A Quick Guide to Diesel Engine Rebuild Kits

Diesel engines, such as on long haul trucks, get put through their paces. If your engine isn’t running properly, it might be time to look into getting a rebuild kit instead of completely replacing the engine. The two most common types of rebuild kits, in-frame and out-of-frame, help you replace sets of parts, rather than having to replace a single part at a time, helping with wear. Here are the differences and how you can determine which you might need.

 Determine the Engine and the Damage

Before deciding which rebuild kit you need, your first task is to determine what engine you have and what the damage is. Determining the engine make and model should be fairly easy but is essential when it comes to getting the right kit. Next, determine the damage, even if it is just general wear and tear. How are the pistons? The piston rings? The oil pan gasket? The cylinder heads and seals? The level of damage determines which kit you will need. You might need other parts, as well, such as replacing a Cummins ISX injector, so it’s vital you note every part that needs to be replaced.

Inframe Rebuild Kit

The most common type of rebuild kit, the inframe kit is what you want when there is obvious damage to pistons or they are no longer working well. They usually come with the pistons, cylinder heads, a re-ring kit, liners, and more. They often also include an upper engine gasket kit, and might have piston skirts or crowns, depending on the engine. For example, a Caterpillar C15 ACERT Inframe Kit comes with six pistons, a piston ring set, six wrist pins and locks, cylinder liners and seals, a connecting rod bearing set, a main bearing set, thrust washer plates, an upper head gasket set, and an oil pan gasket. The inframe kit is named for being able to replace and rebuild the engine without needing to leave the frame of the truck, helping you save money on labor.

Out-of-Frame Rebuild Kit

The out-of-frame kit, also referred to as an overhaul kit, is for when your engine has suffered a catastrophic failure or is encountering more leaks than an inframe kit can seal. If you have to pull the engine out to fix the problem, such as needing to take out the crankshaft, this is what you will need. It can replace most parts as well as reseal every seal on the engine. Out-of-frame kits include everything found in the inframe kits, as well. As the name suggests, these rebuild kits require the engine block to be removed from the truck frame. However, it’s an overhaul of the engine, and it will make your engine like new.
