Technical notes

468-8824 is the intake (inlet) valve fitted in the cylinder head of Caterpillar 3500-series diesel engines, including the 3512B marine generator/propulsion platform that shares head and valve-train architecture with the 3508, 3512, 3516 and 3516B. Distributor listings consistently pair it with exhaust valve 468-8825 (alongside related valves such as 210-2542 and 500-8527), reflecting the head's separate intake/exhaust valve part numbers. It is a wear/overhaul item replaced during top-end or cylinder-head rebuilds, where intake and exhaust valves, guides and seats are serviced as a set. Buyers must distinguish the diesel 3500 valve from spark-ignited G3500 gas-engine valves, which carry different fitment despite a similar number family.

Compliance

Frequently asked questions

Does Caterpillar 468-8824 fit the 3512B marine engine?
Yes. 468-8824 is the intake valve used across the Caterpillar 3500-series diesel family (3508/3512/3516 and the B variants), which share the cylinder-head and valve-train design used on the 3512B.
What is the matching exhaust valve for 468-8824?
Distributor listings pair intake valve 468-8824 with exhaust valve 468-8825 in the same head.
Will this valve fit a G3508/G3512/G3516 gas engine?
No. 468-8824 is corroborated for the diesel 3500-series. The spark-ignited G3500 gas engines use different valve fitment, so confirm the engine is diesel before ordering.
