The Gray Chain 3570 AIR offers the ultimate in simplicity and rugged design. Designed to be compact and self contained; the GrayChain 3570 does not require a stand-alone power pack. All the gripping pressure and spinning torque are generated at the drill pipe spinner.
Safety First Regardless of how enthusiastic you may be about beginning the job at hand, take the time to ensure that your safety is not jeopardized. A moment’s lack of attention may result in an accident, as can failure to observe certain simple safety precautions. The possibility of an accident will always exist.

Hanging the Spinner The GrayChain 3570 should be hung using a wire rope that is ½” or greater and that is in accordance with acceptable practices. Attach the wire rope through the shackle at the top of the spring hanger assembly. Use of the GrayChain 3570 without the spring hanger assembly will shorten the life of the tool and cause improper operation which may lead to accidents.
Back Up Cables The two lugs at the back of the GrayChain 3570 are to be used with two back up cables. The two lugs at the end of the GrayChain 3570 are to be used with two back up cables. These two cables will restrict the rotational movement to 1’...
Operation Figure 5 1. With the doors open, swing the GrayChain into position on the drill pipe. Bring the 3570 to the correct height. Approximately 12” above the tool joint, position the 3570 onto the pipe making sure that you do not run the tool on the pipe upset or tool joint. 2.
Additional Adjustment Tension Adjustment When the chain stretches or is getting too worn to obtain a proper bite, loosen the 1” Hex Head Cap Screws on the motor mount, loosen the lock bolt on the Chain Retainer and move the motor toward the rear of the spinner. Reposition chain retainer and retighten lock bolt. Oversized Roller If motor is adjusted all the way to the rear and proper bite is still not obtained, replace standard idler roller with the 4”...
Troubleshooting Problem: Cause: Solution: Spinner does not clamp or Lack of air pressure. Air supply should be 100-125 psi @240 clamps slowly on drill pipe CFM. (or unclamp). Air hose, both supply and cylinder hoses are free, not pinched and without leaks. Check all connections for leaks or restrictions.
Page 20
Problem: Cause: Solution: Air motor lacks Place several drops of SAE 10 lubrication. non-detergent oil directly in motor supply ports; restart. Air motor failure. Remove air motor and install motor repair kit or replace. Motor mount loose Disconnect air supply line. Loosen on case, allowing capscrews on motor mount and move chain to bunch and...
The GrayChain 3570 has been designed with the ease of repair as an important feature. The 3570 is comprised of modular components so that any problem can be easily detected. Every component can be either repaired or replaced in the field keeping down time to a minimum.
5. Feed the new chain into the spinner starting at the left Drive Roller and then to the left idler sprocket. 6. Feed the chain with slack behind the motor sprocket. 7. Now feed the chain to the right side of the case, first behind the right idler sprocket and then behind the right drive roller.
Idler Sprocket Sub Assembly To remove one or both of the Idler Sprocket Sub Assemblies, the following procedure should be used: 1. Make sure the GrayChain is off the drill pipe connection and in rest position on the derrick. 2. Shut down the supply of power from the source or from the shut off valve. 3.
Lubrication The 3570 should be inspected and greased each week. For higher ambient temperature up to 86° Fahrenheit (30° Celsius) we recommend to use NLGI grade 2. The grease points are listed below. Lubrication Chart Start maintenance only when supply lines are disconnected and when all pressure has been released.
