I have discovered that the relief valve can be come worn and even scratched severely upon installation by burs on the inside of the cylinder. These burrs originated when the holes were drilled for the cotter key. If you have found this problem and would like to replace your relief valve piston, contact Reed Cearley at [email protected]_ (mailto:[email protected]) . Reed is having some made up at $50.00 each.
