New motors for the diecast Oliver Dozer!
Here is a very short Timelapse video of the first test with the new motors.

I broke another one of the economy gear motors in the Dozer at cabin fever this year so the plan was to try the planetary gear version. I had the Dozer on the bench since January and FINALLY got around to installing the new motors.
I had to make a bushing/sleeve for the new motors because they are just a tiny bit smaller diameter and didn't fit into the existing motor mounts, so got those made on the lathe.
Another problem I had with this project was with the sabertooth motor controller. I finally added capacitors to the motors and that solved it, BUT, as I installed the new motors I decided to try powering the new motors WITHOUT the caps and so far the seem to operate with less electrical noise and I didn't have the same trouble! So, if you are using the economy gear motors from servo city I would recommend adding capacitors to control the interference noise that causes problems for the sabertooth. And, the motor can of the new planetary motors looks different and I suspec it is a little better quality motor. Time will tell...
For those interested here is a link to the old spur gear motors and another link to the new planetary motors at Servocity.

And I have a question about these motors for you tech type guys-
As I post the links I expected to see a higher torque vale for the planetary motors but that is not what I read? Is this based on the motor more than the gear style and ratio?
