Air Compressor Belt Tightener for Engines and Motors with Slotted Bases
A belt tightener for air compressor engines or motors mounted on a slotted base. It gives you a screw to push against instead of a pry bar, so the motor moves back in a controlled, square way while you set belt tension, and stays put while you tighten the hold down bolts.
Anyone who has tensioned a 10 HP compressor single handed knows why this part exists. Levering a motor back with a bar means the motor cocks in the slots, the sheaves go out of alignment, and the tension you thought you set changes the moment you let go of the bar.
Details
- ACP part number: M5523
- For engines or motors mounted on slotted bases
- Works with electric motors and with gas engine drives
Setting belt tension
Tension the drive until the belt deflects about 1/64 in per inch of span under moderate thumb pressure at the midpoint of the longest unsupported run. Too loose and the belts slip, glaze and burn, and on a compressor that often shows up as a machine that will not make pressure. Too tight and you are loading the pump and motor bearings, which is the quieter and more expensive failure. New belts stretch, so re-check tension after the first few hours of running.
Check alignment at the same time
Lay a straight edge across the faces of both sheaves before you lock the base down. They should contact at four points with no gap. A drive that is tensioned correctly but misaligned will still throw belts and chew up the sheave grooves.
