NOTE: Valve housing with inlet relief valve has one o-
ring on the plug. After o-ring replacement, install relief
valve and plug into valve housing and torque plug to 41-
46 Nm [30-34 lb-ft].
Reassembly
Replace all worn and damaged parts, also a good ser-
vice policy is to replace all seals. Lubricate all seals with
petroleum jelly, and also lubricate all mating surfaces
with good clean hydraulic fluid for ease of reassembly
and to provide instant lubrication between rotating parts
at start-up.
22. Lubricate the spool and install it into the sleeve, align
the centering spring opening of the spool with the
spring notches in the sleeve.
23. In preparation of installing the control spool and
sleeve centering spring set, stand all springs on a
clean flat surface with the notched side of the center-
ing spring pointed down. Next place centering springs
with arched side of each set of three pointing toward
each other as shown above.
24. To install centering springs, first insert spring installa-
tion tool through spring openings in the spool/sleeve.
Insert one end of the entire centering spring set (with
notched side toward the spool/sleeve) into the spring
installation tool. Compress extended ends of the cen-
tering spring set and push springs into the
spool/sleeve (do not pull on the spring tool), installa-
tion tool will guide the springs through the spool and
sleeve. Increased Input torque spring package has 4
spring spacers 2 on each of the out sides of the six
springs.
NOTE: When spring installation tool is not available, the
centering springs may be installed by hand. First install
two (2) outside springs and add the others one at a time
in between previously installed outside springs.
25. With spring set installed, center spring sets within the
sleeve and push down on the spool until top of the
centering springs are flush with upper surface of the
sleeve.
