You know you have to have them machined to fit pistons anyways. Better off letting a shop do it.
And no you can't just use a shop press. You have to heat the aluminum evenly so it expands enough to get the sleeve in an out plus you have to line up all the ports.
The manual doesn't say specifically. All the ones I have seen done you heat the cylinder to remove and install the sleeve so the cylinder expands freeing the sleeve.
all this sounds very easy lol ,Heat is the preferred method. 400 degrees for half an hour, and they typically slide right out.
when you place the new sleeve in, the heated cylinder allows you a minute or so to get the ports in perfect alignment, nearly impossible to do with a shop press.
im using same sleeves and original pistons from same running motor ( i need to change rotted aluminum cylinder part) do i still need any machining besides top decking ?? running motor had 150 psi and pistons look great no scoring,, these are stock standard bore, ill get new rings .You know you have to have them machined to fit pistons anyways.

If you knew how to properly hone and size a cylinder to a piston, you wouldn't ask this question. Final honing a cylinder is a whole lot more than putting some hatch marks in an X pattern with your 3 jaw stone harbor freight honing tool for 19.99what makes this engine so critical that i have to send them to a machine shop if using same sleeves and pistons ? what has to be machined besides a top decking ? i can handle a hone job .
I prefer a ball hone then I can't mess anything up and break those stupid little stones, LOL.If you knew how to properly hone and size a cylinder to a piston, you wouldn't ask this question.

Piston to cyl clearance is .005"=ish. roughly 8 times thinner than the average human hair. But go ahead, stick the cylinder in your kitchen oven and have a go.
lol ,asking why .and what needed to be done besides decking, and honing , checking for straightness was the missing info i needed , but isnt specific to seadoo only(basically what i was asking). i do know about that and understand why after heating up the parts ,even getting a new cylinder..etc etc i wont take a chance on ruining a bunch of parts etc. . i dont have a machine shop. so no need to hear or record all 1000's or 1,000,000 i dont have.... i will try the sleeve swap i have six cylinders and will try on two im not going to use first, and i can hone the cylinders that is a piece a cake.. i was always told dont be just a parts changer. this is why i ask .sorry, plus i need to know what to tell the machine shop i choose what i want done. didnt know if seadoo needed a special procedure but i do now . thanks much .

I bore and hone blocks in my shop.
On GM and other applications we use a sleeve puller and and press, so I was curious why people were using ovens.
I know some shops use "rod heaters" to remove wrist pins from press fit rods because they don't have the appropriate fixture to do it with a press, so I was wondering if it's that type of scenario.
Does the brp service manual really say to do it that way?
