Inspection
Check all mating surfaces. Replace any parts that have
scratches or burrs that could cause leakage or binding.
Clean all metal parts in a clean solvent. Blow dry with air. Do
not wipe dry with a cloth or paper towel, because lint or other
matter can get into the hydraulic system and cause damage.
Do not use a coarse grit emery cloth or try to file or grind any
parts.
Replace all seals when assembling the unit. Lubricate all
seals with clean petroleum jelly before assembling. DO NOT
use excessive lubricant on seals for the meter section.

springs into place in the sleeve. Line up the springs and
center them.
4. Guide the ring down over the sleeve (Figure 10-35).
