Gear Repair in Riverside
Riverside plants, aggregate operations, food processors and municipal facilities run gearboxes that were installed decades ago and are expected to keep running — conveyors, mixers, pumps and drives whose manufacturers have moved on. LA Trucks and Tractors serves Riverside from our Fontana gear shop at 14166 Whittram Ave, where gearboxes are torn down, measured and rebuilt in-house and worn gearing is reverse-engineered and manufactured on our own machines when no replacement exists on a shelf.

Rebuild the gearbox you own — including its obsolete gears
A gearbox failure is usually a gearing, bearing and clearance story told in order. We document tooth wear, backlash, bearing fits, shaft and housing-bore condition at teardown, then quote from those measurements. Gears worn past limits are measured for their original geometry — module, pressure angle, helix and center distance — and cut new in-house, so a Riverside drive keeps its original housing, footprint and ratio instead of forcing a plant re-engineering project around a substitute unit.

Yes — that is core work for our gear shop. We measure the worn original, work out its geometry, and manufacture a replacement matched to the drive's ratio and center distance.
Do you repair truck and equipment gearboxes as well as industrial drives?
Yes. Industrial gearboxes, truck transmissions and differentials, and equipment final drives are all rebuilt on the same benches at our Fontana shop serving Riverside.
