it's that time again.
Anyone have a timing belt exposed to the point where the pitch can be measured?
I'm going to get this done if it means molding them myself!
Actually I'd be surprised if it wasn't something like a 2 or 3 mm pitch.
I'm just looking for someone to do my light work as I'm nowhere near tearing into any of mine.
Just too much going on.


I'm working on other spares as well, stay tuned (sic)

Some detail attached

I have good memories of the Tempo 2020 as well as the Tempo One. Really very good transceivers.

Rubber O rings can be bought to replace the belt.

  A rubber O-ring would be absolutely useless in that application. Look at the pictures; it's a notched belt, otherwise known as a timing belt or a synchronizing belt. It does more than simply transmit torque—the notches in the belt engage the teeth in the pulleys to maintain a timing relationship.

Check Grainger.
They have a lot of cogged belts.
If you can get the length and perhaps some numbers from the original belt...ya might get lucky.
Like I did...

PRB is a mainstay of belts, etc.
