[andy_con]

does anyone know the exact spec of the spindle/powered draw bar pulleys?

the belt has 18 teeth

belt reads

150 l
k9

gap between teeth on belt is about 5mm

im pretty sure the pitch is 5mm just wanted to check

L is an older imperial pulley/belt tooth size.
150 refers to the belt length. IIRC the older imperial sizing is in length, so 150 meaning the belt is 15" long. (metric belts are typically measured by number of teeth).

The only thing you need to physically measure is the belt/pulley width, but going by the above picture, I'd guess it's an inch wide belt.

I thought I had a note for the pulley sizes, as I upgraded my spindle motor to a servo, but I can't find the notes or the invoice for the new pulley and belt.

Thanks for the response!

I ended up machining a sleeve to use the original pulley, now have a treadmill motor setup installed with a custom mount
