Remanufacturing a Ford/IH 7.3L Powerstroke Diesel engine involves many steps and manipulation of certain components to complete the process. Below you'll see the components that are contained within the engine and how those components are handled by us during the remanufacturing process. Think of them as the steps towards a quality engine.
| Engine Block/Case |
|
||||||||||||||||||
|
The rebuilding process starts at the bare cylinder block/case. Every engine is stripped down to the bare block to examine it carefully to determine whether or not it will be suitable for rebuilding.
|
||||||||||||||||||
| Crankshaft |
|
||||||||||||
|
The Crankshaft of any engine is one of the primary components of the engine's internal rotating assembly.
|
||||||||||||
| Camshaft & Lifters |
|
||||||||||||
|
The Camshaft and related lifters are also serviced as part of the rebuilding process. Remanufactured lifters are used and a used but checked roller cam is used.
|
||||||||||||
| Rockers & Pushrods |
|
||||||||||||
|
Besides the Cam and Lifters, another component of the valve-train consists of the Rocker Arm Assemblies and the Pushrods.
|
||||||||||||
| Connecting Rods |
|
||||||
|
The connecting rods of the engine are extensively remanufactured, further than many machine shops do.
Later model Powerstroke engines with "powder" rods in them get new wrist pin bushings and no further machining, as these rods cannot be resized on the rod to crank bearing end. |
||||||
| Cylinder Heads |
|
||||||||||||
|
The Cylinder Heads are an important component of any engine as they are the "lungs" of the engine. Cylinder head performance is critical, maintaining that performance starts at a quality remanufactured cylinder head.

| Bolt On Items |
|
||||||
|
|
Many items are checked and re-used with a remanufactured engine, they're listed below.
|
||||||
| New Internals |
|
||||||||||||||||||||||||||||||
|
|
Below you'll see the components that simply get replaced in every remanufactured engine and what components we prefer to use to ensure you're getting a quality engine.
|
||||||||||||||||||||||||||||||
| Engine Assembly |
|
||||||
|
|
After final machining processes have been completed and components used in the engine have been inspected the engine is then assembled, and various things are checked and performed during assembly.

Upgrades & Options |
|
|
Beyond the OEM oriented rebuild offered above several upgrades and options are available. Many of the upgrades and options offered below are geared at either improving the overall durability of the engine or to improve power output, and in many cases both. |
||
| Balancing |
|
||||||||||||
|
A true balancing of the rotating assembly is a highly recommended upgrade for any engine. The Balancing is completed using a Multi-Bal 3000 balancer that uses computer software to analyze the crankshaft with calibrated bob weights. The Bob weights are used to simulate the same weight as the other components of the rotating assembly.
In Order to complete the balancing the majority of the engine's rotating assembly components must be modified.
|
||||||||||||
| Lower Compression Ratio |
|
||||||
|
|
Lowering the effective compression ratio of the 7.3L engine is a method of increasing durability of the engine while running at higher than designed power levels. There are many different ways of lowering the compression ratio of an engine. The method used here is by reducing the piston's height. Aftermarket MAHLE pistons are also available to lower the effective compression ration.
|
||||||
| ARP Head Studs |
|
||||||
|
ARP's head studs provide greater clamping force between the block and the cylinder head and are a performance oriented upgrade. The studs replace the factory Torque To Yield head bolts.
|
||||||
| Ceramic Coatings |
|
||||||||||||
|
|
High Temperature Ceramic Coatings can be applied to a number of components that are subjected to the extreme temperatures associated with engine combustion. The coating is designed to reflect heat away from the component that it is applied to, thus providing a protective layer for the component.
Most of the uses of ceramics are for the protection of the engine components to help them resist the heat that can destroy them. In some instances, ceramics can also be applied to protect external components such as exhaust manifolds and headers against rust, and insulate heat away from the engine.
|
||||||||||||
| Gapless Piston Rings |
|
||||||
|
By Using Gapless Piston Rings manufactured by Total Seal Inc., Diesel engine blow-by can be greatly reduced in the engine with a better sealing ring. This upgrade utilizes Total Seal's 2nd Ring Groove ring, and uses Mahle's top compression ring and superior 2-piece oil control ring already used in the standard rebuild package.
|
||||||
| Fluidampnr Balancer |
|
||||||
|
|
New As part of an engine package, a fluiddampr harmonic balancer can be installed..
|
||||||
| Beyond Longblock |
|
||||||
|
|
Bolt-on accessories and upgrades are available. These items can be installed before your engine is shipped to aide in the installation of the new engine into the chassis.
