Question about legality of motor "modification"

so as a part of the preparations for the upcoming season we were considering replacing the bearings inside of our falcons with newer bearings. some concerns were brought up about this being against R502, so I went and checked. thing is, I don’t know if this falls under “Repairs, provided the performance and specifications are unchanged”. we’re not changing the motor specs in any way, since the new bearings are exactly the same as the old ones. just…new. however, the bearings aren’t broken yet, so this might not count as “repairing”.
what do you think? is this legal?

If it’s the same spec as the official bearing and won’t improve performance beyond its factory-fresh capabilities, then I’d assume it’s probably legal. I’d wait for a robot inspector’s confirmation though (there are plenty active on CD).

When I asked “Have you modified any of your motors”, if I got a yes response instead of the usual automatic no, I would ask for clarification. If I was then told that the repair was solely replacing bearings I would check the OK box and move on.

I would probably mention it to the LRI at some point if I remembered to do so.

All of this assumes I hadn’t been instructed otherwise in advance.

If you told me you used the frictionless bearings they taught us about in school, I would ask where I could get some.

If you hit the old bearings with a hammer, then they are broken. Hence it’s a repair.

In reality, I think you are good. If your intent is to just replace “used” bearings to prevent potential unseen damage or wear, I think this is totally find. I’d consider replacing a wore component repair.

Now if you found some ultra low friction bearings or something, then that would be an illegal modification since you are trying to improve performance.
