Assemble Steering Unit
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 lint or other matter can get into the
hydraulic system and cause damage. Do not use a
coarse grit or try to file or grind these parts.
NOTE: Lubricate all seals with clean petroleum jelly
such as Vaseline.
Do not use excessive libricant on seals for meter
section.
Refer to parts listings covering your steering unit
when ordering replacement parts. A good service
policy is to replace all old seals with new seals.
