Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 rear pulley

As I needed a rear pulley very quickly, because of premature wear, almost (10000km) I decided to buy the first one that was almost identical to the ratio level, it is 2' wide and 65 teeth, it my necessary to modify and change the inner diameter with an offset inside the expander 3 mm which acts as a centering bore for the new brand BDL this pulley, the pulley is a central thickness of 5/8' instead of 3/4' approximately, therefore j did it as a flange that the screws is identical.






I hope it shines especially for its longevity.

Good job

especially for the price.

It adds only 5 km h to over 5,000 rpm in fifth gear, especially puts money in the pocket.

Hi

What material is this made from ?
I am guessing aluminium ?

Thanks

the pulley is aluminum with steel side panels set, I did not think to test for hardness of aluminum pulley with original, I would be tempted in a fabricated steel with a Thermo treatment, puts it is a lot of work for me.

I agree steel would be preferred however it will be interesting to see how long this aluminium one lasts.

Anyone thought of titanium? Seems to be the "replacement material of choice" for top end bike owners.

Hard, light, doesn't corrode. But expensive and needs special skills to machine.

a pulley mounted steel with aluminum hub would be more than enough see sheet metal stamped without machining, it is recommended not to clean titanium with trichlorethylene because it creates a surface that can corrosion creates primers cracks in the duration of time, the Pinion of bevelbox 32 steel tooth do not wear, so with 66 tooth should be everlasting, mounting the steel pulley should be like for pulley plastic. http://www.supermax.net/Pages/home.asp

I just forwarded this site to my dealer. He acquired a new rear pulley for when I show up again as the noise and chirping has picked up and I can feel the wear on the teeth already. He had sent it off to the platers in anticipation so they could anodize it even more. It is still only aluminum, however. The belts, being made of Kevlar or carbon fiber, are just as tough as steel and should last well over 100,000 miles if set up properly. I think they'll eat the aluminum once again. I don't know why I have been blessed with the ability to demolish the rear pulley but I have. The forward pulley attached to the bevel box is made of that same tough steel that drill bits are made of and shows absolutely zero sign of wear!
