Used cat 3306 engine

Types of CAT 3306 engines

The CAT 3306 motor was manufactured by the Caterpillar company. This motor exists in two versions: the used CAT 3306 diesel engine and the used CAT 3306B IL (Indirect Injection Long Block). The adoption of the indirect long block version boosted the engine's performance and made it more fuel-efficient.

• Used CAT 3306 diesel engine:

• Diesel engines operate by injecting fuel into highly compressed and hot air, which results in a combustion process. These types of engines are generally found in vehicles that need added power and torque, like trucks and heavy machinery.

• Used CAT 3306B IL engine:

• IL stands for Indirect Long Block. The 3307B model introduced a new improved feature to the Caterpillar 3306 engine by employing an indirect injection system. Substantial improvements were made to indirect injection engines, such as making them more fuel-efficient and smoother to run. The improved 3306 motor also had remarkable power output, notable longevity, and easier maintenance.

How to Choose Used CAT 3306 Engines

When choosing the proper used CAT engine, there are many factors to consider to match the specific equipment and needs.

• Understanding the Requirement

  The first step is to define the application clearly. It includes identifying the equipment where the engine will be used, such as a forklift, excavator, generator set, etc. Then, figure out the required power output and horsepower range. Analyze the working environment, whether it needs to perform well in high-altitude areas or face humidity and marine corrosion. Consider the operational workload, frequency, and engine's duty cycle, too.

• Matching the Specs

  Used CAT 3306 engine buyers need to make sure the following crucial specifications are compatible. The following details must coincide with the ones existing in the equipment: the physical dimensions, the mountings, electrical connections, and the transmission link-up.

• Checking the Health

  It is essential to check a few parts like turbo, injectors, water pump, oil pump, fuel pump, starter motor, alternator, and the belts and hoses. Also, the used engine's overall body must be devoid of any cracks or damage.

• Reviewing the History

  Before making the purchase, it is wise to know the complete service history of the engine. Ask the supplier if the engine was overhauled previously and if vital parts like the turbo or fuel pump were replaced. Also, the buyer must know the working hours and any past incidents that might have affected the engine's health.
