Torque converter belt

[gcraver7]

I’m building a racing lawnmower and I need to mount my torque converter a certain way. I need a belt that will stretch approximately 16in from the centers of both pulleys and about 22in from the outsides of both pulleys. It is a 40 series

What size driven do you have?

What size driven do you have?

6” driven

Does 40 series have a 6” driven?
Or is it a 30 series with 6” driven?

40 series with 7-1/2” driven and 16” OC requires a belt that is 48-1/2” outer circumference, 7/8” top width. I believe the belt is symmetrical with 15degree angles on both sides.

Not sure if 40 series Belts are same angle ( V ) as a standard belt? Maybe need 30 degree belt? I think 40 degree is standard.

What is that brand of belt again?

I didn’t give a Comet part number because I couldn’t quickly find a Comet belt for 40 series with 16” center to center spacing.

Also unable to quickly find a 30 degree Kevlar V belt with 7/8” top width and 48.5” outer circumference.

I might have sent OP on a wild deuce chase?
