You can check Rock Auto to get a brand and part number, then go to the manufacturer's site.

Re: fan belt?
A decent way to quick check a belt size is with a piece of string. Mark were they meet and measure it. Works for anything with a belt.

You know, when I'm looking for something old or odd I've noticed that the new young guys up at my NAPA will click over to Rock Auto to find clues.

Re: fan belt?
Or just walk into the local farm supply and get a B-52 belt.
It depends a little on what pulley you have on the generator a low rev high charger generator has a smaller diameter and there is a bigger then normal one to...but usually B-52 fits nicely. Trying to order one on model here would be an adventure...lol |

Re: fan belt?
I believe a 1/2” belt in the 5/8 pulleys would work, but NOT ok. A belt should bite the pulley with the sides of the belt. The belt should not be at the bottom of the pulley, and I think that’s what you would have with a 1/2” belt.

Re: fan belt?
I have my 48 crankshaft pulley off and took a narrow belt, wrapped around it and there is about an 1/8 inch off the bottom of the pulley. I am looking at driving a type ll power steering pump off the front pulley. I cant find a narrow belt pulley for the front or a wide belt pulley for the type ll. Any ideas?

Re: fan belt?
Problem is that a narrower belt can´t handle the same amount of power and not wear out faster.
And you need enought length of the belt to make contact with the pulley. I´ve seen setups where you ad PS and AC on top which makes the belt barely touch the waterpump...not the best solution. Making a custom widebelt pulley for the PS pump is one way of solving it... |
