Note: When you are ordering new parts, refer to the engine identification number in order to receive the correct parts. Refer to the Operation and Maintenance Manual, "Product Identification Information" for the correct numbers for your engine.

The 3044C engine is an in-line four cylinder engine. The engines are controlled by a mechanically governed fuel injection pump.

The engines have been designed for many different applications. These engines are available in two different types of aspiration:

  • Naturally aspirated

  • Turbocharged

Lifting the Engine


NOTICE

Failure to follow recommended procedures for handling or transporting engines can lead to engine damage.

To avoid possible engine damage, use the following procedure.


When you are lifting or moving the engine, use the following procedures in order to prevent engine damage.

  1. Do not tilt the engine to an extreme angle unless the lubricating oil is first drained from the oil pan.

  1. Do not turn the engine onto a side or an end surface unless the lubricating oil is first drained from the oil pan.

  1. If the oil is not drained prior to tilting the engine or turning the engine onto a side or an end surface, the lubricating oil from the oil pan can flow into the intake manifold and the cylinder bores. This situation could cause a hydraulic lock in the engine. Hydraulic lock can severely damage the engine.

  1. The engine oil should be refilled to the correct level before the engine is started.
