Choosing the correct reference

Read the full engine designation from the identification plate before choosing a procedure. The family name alone does not establish compatibility with every TN engine, and the E and TE suffixes must be respected. This reference concerns the engine; the host machine's service manual remains the appropriate source for hydraulic, chassis and machine-control work.
