2440 Hydraulic Low Pressure Line AR92992

The 2440 tractor we have had some of the lines that run from the front of the tractor to the trans/clutch housing rubbing from being bent over the years. Finally one rubbed a hole in another. This happened to be the low pressure oil line, part #AR92992. I used a bit of garden hose to get by but noticed that the line, for a tractor with Hi/Lo on the dash, no longer was available from Deere. Fail on Deere's part. I couldn't get my hose clamps tight enough to seal the garden hose on the old line even after I did my best to put a bit of a rolled edge on the ends. I ended up ordering AT22143. The line is exactly the same as AR92992 in terms of length and bends as what came off my later (after serial # break) 2440 with Hi/Lo... EXCEPT THE END! The end that goes into the clutch housing was too small by a long shot.

Solution: The pipe on the old and the new line are copper and the ends are soldered on, not welded. Took both lines to my local welding shop. The took the end off the old line and put it on the new line. I dropped it off at lunch and it was done at 4 PM. They were able to do this without cutting the line so I did not lose any length on the new line since they were soldered. Since the connection up front to the oil cooler is a hose and not a hard connection there would have been some room, about 3/4" anyways, if they had to cut it. Line cost was $75 at Deere and cost another $90 at the welder. May be more than some are willing to spend but I am happy not to be spilling any hy-gard for what it cost!

Hopefully this helps someone out in the future!

Are you sure the lines are made of copper? I thought they were made of steel and could be brazed.

I could be very wrong on this Jim but they told me the new line was copper and it was soldered so no length was lost on the line. This did come from the guy with clean hands who is always at the front desk so I could have just been told what I wanted to hear as well. Either way the new end looks to be as good as the factory connection.

I agree that large end is soldered or sweated on tube but I have my doubts about line being copper.

I know a lot of the old 2cyl. tractor lines from Deere were steel with a copper looking coating on them. Ends of them were always welded on somehow ? I never could get them apart with heat.

Good to know for the future. Many of our lines from the pump to clutch housing are bashed up and I figure this will not be my last experience with this situation.

I'll get a pic of the end. I'm curious now how it was done and might go back and ask because you would never know it is not factory.

Hi Jim
I don't know what some of those lines Deere use are made from. I tried doing an over the motor line on a 4010 and an internal line for an 1830 as it
was on back order and the guy needed the tractor. neither of those brazed, they just fractured at the repair spot. I'm kinda wondering if some of them
are some goofy junk alloy, or chrome molly or something as they seem pretty light weight for what they are, and you can make em glow read with a
torch!.

I remember seeing several hyd lines on 4020/3020's brazed back when I was employed by a JD dealer. I don't remember seeing any utility tractor hyd lines brazed.

It would take all of about ten minutes to chuck that machined end with the O-ring groove in the lathe and bore the old tube out, then another 10 minutes to silver braze it onto the new line. $90??? What's their hourly rate?

Doesn't matter to me. I don't have those tools or that ability, couldn't find a used line, and my tractor is now fixed. I am pleased with the work and my decision. I think their rate is $120 an hour. Only about two shops within half hour of where I am.
