2012 KOP Fisher price with AM Planetary Gearbox

[Bob Ward]

We had a gearbox on the AM-0822 lock up the other day. It was on our ball launcher and had just been powered down, but was still coasting at high speed. All of a sudden it just seized up completely.

Opening the gearbox revealed one of the 5 planetary gears totally fused to its shaft. It can't be turned or removed by hand. The only thing I can think of is that it was installed dry. The other 4 are fine.

I would strongly recommend that you open the boxes and make sure each planetary is well-lubricated. We didn't and paid the price.

Waiting to hear from Andy Mark.

Has anyone else run into this problem?
