Flushing Procedures For Warranty Consideration

Flushing Procedures

Contamination in fluid of a hydraulic system is the primary cause of failure.  Before intalling new major components, the system must be completely free of contamination.  Changing the filter element and fluid is not enough to thoroughly clean the sytem.  For this reason we have derived the following list of procedures that when followed step-by-step, will help to insure system cleanliness resulting in longer hydraulic component life.

This Is What You Do After Determining that the Hydraulic Component Needs to be Replaced:
(Remember: Keep It Clean)

  1. Drain the hydraulic fluid from the lowest level in the system.
  2. Remove the old hydraulic pumps and/or motors to be remanufactured.
  3. Remove the filter elements.
  4. Check all suction hoses for kinks, collapsed or flaking liners, or any other obstructions. Inspect all other hoses and fittings in the related system and replace as required.
  5. Check the inside of the hydraulic reservoir for contamination (particles of steel or brass, sludge, dirt, etc.) and be sure that there are no obstructions in the suction or return system components.
  6. Flush and blow out all hoses in the circuit, pipes, tubing, filter housings and reservoir with solvents to remove any contamination.
  7. Reserve flush the oil cooler to remove contaminants.
  8. Wipe out the inside of the hydraulic reservoir with a clean lint-free towel.
  9. Clean all pump and motor fittings to be replaced and install new "O-Rings" as required.
  10. Replace all filter elements, gaskets, and seals as required.
  11. Keep all hoses and fittings capped after cleaning to prevent contamination from entering the sytem.
  12. Reinstall all pumps and motors (on replacement motors, apply a thin coat of lubricant to motor shaft.
  13. Fill hydraulic reservoir, hydraulic pump and motor cases, hoses, lines, etc. with new, clean pre-filtered fluid.  Insure that fluids meet the specifications as shown in your operators manual.
  14. Be sure to fill the pump and motor cases before start-up.  Begin the start-up procedure.
  15. Operate all hydraulic functions, including stroking all cylinders, to insure that any contamination possibly left in the system flows through the new filtration media prior to putting the machine back in service.
