Can you please send a picture? The photos that get a hydraulic repair quoted right

We ask for a picture because a hydraulic quote lives in details a phone call loses: the thread on a fitting, the size printed on a hose, the shine on a cylinder rod. Two or three clear photos texted from the field usually mean the truck arrives with the right hose or seal kit already on it, and the first number you hear is the number you pay.

It is the most common text we send back after a call around Longmont, and it can read like a brush off when a baler is down with hay on the ground. It is the opposite. A mobile hose repair truck carries hundreds of fitting ends and several hose sizes, and the picture decides which ones get crimped before leaving. On a cylinder, the picture decides whether it is a same visit reseal or a bench job, which is the difference between $350 and $3,000. Here is what we are looking at, and how to take the shots without getting hurt.

Why do you need a picture before you can give me a price?

Because the price is set by the parts, and the parts are set by things almost nobody can read off over the phone. A hydraulic hose is defined by its inside diameter, its pressure rating, the length between fittings, and the two end fittings, and the end fittings alone come in a dozen thread families that look alike to anyone who does not handle them daily. A JIC 37 degree flare and an O ring face seal thread onto different ports and will not seal on the wrong one. On older farm equipment, a 1970s swather or a loader that has been rehosed twice, the fittings on the machine may not match what the parts book says. The photo settles it in ten seconds.

On a cylinder the question is the rod. A rod that is smooth and bright with oil weeping at the gland is a seal kit and an hour. A rod with a score you can catch a fingernail on will cut new seals in weeks, and it has to come off for bench work. The field or shop article covers that split in detail. We can quote the reseal range on the phone, but a picture of the rod is how we avoid quoting a reseal and finding a rebuild.

What pictures should I send for a hydraulic hose or cylinder repair?

Six shots, and you rarely need all six. For a hose, the two fittings and the layline matter most. For a cylinder, the rod and the data plate. The wide shot helps on every call.

The leak itself, engine offHose burst versus fitting weep versus cylinder gland seepHose call or cylinder call, and whether the oil is still in the machine

Any data plate or part numberOEM part numbers on the cylinder, pump, or valve bodySeal kit or replacement part pulled from stock before rolling

A few habits make the photos useful. Wipe the fitting or the rod with a rag first, because a film of oil and dust hides threads and scoring. Get close enough that the fitting fills a third of the frame, then take one step back for a second shot that shows where it sits on the machine. If the hose has a layline, turn it so the printing faces the camera. Daylight beats a phone flash on chrome. And if you can lay a tape measure or a coin next to the fitting, the size question is answered.

How do I take the picture safely with the machine leaking?

Shut the machine off and lower every implement to the ground before you get close, and never put a hand near a leak to feel for it. Farm and construction hydraulics run at 1,000 to 3,000 psi, and a pinhole stream at that pressure goes through skin and gloves. Ohio State University Extension’s hydraulic system safety fact sheet spells out that a fluid injection injury needs a doctor immediately even when it looks like a pinprick, and that lines stay pressurized after the engine stops until the pressure is bled off. A raised loader bucket or a boom is stored energy, and it will come down when the hose lets go.

  1. Lower everything. Bucket, boom, header, blade on the ground. Then key off.
  2. Wait a minute. Let the spray stop and the puddle settle before approaching.
  3. Photograph from arm’s length. Zoom instead of leaning in over a fitting.
  4. Use cardboard, not fingers, if you need to find where a pinhole is coming from.
  5. Do not restart it to show us the leak. A video of it spraying costs oil and risks the pump. The still photo of the wet spot is enough.

What if I cannot send a picture?

Call and describe it, and the truck still rolls. No cell signal on the Little Thompson bottoms, a flip phone, or a hand you would rather not take off the tractor: all three happen every week. On the phone we ask for the make and model, which hose or cylinder (left lift, right tilt, boom, bucket, header lift), roughly how long the hose is, and whether the oil is dripping, running, or spraying. That is enough to pull the likely sizes and the seal kit, and the on site diagnosis covers the rest. The service call is the same published number either way, $95 in Longmont, Hygiene and Mead and $125 to $165 across the rest of the coverage, Berthoud included. What the picture buys you is the first trip being the only trip.

Every machine is different, and a photo narrows a range, it does not replace eyes on the fitting. Text the shots to (970) 528-6741 or send them with the form below, and you get a range for your machine and your ground before the truck leaves. The published table is on the pricing page.

Machine, the leak, both fittings or the rod. We text back what it looks like and what it runs before anyone drives.

We can take 5 more scheduled fleet inspections this month. Breakdown calls always get worked in.
