Note: Bolts are of different lengths and their locations are different.

8. Carefully ease body from case while unlocking and detaching selector lever connecting rod (Z-Link).
9. If valve body is being disassembled:
a. Clean all parts thoroughly in clean solvent and blow dry with moisture-free compressed air.
b. Inspect all valve and plug bores for scores, fluid passages for obstructions, check valve for free movement, mating surfaces for burrs or distortion, plugs and valves for burrs or scores.
c. Use a suitable crocus cloth to polish valves and plugs, if necessary.

NOTE: Avoid rounding sharp edges of valves and plugs with cloth.

d. Replace control valve body if bores or valves are scored beyond point of being cleaned up.
