How does the reverser work?
Discussion
I have taken it off so it can be mended, but I am wondering how it works.
I have uploaded some pics here:

So in pic 1, you have:
1- motor
2- Reduction gear?
3- roundy thing that goes round one way
4- circular plate with two round holes in that doesnt go round.
So I guess that the general principle is that bit 3 goes round and the dogs go through the holes in bit 4 to engage with the dogs on the output gear on the engine. If so, what makes it go up and why is bit 4 there?
In pics 2 and 3 you can see that the round plate at the end is a bit knacked. Is that going to be a problem?
Thanks

Put simply, It doesn't.
don't know what the "dogs" are, but in principle the motor turns, the balls poke out through the holes and push against the blocks welded on the sprocket bolt.
Then when you drive forward the balls are pushed back in out of the way.
In my experience the first part happens and the car limps backwards (just) then when you go forwards the balls catch, go "sproing/kerbang" and disappear into the driveway, never to be seen again....
Luckily, I only drive in Hill climb and Sprints where no reverse is required, so it was the first thing to come off the car.

Before you send it to be repaired put it direct to a battery to see if the motor turns if it does it could be a problem elsewhere there is a box under the left hand ( water rad ) side pod that has something to do with the reverse ( Rob will let us know what is does ) i can't remember that will have to back to radical to be repaired, from your photos you will need two ball bearings and there is a funny spring that you will need again from radical.
Then it still won't work just make lots of horrible noises.

Thanks JP. I think I get it! There are no springs or anything, the holes in the plate are just under 16mm dia and the ballbearings just get pushed into the holes as the motor turns. I assume the end plate has to come off to fit the ballbearins (unless they just push through the hole).
I think I need a new endplate as well as the ball bearings as mine is very distorted!

So latest update, Radical do not seem to have any spares for the reverser. I can get the ball bearings, but the end plate is very bent and I don't have any idea what the spring thing looks like.
Anyone got any ideas on this? On advice from Radical, I spoke to EMD who seem to have made some or all of it, but they only have records of supplying the motor, not the gearbox piece.
Thanks
