Ingersoll Rand Gearbox Repair in Fontana
When a Ingersoll Rand gearbox starts making noise, running hot or shedding metal into its oil, the machine behind it is living on borrowed time. We rebuild Ingersoll Rand gearboxes working in compressor, hoist and industrial air-tool drives across manufacturing plants 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 Ingersoll Rand gearboxes wear — and what we do about it
The Ingersoll Rand units that reach our bench most often show high-speed pinion scoring, compressor-drive bearing fatigue, and oil starvation damage on units run past their service interval. 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 repair the gearbox on an Ingersoll Rand compressor drive?
Yes — high-speed pinions are measured for scoring and profile wear, bearings renewed as a set, and lubrication passages verified clear before the drive is run-tested.
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.
Do you offer rush gearbox repair?
Yes — 24-hour rush and emergency service runs every day of the year. Call (800) 821-3404 or (949) 400-2937.
