PERA’s Core Corner: No Beginning, No End To Ring References In Engines
This Core Corner is all about rings. It’s amazing how much they are a part of our lives. Of course, a symbol of commitment between married couples is probably the first that comes to mind. Type the word “ring” in the Google search engine and get beyond all the stuff that is being sold and
Crankshafts:Stock and Performance
The crankshaft is the working arm of the engine. All the force generated by combustion and the downward motion of the pistons is focused on the crank throws. The leverage effect of the force exerted on the crank journals twists the shaft and converts the up-and-down reciprocating motion of the pistons into rotational motion of
Engine Boring and Honing Equipment
Cylinder boring and honing is the heart of most engine builders’ operations. The equipment you use will have a lasting effect on the quality of the product your shop sends out the door on a day-by-day basis. While equipment varies from manufacturer to manufacturer, so too do your needs for a specific type of machine.
Secret to Success is No Secret, Says Incoming AERA Chairman
John DeBates doesn’t understand what all the fuss is about. "I’m just a guy with a machine shop," he suggests. "I’m no superhero." And yet, when John DeBates, incoming chairman of the Engine Rebuilders Association (AERA) talks, people hang on every word. Perhaps it’s because he’s just a naturally funny, engaging and friendly personality. Perhaps

Shop Line
We’ve had complaints of recurring oil leaks on some Navistar 7.3L diesel engines. Can you offer any solutions? There have been reports of engine oil leaks on 1994-2003 Navistar 7.3L diesel engines. These leaks most often occur shortly after cylinder head service has been completed. To reduce the likelihood of reccurring leaks, a new end
Engine Bearings: Stock & Performance
The importance of the engine’s bearings can’t be over-emphasized. The bearings support the crankshaft and connecting rods, and in pushrod engines also the camshaft. The bearings provide a surface for the friction-reducing oil film that allows the parts to spin without rubbing metal against metal. It’s a tough job because of the high loads created
Gessford Machine, 2004 Machine Shop of the Year
If you asked a roomful of people to make a list of the 20 most exciting cities in the world, you would probably find New York, London, Paris, Rome and Beijing on every list. While the exact order and final tally of cities might vary, it’s unlikely that Hastings, NE, would even be mentioned. But

PERA’s Core Corner: Solving The Riddle Of The V10 Chrysler Cylinder Head
In this month’s Core Corner, we ask the question: “When is something you know not what you think you know?” Sounds like a mystery, doesn’t it? For example, when is a car not a car? When it turns into a parking lot! I know, I know – don’t quit my day job. But that really
Surfacing Equipment Options
On older cast iron engines with conventional soft-faced head gaskets, as long as the surface finish on the cylinder head and block deck is roughly 60 to 100 microinches Ra (roughness average), the head gasket should cold seal and remain leak-free for the life of the engine. But on late model bimetal (aluminum head/cast iron
Coretalk: GM, DaimlerChrysler Join Forces To Produce Hybrid Automobile Engines By ’07
Although financial terms of the agreement weren’t disclosed, the collaboration is likely to involve an investment of hundreds of millions of dollars between the automakers. The first of the vehicles is to debut in 2007 – when Toyota has said it hopes its hybrid model sales will total several hundred thousand worldwide. GM, which has
Tech Notes
Engine Builders: The AERA Technical Committee offers the following information regarding engine failure on 1998-2004 Chrysler 2.7L VIN R, U & V engines. There have been reports of premature engine failure on these engines, failures that may include tensioner failures, oil consumption and engine bearing failure. It has been suggested that many of these failures
Piston Ring Technology: Stock and Performance
Piston rings have one of the toughest jobs inside an engine. They’re slammed up and down between the ring lands thousands of times a minute; they’re subjected to searing temperatures and extreme pressures; and they’re constantly scraping back and forth against the cylinder walls. In spite of all of this, the rings are expected to
Engine Kit Opportunities
In nearly all aspects of today’s competitive consumer market, the customer is king, brand means everything, and warranties on parts and services are a given, right? Great news for the value-minded shopper, but what about the supplier? In the automotive industry, of course, OEMs have been offering unprecedented warranties and financing terms for the past
Tractor Pulling: It’s Not Your Granddad’s John Deere Anymore
Tractor pulling has been with us for as long as there have been tractors. Farmers used to pull their horses, mules or oxen and, just as today, each bragged that he had the biggest and strongest. Today, at the top echelons of pulling, the technology is equal to anything else in motorsports. Although you won’t
The Angle On Valve Seats
Valve seats seem to be a fairly simple engine component but they play a critical role in sealing compression and cooling the valves. When a seat becomes worn, it may leak compression and allow the valve to run hotter than normal. The same thing can happen if the seat is out-of-round or has lost its
Ford Timing Chains and Belts
So if a customer is driving a vehicle that is more than 5 or 6 years old, he may be driving on borrowed time if the timing belt has not been replaced. The risk of belt failure goes up sharply once a belt surpasses its recommended replacement interval, which for most Ford applications (except the
Topline Automotive Buys, Reopens Hylift Facility, Engine Builder, August 2004
