[Fot] Snap Rings in Pistons

[Chuck WATSON]

Yes, push the side of the ring that is 180 degrees from the opening in with a screwdriver or something small with a notch. Once inserted, rotate into place.

Thanks,

Chuck Watson

I've been able to use a small thin screwdriver to work them in.  Put the end in the wrist pin hole and angle the blade to compress the ring.  Hard to describe.  I go as far as I can by hand and then use the screwdriver to get more leverage.  There's got to be a special purpose tool too.

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.
