Versa Planetary Issues

[roystur44]

Check your load ratings using the JVN motor calc and figure out the actual load using a luggage scale.

You might need to add another motor to load your catapult.

The 2014 motor mounts work way better than last years model. Don't put a excessive amount of grease into the housing.

We are using a dual motor input using two 18 Volt RS-775's, 3 stages at 300:1 with the 18:84 final reduction. The winch setup works great. Winds the choo choo around 8 seconds and can pull down with over 200 lbs.

I'm not 100% sure but i believe the 2014 models, besides having different motor mounts, fixed the binding issue by removing the unnecsary 3rd bearing that holds the motor shaft coupler in place. By not having the 3rd bearing it avoids any binding from slight misalignment in the assembly. If you are still using a 2013 model, it may help to remove this bearing by pushing it out of the housing, removing the clip holding it in place with the shaft coupler, and seperating it from the shaft coupler. Then reasamble without the bearing. It may help with binding issues.

Check to see if the pins on the planet plate protrude above the tops of the planet gears. On some of ours, they were, which caused binding. I fixed the issue by pressing them back down. I can't speak to whether they'll loosen again over time, though.

That was the problem. We had a spare plate from a planetary that blew up a couple weeks ago (oops) so I just used that. Thanks everyone for input.
