Sleeve press near reading

(1/3) > >>

Topcat:
Hey Guys,

Been trying to search for a decent engineering / machine shop near reading that would be able to press out a damaged sleeve and fit a new sleeve from another cylinder but can't seem to find anywhere, been phoning round and either they don't want to know or they've stopped offering this service.

Any recommendations?

Cheers

What bike? Trouble is you cant guarantee proper alignment and seating with a used sleeve.

Trigger:
Any company that says there can do this can not be trusted. As Bryan has said, it is a alignment problem. A piston is not round, more of a oval so, the piston will ware the sleeve to that shape. If you put another sleeve in and it is not spot on it will twist the rod as it is trying to find its shape.

You can move sleeves from one set of barrels to another as long as you re bore to a oversize  ;)

It's a cb550f2 Basically a previous owner seems to have made a mess of the cylinder and head. So managed to source a new head and used cylinder, cylinder looks to be in pretty good condition the bottom of one sleeve which appears to be dented had I noticed this earlier I could have probably returned to seller but new baby and lots of stuff in boxes still I didn't manage to open it. The old cylinder sleeves seem to be in ok condition. I need to get a picture uploaded as it's right at the bottom so not entirely sure if its going to cause a problem. Will pop out later when I get a second.

I havnt got any blocks to hand but from memory the top flange has a "flat" where the 2 liners adjoin.
Now if you find an over that you can use, NOT THE KITCHEN ONE, put the block in the oven  till hot and if you turn it upside down and tap on appropriate blocks the liners will come out.
On the good liners you need to find a way of marking them so they can be re fitted in the correct "hole" and in the correct orientation, this can not, obviously, be anything that deeply marks the gasket surface.
You SHOULD then have the block "decked" and rebored to suit oversize pistons and ensure the gasket surface is flat. You could, of course, do without those operations but that is not good engineering practice and a risk.
