{"product_id":"bullwhip-idler-throttle-control-gas-air-compressor","title":"Bullwhip Idler Throttle Control for Gas Air Compressors - 24, 36 and 60 in, Small or Large Cylinder","description":"\u003cp\u003eThe bullwhip is the throttle control on an engine-driven air compressor: the cylinder and cable that pull the engine down to idle when the tank reaches cut-out pressure, and let it back up to speed when pressure drops to cut-in. It is why a gas compressor on a service truck runs all day without the engine stopping and restarting against a loaded pump every few minutes.\u003c\/p\u003e\n\u003cp\u003eIt is also a wear item. The cable stretches, the cylinder seals dry out, and the first symptom is usually an engine that will not come back off idle quickly, or will not drop to idle at all and sits screaming at full throttle against a closed unloader. Either of those is a bullwhip, not an engine problem.\u003c\/p\u003e\n\u003ch3\u003eSizes\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eM5543, type S-24:\u003c\/strong\u003e small cylinder, 24 in, fits 5 to 6 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM5541, type S-36:\u003c\/strong\u003e small cylinder, 36 in, fits 5 to 6 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM5546, type S-60:\u003c\/strong\u003e small cylinder, 60 in, fits 5 to 6 HP\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM5542, type L-24:\u003c\/strong\u003e large cylinder, 24 in, fits 8 HP and up\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM5540, type L-36:\u003c\/strong\u003e large cylinder, 36 in, fits 8 HP and up\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eM5547, type L-60:\u003c\/strong\u003e large cylinder, 60 in, fits 8 HP and up\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eChoosing cylinder size and length\u003c\/h3\u003e\n\u003cp\u003eTwo decisions, and they are independent. \u003cstrong\u003eCylinder size\u003c\/strong\u003e follows engine horsepower: small cylinder for 5 to 6 HP engines, large cylinder for 8 HP and up. A bigger engine has a heavier throttle return spring, and a small cylinder will not reliably pull it down. \u003cstrong\u003eLength\u003c\/strong\u003e follows the geometry of your machine, the run from where the control air is picked up to where the cable reaches the throttle lever. Measure the route your existing cable takes, with the bends, rather than the straight-line distance. If you are between sizes, go longer: a cable with a gentle extra loop works, a cable pulled tight around a corner binds and will not return.\u003c\/p\u003e\n\u003ch3\u003eReplacing one\u003c\/h3\u003e\n\u003cp\u003eNote how the existing cable is routed and clamped before you pull it off, and reproduce it. A bullwhip that rubs on a hot exhaust or chafes against a belt guard will fail again quickly. Check the control air line and the pilot valve at the same time, because a slow or sticky signal looks exactly like a tired bullwhip.\u003c\/p\u003e\n\u003ch3\u003eRelated parts\u003c\/h3\u003e\n\u003cp\u003eThe bullwhip works with the engine idler assembly, which is matched to your specific engine, and we stock those for the Honda GX390, GX620 and GX630 and for Kohler K Series, Magnum, Command and CH440ST.
