An engine overhaul kit is a set of replacement parts that are used to restore an engine to its original specifications. These kits typically contain parts such as pistons, rings, bearings, gaskets, and seals. Using an engine overhaul kit is that it ensures that all components are designed to work together. This can help to prevent compatibility issues that can arise when replacing individual parts.

Advantages of Overhaul Kit
Long-Lasting Parts
The first pro of overhaul kits is that they come with durable, long-lasting parts. These parts are brand-new, so you can count on them to last for 1,000,000 miles with regular maintenance. A couple of parts that you’ll find in an in-frame overhaul kit are rod bearings, gasket sets, pistons, and thrust washer sets.
01
Saves Money
Another pro of overhaul kits is that they help your business save money. Brand-new diesel engines are expensive, and your truck might not need a new engine to run smoothly and efficiently. Instead, you can replace some of the main parts of your engine with an in-frame overhaul kit for a significantly lower price.
02
All Components Work Together
It ensures that all components are designed to work together. This can help to prevent compatibility issues that can arise when replacing individual parts. Engine overhaul kits also typically contain high-quality replacement parts that are manufactured to meet high standards, ensuring reliable and long-lasting performance.
03
More Cost-Effective Than a New Engine
One of the main reasons to perform an engine overhaul is you can ensure that everything is in working order without having to buy a new engine. More often than not, overhaul kits are a smarter investment and offer an opportunity to extend the life of your current machine.
04
Extended Service Life
Overhaul kits are more than just convenient. They extend the life of aging equipment and reduce the risk of major repairs that can lead to downtime. As your equipment gets older, engine overhauls become increasingly strategic investments that can boost your productivity and benefit your bottom line.
05
Building on what you’ll find in an in-frame kit, a complete overhaul system will add a lower gasket set, and every other gasket, seal, or O-ring the engine will need. But before that, a full teardown of the engine and deep-clean of all of its salvageable pieces has to be performed. With those steps completed, individual components can be tested and inspected, followed by a combination of reconditioned and brand-new parts being used to put the engine back together.

Types of Overhaul Kit

In-frame Engine Overhaul kits
In-frame kits are used for minor engine repairs and typically include only the parts necessary for repairing the engine without removing it from the machine. Our kits typically include gaskets, seals, bearings, and other internal engine components that need to be replaced.
Out-of-frame Engine Overhaul kits
Out-of-frame kits are used for major engine repairs and involve removing the engine from the machine, requiring a complete overhaul. These kits typically include all the components from the in-frame kit, plus additional parts such as pistons, liners, and connecting rods.

Engine Rebuild Options
BRONZE Overhaul Kit
The BRONZE overhaul kit is your low-cost repair option and includes value-added components like Cat oil filters and fuel filters and components you might not think of replacing, such as exhaust sleeves and exhaust manifold studs.
SILVER Overhaul Kit
The SILVER overhaul kit is suitable for a basic in-frame overhaul and is similar to competitive in-frame overhaul kits. It builds on the Bronze overhaul kit and has no core charge.
GOLD Overhaul Kit
The GOLD overhaul kit is suitable for a basic in-frame overhaul and includes the core parts from the Bronze kit and the added bonus cylinder pack assemblies. Reman cylinder packs are beneficial because the rods, pistons, rings, and liners come preassembled, saving four to six hours of labor when compared to the Silver overhaul kit.
PLATINUM Overhaul Kit
The PLATINUM overhaul kit includes all the components from the Gold kit plus a cylinder head assembly, Fuel injectors, a water pump, and a oil pump. The Platinum overhaul kit optimizes engine performance and fuel economy and maximizes the built-in second or third life of your engine.
Component of Overhaul Kit
An overhaul kit typically includes several components that are used to restore or rebuild a machine or system.
Gaskets
These are used to create a seal between two surfaces and prevent leakage of fluids or gases. They are commonly used in engines, pumps, and other mechanical systems.
Seals
Seals are used to prevent leakage or contamination of fluids or gases. They are often used in hydraulic systems, transmissions, and bearings.
Bearings
Bearings are used to reduce friction and support rotating or moving parts. They are commonly found in engines, pumps, and gearboxes.
O-Rings
O-rings are a type of seal that is shaped like a ring. They are used to create a seal between two parts and prevent leakage. O-rings are commonly used in hydraulic systems, plumbing, and automotive applications.
Pistons
Pistons are cylindrical components that move back and forth within a cylinder. They are commonly found in engines and hydraulic systems.
Valves
Valves are used to control the flow of fluids or gases within a system. They can be found in engines, pumps, and plumbing systems.
Filters
Filters are used to remove contaminants from fluids or gases. They are commonly found in engines, HVAC systems, and hydraulic systems.
Belts
Belts are used to transmit power between two rotating shafts. They are commonly found in engines, compressors, and conveyor systems.
Oils and Lubricants
Overhaul kits may also include oils and lubricants that are specifically formulated for the machine or system being overhauled. These are used to reduce friction and ensure smooth operation.
