Abstract

A remote oil drain system and method, which includes a drain fitting with a hose end that can be coupled to a hose, a drain plug end, and a flange at the intersection of the hose end and the drain plug end. The flange having a key that prevents rotation when interfacing with a corresponding keyway. The drain plug configured to engage with internal threads of the drain fitting. A mounting member configured to be coupled to the chassis, its profile allowing the drain plug end of the drain fitting to pass through to the flange. The mounting member having a keyway to interlock with the key of the drain fitting flange. A locking member engaged with the externally threaded surface of the drain fitting and the proximate the mounting member.

First claim

The invention claimed is:

1. An agricultural vehicle comprising:
a chassis;
an oil pan, including a drain;
an oil pan drain hose having a first end and a second end, wherein the first end is cooperatively coupled to the drain;
a drain fitting including:
a hose end configured to be cooperatively coupled to the second end of the oil pan drain hose;
a drain plug end, the drain plug end having an externally threaded surface on an outer surface of the drain plug end and having internal threads on an inner surface of the drain plug end;
a flange, located at an intersection of the hose end and the drain plug end, the flange extending radially outward from the hose end and the drain plug end and having a key configured to prevent rotation upon interfacing with a corresponding keyway;

a drain plug, wherein the drain plug includes external threads on a threaded end configured to physically engage with the internal threads of the drain plug end of the drain fitting;
a mounting member, configured to be coupled to the chassis, the mounting member having a profile configured to allow the drain plug end of the drain fitting to pass through to the flange until the flange is located proximate a mounting member interior surface, the mounting member including a keyway in the profile to interlock with the key of the drain fitting; and
a locking member with interior threads on a locking member interior surface for physically engaging with the externally threaded surface of the drain fitting and configured to removeably engage with the mounting member on an exterior surface of the mounting member.

2. The agricultural vehicle of claim 1 , wherein the first end of the oil pan drain hose is cooperatively coupled to the drain by an adapter.

3. The agricultural vehicle of claim 1 , wherein the drain fitting is made of a ferrous material.

4. The agricultural vehicle of claim 1 , wherein the hose end of the drain fitting includes hose barbs configured to physically engage with the oil pan drain hose.

5. The agricultural vehicle of claim 1 , wherein the locking member is a jam nut.

6. The agricultural vehicle of claim 1 , wherein the mounting member is removeably coupled to the chassis.

7. The agricultural vehicle of claim 1 , wherein the drain plug includes ports through the threaded end, configured to allow a fluid pass through for draining.

8. A remote oil drain system comprising:
a drain fitting including:
a hose end configured to be cooperatively coupled to a hose;
a drain plug end, the drain plug end having an externally threaded surface on an outer surface of the drain plug end and having internal threads on an inner surface of the drain plug end;
a flange, located at an intersection of the hose end and the drain plug end, the flange extending radially outward from the hose end and the drain plug end and having a key configured to prevent rotation upon interfacing with a corresponding keyway;

a drain plug, wherein the drain plug includes external threads on a threaded end configured to physically engage with the internal threads of the drain plug end of the drain fitting;
a mounting member, configured to be coupled to a chassis, the mounting member having a profile configured to allow the drain plug end of the drain fitting to pass through to the flange until the flange is located proximate a mounting member interior surface, the mounting member including a keyway in the profile to interlock with the key of the drain fitting; and
a locking member with interior threads on a locking member interior surface for physically engaging with the externally threaded surface of the drain fitting and configured to removeably engage with the mounting member on an exterior surface of the mounting member.

9. The remote oil drain system of claim 8 , wherein a first end of an oil pan drain hose is cooperatively coupled to a drain by an adapter.

10. The remote oil drain system of claim 8 , wherein the drain fitting is made of a ferrous material.

11. The remote oil drain system of claim 8 , wherein the hose end of the drain fitting includes hose barbs configured to physically engage with an oil pan drain hose.

12. The remote oil drain system of claim 8 , wherein the locking member is a jam nut.

13. The remote oil drain system of claim 8 , wherein the mounting member is removeably coupled to the chassis.

14. The remote oil drain system of claim 8 , wherein the drain plug includes ports through the threaded end, configured to allow a fluid pass through for draining.

15. A method of safely installing a remote drain assembly during an installation onto an agricultural vehicle, the method comprising:
filling an oil pan of the agricultural vehicle with oil prior to the installation on the agricultural vehicle, the oil pan having a drain and a hose cooperatively coupled thereto at a first end of the hose, the hose having a second end cooperatively coupled to a drain fitting made of a ferrous material;
coupling an installation member to the drain fitting, the installation member extending through a hole in a chassis of the agricultural vehicle;
during the installation of the oil pan onto the agricultural vehicle, pulling the drain fitting through the hole in the chassis of the agricultural vehicle; and
mounting the drain fitting to a mounting member, the mounting member cooperatively coupled to the chassis of the agricultural vehicle.

16. The method of claim 15 , wherein the mounting member is removeably coupled to the chassis of the agricultural vehicle.

17. The method of claim 15 , wherein the agricultural vehicle is a tractor.

18. The method of claim 15 , wherein the mounting member is irremoveably coupled to the chassis of the agricultural vehicle.

19. The method of claim 15 , wherein the installation member is magnetically coupled to the drain fitting.

20. The method of claim 15 , wherein the installation is physically coupled to the drain fitting.
