Request an engine or partFinding the right Caterpillar (CAT) C6.6 engine
Browse the listed Caterpillar (CAT) C6.6 engines above and compare each item's recorded condition, configuration and location. A shared model name does not establish that two engines are interchangeable.
Identification to compare
Use the engine tag and serial number first. Compare the arrangement or CPL when recorded, horsepower, application and the components included in the listing. Send tag photographs if you need help identifying an option.
Compare the actual item
A complete engine, a core and an individual component are different purchases. Read the listing description and confirm any accessories you need, such as the ECM, wiring, manifolds or flywheel housing. Blank specifications mean the information has not been supplied.
Freight and pickup
Check the item's location and provide your delivery ZIP code and unloading arrangements. Freight, pickup, core deposits and any warranty terms are confirmed for the particular sale.
