SWENCH---HOW DO YOU USE ???

Okay, what is a "swench"?

Would you mind posting the link to the ebay page or item number so I can see what a "swench" looks like?

Maybe you could even post a picture here.

Thanks!

Thanks!

Easiest way to tell which way to turn it is...

Chuck one of the square drives in a vise, attempt to turn it one way and then the other. One way you will feel that you are pulling againist a spring, that is always the direction you should pull the handle to apply impact or torque. Mark both sides of the head with arrows so that you know that is the direction to pull, always againist the spring.

The other way, all you get is the "click.. click.. click.." of the ratchet mechanism and little or no resistance.

Put a socket on it and find something to loosen, a tractor lugnut, etc. put the socket and ratchet on the nut, and pull in a CCW direction againist the spring (oops.. wrong side?? try again on the other side.. ah ha) anyhow, you pull againist the spring for about 30 degrees of rotation and suddenly the device inside trips a pawl and WHAM!!! If you have enough room to keep pulling, do so, if not, push the handle back the other way till the ratchet clicks, and then pull again.. WHAM!!

In the end of the handle is an allen screw head and a scale kinda like a torque wrench on the side of the handle. The numbers are generic, merely reference, they do not equate to a specific torque. You can vary the impact force by adjusting this.

The model number tells you the size of the square drive. a Model 500 is 1/2", a 750 is 3/4", and a 1000 is a 1" square drive. Oddly, there is a Swentch on Ebay right now, its a model 625, thats a 5/8" square drive!!! I've never seen a 5/8" drive socket, but oddly, I bought some 3/4 drive sockets not long back and included was a 5/8 female to 1/2 male square drive adapter. I deemed it useless and put it in the back corner of a tool box drawer.

Hope this helps. Its a very unique tool.

If the thing appears frozen, on your model 1000, remove the four bolts around the base of the handle and the cover will slip off to reveal some of the mechanism. Its safe, the spring is in the handle, nothing will go flying away on you.

The Swench is and was made by Curtis Wright Aeronautical Corp, They still sell them, mostly to the government and to oil rigs and the like. They seem to hit differently than a powered impact and will break loose stuff that an equavalent air powered impact won't touch.

The Curtis Wright website has a little about them.

They are very expensive new. The ones on Ebay are usually old, having an address with the old postal zone numbers, which went out of use about 1962.

They are true impacts and you should use impact sockets on them, or you might break the regular sockets.
