[SEL] Stuck Piston Rings

[Rob Skinner]

Hi, Ed.  Get yourself a brass drift, start at one end, and tap the  
rings IN.  Tap a couple times, rotate the piston a few degrees, and  
tap the ring again.  Keep going around and around and around.   
Eventually you'll notice a little movement.  Keep working your way  
around.

When you notice one area is loose and an adjacent area is still stuck,  
don't tap too hard on the loose area, or you'll break something.  Just  
be patient and keep tapping.  Eventually the ring will come loose all  
the way around.
