Control Valve Module Disassembly

NOTE

The control valve module assembly springs and other parts can be mistakenly interchanged. Tag each part

with its item name as it is removed and use valve tray set (J33163) to simplify correct valve reassembly.

Remove bolt (5) and two bolts (3) securing the suction filter housing (6).

Remove suction filter housing (6), filter (2), face seal (4), and gasket (1). Discard filter and gasket.

Remove four bolts (7) and wiring harness cover plate (8).

Tag and disconnect electrical connections.

Remove three bolts (10) and control harness assembly (9).

Remove three bolts (12) and rotating clutch solenoid body assembly (11).

Remove eight bolts (16) and stationary clutch solenoid assembly (15).

Remove two bolts (40) and main valve body assembly (87) (see page 0252 00-45 for illustration).

NOTE

Rotating clutch solenoid body disassembly procedures are steps 9 through 14.

Remove two bolts (14) and then remove C3 pressure switch (13) from rotating clutch solenoid body assembly (11).

10.

Check resistance of C3 pressure switch. Maximum allowable resistance is 2 ohms when contacts are closed and must be

20,000 ohms minimum when contacts are open. Check pressure at which switch opens and closes. Both events must

occur between 23-37 psi (104-255 kPa). Test block tool (J33884-25) is used to help make these checks.

NOTE

Solenoid retention pins (24) must be removed from bottom of solenoid body. Note grooved end of pin for

positive retention.

11.

Remove face seal (17), two solenoids (22), and one solenoid (23) by removing retention pins (24).

12.

Remove three smaller O-rings (20) and three larger O-rings (21). Remove three solenoid regulator valves (19) and three

springs (18).

13.

Check resistance of each solenoid. Resistance must be 2-5 ohms.

14.

Remove valve retention pin (25), stop (28), valve (26), and spring (27) from rotating clutch solenoid body (11).

NOTE

Stationary clutch solenoid body disassembly procedures are steps 15 through 20.

15.

Remove two seals (38) from stationary clutch solenoid body (15).

NOTE

Solenoid retention pin (29) must be removed from bottom of solenoid body. Note grooved end of pin for

positive retention.

16.

Remove three solenoid retention pins (29) from bottom of solenoid body (15).

17.

Remove three solenoids (33), six O-rings (34), three solenoid regulator valves (31), and three springs (30).

18.

Check resistances of solenoids. Resistance must be 2-5 ohms.

19.

Remove valve retention pin (32), stop (35), spring (36), and valve (37).
