Description
CAT 394-4400 is identified in the supplied CAT stock list as VALVE-EXHAUST. Exhaust valves open during the exhaust stroke to release combustion gases and close tightly during compression and combustion. Valve stem dimensions, head diameter, seat angle, material and temperature capability are matched to the original CAT cylinder-head arrangement. Correct valve-to-seat contact is essential for heat transfer and engine durability. Verify cylinder-head group, valve guide, seat insert, engine serial number and CAT SIS before installation.
