Various types of roller bearings are used in the Vespa's engine: Thrust bearings, Tapered roller bearings and needle roller bearings. We refer to them collectively as engine bearings. They all possess minimal friction values and therefore produce little heat, require less lubrication and are virtually maintenance-free. The only thing that can shorten their life-span are contamination, a heavier than average work-load or a lack of adequate lubrication with a suitable oil. The stronger the state of tune or the higher the mileage a motor has achieved, the more frequently the engine bearings require replacement. We recommend engine bearing renewal during every major engine service or 10000 km (6250 mls.)
Most of the engine bearings we have available are original PIAGGIO items and in order to extend the range , we also have most types of bearings available, that we buy directly by the various manufacutrers.
SIP-TIP : Do not forget to order new crankshaft oil seals and gasket set when replacing the bearings of your Vespa's engine. For a quicker and more professional job there are also specialist tools available specifically for this purpose.
If your flywheel can be moved up and down while completely installed it's time, at least, to replace the flywheel side crankshaft bearing. A new crankshaft should never be used in combination with the used, existing bearings.
If you operate the clutch while the engine is running and the flywheel hits its cover, then its time to change the clutch side crankshaft bearing. A new crankshaft should never be used in combination with the used, existing bearings.
The bearings mounted on either side of the crankshaft in many earlier Vespa models are identical. There is a reinforced bearing available for models of Vespa produced since 1951 that has 9 ball bearings. For tuned motors we recommend the new reinforced SIP Premium / Performance bearing, also as a 9 ball bearing, made in Japan.
