Ohio Gearbox Repair in Fontana
When a Ohio gearbox starts making noise, running hot or shedding metal into its oil, the machine behind it is living on borrowed time. We rebuild Ohio gearboxes working in industrial gear drives in conveyors, mixers and general plant machinery at our Fontana shop at 14166 Whittram Ave — strip and measure every gear, shaft and bearing, manufacture what can no longer be bought, and return a box that runs to specification. Everything is done under one roof by the crew that quoted the job, with no work farmed out and no parts swapped on guesswork.

How Ohio gearboxes wear — and what we do about it
The Ohio units that reach our bench most often show general-duty tooth wear from years of conveyor service, mixer-drive seal leakage, and bearing wear on units that outlived several motors. At teardown we record backlash, tooth contact patterns, bearing condition, shaft wear and housing bore condition before anything is quoted — then we renew what the measurements condemn: bearings and seals as a set, shafts restored or made new, and gears cut in-house when the original is worn past saving or discontinued. Backlash and preload are set to specification and the finished box is run-checked before it leaves Fontana.

Frequently asked questions
Can you still get parts for an older Ohio gear drive?
In most cases we do not need to — worn gears, shafts and wear parts are measured and manufactured in-house, with bearings and seals renewed as standard, so age alone does not scrap the drive.
What are the warning signs a gearbox needs attention?
New noise under load, rising operating temperature, metal in the oil, leaking seals and growing backlash are the usual warnings — catching them early is the difference between a bearing-and-seal renewal and a full gear replacement.
