Thoroughly inspect all components:
•
Piston bore and spool valve bore for scoring or corrosion. If heavy scoring or corrosion
is apparent, the HCU will have to be replaced.
NOTE: Light scoring and corrosion may be removed using 600 grade wet or dry paper,
soaking the paper in engine oil for at least 30 minutes.
•
Check the piston for scores and rack teeth for wear, replacing the HCU if either are
evident.
•
Check the control shaft gear teeth for wear or chipped teeth and renew if either are
evident
•
Make sure the oil drillings in the spool valve are clear of restrictions.
Prior to reassembly of the HCU, thoroughly clean all components and dry with compressed
air.
•
Lubricate new labrynth seals with engine oil, then using fingers only, fit seals to each
side of the seal plate, making sure the seals are located beneath the retaining lugs.
