Why repair your 100C with us
Real numbers before teardown
Most shops quote only after your unit is in pieces on their bench. We publish the whole market — new, used, scrap, competitor repair — up front, so you negotiate from strength.
Cheaper and faster
Our network rate beats standard shop pricing by roughly 18–25% on the 100C, with turnaround 2–3 days shorter — and 24–72 hour emergency rush when the line is down.
Two-way market maker
If repair isn't the smart move we say so, buy your unit for cash, and can supply a tested used replacement. No other gear shop gives you all three exits.
20+ years of industrial iron
Industrial Surplus World has bought, sold, and rebuilt Philadelphia Gear equipment for decades — refineries, power drives are daily work, not an experiment.
About the Philadelphia Gear 100C
The Philadelphia Gear 100C is a custom parallel-shaft drive from the Custom parallel/right-angle, marine drives, 100C line, rated to 2,000 hp across ratios of customer spec, and most commonly found on refineries, power. Philadelphia Gear (Timken Power Systems) built the heavy custom gearboxes in US Navy ships, power plants, and refineries — legacy units still running after 50+ years.
When a 100C fails, the real decision is economic: a new unit lists at $30,000–$88,000 with a 16–30 week factory queue, a tested used unit trades at $12,000–$63,400 when you can find one, and a standard shop rebuild runs $13,800–$52,800 over 8–16 weeks. Our in-house network rate of $10,800–$43,300 in 4–10 weeks beats all of those paths on total cost of downtime — and if the unit is beyond economic repair, its scrap weight alone is worth $576–$1,408, while we'll pay $1,440–$15,200 for the core as-is.
Typical failure modes on this family are bearing wear, shaft-seal leakage, and tooth-surface distress from degraded or contaminated oil. A correct rebuild means full teardown, hot-tank cleaning, magnetic-particle inspection of all gearing, verification of bearing-bore tolerances, all-new bearings, seals, shims and gaskets, reassembly to factory clearances, and a loaded run-test with warranty up to 24 months. Done right, it restores full service life at a fraction of replacement cost.
