Oil Dispenser Maintenance

Oil Dispenser Maintenance

Oil Dispensers are a type of fluid dispenser used to safely store, transport and dispense many types of hydraulic fluids used to service aircraft engines, aircraft power units and other hydraulic aircraft and servicing equipment. They are designed to be used for various fluids for engines, gears, transmissions and other aircraft components and can safely handle hazardous fluids such as Skydrol and Hyjet.

The proper servicing of the hydraulic aircraft components is required to maintain flight safety and prolong the engine life of the aircraft. The Oil Dispensers protect the hydraulic fluids from moisture and airborne contaminants which allows the maintenance technician to service and replenish the fluids in the aircraft hydraulic systems with clean, uncontaminated fluids.

 

Oil Dispenser Design

Oil Dispensers typically consist of a fluid reservoir, manual hand pump or air operated hydraulic pump, filter assembly, and a long fluid delivery hose. They are typically made from either stainless steel or from a durable, lightweight polyethylene material that is impervious to petroleum-based fluids, such as hydraulic fluids and solvents.

Oil Dispensers can be smaller 1-quart to 2-gallon hand-carried units, larger 5 to 20-gallon hand towed dispensers or vehicle towed units that can accommodate 55-gallon drums. Many models are often available in several different colors to easily identify the fluid type contained in the dispenser. A number of standard and special hose end fittings, couplings and accessories are available to create a wide variety of hose end configurations for multiple uses.

The pumps can pressurize the system up to 200 PSI and pressure gauges are available on some units to monitor the system pressure. When the Oil Dispensers are not being used to service aircraft, they can be used as a convenient reservoir for fluid storage.

 

Oil Dispenser Maintenance Requirements

As in any other type of aircraft maintenance equipment, the proper maintenance of the Oil Dispensers is required to ensure that the unit functions correctly and to help prevent costly downtime and repairs.

The following maintenance items should be performed at either a 6-month or 12-month maintenance schedule, depending on the usage of the equipment. The performance of each of these items is important to maintain the optimal functionality of the equipment.

  • The oil filter in the equipment must be changed regularly to ensure that the oil that is dispensed remains clean. The schedule to change the filter can be either a set timeframe, a time based on usage of the equipment, or determined by the analysis of fluid samples taken at frequent intervals. The schedule used should be outlined in the organization’s operating policies.
  • The equipment’s fluid reservoir should be checked for leaking or any damage that could cause a premature rupture of the reservoir.
  • All hoses should be checked for leaks, cracks or damage to the connections at their ends.
  • The handle on the manual pump should be inspected to ensure that it is operating properly and all of the mounting hardware is not missing or loose. If the force required to activate the handle is higher than normal, it could indicate that the filter is clogged and needs to be replaced.
  • The wheels should be checked for proper ease of rotation and inspected for significant damage.
  • The towing handle or tow bar eyelet should be inspected for any excessive wear, cracks or deformation.
  • If a pressure gauge is installed on the equipment, the pressure gauge will need to be calibrated to ensure it meets its manufacturer’s specifications.
