Reading a failed hydraulic hose, and what the fix costs on site
Burst, abrasion and fitting leaks each look different, come from different causes, and carry a different price.
Call (920) 521-8455Oshkosh Hydraulic Line Repair replaces a lot of hoses, and almost every one failed for a reason you can see. The reason matters. A hose that burst from a pressure spike will burst again if the relief valve is stuck. A hose that rubbed through on a bracket will rub through again unless the routing changes. Before the old hose goes in the scrap bucket, look at it.
Burst: the hose let go all at once
A burst hose is the failure everyone recognizes. Fluid on the ground, sometimes on the ceiling, and a loader arm that dropped. A split along the length, a few inches from either end, usually means the hose was worked past its rating or aged out. Two wire hose on a loader lives outside for a decade and one cold morning with a full bucket is enough.
A burst right at the crimp points somewhere else. Either the crimp was wrong for the hose (wrong die, or one brand's fitting on another brand's hose) or the hose was bent too tight coming out of the fitting. Rusty wire at the split means water got under the cover long ago. Either way the hose is replaced, never patched, and a tight bend gets a longer route.
Abrasion: the cover rubbed away first
Abrasion is slower and easier to miss. Run your hand along the hose (machine off) and feel for a flat, shiny patch. That is where the cover rubbed on a frame rail, another hose, a bracket edge or a tire. Once the cover is gone the braid shows bright, then rusts, then strands break, then the hose weeps and fails. On a skid steer boom you can often find three hoses in a bundle all worn at the same spot.
The replacement is priced from the same table, but the routing gets fixed at the same time or you buy the same hose again next season. That means a spiral guard over the rub point, a clamp that holds the hose off the rail, or a different length, and it is what "hose routing that needs guards" means on the price table.
Fitting leak: wet, dirty and slow
A fitting leak looks like a fitting caked in dirt, because dust sticks to the oil film. Wipe it, run the machine, and watch for a drip at the nut. Four common reasons, and only the first is fixed with a wrench.
- Never fully seated. A JIC nut left a quarter turn short weeps under pressure. Snug it once. If it still weeps, stop.
- Damaged O ring. ORFS and O ring boss ports seal on a rubber ring. One nicked on install, cooked by heat or flattened by age lets fluid past no matter how tight the nut is.
- Cracked or galled seat. A 37 degree flare overtightened or tightened with grit in it gets a scored seat and weeps forever.
- Wrong thread mated. JIC, ORFS, pipe thread and metric look alike at a parts counter. Some pairs thread together and never seal.
If the leak is at the port and the hose end is sound, the fix is a fitting, adapter or O ring swap with the hose reused. If the weep is where the hose meets the ferrule, the hose is remade.
What each fix costs at the machine
| Failure | Usual fix | On site price |
|---|---|---|
| Burst or worn two wire hose, 1/4 in to 1/2 in | New assembly made on the truck | $150 to $300 |
| Burst or worn four or six wire hose, 3/4 in to 1 in | New assembly, flange or tube ends | $250 to $500 |
| Fitting leak at the port | Fitting, adapter or O ring, hose reused | $90 to $180 |
| Service call, Oshkosh, Neenah, Menasha, Omro | Added to any of the above | $75 to $125 |
| Service call, Fox Valley and lakeshore towns (Appleton, Fond du Lac, Winneconne, Ripon) | Added to any of the above | $95 to $175 |
Labor inside those ranges is $95 to $140 per hour. After hours the call is $150 to $250 and labor is 1.5 times the day rate, on the emergency page. Every row is on the pricing page.
So a burst loader hose in Oshkosh during the day is usually $225 to $425 all in, and a weeping fitting on the same machine is usually under $300 with the call. That gap is the reason to look at the fitting the week it starts collecting dust.
What not to do while you wait
- Do not feel for the leak with your hand. Fluid at working pressure goes through skin, and the result is a hospital visit. OSHA calls it an injection injury.
- Do not wrap it and keep running. Tape and clamps do not hold hydraulic pressure.
- Do not run the reservoir dry. A pump that has been pulling air costs more than any hose on this site.
- If fluid reached a ditch, a drain or the lake, note how much. Wisconsin DNR has reporting thresholds and we tell you honestly whether it needs a call.
What to send before you call
A photo of the failure and of both ends, texted to (920) 521-8455, plus the machine, the town and a rough length. That is enough to quote inside the range and arrive with the right hose the first time.
If this is the second hose this season, the preseason inspection at $120 to $250 per machine finds the rest before they pick their own time. The winter fluid guide covers the other half of a Wisconsin cold season.
Hose failure questions
How do I know if a hydraulic hose burst or just wore through?
- A burst hose splits along its length or blows open at the crimp with the wire pushed outward. A worn hose has a flat, polished patch where the cover rubbed away and the wire went bright, then rusty, then let go.
Can a leaking fitting be tightened instead of replaced?
- Sometimes, once. A JIC fitting that was never fully seated can be snugged and it will hold. One that leaks after it has already been tightened has a damaged seat, a cracked flare or a mismatched thread, and more torque makes it worse. A fitting or O ring swap runs $90 to $180 with the hose reused.
What does it cost to replace one hydraulic hose on site near Oshkosh?
- A single two wire hose made and fitted at the machine is $150 to $300. Add the service call, $75 to $125 in Oshkosh, Neenah, Menasha and Omro, and a typical daytime job lands at $225 to $425 all in.
Should I keep running the machine with a small leak until you get there?
- No. A weep becomes a spray under load, a spray at pressure goes through skin, and a reservoir that runs dry takes the pump with it. Shut it down, block anything held up by that circuit, and send a photo. If it is a slow drip and the machine can finish the hour, we say so on the phone.
