Pulley lengths - Stock Alt & WP
 

Hi guys,

I don't feel the need to change my pullies and am wondering if anyone knows the non airpump size for a belt with the stock pullies.

As I am well aware you guys will tell me to measure with a string which I have done and it gives me a 29.5 can anyone else confirm this?

I thank you guys in advance for the help

You need a 300mm belt http://www.robrobinette.com/air_pump.htm

How in the world can it be a 300mm belt. According to my calculations 300mm is a little over 10 inches!

it can't be 300mm, even the shortest 5 rib belt we carry which is approx 28" = 710mm

So I am not crazy. Thank you sir.

Looks like they got the belt part number mixed up with the length. You'll be looking for a 30" belt. IMO, you should do a pulley kit to make sure you have good contact with the waterpump pulley.
