Gear & Gearbox Repair in Oakland
Oakland's terminals, aggregate plants, recyclers and manufacturers drive everything through gearboxes — crane drives, conveyor boxes and mixer gearing that take port-city punishment daily. When the work stops in Oakland, the schedule behind it does not — so neither do we. LA Trucks and Tractors serves Oakland 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 Oakland — Oakland work is served from Fontana, and we state that plainly on every quote.

Full-shop gear & gearbox repair for Oakland
Gearboxes serving Oakland industry show tooth fatigue from shock-loaded conveyor and crane duty, bearing wear from years of vibration, and seal leakage wherever harbor moisture gets in. Because the machining, gear cutting, cylinder bench, pump shop and motor work are all in-house in Fontana, a Oakland 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.
