Relief Valve Service
Note: The relief valve (Item 19) must be replaced as
a complete assembly. Disassemble parts for cleaning
and inspection only.
1. Disassemble relief valve parts. Do not attempt to re-
move the valve seat. It is installed with thread locking
compound at the factory. Count number of revolutions
it takes to unscrew the relief valve adjusting screw so it
can be installed at the same pressure setting.
2. Inspect ball for burrs or roughness. Inspect relief
valve bore and seat in valve block.
