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.
Claims13
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 thereon 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;
- expose said first quick release mechanism;
- insert through said first coupler orifice, until seated therein, an insert assembly having an insert maximum diameter portion, intermediate diameter portion, a minimum diameter portion, an opposing face, a front O-ring, an interior section, a back O-ring, a back portion, a back flat face portion, and an interior back face;
- by rotatably engaging one of said back portion and said back flat face portion, tighten said interior section toward said minimum diameter portion at said opposing face, thereby causing an increase in an outside diameter of said front O-ring disposed between said opposing face and said interior section;
- move a sleeve over said back portion until engaged with said back O-ring;
- install a retention bolt through a large washer into an internally threaded portion of said interior section at said interior back face;
- and
- tighten said retention bolt, thereby causing an outside diameter of said back O-ring to increase.

- move a sleeve over said back portion until engaged with a back O-ring;
- and
- provide a large washer which has a larger outside diameter than said sleeve.
