Re: Primary chain clearance

Forums

Excuse the daft question.....

since buying my Dommie Iâve noticed a few bits missing. Iâve since sourced correct missing parts. First problem I had was the primary cover was Ã?ber loose mostly in part to missing bolts. When I came to refit the primary chain I noticed the new mounting studon the upper case has very little clearance to the chain..... can someone tell me if this is alright?

secondly out of the 3 rear brake hub bolts one of them doesnât look to be wound in and yet feels tight, again this normal?

cheers all

Hi Ross, no such thing as a daft question!

Can't help with the first question as I have the tinplate cover - maybe a photo would help?

On the second one, sounds like you have a crossed thread. Might be salvagable if you can get the bolt out without further damaging the thread, then run a tap down.

Good luck!

My inner primary case is attached to the crank case using slot head slightly raised (shallow domed) screws, not studs with nuts. Is that the issue you are referring to?

Not sure on this, but I believe later rear hubs went to unified threads, earlier were British cycle. Have you tried the "tight" nut on other studs? If tight on all studs will confirm problem is with nut. Maybe you have a miss-matched set?

best regards,

Hello if your having problems with lug fitting then cut them off and re line the tin case up and remark it up and re weld the new set of lugs but shot blast the paint of first get every thing clean a back to bear steel to re mig weld so every thing is in line when you then fit it, do not forget to fit the foot rest tube and the one inside the engine plates yours anna j

Hi Ross

If you are talking about the nut which goes onto the stand-off/support stud (which is attached to the engine plate) centre top ish, then yes the chain does run quite close to this, but has never touched on mine as yet. https://andover-norton.co.uk/en/shop-details/18586/support-stud-inner-chaincase-d12-491-14-6202-

The rear hub sleeve nuts - I would remove them all and compare them side by side, one of them is maybe after-market and longer than the other two, or as mentioned above, one is an incorrect thread form.

And that bottom fixing looks like a bolt screwed in where there should be a stud with a sleeve nut like the upper two.

Hello this at AndoverNorton is for the later dominator early ones are not as long on hex part and the offending nut is in the wrong place it should be a lest an inch lower down as my Norton Manxman650 is , yours anna j
