Disassembly (Fig. 52)
1.Wash valve in solvent and thoroughly dry. Mount valve carefully in a vise ensuring the mounting pads are against the vise jaws.
2.Remove boot retainer (10) from the valve housing
(9).

Inspection (Fig. 52)
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 (5) 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.
Reassembly (Fig. 52)
1.Coat all new O±rings and back±up rings with hy- draulic oil. Install new O±rings (8) and new back±up rings (7) into the bore of the valve housing (9).
2.Install ball (4) and spring pin (6) into the spool (5) so the ball is held in by the pin. Make sure both ends of the spring pin are flush with the sides of the spool.
3.Carefully install boot (12) onto the valve stop (13).
