Re: Wm20 Kickstart Quadrant , Dynamo and Magneto advice/Information

Thanks Ian. While scouring the internet I came across Paul Lindsey and was actually going to give him call, but I think I'll avoid him. Unfortunately there doesn't seem to be many of the old school engineers that specialise in rebuilding mag/dynos up North .

All the information is much appreciated .

Cannot go far wrong with Tony Cooper. sorry I can't remember the number or address, I seem to think it's Halesowen, he did my last K2F mag for my A7 in Oct 2015 and charged me £173 - 90 complete overhaul, really good service.

Kind regards TTJohn

Recommend Tony Cooper. He has done an excellent job on all of mine and my friends my mags.

Re: Wm20 Kickstart Quadrant , Dynamo and Magneto advice/Information

Down here in the South West many of us use Paul Lydford of APL Magneto's. He really knows his stuff,my G3L is running a dynamo from him, and my rigid AJS had a Lucas racing mag done by him. Very reasonable prices too,the racing mag was in poor shape when I gave it to him,came back looking a million dollars and worked a treat to.From memory i think it was approx £200 for the mag,not Vat registered.He also goes to Kempton jumble most times.

Thanks John , I'll check him out also

Thanks Jon , all helpful stuff

Re: Wm20 Kickstart Quadrant , Dynamo and Magneto advice/Information

A kickstart lever that does not return is not a problem with the quadrant, unless the return spring is weak or broken.
It is a problem with the ratchet pinion not releasing and allowing the kick start to swing back.
Usually it is a problem with the gaskets.
The inner one must be a very thin paper one and the outer should also be thin ( about 2 to 3 times the thickness of the inner.
People fit thick outer gaskets to overcome a leak and when you do this the ratchet pinion gets jambed.

So if the kick start moves easily & returns well without being fitted to the box but jambs when bolted up have a close look at the ratchet.

I use Tom and Jeff Magnetos based in the North East. Father and son team. Excellent service and a good price. They do a lot for the Norton owners. Contact them on 07917274099
I have had a quick turnaround every time, bikes not missed a beat.
Also had a three brush dynamo converted to a two brush for my Sloper.
They are my go to repairers.

Re: Wm20 Kickstart Quadrant , Dynamo and Magneto advice/Information

Trevor,
a lot has been written about gaskets in the gear box.
Obviously a very delicate matter.
I used a thin gasket between the housing and middle cover, as you describe. But then when I tightenend the bolts, my gears would't turn around anymore. Fully stuck ! A little thicker gasket solved the problem.

Something else. I had a kick start quadrant and ratchet gear both NOS, but they didn't match very well so I had to use an older gear. That worked fine.

As I said, working on these boxes is very delicate :blush:

Re: Wm20 Kickstart Quadrant , Dynamo and Magneto advice/Information

Don't tell me , tell Dave,
He is the one with the stuck kick start.
The other thing that I should have mentioned but forgot , well to be truthful was not 100% sure about is fitting the rachet & ratchet pinion backwards.
I know you can do it on the unit singles with this result and fairly sure I have done the same on my M20 but not sure now.
I should have kept a diary of all the silly mistakes but after making them once you tend to forget about them.

Re: Wm20 Kickstart Quadrant , Dynamo and Magneto advice/Information

I think that the locking of the gears with a standard gasket (Les told me that they are 7 thou) is more to do with shimming the end float of the shafts correctly, although fitting an over thick gasket or 2-3 standard gaskets can have the same effect. After market gaskets can be far too thick! Ron

Re: Wm20 Kickstart Quadrant , Dynamo and Magneto advice/Information

I suppose you're right Ron.
Forgot to mention that I had some new bronze bushes fitted. It may have caused some difference.

On the other hand, I once rebuild my Triumph 5T box and Norton MK2 box, never had any difficulties.
Never mind. Lets say, it keeps us off the street.

Re: Wm20 Kickstart Quadrant , Dynamo and Magneto advice/Information

Quite so Mick. But the M20 boxes are not as easy to rebuild as some of the others. I once drove one of mine 130 miles to the other side of Dartmoor to watch it being done. There was a lot of assembling, measuring end float through the inspection hole, disassembly and making or altering thrust washers.....repeat....repeat....Definitely not the friendliest boxes I've ever worked on.:confused: Ron

Re: Wm20 Kickstart Quadrant , Dynamo and Magneto advice/Information

Not being conversant with these beasts ,I think I've bitten off more than I can chew by the sounds of it :thinking_face: .

Next question is .....Anyone know of a gearbox specialist that I could send it too to do the job properly for me ,I think it wise I send it to someone that knows what they are doing :grin:

Thanks

Dave
