Should be floating pins, was easy to do with a 20r I rebuilt.
From the FSM
"At 80 C (176 F), you should be able to push the pin into the piston with your thumb
If the pin can be installed at a lower temperature, replace it and the piston"
With the 20r, I think I just tapped it in........ (didn't feel lose, and with circlips I didn't worry about it)
