When considering a remanufactured engine vs a used engine, make sure you can answer the following situations to determine the quality of the engine you are getting.

•  Is there hidden damage to the used engine, like microscopic cracks that may show up after the used engine warranty has expired?  If the used engine was in a wrecked car, this is a big possibility.  However, with our remanufactured block and new components, you can rest assured that the engine you order from us has been tested and is in great condition.
• Can you be 100% sure of the mileage on the used engine?  On a remanufactured engine from Roadmaster, you can be assured that our engines have no in-vehicle miles put on them.
• Do you know how the used engine has been treated and in what condition it is in?  With a remanufactured engine from Roadmaster, you know the utmost care has been given to build each engine to new engine specifications.  All the internal parts are new, and the remanufactured engine you buy can be trusted to last you a long time.

Roadmaster’s remanufactured engines are built using the finest new or core blocks and are built with brand new components.

Remanufacturing Transmissions

Remanufacturing a transmission involves completely restoring a transmission back to factory standards in a factory assembly line setting – making it as close to new as possible.

In some cases, the transmission is upgraded to include “bug fixes” and factory updates from the manufacturer such as modifications to the valve body as well as more durable parts (eg. higher quality friction material) to address common weak points of the transmission that typically caused the failure. This ensures that the transmission is as up-to-date as possible with the design and components used in brand new transmissions.

The process starts by disassembling a core (a broken/used transmission), then cleaning and inspecting all of the parts (crankshaft, camshaft and rods, head & block castings, etc.) and checking them against original equipment specifications.

All of the components that are identified as being out of specification (too worn out or damaged), are replaced with new parts or parts that have been requalified to meet very specific tolerances and standards.

The valve body is then tested and remanufactured back to original specification. Metal surfaces are measured and machined to the correct dimensional tolerances. All of the electronic components are tested, then new solenoids and other electrical parts are installed.

After machining and painting the case, the transmission is reassembled, quality checked, then hot/cold tested on a dynamometer or “dyno” prior machine prior to shipment. A dyno is a device that measures torque, power, RPMs and line pressure to make sure the transmission meets specifications and works properly.

Remanufacturing Engines and Testing

Remanufacturing is the process of reconditioning a “core” or worn out used engine to meet industry standard specifications.

Engines suffer from countless sources of wear and tear that can eventually destroy them. While a properly maintained engine might last hundreds of thousands of miles, a poorly maintained one can and will fail. When engine failure occurs, there are several choices, the most cost-effective solution is to choose a remanufactured long block engine.

Building a remanufactured, rebuilt replacement engine that meets original requirements is no small feat, but it’s the only way to provide the most reliable and respected remanufactured engines in the industry. Roadmaster Engine World does this by using quality parts with proven and constantly improving processes. These fully reconditioned engines are assembled with precision and impeccable quality control.

A rebuilt engine is one that has been remanufactured to prescribed standards and specifications by highly skilled machinists using state-of-the-art equipment and components. During this process many new components are installed that meet or exceed original equipment performance standards. Remanufacturing is done with precision and involves fully disassembling the entire engine, cleaning all the components and resurfacing or replacing parts that are not in good condition.

Frequently, rebuilt engines are better than the engines originally installed at the factory. They are dependable, reliable and backed by excellent warranty programs.

Engine Blocks, Rods, Crankshafts and Cams are thoroughly cleaned, tested for wear, straightness and cracks.

What is Sim Testing and How Does it Differ from Dyno Testing?

Dyno testing – is a test to an engine with it operating out of the vehicle under its own power. This means running and firing under fuel and with a load applied.

Sim tested (or simulation testing) – Is a test performed by manufacturers of rebuilt engines but is often referred to incorrectly as Dyno testing. Sim testing is the process of using a machine to spin the engine. The SimTest machine flows preheated oil through the engine while spinning the rotating assembly. This allows us to test for compression, proper oil pressure and any noises. It also allows the engine lifters to be pumped up thus aiding in eliminating any start up tapping.

The SIMTEST is a simple engine test that standardizes quality and reduces any possible comebacks. The relative success or failure of a remanufactured engine is a matter of physics, plain and simple. This machine checks it all: compression, pressure maintenance, oiling, valve adjustment, turning torques and a host of other functions.

These are checked against rigid industry standards. With the SIMTEST machine, we systematically test all mechanical functions and procedures involved in engine remanufacturing. It’s accurate and dependable and helps assure our guarantee to you for the highest quality remanufactured engine possible. So, the next time you order a remanufactured engine from us, rest assured that it is the highest quality engine

The engine is not under its own fire or running on fuel at this point. The reasons it is done in this manner, as opposed to a true Dyno test, are as follows:
