Before you buy

This is the in-chassis repair manual a truck shop uses day to day. For rebuilding components on the bench, the M11 shop manual goes into more depth. Note that 1996 is the date the manual was printed, not an engine model year.

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.
