How it works

Describe the failureTell us what failed — blown hose, leaking cylinder, pump noise, or PTO issue. Include equipment type and hose sizes if known.
Mechanic dispatchedWe send a hydraulics specialist with mobile crimping equipment and common hose/fitting inventory.
Diagnose and repairYour mechanic assesses the system, fabricates hoses on-site if needed, and completes the repair at your location.
System testedHydraulic system is pressurized, tested for leaks, and cycled to verify full operation before sign-off.

A blown hose shouldn't shut down your operation.

Hydraulic failures happen fast and stop work instantly. Whether it's a blown hose on a dump truck, a leaking cylinder on a refuse truck, or a pump failure on a concrete mixer, our mechanics make and install hydraulic hoses on-site and repair hydraulic systems in the field.

  • Hydraulic hose fabrication

    On-site hydraulic hose fabrication using mobile crimping equipment. Hoses are built to fit on the spot when the mechanic has the right fittings.

  • Cylinder repair

    Hydraulic cylinder seal replacement, rod repair, barrel honing, and complete cylinder rebuild for dump bodies, liftgates, and outriggers.

  • Pump and motor service

    Hydraulic pump testing, replacement, and motor service for all types of mobile hydraulic systems including gear, vane, and piston pumps.

  • PTO and wet kit repair

    PTO engagement issues, wet kit installation and repair, hydraulic tank service, and control valve troubleshooting.

  • Hydraulic leak repair

    Systematic leak detection and repair across the entire hydraulic circuit — hoses, fittings, cylinders, valves, and reservoir.

  • Fluid service and filtration

    Hydraulic fluid replacement, filter changes, contamination flushing, and fluid analysis to prevent premature component wear.

Questions

No estimates. The mechanic diagnoses, quotes, and you approve before any work.

Yes, when the mechanic has a mobile crimper and the right hose and fittings. Tell dispatch the hose size and equipment so they send a mechanic who can build it at your location.

We service hydraulic systems on dump trucks, refuse trucks, concrete mixers, rolloff trucks, liftgate-equipped vehicles, bucket trucks, cranes, and other commercial hydraulic equipment.

We don't promise a time before a mechanic accepts. When one does, you see a live arrival time on your status page. Phoenix dispatch works 7 AM to 7 PM Arizona time, every day.

Yes. We install, repair, and troubleshoot PTO-driven hydraulic systems including wet kits, pump/tank/valve assemblies, and PTO engagement mechanisms.
