Claims
- 1. A method of removing residual used oil from a lubrication system of an engine having a primary oil pump and a scavenging oil pump, the method comprising the acts of:
draining used oil from an oil tank of the lubrication system; adding fresh oil to the oil tank; pumping the fresh oil through the through the lubrication system with the primary oil pump to flush residual used oil from the lubrication system and into a dry sump of the engine; and pumping the residual used oil from the dry sump out of the engine with the scavenging oil pump.
- 2. The method of claim 1, further comprising an act of:
replacing a used oil filter with an adaptor having an outlet to allow the residual used oil to be pumped out of the lubrication system.
- 3. The method of claim 2, further comprising an act of:
plugging uppermost ports of the adaptor while leaving a lower most port open to provide the outlet to allow residual used oil to be pumped out of the lubrication system.
- 4. The method of claim 3, further comprising an act of:
attaching a drain line to the lower most port to allow residual used oil to be directed to a waste receptacle upon being pumped out of the lubrication system.
- 5. The method of claim 4, wherein the drain line includes a clear portion to allow a user to observe when substantially all of the residual used oil has been pumped from the lubrication system.
- 6. The method of claim 1, further comprising an act of:
separating a separable joint of a first fitting at a discharge port of the engine to provide an outlet to allow the residual used oil to be pumped out of the lubrication system.
- 7. The method of claim 6, further comprising an act of:
replacing a used oil filter with a bypass adaptor.
- 8. The method of claim 7, further comprising an act of:
installing a second fitting onto a portion of the first fitting to allow residual used oil to be directed away from the engine.
- 9. The method of claim 8, further comprising an act of:
attaching a drain line to the second fitting to allow residual used oil to be directed to a waste receptacle upon being pumped out of the lubrication system.
- 10. The method of claim 9, wherein the drain line includes a clear portion to allow a user to observe when substantially all of the residual used oil has been pumped from the lubrication system.
- 11. The method of claim 1, further comprising an act of:
stopping the scavenging pump by turning the engine off once substantially all of the residual used oil has been pumped from the lubrication system.
- 12. The method of claim 11, further comprising an act of:
adding make up oil to the oil tank to compensate for the residual used oil flushed from the lubrication system.
- 13. The method of claim 1, wherein the primary oil pump and the scavenging oil pump are gear pumps.
- 14. The method of claim 1, wherein the primary oil pump and the scavenging oil pump are gerotor pumps driven directly by a crankshaft of the engine.
- 15. A method of retrofitting a lubrication system having an oil line adapted to deliver oil from a dry sump of an engine to an oil tank, the method comprising acts of:
removing an original fitting that provides a connection between the oil line and a port in the lubrication system; connecting a first end of a replacement fitting having a separable joint to the oil line; and connecting a second end of the replacement fitting to the port to retrofit the lubrication system.
- 11. The method of claim 10, further comprising an act of:
trimming material from the oil line prior to connecting the first end of the replacement fitting to the oil line.
- 12. The method of claim 11, wherein the first end of the replacement fitting comprises a barbed hose clamp joint.
- 13. The method of claim 12, wherein the second end of the replacement fitting comprises ¼ inch pipe threads.
- 14. The method of claim 13, wherein the separable interface of the replacement fitting comprises an AN #6 joint.
- 15. A kit of parts used to retrofit an engine, the kit comprising:
a first fitting having a separable joint to provide an outlet from a lubrication system of the engine; a bypass adaptor to mount to an oil filter housing of the engine; a second fitting to direct flushed oil away from the engine; and a drain line to direct flushed oil into a waste receptacle.
- 16. The kit of parts according to claim 15 wherein the first fitting has an AN #6 separable joint, a barbed hose clamp joint, and ¼ inch NPT threads.
- 17. The kit of parts of claim 16 wherein the second fitting comprises a right angle fitting
- 18. An adaptor to provide an outlet to allow residual used oil to be pumped out of a lubrication system of an engine, the adaptor comprising:
a central mounting hole having internal threads configured to mate with a threaded protrusion of an oil filter housing on the engine; and a plurality of outlets disposed about the central mounting hole and extending completely through the adaptor in a direction parallel to the central mounting hole, wherein each of the plurality of outlets has internal threads to accept a plug or fitting.
- 19. The adaptor of claim 18, further comprising:
a seal groove configured to accept a seal to prevent oil from leaking between the adaptor and the oil filter housing.
- 20. The adaptor of claim 19, further comprising:
a knurled outer surface of the adaptor to assist a user in gripping the adaptor.
