Hydraulic Repair in Midland, TX

Hydraulic hose, cylinder, pump, and valve repair at Chris’s Diesel Service in Midland. Hoses are built and crimped here in the shop or on site from the service truck, cylinders are resealed and rods repaired in house, and pumps are rebuilt instead of automatically replaced. Every diagnosis starts with pressure and flow numbers, so the repair lands on the component that is actually worn.

What We Repair

Hose to Pump. The Whole Circuit.

Hydraulic failures rarely stay where they started. A failed pump seeds the whole system with metal, and a rubbing hose takes out more than the hose. We repair the component and treat the circuit, on every machine that comes through heavy equipment repair.

01

Hydraulic Hose and Line Repair

Hoses built and crimped to spec, either in the shop or on site from the service truck. Blown lines, the chronic weeper at a fitting, and rub points that keep eating the same hose. We carry hose stock, fittings, and a crimper on the truck, so most field hose calls are built and back in service on the first visit. Custom routing and bracket work is handled through our welding and fabrication shop.

Crimped to Spec Built On Site

02

Hydraulic Cylinder Repair

Resealing, rod repair and polishing, piston and gland work, and barrel honing on lift, tilt, boom, ram, and stabilizer cylinders. Drift is measured against spec before and after, so you know the reseal actually fixed it. Cylinder work makes up a large share of what comes through on excavator repair and bulldozer repair.

Reseal and Rod Work Drift Verified

03

Pump and Motor Rebuild

Gear, vane, and piston pumps, hydrostatic drive pumps, and swing and travel motors. Condemned by pressure and flow numbers, rebuilt or replaced based on what teardown shows, and the failure cause corrected so the new unit survives. The same circuits drive boom and lift functions on telehandler repair.

Flow Tested Rebuilt In House

04

Valves and Controls

Control valves, relief valves, holding valves, and pilot circuits. Reliefs are set to machine spec with a gauge, not by ear. Sticking spools and erratic functions get traced to the valve itself or to the pilot signal feeding it, which are two very different repairs at two very different prices. When the signal is the problem it moves over to diagnostics and electrical.

05

Jacks, Lifts, and Dump Bed Hoists

Hydraulic jacks, lift cylinders, tailgate lifts, and dump bed hoists, along with the pumps and valves behind them. These show up constantly on work trucks and trailers, and they are a regular item on fleet services accounts where one truck sitting still backs up the whole week.

06

Oil, Filtration, and Contamination Flush

Oil and filter service, full system flushes after a failure, and the contamination control that keeps the replacement part alive. Dust is a constant in West Texas and hydraulic systems do not forgive it. Skipping the flush is how shops end up selling the same customer two pumps in a year.

System Flush Clean Oil Discipline

How It Works

Measure. Repair. Flush. Verify.

Half of hydraulic repair is the component. The other half is making sure the system does not kill its replacement.

01

Test the Circuit

Pressures and flows measured against machine spec, oil condition inspected, and the failing component identified by numbers. You get an itemized written quote before any repair begins.
02

Repair and Decontaminate

The component rebuilt or replaced with OEM standard parts, and the system flushed when a failure shed debris. Hoses are built to length and routed clear of the rub point that killed the last one.
03

Verify Under Load

Pressures rechecked hot, cycle times confirmed, reliefs set with a gauge, and the machine worked under load before release. Proven, not assumed.

Mobile Hose Service

Hoses Built Where the Machine Sits.

Chris and his team run a service truck that carries hose stock, fittings, and a crimper, so a blown line gets measured, built, and installed where the machine sits instead of getting trailered in and losing you a day. Heavier field work, including cylinder removal with the crane, runs through mobile heavy equipment repair, and anything needing a full teardown comes back to the shop.

Hoses Built in the Field Stock hose and fittings ride on the truck. Most field hose calls are measured, crimped, installed, and cycled in a single visit.
Over the Counter at the Shop Bring the old hose in and we match length, fittings, and pressure rating at the Midland counter while you wait.
Midland and Odessa Coverage Hose calls run roughly 100 miles out from Midland, which covers Odessa and most of the working Permian Basin.
Routed Clear of the Rub Point The replacement gets routed away from whatever killed the last one. A hose that fails twice in the same spot is a routing problem, not a hose problem.

Standards and Capability

Hydraulics Reward Discipline. And Punish Shortcuts.

A hydraulic system does not forgive dirty oil, misrouted hoses, or reliefs set by feel. Every rule below exists because we have seen what happens when somebody skips it.

Numbers or Nothing No component is condemned without pressure and flow evidence. A relief valve out of adjustment mimics a dying pump, and the price difference is enormous.
Rebuilt, Not Just Swapped Cylinders are resealed and rods repaired in house. Pumps and motors are torn down and rebuilt when the internals justify it, so you are not paying for a new unit every time.
Cleanliness Standard Capped lines, clean fill, filtered transfer, and system flushes after failures. Contamination control is the cheapest reliability money buys.
All Equipment Types Dozers, excavators, loaders, telehandlers, cranes, work trucks, trailers, and oilfield equipment. If it moves oil under pressure, it is in scope.

Hydraulics FAQ

Common Questions

Can you make hydraulic hoses on site?

Yes. The service truck carries hose stock, fittings, and a crimper, so we measure, build, and install the hose right where the machine sits. We also build hoses over the counter at the shop in Midland if you would rather bring the old one in and match it. Either way the hose is crimped to spec and routed clear of whatever was rubbing it.

How do you know if a hydraulic pump is actually bad?

By measuring it. Flow at rated pressure tells you the pump’s condition, and case drain flow tells you how much it is bypassing internally. Weak functions are just as often a relief valve, a suction restriction, or low oil. We test before we condemn, because a pump is expensive and a gauge reading is not.

Do you rebuild hydraulic cylinders or only replace them?

We rebuild them here. That covers resealing, rod repair and polishing, piston and gland work, and barrel honing. Replacement happens when the barrel or rod is past saving, and we tell you which one you are looking at after teardown rather than quoting a new cylinder up front.

Why does my equipment lose hydraulic power when it gets hot?

Heat thins the oil, and thin oil slips past worn clearances that seal fine cold. A system that fades in the afternoon usually has a worn pump or motor, degraded oil, or a cooler that cannot keep up. We test hot, because that is when the problem exists.

My pump failed. Do I really need a system flush?

If the pump shed metal, yes. That debris is sitting in the valves, cylinders, coolers, and lines, waiting to destroy the new pump. A flush costs a fraction of a second pump replacement. We have seen too many repeat failures from skipped flushes to leave this optional.

Do you repair hydraulic jacks and dump bed hoists?

Yes. Jacks, lift cylinders, tailgate lifts, and dump bed hoists all come through, along with the pumps and valves that run them. Most of this work is on trucks and trailers rather than heavy equipment, and a lot of it can be handled in the field.

Do you travel to Odessa for hydraulic repair?

Yes. The service truck runs across roughly 100 miles of Midland, which covers Odessa and most of the working Permian Basin. Hose work, cylinder removal, and diagnostics are all done at the job site. Work that needs a teardown comes back to the shop.

What does hydraulic repair cost in Midland, TX?

It ranges from a single hose to a full pump rebuild and flush, which is why we test before we quote. You get an itemized written estimate after diagnosis and before any work begins. Testing first regularly saves customers from buying pumps their machines did not need. Call (432) 557-6500.

Weak, Slow, or Leaking?

Get the circuit tested before you buy the expensive part. Hoses built on site, cylinders and pumps rebuilt in house, and pressures verified hot before the machine goes back to work.
