Inspect the valves and plugs for scratches, burrs, nicks, or scores. Minor surface scratches on steel valves and plugs can be removed with crocus cloth but
do not round off the edges of the valve or plug lands. Maintaining sharpness of these edges is vitally important. The edges prevent foreign matter
from lodging between the valves and plugs and the bore.
Inspect all the valve and plug bores in the valve body. Use a penlight to view the bore interiors. Replace the valve body if any bores are distorted or
scored. Inspect all of the valve body springs. The springs must be free of distortion, warpage or broken coils.
Check the two separator plates for distortion or damage of any kind. Inspect the upper housing, lower housing, 3-4 accumulator housing, and transfer
plate carefully. Be sure all fluid passages are clean and clear. Check condition of the upper housing and transfer plate check balls as well. The check
balls and ball seats must not be worn or damaged.
Trial fit each valve and plug in its bore to check freedom of operation. When clean and dry, the valves and plugs should drop freely into the bores.
Valve body bores do not change dimensionally with use. If the valve body functioned correctly when new, it will continue to operate properly after
cleaning and inspection. It should not be necessary to replace a valve body assembly unless it is damaged in handling.
