What you need for conversion set
- The model and upgrade kit
- Small flat screwdriver
- Soldering iron 15W/25W
- Super glue or Loctite
A torch, a self made pin and bracket to remove the worm. More info here.
Installation time: Around 1/2 hour
Remove screw on top of the model in the chimney.
Remove original motor
Remove two screws on the bottom of the model (on this picture the new motor has already been installed). Then solder the wires of the new motor to the contact strips and screw the new motor in place.
Place brass adapter in worm
Remove the worm from the original motor (do not use the Tramfabriek gear puller here, as most of the time, the worm is fitted too tight and you will break the pin. You’ll need to heat it up with a torch. For more valuable tips how to remove a worm, gear or flywheel, click here. If you find it difficult, just send the motor to me and I’ll take the worm off. You are even welcome to do this before purchase, so we’ll send it out with the kit.
Then press the brass adapter in the original worm. Be careful with the adapter, the wall is only 0.1 mm thick. You might have to clean out the worm to make room for the adapter.
Check how far the worm has to go on the motor axle, glue it if necessary on the axle. It might already fit well in place with pressure fit. Use Loctite and not Superglue, as with Superglue you will not have time enough to adjust the height.
Glue the motor in place. I used the gel version of superglue. Just sparsely some gel around the edge of the motor opening on the frame will do the job. Check if the worm touches the gear, but not so that it locks the gear. You need to be able to wiggle the rear wheels a bit. If you get a crunchy noise when running the model, the worm is too close.
