Buying Advice 1st Breakdown - Need advice

[Gregster613]

Well it happened sooner than I expected but what can ya say? Was doing some loader work this afternoon and I hear a "Hissss" look down and see a stream of fluid shooting out just behind the left front tire. I jump off, get a closer look, whoops - I quickly high-tailed it over to the garage and shut her down. The hyd hose going to the bottom & rear of the gear pump had been rubbing against the loader frame and just blew out. I'd never noticed it rubbing before...course why should I be inspecting the fitment of hoses on a brand-new machine? Anyhow, I can see where it attaches to the pump but it then routes up under the cowling below the stearing(sp?) wheel and I have no idea where it ends up at? I have no service parts manual (or active dealer for that matter) and I would just as soon fix it myself. I realize that these kinds of things eventually just happen. I know that because it's new hoses should be covered under warranty but I don't have an active TYM dealer close to me and I'd rather just get it fixed as soon as possible.
So my questions are - - Does any 273 owner out there know where this hose is routed to? Has anyone else had to replace their hose yet? Do I need to dissasemble the entire cowling to get access? Does it end up at or originate from the loader valve? The engine was hot so I couldn't get my hands up in close, but it looked like it "might" just cross over to the loader valve. If so, man what a tight fitment to get it out and back in!!!!
Suggestions, advice, guideance, encouragement...I'm up for any and all.
Thanks for listening....Gregster613

myyaz33, did you happen to send him a service manual .pdf file? If not, I have one I could send if I can get an email address for him.

With out looking into it more I would guess it is a power steering line.

I just took a look at mine today and although I did not see any wear on the hose, I can easily see where it could rub. Will have to keep an eye on it.

I believe the OP has a copy of the service manual now.

Mucho many thanks to MYYAZ33, that file you sent me was exactly what I've been after since getting my 273! I'm pretty sure that hose #9 on page 4-17 is my culprit hose. I haven't yet torn it apart cause after thinking on it for awhile I decided that I'd better call TYM in the AM and ensure that if I do disassemble I won't affect my warranty in any way. It shouldn't, but I'd rather be sure than sorry. I thought that it looked like the hose from the 1st pump and (sorta) looked [from my limited external view] that it was headed in the direction of the loader valve. Without further disassembly I'm still not totally sure but I'd put $ on it being the hose I was talking bout. After viewing the disassembly instructions it sure takes alot of minor items apart to get a clear view of it and I'm thinking that if I remove it from the loader side that if'n I tie some string or wire to it I can just feed it through without all of the costly shop expense (required hours) of getting it replaced. I'd like to get one that's about 3 inches longer and re-direct the attachment at the pump end so that it will hang alongside of the loader arm vice rubbing against it. I'm also going to cut up a piece of bicycle tire to wrap around the hose at the section by the loader for further protection. I'd suggest that other 233/273 owners also consider the tire wrap idea also. I'd never given any thought/worry about the hose rubbing against the loader frame. I figured it was good enough for TYM engineers, good enough for me. Ha! My mistake.
Anyhow, I just want my beast fixed and it'll probably be faster if I do it myself. Just want to be clear/square with TYM so that I don't jeopardize my warranty. I plan on useing it for that occasion that I hope will never come -- ie...some kind of major malfunction, engine, tranny,etc., etc.
Thanks for the file MYYAZ33 and the advise from everyone else. I'm not fixed yet but I feel that I'm sure on the right pathway now. Man, it's just so great to have a whole network of assistance, suggestions, guideance, advice, and "Oh yeah I've done that" right at the fingertips! Thanks to all TBN'ers...... Gregster613

I have had 3 hoses burst. Both steering cylinder hoses and the main hydraulic hose. I think I see more issues with rubbing because I live on the top of the mountain nearly nothing I do is on flat ground. Frame articulation pulls hoses tighter where they pass any slightly rough surface.

I also am too far from a TYM dealer (since my local dealer went out of business) to be able to get prompt service. Before you tear into anything talk to your dealer and be sure they will stand behind the warranty. Next talk to your service tech and get all the advice you can while assuring the job is done the way they would do it as a dealer.

The hose you are describing sounds like the main hydraulic hose assembly. It leaves the pump and then passes by the fire wall and under the steering wheel assembly before emerging on the other side of the tractor and connecting to the loader valve block. Along the way it rubs on the loader assembly, and both sides of the fire wall. I have had similar trouble with the steering cylinder hoses which run under the engine inside the edge of the frame. Both have burst.

If you end up replacing it yourself save some time and headache and remove the steering wheel before proceeding with the rest of the steering wheel assembly cover. The instrument panel has some fragile tabs which can easily break if the steering wheel is in the way. Once the cover is removed you should have good visual access to all that is needed for this repair.

While you are open to all of the hydraulic hoses for both main hydraulics and steering invest a little money in protecting the delicate hose walls. Our local commercial hydraulics dealer has kevlar spiral protector that the hoses can be wrapped in to protect wear areas. It is a little bit of money that will save hours of hassle and down time. I ran it on every hydraulic hose I could get at, paying particular attention to anything passing tightly across the firewall, brackets or making a hard turn. The same commercial hydraulics dealer was able to make replacement hoses in just a few minutes at around $50-$90 a piece depending on length and specialty ends. I then took the burst hose to my dealer for replacement under warranty (spare parts since I already bit the bullet to get it up and running).

If you proceed on your own, be sure your dealer is involved and willing to back you up with the warrant that sold you on your machine. Since protecting my hoses I have had no further hose issues. FYI if you are sidehilling and working uneven ground like myself also keep an eye on the frame bolts connecting the frame to the HST, they tend to loosen with frame articulation.

Good Luck,
snshall

Update to Hydraulic hose troubles..with a Lot of pictures. I got my baby back last week and all is well once again. And "Oh Yeah", it cost A-lot of $ but that's just the way it goes at times I guess. In addition to my burst hose, I had my Top-N-Tilt system w/3 spool valve installed also. I just wasn't comfortable enough to tear my working hydraulic system apart. Nor do I have all the correct tools or time to run around trying to find the exact fittings I'd need to put it all back together. However, now that I see where & how it's correctly dissambled/assembled and I think on the Vast sums of $ it seems to cost for labor....(& fittings says my installer) any future hose replacements/additions will be peerformed by myself! At my initial tractor purchase I'd bought the rams, Q-disconnects, & ordered the bracket kit to hold it all in place...which is why I was so,so,so very surprised by the cost of install! Anyway, my initial problem was a hose bursting and that's what I consider to be just a part of owning/operating a machine. I'm extremely proud of and greatly enjoy using my new hydraulics. as you can see by the many pics I've attached. I have several more adjustments to make within my "learning to properly use" curve, but I'm getting there. Thanks to all for the advice, tips, and the Service Manual. All were a great help!
I'm too long winded so here is a snap-shot of the pics. Feed line hooks into side of loader block. I thought/know I took that picture but it wasn't on my camera.

Hyd10..View of power steering hoses (which mechanic said were fine) were NOT fine..had initial wear groves that I added bicycle tire pieces to protect for awhile longer. Thanks to snshall tips, I looked very closely at them!
Hyd11..Hyd lift arm installed..old adjustable arm added to left side by me

Happy Tractor'n to all........Gregster613

are there supposed to be pictures attached?

My bad, I thought they were in the message. Sorry. I'll try again.
