582 cylinder replacement

[egp8111 7]

curiosity got the best of me wondering if my 582 with 27hrs.TT was a boat anchor after being stored for 8 yrs, so I started taking it apart to have a peek inside. One thing lead to another and soon I had the cylinders off. Good news all the needle bearing looked good on the conrod bearings etc. I'm going to send it off to be serviced by a Rotax expert but I need to get the cylinders back on. I read the Rotax manual etc. but I can get the cylinders back on past the lower piston ring. Is there a trick here or is it just me ! thanks

Are you aligning the ring with the stay pin in the ring gruve?

Both ring gruves have a pin to keep the ring from turning.
