T2T AC`78-`85VESPA P200E / PX200 E200VSX1T2T AC`77-`83VESPA P80X/PX80 E80V8X1T2T AC`81-`83VESPA PX 80 E Lusso/ EFL/ Arcobaleno / Elestart80V8X1T2T AC`83-`90VESPA PX100 E100VIX1T2T AC`83-`84VESPA PX125 2011/ 30 Jahre125ZAPM741002T AC`11-VESPA PX125 CAT125ZAPM501002T AC`07-VESPA PX125 E125VNX2T2T AC`81-`83VESPA PX125 E '98 / Millenium125VNX2T2T AC`98-`05VESPA PX125 E Lusso/EFL/Arcobaleno / Elestart125VNX2T2T AC`83-`97VESPA PX150 2011150ZAPM742002T AC`11-VESPA PX150 E '98 / Millenium150VLX1T2T AC`98-`05VESPA PX150 E Lusso/EFL/Arcobaleno / Elestart150VLX1T2T AC`83-`97VESPA PX200 E '98 / Millenium200VSX1T2T AC`98-`05VESPA PX200 E Lusso/ EFL/ Arcobaleno / Elestart200VSX1T2T AC`83-`97VESPA T5 / Elestart125VNX5T2T AC`85-`90VESPA T5 Classic 125 VNX5T 2T AC `92-`95
