Why is my Sumitomo Engine running hot?

  Lydia MedinaAug 3, 2025
  Your Sumitomo Engine may be running hot due to several reasons. It could be overloaded, exceeding the reducer's rated capacity. The lubricant level could be improper, either too low or too high, or the wrong type of lubricant might be in use. Check the rated capacity of the reducer, replace with unit of sufficient capacity or reduce the load. Check lubricant level and increase or reduce to recommended levels. Flush old lubricant and refill with the correct recommended lubricant.

  Jessica KingAug 7, 2025
  If your Sumitomo Engine has oil leakage, it could be due to worn seals, leakage into the motor, a clogged air breather, or improper mounting. Replace the oil seals and clean or replace the breather filter, being careful not to let any dirt fall into the reducer. Check the lubricant level and adjust to the recommended level. Ensure the unit is mounted at its designed mounting angle.

Why is my Sumitomo Cyclo Helical Buddybox Engine vibrating or making noise?

  Victoria ToddAug 12, 2025
  Excessive vibration or noise in your Sumitomo Engine can stem from several issues: loose foundation or hold-down bolts, worn disc and/or helical gearing, bearing failure, insufficient lubricant, or damaged Cyclo® pins and rollers. Inspect the mounting and tighten any loose bolts, reinforcing the mounting if necessary. Check lubricant level and adjust to factory-recommended level. If helical gearset is damaged or output bearings are damaged, contact the factory. If Cycloid discs are damaged, disassemble the Cyclo® portion and replace discs. If bearings in Cyclo® portion are damaged, replace the affected bearings and flush the reducer, refilling with the correct lubricant. Disassemble Cyclo® portion of reducer and replace ring gear housing pins and rollers. Check load on reducer.

What to do if the output shaft/hub of my Sumitomo Cyclo Helical Buddybox Engine does not turn?
- J
  Jennifer KingAug 17, 2025
  If the output shaft/hub of your Sumitomo Engine isn't turning, the motor shaft might be broken, the input shaft key could be missing or broken, or the eccentric bearing may be broken. Replace the broken shaft or key. Replace the Eccentric Bearing in the Cyclo® portion, then flush and refill the unit with the recommended lubricant. Check rated capacity of reducer.

What to do if the Sumitomo Engine rotates when the load is disconnected but when the load is connected?
- J
  Jodi Phillips DVMAug 23, 2025
  When the load is connected to Sumitomo Engine, the switch may overheat, there may be an overload, the fuse may blow, the engine overheats, there is a voltage drop, the speed suddenly drops, or the engine stops. Replace the switch or fuse with one having the rated capacity. Decrease load to the rated level. Consult with local power company. Replace the bearings.

What to do if the load is disconnected but motor of Sumitomo Cyclo Helical Buddybox does not rotate?

  Mary KennedyAug 27, 2025
  If the load is disconnected from your Sumitomo Engine but the motor does not rotate, it could be due to a faulty switch contact, a blown fuse, an open phase wire in the power supply, an open stator coil, or the stator and rotor touching due to bearing housing wear. Adjust the contact, replace the fuse, or replace the phase wire. Repair the stator by rewinding or replacing the stator assembly. Replace the bearing and bracket.
