Align Yourself
The crankshaft main bores are the foundation of every engine block. The alignment of the main bores is important because their position establishes the centerline of the crankshaft and how the crank aligns with the cylinders, deck surfaces and camshaft. Misalignment in the main bores can cause binding and premature main bearing wear. Misalignment occurs
Rebuilding The Ford 2.0L
The old 1.9L was modified and upgraded in the process of making it into the 2.0L. The new engine was bored and stroked, it had siamesed cylinders that made the block stronger and quieter, the crank had four more counterweights that made it run smoother, and it had domed pistons for more compression. The
Coolant contamination of engine oil for 1996-2003 GM 3.1L or 3.4L VIN J & E engines
Engine Builders: The AERA Technical Committee offers the following information regarding coolant contamination of engine oil for 1996-2003 GM 3.1L or 3.4L VIN J & E engines due to failure of the intake manifold gasket. GM has redesigned a new intake manifold gasket (p/n 89017279) to reduce the chance of failure. The material used in
How can the distributor cause damage to a freshly rebuilt engine?
How can the distributor cause damage to a freshly rebuilt engine? According to the AERA technical committee, cracked magnets in distributors on some 1987-2002 GM engines can indeed be a problem. In some instances faulty distributors have been reinstalled after an engine rebuild and caused premature engine failure. Distributors with cracks in this area (see
Valve lifter failure is experienced on Mack MIDR 06.02.12 or MIDR 06.02.26 diesel engines valve lifter failure is experienced on Mack MIDR 06.02.12 or MIDR 06.02.26 diesel engine valve lifter failure is experienced on Mack MIDR 06.02.12 or MIDR 06.02.26 d
If a lifter failed in a 2001 Mack truck, how concerned should I be about the rest of the components? If valve lifter failure is experienced on Mack MIDR 06.02.12 or MIDR 06.02.26 diesel engines with original style lifters, the AERA Technical Committee recommends that all 12 lifters and pushrods be replaced with improved components.
Welding: Why weld aluminum?
As we are all aware, many of the components of the engines our industry remanufactures utilize this "mystery" metal. It first started with manifolds, then cylinder heads, timing covers, oil pans, lower main bearing girdles and finally blocks and all accessory mounting brackets. Don
The lower intake manifolds on some Ford vehicle models are not fitting correctly after machining
Engine Builders: Some AERA members have reported that the lower intake manifolds on some Ford vehicle models are not fitting correctly after machining. To reduce the likelihood of coolant contamination of engine oil, a revised, thicker intake gasket is now available for the 3.8L and 4.2L Ford car and truck engines. These models have VIN
Ohc Journal Repairs
One of the advantages of an overhead cam cylinder head is that it eliminates the need for certain valvetrain components. Mounting the camshaft in the cylinder head rather than the engine block eliminates the need for lifters and pushrods. On some OHC engines, the cam lobes run directly atop the valve stems. On others, cam
Special procedures to follow when working with Ford BSD engines
Q: Are there any special procedures to follow when working with Ford BSD engines? A: The AERA Technical Committee offers the following information regarding the crankshaft dynamic balancer on Ford BSD four cylinder diesel engines. The engines that are affected are the BSD 442, 442T, 444 and 444T. The 442 series engines are 256 cubic
Rebuilding the Ford 4.6L SOHC Engine
The 4.6L was lower, shorter and lighter than the 302, but the base engine made more power than the 302, got better fuel economy and passed all the emission tests without a thermactor pump. Ford called it its “modular” engine because it was part of a whole new family of engines that were intended to
Heavy Duty Technology: Piston Failure Analysis
The air/fuel, coolant and oil systems and relationships between various engine operations and the cylinder liner temperatures are critical to maintaining proper operation of all cylinder components. A variety of conditions can cause excessive piston growth or melting, and each will cause varying results – including catastrophic engine failure. The correct air/fuel ratio balance of
Dirt Track Dollars In the Shop and On the Track With Malcuit Racing Engines
It’s sometimes said that racers have motor oil or high octane racing fuel in their blood. Fearless drivers are accused of having ice-water running through their veins. For Strasburg, OH’s Brad Malcuit, the most likely ingredient pumping through his bloodstream is dirt, a fact he’ll happily attribute to family heritage. Malcuit is owner of Malcuit’s
Engine Crack Detection Technology
It doesn’t matter if you’re rebuilding a high mileage engine and reusing salvaged components or using brand new parts right out of the box – any highly stressed component or casting that has to withstand high loads, temperatures and/or pressures should always be inspected to make sure it is free from cracks or other defects
Rebuilding The Ford 3.8L Engine
They needed an economy engine that would fit in their new cars, and they needed it fast. They had a couple of old inline sixes and a small German V6, but none of them were designed for fuel economy or the coming emissions standards, and the 250 cid engine was so tall that it wouldn’t
Coretalk: September 2001
Ford Plans to Revamp Parts Distribution Network Ford Motor Co. is working to restructure and expand its United States parts distribution network to deliver service and repair parts to its dealers faster and more efficiently. Over the next three years, Ford plans to increase the number of parts distribution centers from 10 to 21, creating
Back to Basics: Preventing Piston Problems
Burned pistons. Scuffed pistons. Cracked pistons. These are problems no customer wants to experience in an engine you’ve built. Warranty claims can kill your business, so here are some tips on how to prevent these and other common piston problems. First and foremost, if you’re custom building an engine that has already suffered some kind
Ford 4.0L V6 Engine
The original 2.6L engine was replaced by the 2.8L, which was upgraded to the 2.9L and then finally bored and stroked to make it into the 4.0L that was used in the Rangers, Aerostars and Explorers starting in 1990. It was replaced by a SOHC engine from this same family at the end of model
Predicting the Future of E-commerce in the Aftermarket
Trying to predict the future of business is sometimes about as accurate as looking into a crystal ball. A reflection of the truth may be there, but the image can be easily distorted by timing, funding and unpredictable customer whim. Despite the uncertainty of these predictions, there are those who make it their business to
Torque-to-Angle/Yield Threaded Fasteners
All the original equipment manufacturers (OEMs) have fastener labs with lots of sophisticated equipment and well-educated people working on fastening issues. They even have their own professional association – The Bolting Technology Council – which holds meetings and seminars about fasteners. I’m not a fastener engineer, and I’m not going to make you into one.
