While mounting the primary drive I found out that the sprockets do not align; the clutch is about 6mm out (or the primary sprocket 6mm in )
This is not a healthy situation for the chain, and I wonder what's the cause.



I remember there was something with a hardened steel washer on the crank shaft?

Hi Hans...There are two types of crankshaft sleeve (that the engine sprocket fits over)...One has a shoulder built in on the rear face as part of the sleeve (the type shown in your photo)
The other type has no shoulder on the back but uses a separate spacer instead, which fits into the recess in the crankcase before the sleeve is fitted...
So, with the 'shouldered' type shown there would be no seperate spacer and you shouldn't have a misalignment problem.....

Are the gearbox mounting plate studs tight?..In other words, is the gearbox 'square' between the plates?...A slight angle here may produce the misalignment you are seeing....Ian

I concur. Check gearbox for squareness first.

Well, I checked with a straight-edge between the front and rear yoke plates and guess: 2.8 mm out of alignment
The rear frame is more out of alignment than I thought.
So back to the galleys

Hi Hans,

Are you sure you have the 3 spacers at the back of gearbox yokeplate in the correct position? They are easily mixed.

Good luck, Michiel

Yes Michiel, everything is in the correct space. But I already had a faint feeling that something was wrong when I mounted the first cross studs; too many hammer blows were needed. Stupid of course, I should have known better

Surely you're not going to strip it all down? Make a spacer for behind the sprocket. I doubt a bent frame would cause that sort of misalignment. You must be bored Hans.
