I've used this ring compressor successfully in a variety of bore sizes for many years, though in the 'olden days' I wasn't too far away from a coupla thin strips of plastic or ice cream sticks set opposite one another to ease the piston & rings into the bore.

I've successfully used thin plastic (food containers/ ice cream) or cut down food /drink cans in conjunction large worm drive hose clips  with plenty of lubrication.

Too complicated for me. I'll stick with two screwdrivers and a pair of thumbnails.

I've used a hose clamp with success on several R series motors. The wide ones just cover all 3 rings.

cheers guys , all good suggestions

the problem im having is locating the pinned rings whilst clamping up the device .a progressive clamp process will let me do that , instead of a clamp designed for minimum of 75mm  (the pistons are about 66mm )

ill get the right thing ,in time

meanwhile, all silicon coated surfaces have been cleaned up and ready for a new reassembly .

one lives in hope ....

I tip my cap to you sir! You patience, attention to detail, and persistence is unbelievable.

I have never bin deep inside a brick engine. Are the piston rings pinned or have any crazy orientation being a horizontal stroke?
