hey all,

i cant seem to be able to remove the sleeve on my Ral Micron M21....i have tried everything i can think of...using a pen, and i havent used anything metel or hard what so ever to avoid damage to the sleeve and piston.....what else can i do? any other alternate methods?

thanks boys

i know this is a bit vague and im not pro but what about sticking that same pen into the hole where the manifold goes and trying to pry out the sleeve?..or is that what you did? any chance of heating it up?

POWLING · 02-15-2006, 10:45 PM

yeah i already tried that......no luck...i dont think heating in this case will help much.....

imported_xxfile · 02-16-2006, 07:15 AM

heating the case causes it to expand which usually does it.

turn the crank over and see if the piston pushes up the sleeve.i usually grab the sleeve with needle nose pliers wrapped in rubber.is there a lip at the top?if so grab it on the oter ridge.pull lightly,but make sure you have a firm grip.

Tie straps through the exhaust port. One to start, if it cuts the strap add one more at a time.

Heat gun to the block can help and sometime heat "cycling" can break it free. (heat block/ drop in freezer for 10 minutes and repeat with tie straps)

POWLING · 02-16-2006, 08:05 AM

hank, can you explain the method of using tie straps? i have never heard of it before.....

zoomroom · 02-16-2006, 08:24 AM

Put the tie strap (good ones, fairly thick, no dollar store junk) in the exhaust port with the piston at the bottom of its travel. then just turn the crankshaft so the strap gets caught between the piston and the sleeve, then just continue to turn, the sleeve should start to rise to the point that it can be gripped safely with soft covered pliers.

DO NOT USE THIS METHOD WITH ANYTHING OTHER THAN TIE STRAPS. Anything bigger and tougher than a tie strap or two will damage the piston.

Got this tip from an old RC Car Action in an engine rebuild article.

If you are still having trouble understanding I can post a couple pics.
