[QUOTE="Tom Gaynor, post: 14397, member: 4034"] I tried shim stock, and hose clamps but eventually went back to basics. I didn't have, and was unable to find a bike ring compressor. First you MUST have a chamfer inside the liner. It doesn't have to be huge, but it HAS to be there. Fit the gasket, but if using Wellseal or the like, leave the top of the gasket clean for now. Then, prop the piston in place with a couple of bits of wood placed either side of the rod on top of the crankcase. That makes the job MUCH easier. A refinement is to put some torque on the crank to keep the piston in contact with your two bits of 1" x 1/2" strip. Slide the barrel down over the piston canting it slightly to "catch" the front of the top ring then the rear.. I chose to have all the ring gaps on the side I was working from so I could push any "loose ends" in to the ring groove with a screwdriver without the acrobatics required to change sides. Then apply Wellseal to the top of the gasket, if using, and drop the barrel into place. I've done Vincents, Rudges and Manx Nortons all the same way. Use makes master..and I've never broken a ring.
