Hey Guys,,,a bit of an update on the Miller welder/Onan engine. Bruce got it on the money as far as separating the engine from welder. I got em apart and opened both cylinders, and the dang rings were stuck to the pistons. Took some of my ultra secret ATF/Acetone mix and doused em good and let em set. At about that time I had to make an emergency trip to ER to take my wife that was having "chest Pains",,,,She had a stroke last August and we feared the worst. They kept her overnight for observation and determined she was suffering from extreme stress.,,,Got her home next day and she's and resting well.
I was messing with the pistons and she asked me what I was trying to do,,,,Duh????? She said,,,,,"why don't you boil em in hot water to remove the
rust that was caused by the
water[b][/b]"? WHAT,,,??? Well, you know the rest of the story, don't you?? I boiled em just to humor her,,and after a couple of hours,,,I tapped on the backs of the compression rings and both the top rings popped out pretty as you please. The oil rings did the same but only got one of the middle compression rings loose this way. Who'ed a thunk??? Have we discovered something new here?
Any way,,,I got a question for the group... This place has rings in STD and .010 OS. My cylinders mik'ed out to 3.257
and 3.256 on a factory 3.250 bore. Can I file fit the .010 rings to recommended end gap of .010 (min) and .020 (max),,or are they a tad too big for this bore? OR,,,go with the 3.250 STD rings?
