When I had mine apart years ago, I couldn't get the damn liners to 
move!  Had to make a puller to get them out!

The sealant doesn't stretch.

Lemme suggest another idea, without any real idea of whether or not 
it would actually work:  With the other 11 liners firmly retained, 
turn the crank and ENCOURAGE that liner to come up with the piston, 
making sure the piston doesn't go back down WITHOUT the liner (once 
the rings clear the bottom of the liner, I think you'd be in trouble 
indeed).  With the piston at the TOP of its stroke but at the BOTTOM 
of the liner, the liner should be raised by the 70mm stroke with no 
problem.  Simply clean off the old sealant under the lip on the 
outside of the liner, apply new sealant, and push the thing back 
down.  Might even repeat for the other 11, since this one seemed to 
move too easily.  Leaks around the liners mean the coolant leaks into 
the crankcase, not good.

Anxious to hear discussion on this idea, and suspect that Johnson 
would be well advised to listen to feedback before actually trying 
it.
