Gear Repair in San Bernardino
San Bernardino's rail yards, aggregate plants, distribution centers and Cajon Pass fleets all turn on gears — transmissions and final drives in trucks and loaders, gearboxes driving conveyors, crushers, mixers and pumps, and differentials that climb the pass loaded every day. When a gear fails here, it rarely fails politely: chipped teeth shed metal through the whole box, and worn mesh patterns whine for months before they let go. LA Trucks and Tractors serves San Bernardino from our Fontana gear shop at 14166 Whittram Ave, a short run west on I-10, where gears are inspected, measured and — when the original is discontinued or destroyed — cut new in-house to the sample or the drawing. The city's working gear list is wider than vehicles: recycling and materials plants, food and beverage production, water and wastewater machinery, and the aggregate operations toward the foothills all drive through gearboxes that cannot be replaced off a shelf. Those industrial boxes get the same bench, the same measurements and the same manufacturing backup as a truck transmission — because in San Bernardino, both kinds of downtime cost money by the hour.

Gear cutting and gearbox rebuilding under one Fontana roof
A gearbox tells the truth at teardown: tooth contact patterns show misalignment, pitting shows overload or starved lubrication, and bearing wear shows in the backlash numbers. We read all of it before quoting. San Bernardino gear work covers spur, helical, bevel, hypoid and worm gearing across transmissions, differentials, final drives and industrial boxes — shafts measured and renewed, housings checked, bearings and seals replaced, mesh and backlash set to specification, and the finished box run-tested before it leaves. Where a replacement gear no longer exists from the manufacturer, our own gear manufacturing keeps a sound machine or production line out of the scrap conversation entirely. Lubrication failure is the cause we find most, and we say so on the quote when we find it: a rebuilt box returned to a starved oil supply or a breather plugged with plant dust is a repeat failure with a date on it, so oil condition, filtration and cooling are checked and reported alongside the mechanical findings. Customers get the mesh readings, the backlash and end-play numbers, and a straight statement of what was renewed, what was reused within specification and what to watch — the record a maintenance department or an owner-operator actually needs.

Gear Repair in San Bernardino · San Bernardino, CACounty-seat fleets, pass-climbing trucks, one gear bench
Pick-up and delivery are free between San Bernardino and Fontana, and the rush line runs 24 hours a day, 365 days a year — a dead gearbox on a production line or a pass-route truck is an emergency by any honest definition. Regular hours are Monday-Friday 6 AM-5 PM, quotes are free and written from teardown measurements, and you deal directly with John Clark. Our shop is in Fontana only; San Bernardino gear work is served from there, and we state that plainly rather than dressing up a service area as a second location. Gear work also pairs with the rest of our benches when a failure has spread: a transmission that shed metal has usually fed its cooler and lines, and a final drive that ran dry has stressed its axle bearings, so the whole cleanup is handled in one visit instead of returning a clean box to a contaminated machine. One call, one teardown, one tested assembly back on the road or the line — that is the whole proposition for San Bernardino gear work.
