REPLACING HIGH PRESSURE HYDRAULIC
FILTER ELEMENT:
Ensure that the system has been shut down and
de-pressurized. Locate High Pressure Filter
housing. Confirm that the element that is about 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. Using the appropiate spanner
wrench or ratchet, turn in a counterclockwise
rotation, (looking at the bottom of the bowl) to
remove the bowl from the head. The first couple of
rotations will seem tight as the o-ring passes 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 because the flow
direction through the element is outside-in. Clean the inside of the bowl if “dirt” is present. Remove the old
element from the filter head by pulling with a rotation 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 cross
threaded into the head. Continue to tighten the bowl into the head, 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 seated properly with in 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 filter element first at 50 hours of operation, then
yearly (500 hours) or when indicated by restriction indicator.
GREASING CUTTERSHAFT -- FLAIL MOWERS
Locate grease zerks on each end of cuttershaft(s),
these are located on the bearing cover. Normal
conditions require one or two pumps in each
bearing, using Lithium-Complex Extreme Pressure
grease confirming to NLGI2-ISO 320 specifications.
This is to be done with a standard grease gun daily
or at
8 hour intervals. CAUTION: Over greasing
may cause premature seal failure.
