pvisseriii said:What is the size that came with your kit. It is printed right on it, 10/xxx. Where as the xxx will be 890, 920 960 etc. And was this size requested or just a standard.
My thinking is that the 920 is standard and I got a 890. Too short.
Thank you HOBOT (how do you pronounce that),hobot said:920 tooth count lenght is the expected and accepted size for Norton Commandos.
Other special order sizes may work but will put gearbox at either end
of its adjustment range.

I think that is a Steve Maney kit belt.highdesert said:I just got a new belt from Phil at Fair Spares, $94.
Why on earth would I want another 890. Please try to keep up Hoby.hobot said:I missed ordered a belt so have an uninstalled
red 328 Synchroflex EX Gen III 30mm AT10 / 890 length for Commando's.
Waldrige supplied it.
Make cheap offer with shipping to take it away.

pvisseriii said:Roger from RGM reports that the 890mm belt is the standard size for the 750 Norton. Along with the 28t driver and the 55t driven hubs which is the kit I received. He also asked for a picture of the through bolt and showing its position in relationship to the adjusting slot on the gearbox cradle.
No responce. I guess I am at a loss.
Are you confused or are you trying to confuse?hobot said:duh, pvisseriii - 28T drive and 55T driven pulleys sound like intended
for a small scooter not a big bad Commando.
Of course a AT!0 style has less teeth, more belt space.
My Kenny Deer-[Haywood?] 30 mm belt drive has 36T and 72T,
so 920T size belt gives mid slot adjustment. But this is
not AT10 style belt, forget the code off hand.

pvisseriii said:I purchased a 920 belt from a local power tranmission distributor and went to put it on. Got everything loosened up, slipped on the belt and ran the adjuster all the way to its end point. "No freaken way" loose a a goose. I undid the adjusters screws all the way off and ran the gearbox all the way to the other side and found much more slackability. I dont know how, it was just there. I put the 890 back on and had all the adjustment in the world. All is good. I will copy this to Roger at RGM.
To all of you, sorry for the mislead. 890 is confirmed.
