HELP! My 1170 is down and I need it! Blew hydro line.

Get right to the point. Using it for several things right now and was turning in the field when I heard a bang, the steering wheel was ripped from my hand, and it started spraying oil, some in the cab. Of COURSE it is not a easy repair! Nothing on the tractor is easy. Took 15min just to find what blew up. Looking at both the service manual and tractor, it appears to be a hydro line that comes off the top of the trans filter housing with a snaky metal line, then goes to rubber for a bit, then back to metal, in which I cannot even see it, much less replace it.

I don't know why it blew up! The condition does not appear good but I have been fighting with poor steer at slower speeds/ engine speeds, etc. It whines a lot. Sometimes it seems fine.

What I am most worried about is getting to it! Like this almost looks like a cab off repair! Please tell me otherwise! If the book is right, this line goes from the filter housing to the brake valve? Line totally hidden! I have a cab and FIL! It really looks like the shroud over the steering area that runs inside and outside the cab has to come off. But I seem to recall when I tore into this before, Nothing comes apart because that cab was a complete afterthought.

if someone has ideas, please help! I need this tractor asap. I can only assume the line is unobtainable and last time I asked a company to just reinstall a hose on existing hard lines, they said "oh no, we MUST make you a new one from unobtainium because of liability". Those hard lines almost never fail.

It failed because it was 50 years old. Changed a few of those but all were on open station tractors. I never removed any tin that I recall except the top cover where your air cleaner housing is.

I'd imagine you will at least need to remove that.

I just used all rubber hydraulic hose. If memory serves it is JIC 8 female on both ends. About 48" long.

Blew that one last year baling straw,start pulling sheet metal,it's in a daisy of a place made a rubber hose and kept the tube for conversation..

The 11's have a very large air cleaner rite in front of the firewall under the
cowl/hood. You will have to remove the hood and air cleaner assy and then you can
access the brake valve where the top of line fastens. If case engineers had made the
cowl in 3 pieces instead of one, that can't be removed with cab, things on the
firewall would have been MUCH easier to service.

Thanks guys! Clint, that is a good idea to just use all rubber.

Yes about the cowling. If there is some sort of "hood" over the air cleaner, I don't have one. The air cleaner sticks up past the cowl and it just looks unfinished.

Anyway, I can see that if I remove the air cleaner, I can get to the brake valve BUT it sure looks like that hose may screw in on the side RIGHT against the sheet metal. Like no way at all to operate a wrench! If I get irritated enough, there will end up being a fancy hole in the side of that sheet metal to access. I am not pulling the cab over this. Also hoping I can just jam lumber in there and jack the sheet metal away from the fitting but still not sure how this will go.

Thanks for the help guys. I was letting that 1170 eat for once running an offset disc. Probably more work than it has seen in 20yrs.

RG had same thought on all rubber hose. Can't edit my posts but didn't want to leave someone out.

I just hope I am over thinking it. Usually when I go in hot, with everything from a scalpel to a cutting torch, the job gets done much better. It's those jobs that "should" take 10min and take 40hrs that take the life out of me.

The 11's had a much bigger air cleaner to support the turbo's apatite.They stuck up
out of the hood. Engineers just cut a big hole in the removable access cover. Non
turbo tractors like 7-10's had much smaller air cleaners that did not stick up out of
hood, and there was limited access to the firewall area. Like I said earlier, the one
piece cowle should have been a 3 piece with top and 2 removable sides.
You can get a crows foot wrench on a 3/8 extension down there to loosen and tighten
the fitting. I hope you have a good step ladder and long arms and fingers.
