Reassembly
Check all mating surfaces. Replace any parts that have
scratches or burrs that could cause leakage. Clean all
metal parts in clean solvent. Blow dry with air. Do not
wipe dry with cloth or paper towel because of lint or other
matter can get into the hydraulic system and cause da-
mage. Do not use a coarse grit, try to file or grind these
parts.
NOTE: Lubricate all seals with clean petroleum jelly
such as Vaseline.
Do not use excessive lubricant on seals for meter sec-
tion.
Refer to parts listing covering your steering control unit
when ordering replacement parts. A good service policy
is to replace all old seals with new seals.
Control End Reassembly
1. Use a needle–nose pliers to lower check ball retainer
into check valve hole of housing. Make sure retainer is
straight (not tilted on edge) in housing, see Fig. 37.
2. Install check ball in housing.
3. Lubricate 5/8” diameter seal and 7/16” diameter seal.
Install seals on check ball seat as shown in Fig. 37.
4. Lubricate check ball seat and seals thoroughly before
installing seat in housing. When installing seat, do not
twist or damage seals. Install check ball seat in housing,
insert open end of seat first, see Fig. 37. Push check ball
seat to shoulder of hole.
5. Assemble spool and sleeve carefully so that the
spring slots line up at the same end. Rotate spool while
sliding parts together. Some spool and sleeve sets have
identification marks, align these marks as shown in
Fig. 38. Test for free rotation. Spool should rotate
smoothly in sleeve with finger tip force applied at splined
end.
