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:

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
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:
