Four Systems. One Shop.

Wheel loaders are half truck, half hydraulic machine, and this shop repairs both halves. Four areas of work, one accountable name, backed by the wider heavy equipment repair bay.

01

Drivetrain and Axles

Powershift and hydrostatic transmission repair, torque converters, driveshafts, differentials, and planetary axle ends. Weak drive and slipping ranges diagnosed by pressure testing and road-tested loaded before release.

Powershift Axle Ends
02

Loader Arm Hydraulics

Lift and tilt cylinders resealed or repaired, main and pilot valves serviced, and weak breakout force traced to the pump, relief, or cylinder actually causing it. Bucket and linkage pins built up where wear has stacked. Circuit work runs alongside our hydraulic repair bench.

Cylinders Pins and Bushings
03

Engine and Cooling

Diesel engine diagnostics, repair, and full in-house rebuilds by Chris and his team. Cooling packs cleaned and repaired for West Texas summers, fuel systems serviced, and emissions faults handled with live data.

In-House Rebuilds Live Data
04

Electrical and Controls

Starting and charging systems, harness and connector repair, transmission control faults, and gauge problems traced through diagnostics and electrical. Official Continental Batteries dealer, so the honest fix is often on the shelf.

Controls Batteries

Tested. Repaired. Proven Loaded.

A wheel loader that limps back for the same failure twice costs more than the repair ever did. The process prevents the second trip.

  1. 01

    Diagnose by Testing

    Transmission and hydraulic pressures, engine data, and electrical checks measured against spec. The failure is identified by evidence, and you get an itemized written quote first.

  2. 02

    Repair It Right

    OEM parts when they exist, best available standard when they do not. Related wear flagged honestly while the machine is open, with no upsell to work it does not need.

  3. 03

    Prove It Under Load

    Drive, lift, and tilt worked under load, temps and pressures confirmed, and the machine checked out by Chris before it goes back to the pile.

Built for Machines That Load for a Living.

A down wheel loader stops material moving for the whole operation. The shop, the crane truck, and the welding bay exist so that stop is short and does not repeat, whether the machine works in Midland, Odessa, or out across the Permian Basin.

  • Full-Size Shop Access 140 x 150 ft facility with the door height and floor space to bring wheel loaders inside for teardown work.
  • Field Capable An 8,000 lb crane service truck covers a 100-mile radius through mobile heavy equipment repair when hauling the machine does not make sense.
  • Welding In-House Bucket cracks, cutting edges, wear plates, and pin bore buildup handled through welding and fabrication in the same building as the mechanical repair.
  • Compact Machines Too Smaller machines have their own dedicated service. See skid steer repair for hydrostatic drives, tracks, and quick attach work.

Common Questions

What wheel loader problems do you repair?
The full machine: powershift and hydrostatic drivetrains, axles and differentials, loader arm hydraulics, engines including in-house rebuilds, cooling, and electrical. If the machine digs, lifts, or drives wrong, it is in scope. Call (432) 557-6500 with the make and model.
Which wheel loader brands do you repair?
Our team works on CAT, John Deere, Case, Komatsu, Volvo, and Hyundai wheel loaders, along with other makes running Permian Basin sites. Powershift and hydrostatic drivetrains differ between manufacturers, but the diagnostic method does not. Call (432) 557-6500 with the make, model, and what the machine is doing.
Why is my wheel loader losing power or slipping in gear?
Usually the transmission clutch packs, the torque converter, or low pressure from a tired charge pump, and sometimes just a plugged filter or low oil. We pressure-test the transmission against spec before condemning anything, because the cheap cause and the expensive cause share symptoms.
Can you repair a cracked wheel loader bucket?
Yes. Bucket cracks, cutting edges, wear plates, and worn pin bores are handled by our in-house welding bay, with the stress point gusseted so the crack does not return. Mechanical and welding work happen in the same building on one ticket.
Do you service wheel loaders on site?
Yes. The service truck carries an 8,000 lb crane and covers a 100-mile radius around Midland, which reaches Odessa and most working Permian Basin locations. Hoses, cylinders, batteries, and many component swaps happen at your location. Transmission teardown and other clean-environment work comes back to the shop, and we tell you which upfront.
What does wheel loader repair cost in Midland, TX?
It depends on what testing finds, and that is why we test first. A relief adjustment and a transmission rebuild are very different jobs. You get an itemized written estimate after diagnosis and before any work begins, with honest run-it versus fix-it advice.
