I heated my cylinders up in the oven (when my wife wasn't home) and they dropped right out. I put the new sleeve in the freezer, and it dropped into the warm block without much force.

today's observations... less than .003 clearance but..

Post by barnbiketom » Wed Feb 22, 2017 11:32 am

the remaining 3 circlips are oriented in all different positions. one the gap is up, one the gap is right, one is left... NOt GOOD.. supposed to be down ? right???

there appear to be TWO different sets of rings.
on the RT side, the blown side, only one ring has a marking.. the second ring ...it has a tiny "N" and a TINY step on the bottom of the ring..

the left side, no rings have markings but the middle ring has a much different profile than the one on the right.. a much bigger step in the bottom side...and it was stuck from varnish/gookum.

heres some pics of the piston the clip came out of...it does have a circlip escape pathnow that i soda blasted off the varnish!! , I can barely catch my fingernail on it!!

I didn't realize that sleeves fell out when heated. I "thought" that they had to be pressed in.

I just heat the barrel up with it inverted on blocks. The liners just drop out. Reverse is also true. Just heat up and they drop in. The machine shop I use recommends that you push them down with a press after the barrel has cooled.
