Common faults and what to check first
Noise or rough running
Often worn bearings or low or contaminated lubricant. Do not keep running a noisy gearbox.
Oil leak
Usually a worn seal or a damaged shaft surface. Stop the leak before the gearbox runs dry.
Backlash or positioning error
Wear in the gear train or a loose coupling. Check the coupling first, then the gearhead.
Gearbox overheats
Check oil level, ventilation and load, then the bearings.

Frequently asked questions
Do you repair servo gearheads?
Yes, we repair planetary and other gearheads used with servo motors: bearings, seals, lubrication and a backlash check. Send the nameplate photo and the fault.
Can you repair the motor and the gearbox together?
Yes. If a servo gearmotor fails, send it as one unit. We check the motor and the gearbox and report on both.
Will backlash be restored to new condition?
It depends on wear. We measure it and tell you what can be corrected and what needs replacement parts.
Do you repair worm and helical industrial gearboxes?
Yes, for common faults such as bearings, seals and lubrication. Send the nameplate and the fault and we confirm.
Can you repair an obsolete gearbox?
Often, where bearings and seals can be sourced. Send the nameplate photo.
What should I send?
The gearbox, the nameplate photo, the fault and the machine type. Use the checklist on this page.
How long does repair take?
Timing depends on the fault and parts. Send the nameplate photo first and we confirm timing before you ship.
