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.

Re: RGM belts

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.

Thank you HOBOT (how do you pronounce that),
I was afraid of that. Maybe Roger at RGM will take care of me. I know I can get one locally but it is a little pricey.

Re: RGM belts

Aw shoot, just trying to send my AT10 red belt to a good home
not that you should run it. You can't judge its fit unless you know
the pulley sizes.

Actually I miss ordered a hand full of 920 HD 30 mm belts
before I realized not strong enough for new Peel power.
One belt. the last being run, has a slice in it that lets light an air
though from crank nut going under it, or maybe it was
the clutch nut. Got Deer sold belt drive I'll not be using
any more either.

For greater strength you might consider converting the Commando to a chain drive. Oh that's right, they CAME that way! :)


Sorry, couldn't resist....;)

Re: RGM belts

Actually Mike that is plan B if 40 mm belt can't resist breaking big tire
traction loose or gearbox metal apart.
It'd be a bugger to seal back of primary case with the out rigger mount
huge cut out. But already done it once - sealing huge hole for set
in place dry belt drive with out rigger, as I do water crossings and Grit
blasting paths routinely. Sealing 1' case for movable gear box will
test my creativity if it comes to that.

Re: RGM belts

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.

I also sent him a photo of the center of the clutch at its forward position which is yet not enough to bring the belt to proper adjustment.

No response? When you send the pictures?

And I have to steal that primary cover hole design. That's sweet!

Re: RGM belts

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.

Are you confused or are you trying to confuse?

In this case I am the one confused why there is a belt fit issue.
Must not be a belt drive type I'm familiar with, sorry.

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.

Are those sealed bearings in the clutch hub? I hadn't thought about that as an upgrade to the standard hub.

They are sealed so you can run dry. Obviously.

Full RGM belt install coming up...
