Sumitomo 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.
