Camshaft Installation and Break-In Tips
Do not attempt to operate an engine with less than .150? retainer-to-guide clearance. If you are using valve seals, check the clearance from the top of the seal rather than the top of the guide. When using a flat tappet camshaft and high pressure valve springs with more than 130 lbs of seat load or
Inside Flat Tappet Camshaft and?Lifter Technology
Roller cams have a couple of advantages over traditional flat tappet camshafts: they reduce friction, and they can be ground with more aggressive cam lobe profiles to make more power. You can also swap roller cams without having to replace the lifters. But the roller cam’s main disadvantage compared to flat tappet cams is its
Flat Tappet Camshaft Break-in Procedure
Note: New lifters must be installed with your new camshaft prior to Installation: • Check the compatibility of the camshaft with the remainder of the valve train components (valve springs, rockers, etc.) • On race type, high spring load applications, use lighter load springs or remove the inner spring (dual spring application) just for break-in.
PBM To Host Camshaft Design and Development Seminar at PRI
Noted speakers Steve Tanzi of Erson Cams and Darin Morgan of Profiler Performance will moderate an open discussion about cylinder head airflow and camshaft performance. Morgan and Tanzi will focus the discussion around how cylinder heads are affected by camshaft lift and duration and other factors that influence today’s racing heads and cams. Darin Morgan
Diesel Performance: Camshafts, Lifters and Valvetrain
Diesel performance is nothing new. What is new is the level of interest in diesels for all kinds of racing; everything from traditional truck and tractor pulling to drag racing, even sports car and endurance racing. Diesel engines are a different type of animal when compared to gasoline engines. While both use the same four-stroke
How to Degree A Camshaft

New Camshaft Microfinishing and DLC Application Services for U.S. Market
Bekaert Diamond-Like Coatings recently installed a high energy centrifugal barrel micro-polishing machine for camshaft polishing. The machine will enable Bekaert to give camshafts the ideal pre-coating treatment, to ensure optimal smoothness of the surface before applying the black DLC coatings. Additionally, Bekaert will also service customers who are not looking to apply DLC coatings, but
Rattle or Knocking Noise from Audi Camshaft Adjuster at Cold Start
The following chart lists the production models and engines affected by this conditon. Service The camshaft adjustment is hydraulically actuated and controlled by the engine oil pressure. If the engine has been turned off for a longer time, the oil pressure drops down and the
Howards Cams Completes Purchase of Custom Camshaft Co.
The purchase fof CCC will enable increased production capacity and new production capabilities, according to a spokesman for Howards Cams. Engine builders will now have even more options for custom grind development. Included in the assets of the purchase is a Landis 3L CNC cam-grinding machine, a well regarded name in cam grinding equipment. According
Why Do Camshafts Fail?
Here’s a list of common mistakes we have determined to cause camshaft failure: 1. Lobe Wear Use only the manufacturer recommended lubricant, which is generally included with the cam. This lubricant must be applied to every cam lobe surface, and to the bottom of every lifter face of all flat tappet cams. Roller tappet cams
Camshaft Ticking Noises on some 3.0L 4V Ford Duratec Engines
Some 2005-2007 Five Hundred, Freestyle, Montego, and 2006-2007 Fusion, Milan, 2006 Zephyr, 2006-2008 Escape and Mariner vehicles built 1/17/2006 thru 5/31/2007, equipped with the Ford 3.0L 4V Duratec engine with exhaust camshaft driven water pumps may exhibit a ticking noise from the left bank cylinder head with the engine at normal operating temperature.

Properly Matching Your Camshaft and Distributor Gear
Matching camshaft and distributor gears is one of the most critical, yet often overlooked step in engine assembly. The proper distributor gear for your camshaft differs by both the material and the kind of lifter for which your camshaft was designed. Using the wrong material can lead to premature gear wear, possible camshaft wear and
1998-2002 Honda 3.2L V6 Camshaft Subgear Preloading
The1998-2002 Honda Passport (3.2L) V6 engine has a “non-interference”design. This means the valves never contact the pistons, even when thevalves or camshafts are not correctly timed, or even if a valve isfully open and its piston is at top dead center (TDC). • The ratio between the camshaft drive gear and the camshaft gears is1.33
Choosing A Replacement Camshaft
Unless you are doing a totally stock rebuild and reusing the original camshaft, selecting a camshaft depends on what kind of engine you are building and how that engine will be used. A stock engine for a daily driver is obviously an entirely different application than an big stroker motor for a Pro Stock racer.
