I came across a Youtube video the other day about pedal maintenance. I’ve never done anything with my Powertap P1 pedals other than to replace batteries and keep them clean. The Powertap site says there isn’t anything user serviceable. However, I did come across a second pedal video which seems to state otherwise. My concern would be compromising the calibration so I am really skeptical.
I figured if anyone knew about PowerTap maintenance they’d be on this site.
Here is the 2nd video in question:

If its not broken, leave well alone. I am a Nuclear Engineer for 40 years, seen so many times people tinker with stuff and a little knowledge and it ends up needing replaced. You can service the bearings from what i have seen, but the bearings can be tight to remove but if you have too and after 5 years old you have had your monies worth. LBS worth considering if you want back in one piece
The pedal bearings on my P1 pedals needed maintenance about a year ago. I debated the same as you but ended up sending them in to them for servicing and just paying the money rather than messing with it myself.
I don’t regret the decision because if I get another 3-4 years out of the bearings it’ll be money well spent
