On my 
Judge Dredd the plant gearbox seems to move slower than other ones I see in online videos. It takes some online videos I have seen about 8-9 seconds for a ball to go all the way around, mine takes about 13 seconds. The motor seems to consistently move the planet however it sounds like it's struggling at times. Here
is a 1-minute video from under the playfield, you can hear it slow down a few times, notably at 45 seconds in
(its easier to listen a few seconds before). I have never gotten to play another Dredd so any perspective would be super helpful.
