Kick start return spring fitting
Hi,
NH 350cc 1955.
I am nearing the end of rebuilding the GB gearbox fitted to the above machine, all in good condition, just wanted a new bearing to the main shaft at the kick start mechanism end.
I am now at the point of fitting the kick start return spring, knowing that the inner spring anchor, the bent bit in the middle of the spring, fits to the gear box middle case via the kick start quadrant and the outer spring anchor, the bent bit at the outside of the spring, fits to the gear box outer case, all whilst having to hold the spring in tension I am expecting to lose both temper and fingers. Plus, if the spring tension is not correct I will have to repeat this all over again, my fault, I did not record the inner spring anchor position to the kick start quadrant at strip down.
Please, is there an easy way of fitting the spring ??????
My own thoughts on a solution is to anchor the outer spring anchor to the kick start quadrant "stop boss", the lump of metal in the middle case, by drilling and tapping a hole in the "stop boss" and using a screw as the anchor point. The spring could then be fitted in its entirety to the middle case prior to fitting the outer case. I'm sure I am not the first person to think of this, as it been done before, is it feasible, have I missed something.
Your advice and help would be very much appreciated.
Regards
John Palmer.

Fit the kick starter on the spline and wind up the tension then fit everything onto the gearbox, even the gear lever is left attached to the outer cover. Don't forget the bit the leaver inside pushes against to release the clutch, don't ask me how I know If you don't live too far from me I'd give you a hand,
Good luck. Steve

Re: Kick start return spring fitting
Hello John,
First you fit the kickstart assembly to the case, I found that the position of the inner tag on the 'teeth' does not really matter.
Wind up the spring by turning the kickstarter until you think it's enough.
Then fit a longer screw in the upper hole of the clutch arm adjusting cap like on the picture, this prevents the kickstarter from unwinding.
Now you have your hands free for doing other things (drink coffee, put up new year centrefolds, etc)
While fitting the outer case to the inner case you have to wiggle a bit to get the teeth to line up, the teeth hang down and the half round gap on the left hand side fits against the round aluminium boss on the inner case.
If you have the box in a vice you can look from all sides in between the cases to see what your'e doing, on the bike it's a bit more difficult to get a good look.
After doing up all casescrews you can readjust the position of the kickstartlever on it's shaft to the angle you want it to have on the bike.

Re: Kick start return spring fitting
Thanks Rob for your offer but I followed Vincents method and with a bit of wiggling I got the spring fitted OK, all fingers intact.
Afterwards out of curiosity rather than need and just for the sake of one small tapped hole I fitted it in its entirety to the middle case, this also worked OK. The spring was very easy to fit in that you can see everything you are doing and also you can ensure that the spring stays concentric to the quadrant spindle as it is wound up into tension.

John Palmer
