SOURCE: I have a husky impact wrench, set at 100psi, but

There should be an air control valve adjacent to the air inlet, is it opened sufficiently. Failing that there is a problem with the drive motor. It could be seized bearing or a broken vane. There is nothing you can really be doing wrong, it is a very straightforward tool.

Impact turns but no tork why

An impact wrench works by directing air into a chamber where a hub with sliding vanes turns to do your work for you. If any of the five or six vanes are damaged the tork value will go down. It is possible for the hub to turn freely however the more air that gets past the vanes, instead of pushing on them, the lower your tork value will be. The bearings for the hub could be damaged or seized but that usually affects free spinning speed more than tork. The insides of an impact wrench are fairly simple, take it apart and check the vanes and bearings. Ingersol Rand makes rebuild kits for most of their impact wrenches.

My CP impact wrench run fine when not removing a bolt. When removing the bolt it turns it a few rounds then stops

Try a good cleaning with diesel fuel. Keep adding diesel into air inlet until the fuel comes out clean (add diesel then connect air to blow it out) . Once clean, add several drops of oil and retest. If it works better but not full power, try another cleaning with wd40 and retest. Good luck

My CP 734 has no power under load. Is there a rebuild kit to fix this problem and where can I get it? If a kit is available, is that a difficult rebuild? Tim

I used to repair these impacts for a living. Simplest first thing to do is back off the three 1/8" set screws in the back a couple turns. Pour a little varsol into the air inlet and plug it in. run the gun until your hand is black, (wear a glove). Once the varsol stops disconnect the air, add a few drops of air tool oil and tighten the screws slowly and evenly. You will hear the impact rpm increase. If your gun doesn't speed up to it's original scream you will have to remove the four 5/32" set screws and see what's worn. To open it hold the impact by the nose 3" off the table and position a center punch in the hole of the anvil shank with the same hand and hit it with a hammer hard enough to overtake the spring. The guts should drop on to the table in tact. The guts are in twp parts, the hammering mechanism, and the air motor. The three 1/8" screws hold the motor together. You will soon see the problem. Take the back off the air motor and it will show your if the veins are worn. Cjeck the end plates for wear. You can turn the end plates down on a lathe if available. As a rule of thumb, if the anvil shank is dry buy a repair kit, if it's wet, buy a tune-up kit. If the ring on the anvil shank doesn't turn, buy a repair kit and change your sockets. When rebuilding these front seal often leaks. These impacts are supposed to use 30 weight oil, but a mix of Ingersol Rand grease and 30 weight oil, ( just till it's slightly runny) will stay much longer. Assembling the anvil assembly can be tricky until you figure out how to hold the shank and two pins with the same hand. Good luck.

Air Wrench Question

An impact wrench works in the manner suggested by the name of the tool: through the principle of impact. In order to understand how an electrical or air-powered impact wrench works, it helps to know first how a manually powered impact wrench operates. A manually powered impact wrench looks like a fat screwdriver; on the end where the screwdriver blade normally goes, you can snap on screwdriver bits or sockets.
