So my RP3 failed after some use and curious about how it works, I decided to disassemble it. To my dismay the unit was made to prevent dismantling it, much less repair it.

The kinematics are sealed in the stainless steel housing by means of a lip that is roll formed or pressed in at the bottom. I had to turn it down in order to remove it.

After turning down the lip I had to make a sleeve to knock the internal plastic out of the steel housing. If anyone is curious or wants to try it, here's the dimensions, which by the way I had to find by "turn" and error because it wasn't possible to measure it with a caliper. Renishaw really made it a point to make it a PITA to peak inside.

This is how it looks with the lip removed.

Also made a mini clamp out of aluminum to hold the housing down like so:

Inserting yet another special made sleeve with 3 slots cut out at 120° apart from the top and knocking that damn thing out.

Moment of truth... This is how it looks inside:
