Disassembly (Fig. 101)
1. Plug all ports and clean the outside of control valve
thoroughly.
2. Remove two (2) screws with lock washers (item 7)
that secure end cap (item 12) to control valve. Remove
end cap.
3. Retain spool to prevent it f rom turning. Remove
screw (item 5), spacer (item 13), spring (item 20) and
washer (item 6) from control valve.
4. Carefully slide spool (item 8) from housing bore.
5. Carefully remove O- rings (item 4) from spool bore.
Take care to not damage spool bore or O- ring cavities
during O- ring removal.
6. Remove detent plug (item 16), O- ring (item 18),
spring (item 17) and detent ball (item 1).
7. Remove plug (item 9) with O- ring (item 21) and lock-
out seat (item 22) with O- ring (item 23) from valve body.
