Control Valve Disassembly (Fig. 66)

1.Wash control valve in solvent and dry it thoroughly.

2.Mount control valve into a vise so the mounting pads are against the jaws of the vice and snap ring (14) faces up.

Note: Remove check valve seat (5) only if it needs re- placement; it is press fitted in.

3.Remove plug (1) and O±ring (2) from the valve body

(7). Remove spring (3), ball (4), cam pin (6).

4.Repeat step 3 for the other plug (1).

5.Remove snap ring (14) from the bottom of the valve body (7). Remove spool snap ring (13), spring retainer (10), spacer (12), and spring (11).

6.Push and twist spool (8) carefully out of the valve body (7). Set spool aside.

7.Remove O±rings (9) using a soft hooked scribe or a thin screwdriver and being careful not to scratch the valve bore finish.

Control Valve Inspection (Fig. 66)

CAUTION

Use eye protection such as goggles when using compressed air

1.Wash all parts in solvent. Dry parts with compressed

air.

2.Inspect spool (8) for bending and flatness. Signs of wear on one side of the spool may indicate it's bent. Re- place a worn or damaged spool if necessary.

3.Inspect parts for wear or damage, and replace if necessary.

Control Valve Reassembly (Fig. 66)

1.Coat all new O±rings with hydraulic oil. Install new O±rings (9) into the bore of the valve body (7).

2.Coat spool (8) lightly with hydraulic oil. Push and twist spool carefully into the valve body (7). Avoid dam- aging O±rings (9).
