332-1985 Relief Valve Gp, 332-1987 Relief Valve Gp, and 342-8997 Relief Valve Gp




Illustration 1g01944440

Note: The 332-1987 Relief Valve Gp is the line relief valve for the head end of the tilt circuit and the rod end of the tilt circuit. Logging machines will use the 332-1987 Relief Valve Gp for the rod end of the tilt circuit and 332-1985 Relief Valve Gp for the head end of the tilt circuit. IT62H machines will use the 332-1987 Relief Valve Gp for the rod end of the tilt circuit and 342-8997 Relief Valve Gp for the head end of the tilt circuit. The three relief valves are identical except for the pressure setting.
