Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 High grade of steel specialy made rear sprocket

My Super Max wheel has the number "65" molded on it and I have yet to detect any difference in speed. The speedometer, like the fuel gauge, still lie. They are in cahoots. Go with what they have. My dealer has offered on numerous occasions to adjust the speedometer to reflect reality and I have refused. It is not important to me. What's behind me is not important, either.

The mass repartition of the lightweight steel sprocket has been done to be quite the same of the aluminium sprocket. The main problem you can have with a heavier sprocket is not a problem of acceleration or "power" the engine has a great torque it's a problem of suspension. In fact with an heavier sprocket you increase the non suspended weight and in some case the suspension have some difficulties to work.
And the last question is why travel 3kg (6.6lb - 212 oz) more? You know how many beer it is?

I decided to go the SuperMax route in the end and have just received the modified sprocket.









The weight of the modified item is 2.02Kg (4 lb 7 1/8oz) compared to 2.82Kg (6 lb 3 3/8oz) before modification.

The costs added up like this:
Shipping of 'spare' alloy pulley to me from a friendly TMer: £20
Shipping to Supermax: £36.43
Supermax Process: ($535) £347.51
Return shipping: ($70) £45.47
Total: £449.41 GBP

I'm looking forward to fitting it in a few weeks' time when some other issues have been taken care of!

nice, but where is the second flange gone?

Gone the way of all flesh. Don't need it. I have the Super Max installed and the belt tracks beautifully and stays put. It barely hits the flange and rides without overhanging the teeth. This is with the original fixed bevel box.

How long did it take?

Looks like I will have to go this route over the winter as my alloy pulley is now louder than everything else put together.

Well SORNED it yesterday and ripped it to bits today for the big winter clean and service.

Rear pulley off so it can be shipped to Supermax in the near future.

7500 miles and the teeth are almost 50% worn out.

Agreed, pretty worn. A new pulley will work wonders. I bet the belt still looks like new.

Sure is, it's like new.

Quicker than I was expecting - I had it back around 2 1/2 weeks from sending.
It's now fitted. Just have to re-check the belt tension as I think it may still be a tad tight.
