Important: Difference to early auxiliary shafts

Early gearbox types (e.g. VBB, Sprint) used auxiliary shafts that originally worked with pointed needles. These pointed needles are hardly available today. As a replacement, they are usually converted to the modern needle type with rounded ends.

The round needle type requires an auxiliary shaft with an undercut on the bearing surface.
Pitting/wear marks can often be found on the bearing surface of old auxiliary shafts - replacement is then advisable.
Please check the dimensions of the bearing seats before ordering, as there are different diameters.

FAQ - Bearing needles for auxiliary shaft

21 needles are required for the auxiliary shaft. This item is a single needle - please order accordingly.
Not always. Some early gearboxes were designed for pointed needles. The modern needle type often requires an auxiliary shaft with an undercut. Please check the dimensions in advance.
Old auxiliary shafts often show pitting or worn areas on the bearing surface. This leads to noise, wear and, in extreme cases, consequential damage. With a suitable auxiliary shaft and new needles, the bearing is restored to a clean condition.
