Performance Small Block: Chevy Engines
Small block Chevy engines long ago became mainstays in both thetraditional and high performance marketplace. So many of themhave been rebuilt over the years, and so much has been writtenabout the rebuilding process, it would appear that nothing moreneed be said. But the small block engine has changed over the years and so haveconsumer preferences
Shot Blasting Equipment Maintenance: Simple Does Not Mean Maintenance-Free
The technology of hurling steel or glass shot at more than 100 mph is pretty simple. But in the world of shot blasting machines, simple does not mean maintenance-free. The essence of these machines, no matter what their design, is that clean core parts come at the price of dramatic wear-down of media, as well
Rebuilt Market Reviews – Engines Market
Total engines remanufactured by all production engine remanufacturers (PERs) in 1995 increased a modest 3.5%, growing to 1.318 million units last year compared to 1.273 million units produced in 1994. Production totals are based on a U.S. and Canadian universe of 120 PERs that produced an average of 10,609 remanufactured engines annually in 1995. Survey
Rebuilt Market Reviews – Cores Market: The Perfect Example Of Supply And Demand
In some businesses, the classic law of supply and demand is hard to identify. But that’s not the case in the core business. “The core market is the perfect example of supply and demand,” comments John Lathan, plant engineer at The Hastings Co., a rebuilder in King, NC. “When one company is looking for a
Perspective On Using CBN Versus Polycrystalline Diamond (PCD) Cutters
In your June Shop Line you offered Jerry Lawson’s of DCM Tech, Inc., perspective on using CBN versus poly crystalline diamond (PCD) cutters. Have any other manufacturers voiced their opinions? In PERA’s May 1996 Current Concerns publication, Andy Rottler of Rottler Manufacturing made the following observations on CBN versus PCD cutters:Rottler says that due to
Letters: Test Data For Failing Rectifiers Requested
The article by Donald Yuhas, “Dissecting CS-130 Diode Failure,” in the May, 1996 issue of Automotive Rebuilder gave electrical rebuilders insights into the ways that diodes can fail. The author concluded that high “current pulse” technology is needed for successful screening-out of diodes that will likely fail in the vehicle.While I share that conclusion, the
Caliper Clinic: Rebuilders Not Only Can Improve An OE Design, But They Can Also Improve The Consumers’ Opinion
Rebuilders not only can improve an OE design, but they can also improve the consumers’ opinion about the rebuilt auto parts business, in general. Many people still believe that all rebuilt parts are sub-standard compared with original equipment parts. However, most rebuilders are continually working to improve the reputation of rebuilt parts by producing quality
Complete Circuit: The Components That Are The Cause Of Most Starter Failures
If you had to categorize the components that are the cause of most starter failures, the starter solenoid, without a doubt would be on top of the list. The starter drive may come in a close second. Some large rebuilders may opt to rebuild their starter solenoids in-house or have them built to their specifications,
Grinding Techniques: In Thousands Of Years, The Basics Of Grinding Haven’t Changed
Grinding is one of the oldest methods known for shaping and sharpening objects. It was first used in prehistoric times to make weapons and other tools by rubbing wood, stones, bones and eventually metal against hard, abrasive rocks. In thousands of years, the basics of grinding haven’t changed. We’re still rubbing an abrasive against metal
What Is The Recommended Surface Finish
Shop Line, Automotive Rebuilder, July 1996 Q A In the Production Engine Remanufacturers Association’s (PERA) May 1996 edition of Current Concerns, Ed Keibler of Sunnen Products Co., St. Louis, MO, says that the typical Ra finish on cast iron should be 60 to 110 Ra. On aluminum cylinder heads it is much smoother – typically
Valve Guide Repair Options
One thing you can almost always count on when rebuilding a cylinder head is worn valve guides. The guides experience a lot of wear because of the constant friction between the guide and stem. To make matters worse, positive valve seals on late model engines prevent the guides from receiving much lubrication. Side forces on
Making Power From Big Block Fords
As noted last month, the first part of a big block Ford power program is to select the appropriate components and machine them properly. Part two entails coordinating the camshaft and valvetrain with an engine’s intended use, and then bolting everything together using proven high performance techniques. According to high performance Ford specialist Norm Wizner,
Machine Shop Performance: This Month We Complete Our Extensive Market Profile
Part I of last month’s profile of the machine shop market revealed that engine production in business year 1995 was almost identical to that recorded in 1994. Based on a universe of 6,000 to 8,000 full-service machine shops, custom engine rebuilders produced between 1.4 million to 1.87 million engines in 1995. Last month’s data provided
