The top steel hydraulic line going out of the oil cooler and into
the steering column developed a leak (by rubbing against the bracket
above the radiator) and I thought I would document for others the
options that I discovered to fix it. I called Agco and they did not have the steel line but
said they could get it from a 3rd party source. Unfortunately, I needed
to get the tractor operational immediately and couldn't wait 3 days for
it's delivery. The 90 degree brass coupler attached to the oil cooler that the steel line (with a
flare) screwed into has a non-standard hydraulic fitting. I went to
Oreillys and they didn't have anything. I went John Deere and they
didn't have anything. Turns out that my Agco dealer had what he
referred to as "Oliver" fittings so he made a 7 foot hose to get me
operational and I bypassed the steel line. The "Oliver" fitting used was a crimp on 90 degree so not something from the 1970s. These fittings were just laying in his drawer loose so no identification. The
tech didn't know the official name of the "Oliver" fitting style. On
the other end, I had a JIC fitting so that was easy. Curious if anyone
knows what that style of fitting is actually called for future
reference? My internet search hasn't produced anything. To make it easy on me to tighten
the connection, I pointed the 90 degree out. I am going to remove and
point it inward so I can put on back the nose grill. The steel line hasn't been removed yet as can be seen in the picture. I ran the rubber hose over the top of the radiator for now. The area where the steel line runs beside the radiator is limited in size so not sure how that is going to fit without buying the steel line. I am guessing a rubber coated clamp is better in the long run to avoid the hole again. Looks like I need to remove the hood to see what I am doing on the final repair. Are there better ways to fix this in the long run? What have others done in this situation?  ------------- 80 7010, 80 7020. 67 190XTD Series I w/500 Loader, AC 2000 Plow, AC 4 row Planter, AC 77G Rake, Member Indiana A-C Partners, Member TAC |

| I have areally good welder in our neighborhood that welds hole in steel line for me. He has a special dye he can put on the line to test for leaks. I have one on my 190 now that drips by the hydraulic pump I need to take to him. Took 50 years for that leak fix it and be good another 50. |

| There are some steel lines on some tractors here that have been brazed. I plan to do that to a coolant bypass line on the WD project |

Had a line on a 190 that went to the hydraulics and it split right on the 90 degree bend back by the flywheel area. Lit up the torch and brazed it shut some 30+ years ago. Brazed up other lines over the years too, even an injector line on a d17 diesel. ------------- He who says there is no evil has already deceived himself The truth is the truth, sugar coated or not.

I have had good luck with both brazing lines and bending new ones. I would not use brass fittings on a hydraulic system - they do not like pressures that high. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '61 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

The brass fittings I refer to look to be original equipment. They had orange paint on them and require the "oliver" fitting. I noticed no one has commented on what an "Oliver" fitting is really called. Going to pickup the metal hydraulic line later this week from Agco that I bought to see if it will fit. I have never brazed anything so not sure what kind of luck I would have. ------------- 80 7010, 80 7020. 67 190XTD Series I w/500 Loader, AC 2000 Plow, AC 4 row Planter, AC 77G Rake, Member Indiana A-C Partners, Member TAC |

A local hydraulic shop can braze your line pretty cheap if you are not comfortable trying that. ------------- '49 G, '54 WD45, '55 CA, '56 WD45D, '57 WD45, '58 D14, '59 D14, '60 D14, '61 D15D, '66 D15II, '66 D21II, '67 D17IV, '67 D17IVD, '67 190XTD, '73 620, '76 185, '77 175, '84 8030, '85 6080 |

Inverted flares are used often in the automotive world. Hydraulic brake connections are but one usage of them. Never have heard the term "Oliver Fitting" and must be along the lines of the generic term "Band-Aid". ------------- That's All Folks! |
