This tool is cheap at most auto parts stores.
It hooks both ends of the ring and spreads it apart making the inside diameter wider than the piston.
Then lift the ring off / on the piston.
Caution: only spread the ring just enough to remove / install it.
Used on top and second rings.
(the bottom oil rings are usually removed by hand)

| A wooden spacer with slot to hold piston steady as you slide the cylinders on. Also, a Volkswagen “krinkle cut” ring compressor that comes apart after the cylinder is on. The crinkle cuts stop it from jamming up in between the piston and cylinder. Also, use plenty of oil in the rings, piston and cylinder to help it all slide on. 2) |
