Hydraulic leak

[super99]

Thought I’d get more feedback here than from the Oliver page. My 1850 is leaving a trail so I can find my way home when plowing snow and a puddle when parked. I washed it today and finally found a pin hole in the metal line going to the front of the tractor. It’s in the bottom line of 2 that run together, of course. No room to get to it out without taking lots of motor parts off first. I’ve brazed these lines before, no big deal but always had them off and drained. Can I braze it on the tractor with oil in the line? Looks like I could unhook the line from the steering unit and get most of the oil out but hoping not to have to. I had put a hose over the line years ago but it must have vibrated ahead and let them rub. Not enough room between frame and motor to get the line out without removing engine oil cooler from the block. Hoping to get it fixed before cold weather again next week. Thanks, Chris

IMHO line will have to come off. Get it drained and clean - then clean it again. Get the paint off from near the area. Will braze easily but outside of line must be dry of oil and clean.

I've had those out. Is there a fitting by the bell housing where it comes apart ?

I would loosen ends, or do whatever to get the oil out, then braze in place. You can tell real quick if there's liquid where you're trying to braze.

Needs to be drained and open on one end. The heat will burn out any residual oil.

No, wish there was

Several years ago I had a hole rubbed in a steel hydraulic line on an Allis Chalmers 5040. All one piece. Hard to find a replacement piece. Local hydraulic place said to cut it out and they sold me a short piece with a compression fitting on each end. I cut out about 6" of the steel. Replaced with about a 9" piece of hose, as recommended. Instructions were to tighten as much as I could by hand, then turn 3/4 of a turn with a wrench. Has held for several years.

I believe the extra length was to allow for some movement as the line was pressurized when I used the loader.

Instructor at tech school told us to wrap clean steel wire, either baling or mechanics, around as tight as you can and braze over the whole bad area. Gives a little more meat to braze to in the thin area.

The answer to your original question is the first word in this sentence unless you are incredibly skilled and even luckier.

steering line they were bad to rub holes in each other
