Various types of roller bearings are used in the Vespa’s engine:
Tapered roller bearings, and
Needle roller bearings.
Collectively referred to 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.
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.
