Description
CAT 157-7130 is identified in the supplied CAT stock list as VALVE-EXHAUST. Exhaust valves open during the exhaust stroke to release combustion gases and close during compression and combustion to maintain cylinder sealing. Valve stem diameter, head diameter, seat angle, overall length and material depend on the original CAT cylinder-head arrangement. Correct valve-to-seat contact supports heat transfer and durability. Verify valve guide, seat insert, cylinder-head group, engine serial number and CAT SIS before installation.
