8 Tooth sprocket ?
« on: March 30, 2018, 03:31:27 AM »
Any clues ? ........

Ive got an 8 Tooth sprocket Im wondering what it comes off

it has a taper from 1/2" to .450"  , fits splitdorf shaft so 6 degree
its 3/8 wide
tip to tip 1-1/2" across
has a key 3/32 wide
my guess 1/2 centre to centre chain

most american magnetos are gear drive and generators are belt and pulley .
maybe this is AJS , Matchless ?

cheers

Some Miller and Lucas generators  have mag std tapers ,a small keyed sprocket is more likely from a generator.......If it is Splitdorf,it may be from a generator drive....Indians had chain drive generators,driven from the clutch drum by a gear and chain.

Yeah,most Indians were belt,what about the WD Indian 500s?   Some Panthers had chain drive generators....Ive got a couple ,but all the drives were missing when I got them.....The Villiers motors also generally used a chain drive genny pre war...The smallest mag sprocket Ive seen would be JAP with 10T.
