Remark :
Due to limited stock availability, please notice that some Kyosho items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

How should I check gear mesh after installing the UM734?

Set a light and even mesh by using shims or adjusting gearbox positioning as required, then rotate the drivetrain by hand to confirm smooth, silent engagement before running.

What maintenance routines keep the gearbox reliable?

Regularly inspect gears, bearings and seals for wear, clean debris from housings and replace worn parts promptly to maintain consistent shifting and longevity.

Will changing gear ratios still work with this gearbox?

You can experiment with pinion and spur choices to alter final drive behaviour, but any ratio change should be tested carefully to ensure gears and motor operate within safe limits.

Is professional fitting recommended?

Experienced hobbyists can fit the UM734 using standard tools, but those unsure about setup or mesh may prefer a dealer or experienced technician to ensure optimal installation.

What signs indicate the gearbox needs service?

Listen for unusual noises, check for increased play in gear engagement and watch for overheating. Any of these signs suggest inspection and possible parts replacement.
