Cranktrain requirements can include:

Connecting rods
Connecting-rod bearings
Main bearings
Thrust bearings
Connecting-rod bushings
Crankshaft components
Fasteners

Caterpillar C280-16 Auxiliary Sea Water Pumps

Two important documented auxiliary seawater-pump references associated with applicable C280-16 marine configurations are:

Caterpillar 473-0551 / 4730551

Description: Sea Water Auxiliary Pump

This pump is documented for applicable marine-engine configurations including:

Caterpillar 473-0553 / 4730553

Description: Auxiliary Sea Water Pump

This pump is also documented for applicable marine-engine configurations including:

Caterpillar C280-12
Caterpillar C280-16
Caterpillar 3612
Caterpillar 3616

The presence of multiple documented pump references does not mean every C280-16 uses both pumps.

It also does not mean the pumps are universally interchangeable.

Before ordering, verify:

Engine serial number
Arrangement number
Existing pump number
Cooling-system configuration
Mounting arrangement
Vessel installation

For additional information, read our Caterpillar Auxiliary Sea Water Pumps & Part Numbers guide.

Does Every Caterpillar C280-16 Use the Same Sea Water Pump?

No.

Sea water pump selection can depend on:

Engine serial number
Arrangement

Inlet and outlet configuration

The safest identification method is:

C280-16 + Engine Serial Number + Arrangement + Existing Pump NumberWhat Does the C280-16 Sea Water Pump Do?

The seawater pump circulates raw seawater through applicable external marine cooling circuits.

Depending on the vessel installation, seawater can remove heat through:

Heat exchangers
Oil coolers
Charge-air cooling equipment
Auxiliary cooling equipment
Other applicable cooling circuits

The seawater circuit should not be confused with the engine's closed freshwater or coolant circuit.

In a typical heat-exchanger installation, heat is transferred between the closed engine-coolant circuit and the raw-seawater circuit without the two fluids normally mixing.

Caterpillar C280-16 Lubrication System Parts

Lubrication-system requirements can include:

Oil pumps
Pre-lubrication pumps
Oil filters
