5. With notch end of spool towards valve body,
install spool, aligning spool notch with pin in stub
shaft.
CA UTION: Because of small clearance between
valve spool and valve body, extreme care must be
taken when assembling these parts. Push the spool
evenly and slowly with a slight oscillating motion
until spool reaches drive pin. Before pushing
spool completely in, make sure dampener O-ring
seal is evenly distributed in spool groove. Slowly
push spool completely in, with extreme care taken
not to cut or pinch O-ring seal.
6. Slide spool spring over stub shaft and work
spring in position.
7. Lubricate cap to worm O- ring seal and install
in valve assembly.
NO TE: If during assembly of valve, stub shaft and
cap assembly is allowed to slip out of engagement
with the valve body pin, spool will be permitted to
enter valve body too far. Dampener O-ring seal
may expand into valve body oil grooves preventing
removal of spool.
a. Remove valve spool spring and disassemble
rotary valve assembly.
b. Press on spool until O-ring seal is cut and
spool can be removed.
c. Replace O- ring seal and proceed with as­
sembly as before.
