Kickstart return spring screw
« on: 29.05. 2010 18:52 »
Dear all,
The gearbox rebuild progresses slowly, every step a challenge...!!
The latest is I'm looking at the little screw that holds the kickstart spring in place. When I took it out the end was chewed & some alloy swarf came with it..  I cut the end with the b*gg*r*d threads off and have carefully wound it back in. It goes in until the end is just flush with the outer case & stops. A fresh 1/4BSF 26TPI bolt does the same.
I was hoping to maybe put a longer screw in with a nut on the outside..

Question - is this supposed to happen?  The parts list doesn't show a nut but at present the screw doesn't go in far enough to hold the spring tightly..

All thoughts appreciated.
thanks,

Adrian

Adrian,

there's a shouldered nut fitted to that screw on the outer cover, no. 69 on the drawing below (part number 27-4401).

Cheers, Markus

Thanks Markus,
I guess the outer threads must be a little crimped so I'll gently force the screw through & get one of the proper nuts.. Looks like I need a better parts list !!! (have saved a copy of the one you posted - many thanks..)

All the best,

Adrian

Adrian,

I "borrowed" the one I posted from Draganfly.
http://draganfly.co.uk/

Their site is a very good source of information with many drawings and original part numbers.
