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.\u003c\/p\u003e\n\u003cp\u003eAnyone 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.\u003c\/p\u003e\n\u003ch3\u003eDetails\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eACP part number:\u003c\/strong\u003e M5523\u003c\/li\u003e\n\u003cli\u003eFor engines or motors mounted on slotted bases\u003c\/li\u003e\n\u003cli\u003eWorks with electric motors and with gas engine drives\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSetting belt tension\u003c\/h3\u003e\n\u003cp\u003eTension 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.\u003c\/p\u003e\n\u003ch3\u003eCheck alignment at the same time\u003c\/h3\u003e\n\u003cp\u003eLay 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.\u003c\/p\u003e\n\u003ch3\u003eRelated parts\u003c\/h3\u003e\n\u003cp\u003eWe also stock compressor motor rails and adapter mounting plates, both sold per pair, along with cast iron V belt sheaves, QD and split taper bushings, electric motors and complete Honda and Kohler gas engines.\u003c\/p\u003e\n\u003ch3\u003eQuestions\u003c\/h3\u003e\n\u003cp\u003eTell us the compressor make and model and whether the base is slotted, and the Warthog Air Compressor Store team will confirm this is the right part before you order.\u003c\/p\u003e\n\u003cp\u003eBelt tightener for air compressor engines and motors with slotted bases, for setting and holding V belt drive tension without a pry bar.\u003c\/p\u003e","brand":"AirComParts","offers":[{"title":"Default Title","offer_id":67721349890323,"sku":"M5523","price":33.49,"currency_code":"USD","in_stock":true}],"url":"https:\/\/aircompressorstore.com\/products\/air-compressor-belt-tightener-slotted-base-engines-motors","provider":"Warthog Air Compressor Store","version":"1.0","type":"link"}
