Hello Henri123160

Often dust is in the gears.

You can also turn the motor with your hand, then you might notice a resistance at a certain point. There could be something with the gears

Make all that belongs to the gear and clean all visible deposits of fat and oil thoroughly and then lubricate all bearings and all screws sparingly. The teeth of gears made of plastic, brass and bronze, which are not part of worm gears, remain und lubricated. Steel wheels are lubricated, but there are no steel wheels in there.

What kind of engine did Arnold installed? Is there a way to wait collector and coal? If so, clean the collector of deposits and check if the coals and their feathers are still in order.
