ENGINE SERIAL NUMBERS AND WHY THEY ARE IMPORTANT

Why we need your engine serial number.

Think of it as the DNA of your engine

The engine serial number (ESN) on your diesel engine tells us how your engine is configured for your unique piece of equipment or truck. Some manufacturers refer to the ESN as a Motor no. or Unit No. The engine serial number gives us the following information so we can quote an exact drop in:

Your serial number gives us your “build list” which tells us exactly how your engine is configured. We need all of this information to make sure we are shipping the correct engine for your exact application, piece of equipment, or truck.

HOW TO LOCATE YOUR ENGINE SERIAL NUMBER

This can be tricky depending on the make/manufacture of the engine. Usually there is a tag on the valve cover that will give you your engine serial number. Sometimes that tag is missing and you will have to locate the serial number engraved or stamped into the block. 

We are always available to help you and we have a series of videos that can help you find where your serial number is stamped on the block.

THIS TAG does not have your engine serial number on it

Many people confuse the Emission Control Tag with the engine ID tag. 

The only time this tag is helpful is when you have a special Perkins, CAT etc. engine and we need the Family number to quote. We will let you know if we need this number.
