Gear Reducer Repair

Gear Reducer Repair

Gear reducer repair across every frame and ratio — worm, helical, bevel-helical, planetary, shaft-mount and gearmotor.

Gear Reducer Repair — what it covers

Gear reducer repair is the highest-volume work in the shop network, and the most predictable. A reducer that whines, leaks, runs hot or backlashes usually needs bearings, seals and an inspection — not a new unit at a five-month lead time. Rebuilt reducers ship in 8–12 business days at 30–60% of new cost.

We rebuild every major reducer line: SEW-Eurodrive R, K, F and S series, NORD SK, Sumitomo Cyclo and Paramax, Dodge Torque-Arm, Quantis and Maxum, Boston Gear 700 and 800 series, Falk Y and Quadrive, Flender H2SH and Motox, Winsmith, Cone Drive, Bonfiglioli, Motovario, Rossi, Brevini, Hansen and dozens of obsolete builders.

Standard gear reducer repair scope: teardown and solvent clean, gear tooth inspection against AGMA tolerance, shaft runout and spline wear check, complete bearing and seal replacement, housing bore inspection, breather and vent service, repaint, then a run test for noise and temperature before shipping.

Where a rebuild does not pencil out — small frames where new units are cheap and available — we say so and quote a replacement instead. You get all three numbers, repair, replacement and cash offer, before any work starts.

Gear Reducer Repair questions

How much does gear reducer repair cost?
Small reducers commonly run $800–3,500; mid-size industrial reducers $3,500–15,000; large planetary and mill reducers considerably more. A rebuild generally lands at 30–60% of new-unit price, and we publish the replacement number beside it so the comparison is honest. Call (641) 519-6270 for a free teardown quote — or sell us the unit as-is for cash.
Is it worth repairing a gear reducer or should I replace it?
It depends on frame size and availability. Below roughly 5 HP, new units are often cheap and in stock, so replacement wins. Above that — and on any obsolete or long-lead unit — a rebuild is usually both faster and materially cheaper. We give you both numbers rather than steering you. Call (641) 519-6270 for a free teardown quote — or sell us the unit as-is for cash.
Can you repair a gear reducer with a cracked housing?
Usually yes. Cast iron housings are weldable and bores can be line-bored back to spec. A cracked housing is only a write-off when the crack runs through a bearing seat in a way that cannot be restored to tolerance. Call (641) 519-6270 for a free teardown quote — or sell us the unit as-is for cash.
How fast can a gear reducer repair ship?
8–12 business days standard, 24–72 hours on emergency service with free rush freight both directions. Call (641) 519-6270 for a free teardown quote — or sell us the unit as-is for cash.
