      Has anyone got a simple method of getting the piston with rings on into the bore of a cylinder. these are 1 1/2 inch diameter? I managed in the end but the air was blue, I haven’t enough fingers for the job.

          I haven’t tried it on pistons and rings that size but when I used to mess around with old cars and motor bikes there was a thin steel cylindrical device available which could be tightened around the piston and rings enough to hold the rings in place but enabling the piston to slide, enabling the piston to be fed in , ring by ring so as to speak. Shouldn’t be too difficult to knock one up.

            A sliced up baked bean tin and a Jubilee Clip would be the makings of a piston ring compressor for me.

              I use what mick described for my motorbikes – known as a piston ring clamp. Basically a slit steel cylinder which is narrower than the bore when closed together. Put it over the pistons with the rings on, everything is nipped up nice and tight. Lower or raise the cylinder into the bore. Once the closest ring approaches the bore, loosen the clamp and raise it up but keeping the overall circumference just narrower than the bore. As the piston ring enters the bore it will be kept secure as it goes in further. Just continue the process of introducing the piston into the bore, loosening the clamp and moving it up/dpwn the piston.
               
              Main thing to note is that the clamp never enters the bore – it’s only there to keep the rings compressed to get them inside the bore as the piston is introduced into the bore. Hope I’ve explained this enough.

                Oh btw, I sympathise with the language. Doing it my first time on a 4 cylinder 550cc engine with four pistons to get into their respective bores with 3 rings on each was fun. I got a piston ring clamp pretty soon after that !

                  Hi
                  Hope this helps first go onto ebay search piston ring clamps they are very cheap or look at pics copy and make one for yourself they mostly involve a jubelee clip.
                  Thats what I done with my 7.25 train the pistons with clupit rings.
                   
                  good luck
                  Bob
