Excavator Repair in Fontana · Fontana, CAFull reconditioning & repaint
Cat M322F Wheeled Excavator — Reconditioned & Repainted
This Cat M322F wheeled excavator came in rough and road-worn. Our crew masked it off, prepped every panel and laid down fresh Cat yellow right here in our Fontana yard — then loaded it out looking like a new machine. It is the same full reconditioning work we do on excavators and heavy equipment: body, paint, decals and detail, start to finish.

Free pick-up and delivery when applicable; Monday–Friday 6 AM–5 PM, and a 24-hour rush line every day of the year.

Frequently asked questions
Which excavator brands do you repair?
Caterpillar, Komatsu, Hitachi, Kobelco, Volvo, John Deere, Case and more — brand pages detail each line. The hydraulic bench does not care about the badge.
My excavator is slow and weak on one side — what is it?
One-sided weakness usually points to a travel motor, final drive or a pump section feeding that side. We pressure- and flow-test and show you the readings.
Do you do undercarriage work?
Yes — tracks, rollers, idlers, sprockets and tension systems, plus the final drives behind them.
