Install control valves by sliding valves into appropriate bores. DO NOT scratch or damage valve body. Wrap shaft of small screwdriver with vinyl tape and insert valves into bores using screwdriver as necessary.
Install 1-2 accumulator valve, then align 1-2 accumulator retainer plate with 1-2 accumulator valve from opposite side of control valve body. Install return spring, 1-2 accumulator piston and plug. See Fig 1. While pushing plug or return spring, install retainer plates. See UPPER VALVE BODY RETAINER PLATE IDENTIFICATION
