Sleeving and honing of a Subaru block at PRO STOCK (Almaty). Blocks with damaged or worn cylinders are restored by installing dry sleeves: press-fitting, final boring to the working piston size and plateau honing for a correct oil film.
What we do
- block inspection, cylinder measurement in four planes;
- sleeve installation with hundredths-of-a-millimeter tolerance;
- boring to the working size of the piston set;
- plateau honing with a factory-spec crosshatch;
- final measurement of every cylinder, piston-to-cylinder matching.
