Hej all
I am restoring/rebuild a model Z from 1934 - from a very poor condition - and need some help.
The bike was fitted with Norton gearbox and clutch,- and when I try to make it back to original shape,- there was some unexpected problems with align from primary and secundary chain.
I have some Douglas 4 speed gearboxes i many pieces ,- but with different kickstarting mechanism
One of them with ordinary tooth sector - another with Bendix starting mechanism
With assemblet gearbox,- the sprocket/chainwheel for both primary and secondary chain was about 10-14 mm out of line with engine and rear wheel (too far-away from gearbox left side)
Can someone please help and explain whats wrong.
Are there made different 4 speed gearboxes for Douglas,- on another of my Douglas four speed gearboxes,- the distance from gearbox to chainwheel is correct and about 12mm less.
I would be grateful for any help and advice
Enclosed some foto of the project
