I’ve got a very worn pair of SS Nano Techs I would like to overhaul.

Is there a tool/adapter that you can screw in to inject grease?

Are the bearings replaceable? Where do you get the 9mm (guessing @ 9mm) very thin walled socket from?

BITD when the first M737 SPDs arrived and the plastic collars invariably stripped we used to just drill a 1.5mm hole in the outside of the body and inject grease in that way forcing out the old grease.

I can get the grease in, I was wondering if someone had come up with an easier way than removing plug, fill plug with grease screw on, repeat 100 times.

Errrrr…….drill a hole in the plug?!
