Hydraulic Hose replacement question for ASV SR 80

Ok, guys, just blew or poked a hole in a hydraulic hose that is under the tracks running along the body of the machine. My fear is that the tracks have to come off to find and switch out that hose. I would like to for someone to tell me I'm wrong :-(

Unfortunately, I'm pretty sure the track needs to come off and the motor frame rotated out so you can get to the fittings on the motor. There may be a way to do it by bending some wrenches and taking small turns but it may be next to impossible to get it back on. I had a 287b with I believe a similar track setup, I always took the track off, hopefully someone will have a better answer for you....

Instead of pulling the track try unbolting the keeper plates on the torsion axles and slide the whole track frame out 6" or 8", should give you alot more room.

Ok, great information.... Let me ask you this - if this is possible, it is probably more than a one man job? Also, how can I better protect those hoses while it is under repair? they have the cloth type cover on them, is there anything else I can add? I'm not the hardest person on a machine but I'm in the woods mostly so I'm sure I'll run a blasted tree/stick in there again sometime. Thanks!!

Its possible, done it on a RC-50 and a couple of RC-100's, Its all just a matter of getting that side of the machine jacked up and blocked safely. Pull the plates off and it should slide fairly easily, if not put a pry bar on it. Should be able to do it with one guy. The key is to not pull the frame all the way off the torsion axles, although on the machines I've done the drive hoses aren't long enough to allow the frame all the way off. For protectant we always layered the hose protectant wrap a few layers thick where it went through the frame, I've heard firehose wears really long, might want to try a scrap of that wrapped around the bundle of hoses. How far do you need to drive it? I would NOT move it if it is completely empty on fluid! How bad is the leak?

The guy who generally works on it works on machinery but just not sure if he's worked on "this" area of the machine before so this information is very helpful. When I was in the woods and saw the puddle I immediately just drove it back to the barn, leaking all the way. Probably 300 feet. It appears to be totally empty but with the puddle in the barn it didn't finish leaking out until I got in there. I was thinking where it is parked there may not be enough easy room to play with the tracks but I'll let someone else determine that. To get it to a clear open space is probably 40 feet. I may just have to call Terex to come out and fix it.... wonder if they take monopoly money? :)

I've been there with the ASV RC100. I'm not a professional wrench turner but have spent a lot of time maintaining the undercarriage. I'd be concerned that I wouldn't be able to replace the hose without getting dirt into the system so I would turn out the drive motor and pull the track to gain access. Now that I visualize this I think you might gain enough access by just turning the motor out only and no track removal. I think your undercarriage may even give you more working room than the RC100. I don't know what hose is punctured but to help you with your down time, you might need a modified open end to tighten the case drain hose fitting on the inside. Good luck.

You need hydraulic open end wrenches like those sold by Martin Sprocket and Gear. Track Loader parts has parts break downs and service manuals for free. Just register and they will e mail for you to down load. On my RC85 with a blown hose we put oil in it. raised the cab, drained the oil tank, swung the drive motor out, dropped the center pan, pulled the hose, capped and plugged the hose ends and fittings, made a new hose with new protective sleeve and put it on. Reverse the process and off you go. Took two of us about 6 hours just taking our time.
