Does it turn clock wise or anti clock wise ?

Re: Triumph speedo drive wanted !

They all must turn clockwise as you look at the cable slot. The Triumph speedo drive is on the right therefore if you hold the drive in the correct orientation, turn the driven shaft towards you (clockwise) to give the correct clockwise output. Ron

There is usually a few of them on ebay, but the sellers usually don't say whether they fit left or right side, so best to message them to find out, the 3HW fits on the right hand side/offside, the pinnion/shaft will then turn anti clock wise when the bike is going forwards, and output drive to the speedo clock wise.

The small pinnion you you need is a 18 or 19 tooth for 19 inch dia wheel, these are very hard to find now usually find them at jumbles.

Peter Long at Cornucopia has Triumph speedo drive gears the large one and small ones for 19"-20" Wheels. Ron

Ron,
I have a speedo drive here. If I hold it in the "M20 position" it turns anti clockwise.
Where could it be from, any idea ?
Maybe Matchless or Norton rigid frame rear wheel..?

Re: Triumph speedo drive wanted !

Michel if you mean the M20 type hub driven speedo drive. Yes nearly every one you pick up at a jumble is like that, as you say it fits on the rear wheel on the right. Ron
