Looked thru previous threads on the subject of timing belts.
I Found a Mcmaster Carr part number 6484K244 that matches previous specs. (FROM PAST THREADS)
Trapezoidal Tooth Neoprene Timing Belt 3/8" Pitch, Trade Sz 124L, 12.4" Outer Circle, 3/4" W
Just thought I would float this for verification................anyone? When I ask for verification I am asking of the belt pitch and length and width are correct. You would think being italiano the specs would be metric.
We here in the states are getting to the metric system one inch at a time.

Did you try it out? I'm going to need one of those and I buy a ton of stuff from mcmaster.

Mcmaster Carr are stupid enough to not let me browse items without registering on their site.

So, no comment on the belt and although it's unlikely I'd ever buy anything from them, they're now on my black list.

Trapezoidal Tooth Neoprene Timing Belt 3/8" Pitch, Trade Sz 124L, 12.4" Outer Circle, 3/4" W

These trapezoidal-tooth L (Light) belts mate with grooves in timing-belt pulleys. For use in a fully synchronized drive system. Have a 3/8" pitch. Color is black, unless otherwise indicated.

Urethane—These nonmarking belts run cleaner and are more chemical resistant than neoprene.

Neoprene—Run quieter than urethane.

High-Temperature Silicone—Withstand corrosion, chemicals, and temperatures up to 400° F.

Double-Sided Neoprene—Have teeth on both sides of the belt so you can snake them around several pulleys in a multiple-pulley system.

I bought a bunch of belts from my local bearing shop a few
years back... They were all too loose... Waste of time and money.
Call Hermy and get a proper belt.

If Hermy's belts are like the rest of his stock then they're 1980's vintage. I'd rather use a no name belt!

He may well of course have some fresh stock.

Most of my engines have B marked pulleys and Gates belts fit just fine. The original belts were only ever standard items selected and graded and there's nothing to stop you doing your own grading.

Paul, although I respect your opinion and I understand your frustration on not being able to cruise McMaster Carr website without registering, they are my single best source for everything mechanical here in USA. They have an easy to navigate site (once registered I guess) and they have tons of selections of bolts and tools and raw materials for fabrication. They have lots of info on the alloys of the metals involved. Their prices are great and they ship same day or next morning so stuff is on your door in 1-2 days everytime. I have used them for 5 years. They don't care if I am a big company purchaser or a single bolt buyer. So I suggest not jumping to conclusions based on a single relatively minor issue if you are here in US at least. No, I don't work for them.

I used a Gates powergrip part #124L075. Most auto parts stores sell Gates, and even though its considered an industrial belt they can source it for you. I ordered mine through Carquest auto parts in San Diego for under $30. It originally fit a little tight with belt deflection at 4 mm. I think 6 mm was recommended? No complaints after three years running.

I'm not picking on McMaster Carr, I have a blanket policy of not dealing with websites that require me to register before I can access information. To me it's the equivilent of walking into a highstreet store and being stopped by security and being told I can't look at anything in the shop untill I gave them my name and adress. In the case of McMaster Carr I'm told the problem is that they will no longer ship outside the US, so they're not letting you browse until you provide them with contact details. What then happens if you confirm you're outside the US I don't know.

A few years ago the problem was websites with Shockwave presentations for the front page. I sent some really rude emails over that!

That's al least double what I pay for Gates belts. Delivered.

The WEAR LIMIT on the belt is 6mm.

Well I purchase mine in Oz over the internet with RS Online. Their associated company in the US is Allied Electronics.

$5.69 for one, plus shipping. Hard to compete with that.

Just go to their site and search 124L075.

Cheers

Rod, not suffering guilt or paranoia for just buying a standard one.

FWIW, McMaster was fined repeatedly for inadvertently violating export regulations in the past. Because of their huge range of products (over 500,000, I think) and their past willingness to sell to anyone with a credit card, they were force to become rather careful in identifying the actual location of their customers outside the US. Pity for everyone outside the US, as they are a great resource.
