REPLACEING HIGH PRESSURE HYDRAULIC
FILTER ELEMENT:
Assure 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, and use the appropiate 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 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
due to 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. Install the new element into and on the mounting boss within the head; assure that
the element is fully seated on the boss. Clean and inspect the o-ring that is affixed in the bowl, lubricate with
oil. Using a clockwise rotation, screw the bowl back into the head, assuring that the bowl has not been cross
threaded into the head. Continue “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 assures 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. This is first to be done at 50 hours of operation, then yearly
(500 hours) or when indicated by restriction indicator.
GREASING CUTTER SHAFT-FLAIL MOWERS
Locate grease zerks on each end of cutter shaft(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.
