Yes, the rounded groove for the retaining clip is why I used the round wire
clip from Wiseco. It was one I could find that was the same thickness as the
original factory clips. But this design, without an easy way to grab it, is
for pistons that have a recess that allows a tool to get behind the clip just
enough to remove it.
In my case, this will most likely be the last service for these pistons, so
damage to them during the next disassembly won't be a problem.

I am trying to install the snap rings which hold the wrist (gudgeon?)
pins in the pistons. The snap rings I have used on the TR-3/4 engines and
most of the other engines I have rebuilt, have small holes in the ends.
These allow you to insert snap ring pliers into the holes so you can squeeze
the snap rings into place in the grooves in the piston bores.

These snap rings are very stiff and I can't squeeze them in by

to install these? Or any suggestions about how I should go about
installing them? Thanks.
