Caterpillar to Perkins Engine Model Cross Reference Interchange
The AERA Technical Committee offers the following information on Caterpillar to Perkins engine model
cross reference interchange. It is important to note that these engine designations are owned in part by
the same corporation.
Use the table below to help determine the common engine model names for each company. Although
different part numbers exist for the two companies and Caterpillar engines 210hp and smaller are
Perkins engines and Perkins uses Caterpillar engines for 210hp and above.
While the above statements are accurate, it should also be assumed that not all Caterpillar engine
models will relate to all Perkins models and conversely as well. Each manufacturer may have specific
customer needs they cater too.
