Remove the Valve Spool and Sleeve
CAUTION:
Handle the valve spool with care. Damaging the precision
machined surface of the spool can cause the air valve to seeze.
See Figure D‐6.
1. Carefully slide the valve spool (1) out of the valve sleeve (2). Set the
valve spool aside onto a clean cloth.
See Figure D‐7.
2. Remove the two M4 screws (5), and then separate the upper detent (6)
and spring (4) from the air manifold (3).
3. Remove the two M5 screws (2), and then remove the flange (1).
See Figure D‐8.
4. Use a socket or similar object to push the valve sleeve out of the air
manifold.
NOTE:
The valve spool and sleeve are a matched set and cannot be
exchanged with parts from another air valve assembly. If either the spool or
sleeve is damaged, they must be replaced with a new valve assembly.
CAUTION!
Do not scrape the valve spool or sleeve. Clean them with mineral
spirits or any non‐chlorinated cleaning solvent and a soft cloth. Do not use
abrasives such as sandpaper or emery cloth. Be careful not to round off the
sharp edges of the spool lands.
