PARTIAL HYDRAULIC

SCHEMATIC FOR THE

LOW COAST MODULATOR VALVE

520U

HOW TO USE THIS MANUAL:

All castings and spacer plates have been numbered so they can be identified

in the Valve Body Mapping oil circuit diagram. Example: 520U passage is located 

in the Lower Valve Body Upper side (500U series). This passage can now be located

in the partial oil circuit diagram and matched up to the passage in the 

Lower Valve Body Upper side as shown above.
