How to Drain the HCU
Make sure to shut down the system before draining
the oil in the unit. Please allow a couple of hours for
the system to cool down if the system is hot. The
drain plug is located in the hydraulic reservoir,
Figure Mnt-RP-0014. Remove the metal plug and
drain the oil completely out of the system. Screw
the metal plug back in after all the oil is drained out
of the system. The drain plug uses SAE-8-3/4-16
UNF, so do not apply more than 54 ft-lbs. of torque
to tighten the plug.
How to Clean the Oil Cooler
1.
Schulte recommends pressurized water or compressed air to be sprayed parallel to the direction of the
fins to clean the external dust and debris. The pressurized water or compressed air spray should be
placed on the opposite side of the air flow to remove air borne contaminants.
2.
Please make sure to properly seal the other components in the system like the fans and motors etc.
before cleaning the cooler to avoid contamination.
3.
For internal cleaning, please flush the cooler with anti-freeze solution to get rid of the internal
contaminants.
4.
For both internal and external cleaning, it is the responsibility of the authorized personnel to use
compatible fluids that work well with metals like Aluminum. Otherwise, it leads to cooler corrosion.
TOP BUCKET LINKAGE
Check nuts and bolts for tightness after the first 8 hours of operation and then weekly thereafter. Check the
condition of cotter pins, roll pins, and other fasteners weekly. Replace if necessary. Be sure nuts and bolts are
properly torqued.
HUBS AND SPINDLES
Check hubs weekly for bearing play and condition of seal. .
Greasing and Installation
It is recommended that hubs are dismantled, cleaned and repacked every year. Use the diagram and following
instructions for maintaining the wheel hubs. Whenever a worn or damaged seal is replaced the bearing
assembly should be cleaned and repacked with a good grade of wheel grease.
Always wear protective gloves when handling grease
