the carousel has a basic fault inside the gear.
The first gear inside the gearbox will break after
short time of running. I will replace the plastic gear
by a gear of brass.
You have to dissassemble the carousel from the top.
You remove the top. You will see a screw.
At the lower part of the roof you see 4 snap-ins.
After doing the 4 snap-ins you can remove the
upper roof. You unsold the 2 wires of the wipers.
Yo open the hexagonal screw and the you can
remove the whole mechanics.
