Douglas flywheel
« on: 16 Dec 2017 at 06:50 »
Hi

Does anyone know if or what model Douglas these flywheels are from.
They came in a box full of mostly 2 3/4 parts. Obviously they don't suit a 2 3/4.

Thanks
Brett

Brett,

Don't know what they are from, but definitely not any model Douglas ever made.

P.S. Any relation to Wade camshaft family?

Thanks Doug

I didn't think it was off a Douglas bike.

No relation to Wade Camshafts that I'm aware of.

cheers
Brett

Numbers cast into both flywheels are "150 20 D", one side has an "A" the other has a "B"
The distance from crank centres to the conrod pin is 2.0"

It doesn't appear to be for a twin, more likely a big single, possibly BSA WDM20????

Thanks for the heads up..
I will look further into the flywheel numbers.

Sorry, no Indian parts in this box of bits.

cheers
