Multiple grooved pulleys....Manufacturers??? 1

[tmox]

I am in the process of creating a test rig that involves an alternator and a motor. The rig is driven by an 8 ribbed multi-vee belt (serpentine) the same kind that is on every car in North America.
The drive pulley is in the 8" range and will be held on the drive shaft with a taper lock hub.
Why, why, why can't i find a manufacturer for the pulley in North America?? I did manage to find one manufacturer with what i want......but, they are in Austrailia.
Surely, (as these are on every car) I don't have to have a custom pulley made. I have been searching online for hours and hours.
Can anyone point me toward a N.A. manufacturer??

If they're on every car in America and it's a one-off for a test rig; wouldn't it be easier to go to a local car breaker and get a good second hand one, even if you had to get a machine shop to bore it out to fit the shaft/taper lock?

The type of pulley you are looking for is a belt developed for the automotive market so it will not show up as an industrial off shelf product. You may find some in the custom/race car world otherwise any competent machine shop can machine one.

What not just go to a car spares shop?

Optibelt manufactures these types of pulleys both for the automotive and the industrial market.

Great. Glad to be able to help you

The automotive pitch is different than the industrial pitch of J, L & M sizes. The aotomotive pitch is K. It may be easier to switch to the industrial pitch for a wide assortment of "off the shelf" pullies from either Gates, EPT, or Carlisle PT products. I think Ametric may offer the K pitch pullies.

vims,

Timing belts are shaped like the one on the Optibelt site (grooves perpendicular to the belt axis), however, automotive serpentine belts (especially ones connected to the alternator) have the grooves running longitudinally.

Look around more on the optibelt website and you will find these types of pulleys, multi v or poly v, with the grooves running longitudinally. I have bought these types of pulleys and belts from optibelt just a year ago.

The Optibelt catalog DOES NOT show the pullies for "K" pitch belts, only for J, L, & M ppitch industrial type belts. You are still better off changing BOTH pullies to the industrial type, as I do not know of any suppliers of standard automotive pitch pullies. It would be wiser and cheaper to change to industrial style, instead of getting a custom pulley fabricated. These can be bought through Gates, EPT, Carlisle, Ametric, Optibelt, and Maurey. Best availability will probably be Gates or EPT.

Diskullman:
You are correct about the K pitch. I checked, and it turns out I bought the belt from Optibelt, but the pulley from another supplier, Jens S.

. Don´t think Jens S has any sales rep. in US, though. Strange by Optibelt to sell belts with the K pitch to the industrial market, but not pulleys. I agree with you diskullman that it would be a good option to switch over from the k pitch to a more common industrial type.
