Gear & Gearbox Repair in San Jose
Beyond the tech campuses, San Jose still runs aggregate plants, recyclers, food processors and big logistics operations — and their conveyors, crushers and mixers all live or die by their gearboxes. When the work stops in San Jose, the schedule behind it does not — so neither do we. LA Trucks and Tractors serves San Jose as a service area from our Fontana shop at 14166 Whittram Ave, Fontana, CA 92335, with transport to our shop, mobile and onsite assessment where the job allows, and a full rebuild shop behind it. We do not have a shop in San Jose — San Jose work is served from Fontana, and we state that plainly on every quote.

Full-shop gear & gearbox repair for San Jose
San Jose gearboxes show two kinds of wear: crusher and conveyor shock fatigue in the industrial districts, and continuous-duty tooth and bearing wear in plants that run three shifts to keep up with valley growth. Because the machining, gear cutting, cylinder bench, pump shop and motor work are all in-house in Fontana, a San Jose job gets one teardown, one measured quote and one accountable rebuild — gearboxes are stripped and measured, worn gears cut new in-house when they are discontinued, bearings and seals renewed as a set, and backlash reset to specification. Nothing is farmed out and nothing is guessed at: every line on the quote comes from something we measured at teardown.
