Thread: v belts

    v belts

    Large air handler belts keep turning over on pully sheives? The more or less tension I put on them does not matter. Please offer suggor pro advice.

    Belt is probably loose side to side, and miss aligned. Correct the alignment first. The miss-alignment is waring the sides of the belt - making it too narrow. Depending how long its been that way, the sheaves / pulleys are probably worn as well, and may have to be replaced. OR you are running the wrong belt.

    get rid of adjustable and use banded belts with new sheaves, they work great with shock loads.

    Too much belt is riding outside of the sheave will cause this. You may need to open the pulley or change to a larger diameter.

    Use a straight edge or string for alignment.

    Put the right sized V-belt on it

    What belts are you using and whats the sheave model number.

    Sheave or pulley is really worn or you have the wrong type of belt... Like a A belt when you should have a B belt.

    Check wear on sheaves. Replace if worn. Alignment is critical on many units. After 25 years of using a straight edge or string, I have been using a laser sheave alignment tool and it is so easy and accurate.
