[Fot] Snap Rings in Pistons

[fubog1]

 It's likely that you'll find a rounded/radiused-cut groove in the piston to accomodate the round clip, a square-section substitute circlip won't seat properly.A tiny screwdriver & some patience will do the job but yeah they suck!

I have seen a ton of retaining rings in my life but those take the dumb cake.  I would recommend measuring the needed size and order them from McMaster Carr.  Even if you install those the next person will need to bugger up the pistons to get them out!

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.
I am assembling a Ford 1600 CC engine for my Morgan and have bought new pistons.  The snap rings that came with these pistons do not have the holes in the ends.  See attached picture.
These snap rings are very stiff and I can't squeeze them in by hand.  I also can't figure out a way to grip them with the snap ring pliers I have.  Does anyone know if there is a special tool I need to use to install these?  Or any suggestions about how I should go about installing them?  Thanks.
