Product description
Thecrankshaft is the heart of your motor and really takes a beating.Crankshafts in engins with a lot of mileage on them or piloted by speed freaks often have the bearing and shaft gasket hubs shrink or the connecting rod bearings are loose. With every motor service thecrankshaft should be replaced.We only carry high qualitystandard crankshafts
.MAZZUCCHELLI andTAMENI
, made in Italy – both from the Milano region, have manufactured first class and reasonably priced Vespacrankshafts for decades. The Portuguese producerJASIL
, also known asTOP RACING
, advanced in the past years to a top address in crankshaft productions. He is in no way inferior to the italian manufacturers.
Appearance, quality and timing are at all the same as thePIAGGIO original.To top this, theTAMENIshafts have very good pressure measurement. Some shafts, such as the ETS crankshafts and the PK automatic shafts are originalPIAGGIO shafts.TheETS crankshaft is clearly a highlight and struts it’s stuff with an intake timing of 126??. The flywheel side bearing and shaft gasket hub is additionally reinforced and thicker. When used in a V50/PK/PV/ET3 motor casing, a conversion bearing/shaft gasket ring is necessary. All crankshafts are delivered with the upper connecting rod bearings. For those who like it sporty, go for a racing shaft. They offer not only a longer intake timing, they additionally have a polished special con rod ‘Messerpleuel’ with a high quality silver bearing.Conclusion
: Solid and good products. Perfect for overhauling motors and effectual with decent tuning.Crankshaft / stroke 51mm / piston rod 97mm / 24/25mm, M12Crankshaft with 82mm crankweb (flywheel side), 87mm crankweb (rotary valve side), 97mm piston rod with 2 additional lubrication bores, oil seal housing 24mm, bearing housing 25mm, stump cone with M12mm thread, incl. piston rod bearing
New bearings, oil seals and keys are a must. Same goes for sealing kit, clutch-, and flywheel nuts. It also makes sense to use the crankshaft tools # 27338000, # 21071000 and # 18119000. If you are using a V50/PK/PV/ET3 crankcase, you need an oil seal for conversion bearings.OEM numbers (for comparisons):
