4035 hydraulic leak

[ranwin33]

Has anyone had experience replacing the suction hose that joins the metal hydraulic pipe hitch suction assembly. Located right under the drivers platform on the right side of the tractor.

Went to hook my backhoe up yesterday, and when I tried to work the rear hydraulics I got a real bad leak. The schematics I checked indicate the problem is a severely corroded suction hose that is hose clamped to the metal hydraulic pipe hitch suction assembly. It's a ten dollar part, and I just as soon not take it to a dealer to replace if its a DIY job, but I'm concerned about how difficult it will be to slip the hose back on the pipe, or if I will need to loosen up the entire assembly.

Thanks,

RW

After a great deal of effort I was able to get the new hose on. You would think a hose would slide right on a pipe coated with hydraulic fluid, but no. I still cannot figure out why this is not a solid pipe from front to rear.

But, the thing is still leaking. Right now I've got two worm clamps doubled up on one end of the hose and tightened down as much as I can and it is still pumping fluid on the ground through that end when I engage the rear hydraulics. The pipe and hose were clean when I put them on so it cannot be grit or anything keeping it from sealing.

I would appreciate any suggestions.

When you put on the 2 worm clamps, did you line up the worm mechanisms? If you did, you need to stagger them not line them up.

Thank you for the reply. Yes they are staggered. On the original installation only one worm clamp was used on each end. I though putting two on the leaking end might help, but it didn't.

Does the metal pipe you are attaching to have any pits in the metal? Or, does it look colapsed? When you slid the new hose on(since it was tight) did it slice/cut the interior of the new hose?

When I checked the pipe before putting on the hose, it seemed fine. The black paint was worn off, but other than that I couldn't feel any rough areas. I don't know how the inside of the hose could have been cut, I squared it up with the end and was able to get it onto the pipe for about the first half inch before it got real tight. When I checked the hose itself before putting it on, it looked fine and solid on the interior.

That is weird that a return line would be giving you such a hard time. I'm out of ideas.

Good luck hopefully it is an easy fix.

Keep us posted on what you find.

Thanks for your suggestions. I am looking to get some wider worm clamps to see if that does not help. Failing that, it is back to the dealer, which seems to be becoming a routine with various hose leaks on this tractor - fuel and hydraulic.

Who do you deal with. Are you dealing w/ Blue Valley Tractor?

Yes, Blue Valley Tractor.
