353-5617: Cylinder Bore Liner Seal Insert

Description: Seat inserts are important components of cylinder liners, which are fitted into engine blocks and prevent pistons from wearing through cylinder bores Attributes: Inside surfaces feature a uniform cross hatch pattern for faster ring seating, proper ring seal, uniform oil distribution, and long life. Flanges are roll burnished in the radius for increased strength and resistance to cracking. Heat-treated high-grade gray iron construction provides exceptional strength and long life. Controlled flange head thickness guarantees a precise match with the block and head. Precise manufacturing tolerances ensure perfectly round bores for efficient oil control and proper fit in Cat engine blocks.
