My McDougleator also uses a steel drive cog, But has a built in slipper clutch.

Some where it talks about them being used as a way to shim the dynamo in and out to get the mesh centralized in the chain with a Miller dynamo. Does that sound right?Hi Gene, I have never seen a PD19 and in fact had to look them up on the Club Shop web site to see what they looked like. Could they be intended for use on a single? I cannot see that they can be used on a twin. The drive system has two holes for the pins in PD17AS so I cannot imagine where a washer/spacer like the Club Shop picture could go. I have seen thin metal plate shims under the dynamo cradle to increase the height of the dynamo on a few bikes. When Dick Sherwin and I were developing the car alternator kit, known as the 'Walkernator' now, I had to spend a lot of time on the drives as this system can produce up to either 30 or 40 amps, depending upon the alternator used and I was worried about whether the original drive system could take it. About eighty are in use and there have been no failures of the drive system that I am aware of. I would not trust a plastic drive sprocket with one of these kits. My worry about the tightness of the mesh with the way that Craig has set his up is that I think that there will be some 'throw' of the triplex chain from its sprocket and I cannot see that there is anywhere for that to go. When I set up one of my systems I always ensure that the dynamo drive sprocket can rock backwards and forwards significantly. No doubt we will hear eventually how Craig gets on with his bike. Sorry but this time I am stumped.
They are used on twins only. See M036. They are used between the dynamo and the case to achieve centralising the gear in the chain.Hi Gene, I have never seen a PD19 and in fact had to look them up on the Club Shop web site to see what they looked like.

Pays to look a little more thoroughly, as I did not see the shim on this page in the spares book. Thanks to the spares company for spelling it out and taking more of my money.View attachment 44987
looks self explanatory to me, maybe not all.
