It pretty frustrating all right -
I made a tool from a screwdriver.
Get a good quality screwdriver with a tempered blade, the type that has
tapered shoulders, not the type where the blade is the same width as the
shaft, about 7 inches long overall, and has a tip about 1/8" wide at the
end.
File the sides of the flats to an angle like so a cross section through the
blade looks like this.

/-----------\
Next you will have to file the tip to a size where the tip will only just go
into the gap in the end of the snap ring.
The next bit is a bit hard to describe, but by wriggling, pushing, twisting
and a few naughty words you will be able to ease one end of the ring out of
the groove, and pull it back with something. I have another screwdriver that
has an edge filed to form a hook, I use this to ease the ring back away from
its groove.
If the snap rings have undercut ends, this method works readily. I
understand that there are replacement snap rings from Moss that have square
ends. I have heard that this method will work with them as well, but with
some difficulty. I would advise replacing the rings if they get a bit
mangled by the removal process, and perhaps if they are the square ended
type, they could be undercut a bit with a touch of grinding. This will save
you from being called a *&#@(DPO at some future date. A 4" angle grinder
with a cut off wheel would be narrow enough to go through the opening in a
new ring. Clamp the grinder in a vise or similar, and just touch the inside
square end of the ring to put a 45 deg champher on each end. Clean up any
burrs with carborundum paper. .
If my description of the filing up of the screwdrivers is not the best,
email me and I will send a sketch direct.
