Wheel loader repair · Fontana, CA

Wheel Loader Repair in Fontana

Every aggregate yard, batch plant, and recycling operation in the Inland Empire lives or dies by its wheel loader — and those machines put in punishing hours. Our Fontana shop repairs articulated loaders of every size and make: lift and steering hydraulics, transmissions and torque converters, axles and differentials, engines, and the pins and bushings that high-hour machines consume. Cylinders are rebuilt and machining is done in-house, and gear work is the trade this shop was founded on.

Loader jobs that come through weekly

Rebuilds for lift and tilt cylinders. Work on steering cylinders and articulation joints. Servicing for hydraulic pumps and valves. Diagnosis and rebuilding of transmissions and converters. Axle and differential repairs, with gears cut in-house when the job calls for it. Engine repairs. And renewal of center pivots, pins, and bushings, with line boring where it is needed. When a loader stops, the plant stops — everyone in this shop understands that.

Questions we hear often

What loader makes do you repair?

Caterpillar, Komatsu, Volvo, John Deere, Case, Kawasaki, and more — between the hydraulic bench, the transmission bench, and the machine shop, the full range is covered.

Can loader cylinders be rebuilt here?

They can — resealing, new rods, honing, and gland machining all happen in-house, including the big cylinders fitted to production loaders.

Do you take on articulation joints and center pivots?

We do — pins, bushings, and line-boring across articulation and linkage points are everyday machine-shop work here.
