Heavy Equipment Repair in Los Angeles
Around Los Angeles, aggregate yards, recycling operations, earthmovers and heavy civil fleets run machines that are too big for ordinary shops — and too valuable to leave waiting on dealer lead times. Top Notch Equipment Repair repairs and rebuilds heavy equipment at our Fontana shop and serves LA with free pick-up and delivery: hydraulic pumps and cylinders, engines, transmissions, final drives and undercarriage, all backed by in-house machining and gear manufacturing.

Big iron is our home ground
Wheel loaders, full-size excavators, dozers, articulated haulers, scrapers and heavy support equipment — Caterpillar, Komatsu, Volvo, John Deere, Hitachi and more. A component worn past what a seal kit can cure gets rebuilt or remanufactured, and a failed gear can be cut new. That depth is exactly why heavy fleets ship machines out to Fontana.

Our repair process, in eight steps
Every job — large or small — travels the same eight stages, from the opening call to a tested unit back in service.
Inspection
We strip the unit down and judge the failure as a whole, not just the obvious part.
Photos & video
Findings and condition are captured in photos and video to keep the discussion straightforward.
Repair quote
The work we recommend is spelled out and priced in writing before we proceed.
Approval
We agree the scope, how pressing it is, and the practical route from here.
Manufacturing
Required parts are machined, welded, rebuilt or reverse engineered on site.
Testing
Before release, we confirm the unit works as it should and the work is up to standard.
Shipment
The completed equipment or component is returned, ready for service again.
