High-precision BGM PRO auxiliary shaft axis for the primary drive bearing of the Vespa P 200E, Rally180, Rally200 models.
Made of extremely strong and tempered 42CroMo4V steel.
Qualitatively not comparable with cheaper replicas.
This means that the primary drive can be repaired to 100% factory specification.
Mandatory equipment for tuned engines.
INFO: The auxiliary shaft axis has a bearing surface on which the needles of the generator-side primary bearing run. While the needles hardly ever wear out, the bearing surface on the auxiliary shaft axis should be inspected more closely every time the engine is overhauled. Traces of pitting (material breakouts) can often already be found here. The auxiliary shaft axis should then be changed, including the needles.
