Sounds like Microsoft onenote, it's free too even on Apple. I hadn't thought of doing that though, thanks

I think that may be the best way to go AQM. That said, there is a local chain specialist who says he will have a look at my M3W with a view to a chain conversion, if a durable belt drive proves just too difficult. The chain drives generally seem to have steel drive gears and alloy sprockets with no big wear problems and changing ratios is easier. A guard would help reduce wear from grit contamination greatly, it gets pretty dirty back there even with a mudguard fitted.

Bought my M3W last December with over 14k on the clock. Now has over 15k on the clock. Full Morgan agent service history and complete with all invoices. Bought from a Morgan agent. No record of the rear drive sprocket being replaced. There is quite a lot of belt noise from the drive but I have not had an opportunity to listen to another M3W for comparison; could the sprocket be the cause? Next service due late summer 2015 if I put on the planned mileage over the next few months; touring Eire late April and visiting the outlaws in summer. I'll now get the back end up and inspect the sprocket. Is 15k a record?

Welcome to TM, AMC. And 15,000 miles up, too! Not sure who's up in that region, there are a few with 10k plus that I know of.

If you can master the black art of posting pics on here, stick some up of your car as someone may recognise it..

Yes, very similar. horses for courses as they say !

Or have a shaft like the ACE

So i have spent alot of the past few days researching Chain systems. With the help of Dave G's guidance and contributions from others I hope to get a chain system up and running on my 3W soon. It should be an interesting project.

Keeping the same gearing rations and bevel box.


I cannot see any possibility for a derailleur because this requires a chain with lateral flexibility. This is why bicycle chains break so easily. On the subject of lateral flexibility, one of my first checks before i get cracking in earnest is to check the amount of torque effect on the bevel box. If it twists too much then a chain system will be harder to implement.

I hope to make it possible to replace the toothed part of the sprocket which will also enable ratio flexibility a la nippymog's suggestion 17/03/15 10:02 AM.

will investigate automatic oilers later as they seem to be easy to retrofit.

enclosed chain guard seems sensible. Need to investigate space and mounting options

If you have any metallurgy experience and can give me PM'd advice on steel grade, anodizing and hardening specifications that would be appreciated. There is of course lots of information on this from manufacturers, but they all seem to do it differently.

You were joking about the dérailleur weren't you Charles? Or are you planning to lighten it by removing the gearbox?

If you ran a twin sprocket on the BB you would then have a twin speed axle, 10 forward gears and 2 reverse!

Thats just silly.

I agree.



Who needs reverse?
