106. Control Valve Body Disassemble

Caution: Valve Springs can be tightly compressed. Use care when removing retainers and plugs. Personal injury could result.

Important:
^ Position the control valve body assembly on a clean surface during disassembly.
^ All valves, springs and bushings must be laid out on a clean surface. Lay them exactly the way they are removed to aid reassembly.
