Do not expand the piston rings any more than is necessary to allow them to be
removed from the piston. The rings are brittle and will break if expanded too much.
Prior to removing the rings, check the ring-to-groove clearance of each compression
ring (see Piston Ring to Groove - Clearance).
The top and second compression rings are different and are not interchangeable (see
Piston - Assembly).
Piston rings must be removed from the piston using hand pressure only. Do not
overextend the piston rings during removal.
If the piston rings are to be reused, note the orientation of the oil control rings prior to
removal.
If the piston rings are to be reused, keep them with their respective piston to make
sure they are refitted in their original locations.
1. Ease the top compression ring out of its groove and remove it from the top of the
piston.
2. Remove the second compression ring in the same way.
3. Remove the oil control rings and expanders.
