Gearbox Repair for Pharmaceutical Plants in Fontana
Pharmaceutical production runs on drives that cannot improvise: high-shear mixers, granulators, tablet-press drives, coaters and packaging lines across the Inland Empire and Southern California. When one of those gearboxes wears, LA Trucks and Tractors rebuilds it at our Fontana shop at 14166 Whittram Ave — measured teardown, in-house gear manufacturing for discontinued parts, and a run-checked return, with the documentation discipline a regulated plant expects.

How pharmaceutical plant gearboxes wear — and what we do about it
Plant drives that reach our bench most often show mixer gear fatigue from batch shock loads, seal leakage where washdown and cleaning chemistry reach the housing, and bearing wear on packaging drives that run three shifts. At teardown we record backlash, contact patterns, bearing condition and shaft wear before anything is quoted — then renew bearings and seals as a set, restore shafts, and cut replacement gears in-house when the original is discontinued. Backlash and preload are set to specification and the finished box is run-checked before it leaves Fontana.
