State-of-the-Art Manufacturing Facilities

We provide some of the most advanced rebuilt engines available. Our facilities located around the country operate with a combined total of nearly one million square feet. These facilities house state-of-the-art equipment that allows us to remanufacture, rebuild, and re-engineer a variety of engines, as well as store and distribute them around the country.

Powertrain Products keeps all of our equipment and manufacturing processes up-to-date. By implementing modern solutions, our facilities are among the world’s best for engine rebuilding and remanufacturing. We hold industry-recognized certifications such as ISO14001, ISO9002, and QS-9000. As a result, our manufacturing standards are comparable to those in top OEM facilities.


Remanufacturing Process

The remanufacturing process begins when we receive a core engine. The Powertrain Products team disassembles the engine and then hot tanks it. This removes all the deposits and rust from the cores. Next, we go over each component and fix or replace anything weak or broken. To thoroughly track the rebuild process from day one, we record all the serial numbers within the engine. Because we keep the entire engine remanufacturing process as thorough and detailed as possible, our rebuilds always come out better and more durable than their OEM counterparts.

Block Boring

Powertrain Products bores blocks using state-of-the-art CNC equipment to produce finishes only seen at the OEM level. We invest in the right equipment to meet today’s demands for increased compression and tight piston ring clearances. Older machining equipment will work for the short term but is unable to keep the strict tolerances needed to produce an engine that can last 400,000 miles. Because we have the right CNC equipment for precise block boring, you’ll have a longer lasting engine.


Crank Grinding

Powertrain Products is one of the few engine rebuilding facilities to use CNC crank grinding machines and Adcole crank gauges. With these machines, we can accurately check for proper balance, straightness, and concentricity. This allows us to refinish crankshafts to specs that exceed OEM tolerances in most cases. This will ensure not only proper oil pressure and volume upon assembly but also longevity in the bearing surfaces for years to come.

Cylinder Head Machining

We use a variety of state-of-the-art cylinder head machines, including Serdi & Rottler machines and our own CNC surface cutters. In modern engines, the engine’s head bears most of the workload. For example, you’ll find single and dual overhead cams in all engines. This, coupled with the vast use of variable timing in most engines, accomplishes better fuel economy and proper seat alignment. That’s why proper head machining is imperative. At Powertrain Products, we take great care to perfect the cylinder head machining process. We pride ourselves in creating precise and well-engineered cylinder heads that are the best on the market.



After we build new parts and improve on OEM components, we start reassembling the engine. During this process, we fit the blocks with new pistons, rings, and bearings. We also fit the valve train and camshafts if needed. If there’s a timing chain in an engine, we install a new timing chain and tensioner. Any engines with timing belts get a new belt and tensioner, as well as a water pump and oil pump if the belt drives these parts.


After the final assembly, we move the engines onto our sim test cell. This is a simulation test to measure the engine for proper operability. We use a top-of-the-line RSC sim tester. This is a vast improvement over the testing equipment still in use at most facilities today.

The RSC sim tester measures the compression in each cylinder, as well as the oil pressure and volume. It also actuates and tests the camshaft phasers, if applicable. The proper testing of camshaft phasers is necessary. It’s not only to confirm that the camshaft phasers are working upon completion, but it’s also to monitor the engine’s oil volume and pressure during activation. This ensures that the common ticking noises many of these engines are plagued with never occur in our remanufactured engines.
