Removing sleeves from cylinder block

[chuck hahn]

Never tried to remove one intentionally. But today as I was baking the jugs to hard cure the engine paint, the sleeves simply slide out effortlessly.

So, Heres an easy way to remove the sleeves. Simply put the jugs in an oven at 300 for about an hr or something simular ( as long as it doesnt get too hot..like 500 or something). As the aluminum expands, the sleeves loosen up and will slide right out.

I called the Bike Whisperer ( Randy ) and he told me the process for inserting new sleeves is this..Heat the jugs as in the above situation and throw the new sleeves in the freezer. Heat expands the jugs and the cold contracts the sleeves. Now marry the two up and lay it on a flat surface to hold the sleeves flush with the cylinder surface and just let it all cool down..Done.

Nessism found that one out one time while he was baking the cylinders from one of his bikes.

So, next time you want to bake the paint on your cylinders, just turn them upside down.

Wont matter Steve...they will still fall out as you lift the cylinders. maybe if you slid them off on a smooth flat board or something, but to lift them wont be of any use. Its a pretty good trick though!!

Umm you'll still have a problem. They do rise up a bit no matter how you support them.



So when your done baking give them a tap with a rubber mallet and set them back in place while its hot..
