Abstract
A method and system for reducing leakage of hydraulic oil from a hydraulic outlet on a tractor, which involves removal of the female quick connect coupler from a legacy original equipment selective control valve and inserting into the void the following: a three part insert with a front stepped diameter segment, a back section, which is screwed into front stepped diameter segment, a sleeve which is configured to be inserted after a front O-ring is adjusted and a leading portion of a retention bolt.
Claims20
A method of reducing environmental soil contamination caused by infiltration of hydraulic oil leaking from a tractor, comprising the steps of:
- provide a selective control valve for provisioning hydraulic oil under pressure and having a first coupler orifice therein and a second coupler orifice therein;
- said first coupler orifice having a first quick release mechanism disposed therein;
- remove a snap ring exposing said first quick release mechanism;
- remove a barrel from said first coupler orifice;
- insert through said first coupler orifice, an insert having an insert maximum diameter portion, intermediate diameter portion a smaller than intermediate diameter portion and an interior back face;
- install a retention bolt through a washer into an internally threaded portion of said smaller than intermediate diameter portion at said interior back face;
- and
- tighten said retention bolt, thereby causing said insert to move further into said selective control valve.
A system for reducing leakage of hydraulic oil from a legacy original equipment selective control valve comprising:
- a front stepped diameter portion with:
- a fluid channel therethrough, a face orifice therein, a front stepped diameter portion longitudinal axis, and a portion of said front stepped diameter portion being sized and configured to be inserted in a coupler orifice in a selective control valve;
- a back portion with a back portion longitudinal axis, said back portion, having an oil receiving orifice extending through said back portion transverse to the back portion longitudinal axis;
- the face orifice being in fluid communication with the oil receiving orifice;
- a first O-ring disposed about said back portion longitudinal axis;
- and
- a threaded retention fastener configured to rotatably mate with a threaded interior portion of said back portion, and configured to cause retention of said front stepped diameter portion with respect to the selective control valve, when said threaded retention fastener is advanced into said threaded interior portion of said back portion.
A system for reducing leakage of hydraulic oil comprising:
- a portion of a selective control valve after having removed therefrom, a first quick release mechanism from a first coupler orifice therein;
- a front portion with an insert maximum diameter characteristic, with an insert exterior face;
- a back portion with an interior section having an oil receiving orifice therein;
- a front O-ring disposed between the insert exterior face and the oil receiving orifice;
- and
- a back O-ring is disposed between said oil receiving orifice and a back portion terminal end.
