This liner contains a counter bore at the top in which a removable steel ring is inserted to remove the carbon from the sides of the piston preventing it from contact with the liner walls. Scraper Ring No ounter Bore Scraper Ring Liner ounter Bore

4 Power ylinder Update urrent Power ylinder components incorporate the use of a arbon Scraper Ring cylinder liner commonly known as an APR (Anti-Polishing Ring) liner and a Low Top Ring, Reduced Diameter Top Land Piston. The liner contains a counter bore at the top in which a removable steel ring is inserted. This ring scrapes the carbon from the sides of the piston and aids in reducing carbon polishing of the cylinder liner walls. The arbon Scraper Liner is designed to only be used with and Reduced Diameter Pistons. These improvements are designed to aid in decreasing oil consumption, DPF regeneration and increased oil filter flow losed Window Reduced Diameter Top Land Piston ounter Bore & arbon Scraper Ring w/integral Shim & Scraper Ring ompatibility ylinder Liner Piston onnecting Rod Open Skirt Pistons cannot be used with arbon Scraper Ring (APR) ylinder Liners. Pistons cannot be used with arbon Scraper Ring (APR) ylinder Liners. arbon Scraper Ring ylinder Liners must use a losed Window, Reduced Diameter, Pistons All six cylinder liners installed must be of the same type. Liner Shims must be replaced with new shims upon installation. Service Tool is required for Scraper Ring Liner piston installation. All one piece pistons require drilled connecting rods and drilled bearings. Machined (saw cut) connecting rods and fractured-split connecting rods require different bearings which are not interchangeable.
