A blown line stops everything. This one we fix on site.
Hydraulic hose is the failure that ends a shift in one second and sprays oil across the work area. It is also the most genuinely mobile repair there is. We measure, match the fittings, build the new line on the truck, then bleed and test it before you go back to work.

Why this repair belongs in the field
Almost nothing else on a machine is this well suited to mobile work. A hydraulic hose is a consumable. It has a length, two ends, a pressure rating and a bend radius, and if you have hose stock, fittings and a crimper in the truck, you can build the exact replacement standing next to the machine. There is no reason for a piece of equipment to go on a trailer because of a part that gets made up in fifteen minutes.
What takes the time is not the building. It is the identification. Hydraulic fittings come in families that look deceptively alike: JIC, ORFS, NPT, BSPP, code 61 and code 62 flanges, plus metric variants on imported machines. Thread diameter alone will not tell you which one you have, because the seal comes from the seat angle or an O-ring rather than from the threads themselves. Get that wrong and you have a joint that either will not seal or weeps under pressure a week later.
So the old hose comes off and gets used as the pattern. Length is measured between the sealing surfaces rather than end to end, the ends are identified positively, hose type and pressure rating are matched to the circuit, and the routing is reproduced including any bends and clamp points. A line built to the right length that is routed badly will chafe through in a month and put you back where you started.
What we need to knowThe machine, roughly where the line runs, and whether the leak is a drip, a spray or a full failure. A photo of the fitting ends saves everyone time.
What it costsWhat it will cost before the truck leaves, covering the trip and the line. A single hose is a short job and gets billed like one, with no hourly minimum.
What we also checkThe lines running alongside the one that failed, because they have usually lived the same life. Tell us about the machine.
A hose does not burst at random
When a customer says the hose just went, it almost never just went. Hydraulic hose fails for reasons you can see afterward, and reading the failed piece is how you avoid replacing it again next month.
Chafe is the leading cause by a distance. A line rubbing on a frame member, on another hose, or against a moving part wears its cover away, then its reinforcement, and then it lets go. The giveaway is a flat, polished patch exactly where the burst is. If you fit a new hose along the same path without adding a clamp, a sleeve or a different route, you have bought yourself the same failure on a schedule.
Age and heat do the rest. Rubber hardens over years, cracks in its cover, and loses flexibility until a bend that used to be fine starts to split. Hose run near an exhaust or a hot engine component ages faster. Then there is the abused end: a line that has been yanked, twisted at installation, or run at too tight a bend radius carries damage from day one. Hose should never be installed with a twist, because pressure in a twisted line works the fitting loose.
If one line let go from chafe or age, the ones bundled next to it have had the same life. Look before you leave.

Keeping dirt out of an open circuit
Every hose replacement opens a hydraulic system that was designed to stay sealed, usually outdoors, frequently in dust or mud. Hydraulic components fail from contamination more than from anything else, and the particles that do the damage are far too small to see. A pump does not care that the grit arrived during a five minute hose change.
The habits that prevent it are simple and they take almost no extra time. Ports get capped the moment the old line comes off. Fitting faces are wiped before assembly rather than after. New hose gets blown clean, because assemblies can carry debris from cutting and crimping. Fluid comes from a sealed container, not from a part used jug that has been riding open in a truck bed collecting dust.
After assembly the circuit gets cycled and checked. Air trapped in a system makes a function feel spongy and jerky, so the machine is worked gently through its range to purge it and bring the fluid up to temperature. The reservoir gets topped to the correct level, and the joints are checked again under pressure, because a fitting that is dry at idle can weep under real load. Only then is the machine actually finished.
Lines we build and the machines they go on
Hose work turns up everywhere, not only on equipment. Anything that lifts, tips, steers or brakes with fluid eventually needs a line replaced.
Excavator hose failures
Boom, stick and bucket circuits, thumb and coupler lines, and the runs along the boom that chafe where they are clamped.
Loader and skid steer lines
Lift and tilt circuits plus auxiliary lines to attachments, which take abuse from quick couplers being connected in the dirt.
Dump truck and trailer hoists
Hoist circuits that fail loaded, which is both a downtime problem and a safety one until the body is supported and the pressure is off.
Power steering and brake lines
Hydraulic assist circuits on trucks and equipment, where a leak affects control rather than only productivity.
Agricultural and vineyard equipment
Tractors, implements and sprayers around the valley, where a line usually gives out at the least convenient point of the season.
Everything else on the machine
If the hose was a symptom of something larger, the same visit covers the pump, valve or cylinder behind it.
What happens between the call and the machine running
A single hose is usually a same visit repair. Here is the order it goes in, so you know what to expect while we are on site.
- Safe shutdownAttachments lowered, engine off, stored pressure relieved. A circuit can hold pressure long after the machine is switched off.
- Remove and readThe old line comes off and gets inspected. Where it failed and why decides whether routing needs changing.
- Identify and buildEnds identified by type rather than by eye, length taken from the original, hose rated to the circuit, then crimped on the truck.
- Fit and routeInstalled without twist, at the right bend radius, clamped and sleeved where it needs protecting from what killed the last one.
- Fill, purge and testReservoir topped, air cycled out, joints checked under load. The machine leaves running properly, not just reassembled.
Common questions about hose work
Oil on the ground is a call worth making now. Somebody picks up at any hour.
Can you make a new hose at my location?
Yes. The truck carries hose stock, a fitting assortment and a crimper, so the replacement line gets built next to the machine rather than ordered from a counter. That is the whole point of doing this work mobile. Unusual sizes, very high pressure flange work or specialty assemblies occasionally have to be sourced, and you will hear that on the phone.
Should I keep using the machine if a hose is only weeping?
Not for long. A weep means the joint or the hose is already failing, and hydraulic pressure does not get gentler over time. A seeping line usually becomes a burst line under the heaviest load of the day, which is both the worst moment and the messiest. It is also a slip and fire hazard once oil is on the machine and the ground.
How do you know which fitting my machine uses?
By identifying it properly rather than by matching a thread. JIC, ORFS, NPT, BSPP, flange styles and metric variants overlap closely in size while sealing in completely different ways. We identify the seat and the seal type on the old end, which is why the failed hose is worth keeping rather than cutting off and discarding before we arrive.
Will you check the other hoses while you are there?
Yes, and it is the most useful part of the visit. Lines bundled together have the same age, heat exposure and rubbing history, so when one goes the others are often close behind. We look at covers, clamps and rub points and tell you what is worth doing now versus what will hold for a while, then you decide.
Do you work on trucks and trailers too, or only equipment?
Both. Dump hoists, trailer circuits, power steering and hydraulic assist lines on commercial trucks all get the same treatment as equipment. A loaded dump body with a failed hoist line gets handled carefully, because the body has to be supported before anybody works underneath it.
What does a hose call cost?
You hear one number covering the visit and the line before we head out, and no hourly minimum gets applied to a short job. If the hose turns out to be a symptom of a failing pump or cylinder, we tell you what we found and what that repair involves before doing anything beyond the hose you called about.
Oil on the ground? Call now.
A hose is one of the fastest repairs we do, and one of the worst to leave sitting. Tell us the machine and roughly where the line runs, and you will have a number and an arrival time before the call is over.
