Here at Industrial Engines, we are passionate about providing you with the right engine for your machine. In order to do that, we ask for the serial number of your engine.

Oftentimes, people struggle to find their serial number, which can often be tucked away in some awkward corner on an engine. We’ve put together some pointers on where to find your serial number on each of our core brands: Perkins, Deutz, Kubota, Cat and Lister Petter.

PerkinsOn a Perkins engine, there is a plate under the injection equipment, which has the serial number stamped into it. For each model of Perkins engine, there is a build list that starts with 2 letters, followed by 5 numbers. The serial no. comes directly after this, starting with another letter and 6 more numbers. Often, there is another letter on the end, which relates to the year of manufacture (Example: HP50995U980055N)

DeutzOn the Deutz 1012/1013 and 2012/2013 engines, the serial number (often called Motor No.) is normally on a plate on the rocker cover, or stamped into the block, as shown on the image below. Deutz 912/913/914 ranges have a plate at the bottom of the engine block with the serial number stamped into it. If the plate is missing, the serial number can be located next to the injection pump, stamped into the block, see image 2. A Deutz serial number is generally made up of 6-8 numbers.




KubotaOn a Kubota engine, the serial number is found on a sticker on the rocker cover, or stamped into the block under the injection equipment. A Kubota serial number is usually 6-7 digits, sometimes made up of only numbers, other times including a couple of letters.

Lister PetterThe serial numbers on lister petter engines are found on a plate near/on the rocker cover. The serial number consists of around 8 numbers, followed by a few letters (showing the model) and then more numbers (example: 10005635LPW2A02)

CatCat serial numbers are stamped into a plate, which is generally on/under the rocker cover. Other times, the plate can be found just above the sump. A Cat serial number tends to be 8 numbers and/or letters. Mostly, they are 3 letters followed by 5 numbers, however, this does vary.


Often the plates on engines get covered in all kinds of grime, so we would suggest rubbing some emery paper over the plate, in order to be able to see the serial number better.

There are a few instances where this varies, so if you still can’t locate your serial number, feel free to send some pictures of your engine to and we’ll try and identify it for you!
