Before you buy

These engines go into trucks, buses, motorhomes, construction and farm machinery and generators, so confirm the exact model on the dataplate first. Fuel, lubrication, cooling, air, exhaust and electrical groups are in Volume 2, sold separately.

Your engine's dataplate shows the engine model, the engine serial number (ESN) and the CPL number. Compare those with the models above. If you're not sure, email us the dataplate details and we'll check for you.
