FAQ
What is a cylinder sleeve used for?
A cylinder sleeve, or liner, is pressed into the engine block to restore a worn or damaged cylinder and give the piston and rings a fresh bore surface. It is a common repair during a rebuild or when a cylinder is beyond standard overbore limits.
What are the dimensions of the CSL268 sleeve?
Melling lists this sleeve with a 4.5625" bore diameter. Confirm these against your block and pistons before ordering.
Does this sleeve require machining to install?
Yes. Cylinder sleeves are installed by a machine shop, which bores the block to accept the liner and then press-fits and finish-hones it to the correct bore. This is not a bolt-in part.
Is this sleeve sold individually?
This listing is for the Melling CSL268 cylinder sleeve. Order one per cylinder being repaired.
