When corrosion, cylinder distortion or thread compounds make threaded cylinder head removal a time consuming job, technicians resort to cutting away the barrel, cutting the gland, torch heating or using a hammer and punch.

Now there is a spanner wrench useable in shop or field that makes high torque threaded gland head removal quick, easy and much safer because it won't slip and it won't damage the rod, head or its spanner slots or holes.

The RGS-310 attaches to piston rods from 1.00" (25.4 mm) to 3.10" (78.7 mm) in diameter. The piston rod is protected by built-in nylon pads. A simple adjustment centers the wrench on the head. The appropriate slot or pin dies engage the head and follow it out as it is unscrewed.

If you are tired of time consuming struggles with threaded cylinder head glands, the unique, new RGS-310 will make life a lot easier. And if you are tired of broken spanners, slipping chain wrenches and damaged threaded glands, the tool-room quality RGS-310 will end the problems for good. It is heat treated to RC 32-38 for maximum strength.
