The slide ring can be easily removed by hand.

is installed in a groove in the
cylinder head inside wall. To remove, thrust a sharp-
tipped tool into the buffer ring, pull out the ring from the
groove to allow insertion of a pry bar under the ring and
pry the ring out with a pry bar.
Note:
Discard the removed seals.
9. Remove the U-ring, back up ring and wiper ring.
Remove the U-ring and back up ring with a screwdriver.
To remove the press-fitted wiper ring, pull it out after
