(3) Disassembling lift spool section
① Loosen the socket head bolt (1) and remove
the cap (2). Remove the spool (3) from the
valve housing as a sub-assembly, with the seal
plate (4), wiper (5) and “O”-ring (6) of the
cap side installed on the spool (3).
② Loosen and remove the screw (1) at the
opposite side, and remove the seal plate (2),
wiper (3) and “O”-ring (4).
③ Hold the sub-assembly of the spool (1)
that has been removed in step ① in a vise
equipped with soft jaws (pieces of hard
wood) shown in Figure 3.432, with care not
to damage its exterior. Loosen the cap screw
(2), and then disassemble the spring seat (3)
and spring (4). Remove the “O”-ring (5) and
wiper (6).
Note: Use caution when loosening the cap screw
because it might pop out due to spring

that they can be reassembled properly.
