    Like fleetwin says, I wouldn’t use any kind of ring compressor on them as it would be to easy to snap an end off if the ring isn’t lined up perfectly with the locating pin. I like to install them one ring at a time. Once the bottom ring is in the hole, the next ring is put on the piston and so on until all three are in.
