Anyone got a sidevalve ring-gear for the flywheel?

[RobThomas]

As it says, I'm after a new set of teeth for one of the engines. Has anyone got one or even a very good flywheel?
I'm in Cardiff, if that helps.

Cheers

Sorry, can't help. Try MMOC Spares, it is listed under engine spares.
You need a 102T ring gear, make sure that you do not get a flywheel with an 80T ring gear off a WD generator engine or possibly a Morris 8

Rob,

When I rebuilt the engine in my MM I replaced the ring gear with new . I found one on Ebay for very little money. The old ring gear worked fine but was a bit worn. You can have it for the cost of shipping. I did find a source in NewZeland but it was VERY expensive.

Hi Rob, I probably have a flywheel here somewhere, I seem to have most of the heavy parts, but there's no hope of mailing it from Canada

Here's a suggestion that will work unless the old one has actually broken. Use an acetylene "wrench" to heat the ring gear enough that it will come off but instead of removing it just rotate it ninety degrees on the flywheel and let it cool again.

You will now have nice fresh, hardly worn teeth right where the starter engages and once moving the fully engaged pinion will go past the worn teeth without slipping. This works because a 4 cylinder engine always comes to rest in one of two places and the initial starter engagement causes the worst wear. I HAVE DONE THIS ... fifty years ago, but I can assure you it works prefectly, I would do it again in a heartbeat if I had that problem.

Aaaaaaaaaaaaaaaaaaaaaaaah! This one has already had that done, by the looks of it. Hardly a tooth left on it. It might even have had the wrong starter unit in it since the teeth are so knackered.

Thanks for the tip, though.

Thats a pretty good offer!

I was just about to mention the 90 degrees option - the one's I've seen are only work in 2 places (180 degrees apart) and with the bolt spacing for MM flywheel you can't relocate the flywheel 90 degrees on the crank.

I did wonder if it would help to reverse the ring gear as well as turning it 90 degrees - maybe someone can blow a hole in that theory but it seems sensible to me.

I hadn't noticed the reply from Mmaurice until just now. Thanks for the offer! I may take you up on that if nothing NOS shows up. The starter tooth pattern might also be an issue so I'll look into that, too.

You cannot reverse the ring gear because the teeth are profiled.
