Norton Gearbox Lower Stud Assembly

Gearbox and lower stud replacement assembly.  Permits removal of the gearbox without the need to disturb the engine.

This would not be possible with the normal arrangement, because the stud cannot be withdrawn, because of the proximity of the lower frame tubes.  Dimensions should allow the bike to be built with the original steel engine plates, or with thicker allow plates.

Choose the correct fitment for either standard steel or thicker alloy engine plates.
