Rings are easy to work down over a piston into their respective
positons without any tools if your only doing a piston or two on
occassion. If I was in the business of overhauling engines I would
invest in a ring expandcer for installing rings as well as a ring
com[ressor for compressing them around the piston so you can slip them
in their cylinders.......As to ring gap, each and evey spec engine has
its own ring gap. Ring gapa is the space between the rings whrn the
ring is in the cylinder. Its necessary to have the correct gap for
retaings sufficient sealing area for compression and sufficient space
to keep them from expanding when hot and possibly scrubbing and
breaking...so check your manual for what the ring gap is. Install or
place a ring in the cylinder without it being installe don a piston,
and measure gap between rings ends......to small a gap, just file it a
b it to get the proper gap measurement..If its too large check to make
sure you have proper rings, or perhaps your cylinder is worn so it
needs reboring and fitting of next size piston and rings.........

One other little trick nobody's mentioned.

When you check the gap, you need to have the ring in the cylinder absolutely
square. The easy way to do it is to put the ring into the cylinder and then
push it down a little using a piston (sans rings) as a tool. That way, your
measurement of the gap (with a feeler guage) will be accurate.
