Q:How to know the size of a belt having a 1-1/2in x 4-1/8in pullies
by|Aug 16, 2021
1 Answer
Answer This Question

A:  The belt size is specified by the manufacturer of the cooler. If that is not known there is a formula to determine belt length. The formula is: L = 2C + 1.57(D+d) + ((D-d)²)/4C. Where L is the length of the belt, C is the center distance between the two pulleys, D is the diameter of the larger pulley and d is the diameter of the small pulley. There are also calculators online that can be used.

      A:  Pulley size should match up with motor. This pulley is for a 3/4 HP motor and might work with a 1/2.

        Hot air furnace fan pully
        This is a great replacement adjustable diameter pully. I used it as a replacement on a hot air furnace. The price is great and cheaper than a fixed diameter pully at the local hardware store.
