The verified equipment catalog identifies the engine model as C9.3.

These selected sections cover original complete/core engine arrangements, engine and CEM module installation, engine components, mounting, oil-filter routing, drains and fumes disposal. Separate original cover, cylinder-head, piston, flywheel, gasket-kit, fan-drive and oil-level-gauge versions remain separate, including sections without supplied drawings. Fuel-tank and refrigeration/compressor references remain in their original engine-installation and machine context; they do not establish standalone engine fitment. This is not the entire machine parts book. Retain every arrangement, serial/date applicability and original note; this is not the entire machine parts book. Check machine and engine nameplates, arrangement numbers, serial ranges and original notes before ordering. This section does not establish interchangeability with other configurations.
