MAINTENANCE
REPLACING HIGH PRESSURE HYDRAULIC FILTER ELEMENT
Be certain that th e system has bee n shut down and
depressurized. Locate High Pressure Filter housing.
Confirm that the new element to be installed matches
the element p/n on the filter model tag. Example:
V3.0510-06 (world line 100, HD049 model). Locate the
bottom of the High Pressure Bowl. Us ing the
appropriate spanner wrench or ratchet, and turning in a
counterclockwise rotation, (looking at the bottom of the
bowl) remove the bowl from the head, The first couple
rotations will seem tight as the o-ring p
asses the
sealing flats. Once the o- ring has cleared the sealing
flats, the bowl should spin freely. Taking care not to
drop the bowl, finish removing the bowl from the head.
WARNING: Bowl will be full of oil! Pour the oil from the bowl into a container. This oil should be considered
contaminated due to the ou tside-in flow direction through the element. Clean the inside of the bo wl if "dirt" is
present. Remove the old element from the filter head by pulling with a rotating motion. Dispose of the used
element properly. Remove the new element from the packaging. Using your finger, dab and lubricate the o-ring
in the top of the new element with oil. Install the new element into and on the mounting boss within the head.
Ensure that the element is fully seated on the boss. Clean and inspect the o-ring that is affixed in the bowl and
lubricate with oil. Using a clockwise rotation, screw the bowl back into the head, ensuring that the bowl has not
been crossthreaded into the head. Continue to tighten the bowl, using the spanner wrench or ratchet. The
rotation of the bowl will become tighter once the o-ring engages the sealing flats. Once the bowl has bottomed
out, back-off the bowl by 1/6 turn. This ensures that the o-ring is s eated properly within the sealing flats.
Element change out and re-assembly is now complete. Start the machine and inspect the filter area checking
that there is no oil leaking from the filter assembly. Replace the element for the first tim e at 50 hours of
operation, then yearly (500 hours) or when indicated by restriction indicator.
