Engine Overhaul Kits

Cat engine overhaul kits offer a convenient solution for restoring a Cat diesel engine using genuine parts. Several packages are available containing all the hardware, gaskets and precious metal parts you need to complete the job properly, as well as additional remanufactured components that save your technicians hours of labor.

There’s no core charge when you buy an engine overhaul kit and the cost of a package is less than the combined total of the individual OEM items ordered separately. Rebuild kits are available for on- and off-highway, light, medium and heavy machines. Contact a Walker Machinery parts representative for assistance choosing the best solution for you.

Why Buy OEM?

Cat engines are designed to work as an integrated system. When one part wears out, it affects the overall performance of your machine. These individual parts, which include valve heads, crankshafts, piston rings and more, are designed to withstand the high temperatures and other stresses a hard-working engine produces. Choosing Cat components can provide improved performance and productivity, as well as lower overall operating costs thanks to decreased maintenance requirements and fewer breakdowns.

There are a lot of aftermarket parts and engine kits available for Cat equipment, but none offer the security and peace of mind you get from buying OEM. For a Cat machine, there’s no better choice than original Cat diesel engine parts. OEM delivers a level of performance, fit and finish that aftermarket can’t. When it comes to important engine components, even the smallest variance or inconsistency can affect fuel efficiency and cause parts to wear out faster. OEM parts may also be required to ensure your warranty stays valid
