Exchange engines are remanufactured from all brand new ISO 9001 new parts from an engine core. All parts are machined to exact OEM tolerances and in essence the engine is returned to its original quality unnoticeable from the day it left the factory. Many times older engines are made better than new through remanufacturing as the market has made improvements in parts and technology.
Upon completion of the new remanufactured engine you simply send us back your old core so we can keep an active inventory of cores for our next customer. Our core policy is very liberal; if the hard internal parts of the engine are salvageable (cylinder head, crankshaft, camshafts and lifters, rocker assemblies and block) then we will return your core deposit in full. If some components are beyond repair we will offer partial credit based upon the value of your core. Engines can also be purchased on an outright basis where the core charge is included into the sale.
Our 18 machinists and master engine builders have the ability to remanufacture the Cummins 4BT, Cummins 6BT and Caterpillar 3306 back to longblock status. Our longblocks come with complete cylinder head, camshaft and lifters, connecting rods, crankshaft, pistons, rings, liners, gaskets, front and intermediate covers. The engine also comes timed and ready to go. The fuel system (injectors, and fuel pumps), water and oil pumps as well as turbochargers can be ordered with the engine but will not be installed on the longblock. If you are looking for a drop in crate engine we also have a great article which tells you how to research a crate engine as well as how to properly swap a crate engine into any vehicle or industrial application.
Repair and Return:
Many customers don’t need a fully remanufactured engine but rather have a component or two that need repairing. We have the ability to fully remanufacture individual components back to OEM specifications and return them back to you. We can either do a complete repair and return on your engine, remanufacturer specific components such as the crankshaft or cylinder head or ship you the parts you need to repair non-critical components yourself.
In some instances when components cannot be remanufactured it will become the responsibility of the customer to replace them if they elect to do so. There is no core charge associated with Repair & Return engines and are purchased outright.
