Why repair your CNHM-6165Y 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 CNHM-6165Y, 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 Sumitomo equipment for decades — crushers, agitators drives are daily work, not an experiment.

About the Sumitomo CNHM-6165Y

The Sumitomo CNHM-6165Y is a cyclo 6000 cycloidal gearmotor from the Cyclo 6000, Paramax 9000, Hansen P4 line, rated 10–40 hp across ratios of 6:1–119:1, and most commonly found on crushers, agitators. Sumitomo Drive Technologies' Cyclo cycloidal reducers (6000 series), Paramax parallel-shaft units, and Hansen heritage lines carry 500% shock-load ratings and dominate mixers, conveyors, and crushers.

When a CNHM-6165Y fails, the real decision is economic: a new unit lists at $2,800–$7,200 with a 16–30 week factory queue, a tested used unit trades at $1,120–$5,200 when you can find one, and a standard shop rebuild runs $1,290–$4,300 over 10–15 business days. Our in-house network rate of $1,010–$3,500 in 8–12 business days beats all of those paths on total cost of downtime — and if the unit is beyond economic repair, its scrap weight alone is worth $38–$94, while we'll pay $130–$1,250 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.

CNHM-6165Y questions

What does vibration on a Sumitomo Cyclo mean?
Cycloidal drives have unique vibration signatures — Sumitomo's own analysis shows high-frequency peaks with sidebands typically mean ring-gear rollers or the eccentric bearing are distressed, not the input bearings everyone replaces first. A proper teardown reads the wear pattern. Call (641) 519-6270 for a free teardown quote — or sell us the unit as-is for cash.
Sumitomo Cyclo is 40 years old — can anyone still fix it?
Yes — Cyclo 6000-series internals are remarkably standardized, and we rebuild every vintage. The 500% shock rating means the housings almost never die; discs, rollers, and bearings do, and those are all replaceable. Call (641) 519-6270 for a free teardown quote — or sell us the unit as-is for cash.
How much does gear repair cost compared to buying new?
A quality rebuild typically runs 30-60% of new-unit cost — and skips the 16-30 week factory lead time on industrial units. Small ancillary boxes run $1,000-5,000; heavy mill and oilfield gearboxes $10,000-100,000+. We publish both numbers plus a cash offer for your unit as-is. Call (641) 519-6270 for a free teardown quote — or sell us the unit as-is for cash.
How fast can you turn a repair around?
Standard rebuilds ship in 8-12 business days — typically 2-3 days faster than standard shops — and 24-72 hour emergency service is available with free rush freight both directions. Call (641) 519-6270 for a free teardown quote — or sell us the unit as-is for cash.
