I wish to buy a replacement belt to have on hand for my evaporative cooler blower. The outside measurement of the current belt is 59.5" However, it is several years old and probably stretched. The manual doesn't give a replacement belt size.
I checked the length of an unused V-belt marked 52" The inside measurement is 51", the outside 53". So a V-belt marked measurement is an average?
So what marked-size belt should I get for my replacement? Maybe 59"? 58"?
57"? The belt tension has a limited amount of adjustment by moving the motor bracket. I don't know what sizes belts come in. I looked in Wal- Mart yesterday to get some idea but evidently they don't carry v-belts. I'll probably have to buy one in Lowes.
