Camshafts are a subject that all car guys love to talk about, and those who listen tend to roll their eyes at the staggering number of terms and numbers. This creates more power. ... Vice versa if you advance the camshaft. Roller cams are more expensive, but also more reliable. After finding camshafts in the Cam Length column, determine camshaft head style, using the Head Styles chart and head width dimensions. Advertised duration on the other hand is not standardized. There’s lift and duration, overlap and lobe centers, lobe separation angles and so on, and all of them have numbers attached. is this standard? There are 4 types of lifters commonly used in engines. The 0.050” measurement is the amount of duration from the point the valve is open 0.050” to the point it is 0.050” from closing. Lobe separation angle is the measurement in degrees between the intake and exhaust lobe centerlines. The cams and the camshaft are usually formed as a unit, with the cams set at angles so as to open and close the valves in a When the lobe reaches its highest displacement … At the end of a roller cam lifter, as the name suggests, you’ll find a rolling cylinder, which the lobe pushes up with reduced friction as it rotates. There is a limit to the amount of air an engine can move and opening the valve further than needed becomes counterproductive. Because you need at least one camshaft per cylinder bank, inline engines need as few as a single camshaft, whereas a V arrangement would require at least two. The cam companies all have their own "grind numbers". The roller cam will have much more rounded lobes, like the big end of an egg. Comp Cam Identification Numbers. Gene Stoehr. It also allows more exhaust to escape. Using a Dial Indicator and Degree Wheel, find the opening and closing points of the valves at 0.050 in. Step 15: Remove the camshaft gear. Optional camshaft number requirements are listed at the link in Resources. Step 16: Install the camshaft gear onto the new camshaft. Thanks author: message: admin. Part number is 100172 which really tells you nothing. He holds a bachelor's degree in criminal justice from Indiana University, and resides in Northwest Indiana. A number of factors influence valve lift. Depending on the model of vehicle, you may also need an exhaust grind number, which will be stamped onto your car's exhaust inlet, and it will follow the same form as the numbers on the camshaft. For example, you might have a camshaft stamped with the numbers 899C, followed by various numbers with degrees. For example, you might have a camshaft stamped with the numbers 899C, followed by various numbers with degrees. Advertised duration on the other hand is not standardized.

You must always use the lifter type that the cam was ground for as each lifter type requires a unique camshaft design. Overlap creates lower cylinder pressure and a rougher idle (bumpity bumpity). ... the camshaft had some weird numbers that I can not identify. The most important being the gap between the intake and exhaust valves, the piston to valve clearance and the intake charge pressure. Narrow your final selection by Diameter at Spline End and Number of Splines, Diameter at Spider and any other information listed. – 0.500” commonly referred to as 500 lift. As mentioned before the intake and exhaust lobes each have their own design and therefore may be different. In the image on the left is a hydraulic roller cam, the rounded lobes are readily appearant compared to the flat tappet cam to the right of it. These are called dual profile camshafts (sometimes dual grind). However, if you break the number down one piece at a time, it becomes easier to identify. Be aware that the more you open the valve the closer it is to the piston. Lobe lift refers to the distance that the camshaft can move the pushrod in turn “lifting” the valve off of the seat (opening the valve). Meanwhile, a spring exerts a tension pulling the valve toward its closed position. Even though the stock cam has a duration of about 250 degrees, a mild aftermarket cam like the Engle 100 (duration 270 degrees) will still move the point of maximum torque/horsepower further up the RPM range. camshaft application chart notes: comments mech/ dur @ .050” adv. How To Identify Gm Camshafts . This requires a little more time but … … Take the 899C and add it to the model prefix. The camshaft consists of a cylindrical rod running the length of the cylinder bank with a number of cams (discs with protruding cam lobes) along its length, one for each valve. Telling one from the other visually is relatively easy. These are called dual profile camshafts (sometimes dual grind). Mechanics consider a small amount of end play acceptable, since it permits the camshaft to shift in relation to temperature gain. Camshaft basics explained. This number is ground into the cam and can't be altered without physically changing the camshaft lobe profiles. How To Identify Camshaft Numbers CAMSHAFT QUICK IDENTIFICATION GUIDE *Axle Type: S = Steer, D = Drive, T = Trailer Diameter at Spline Diameter Spicer Cam Head End & No. His experience includes comics, role playing games and a variety of other projects as well. This can be altered by degreeing the cam after it's been installed in the engine. The roller cam will have much more rounded lobes, like the big end of an egg. Roller camshafts, on the other hand, must take end play into account. Do not rotate camshaft or crankshaft with timing belt removed and cylinder head fitted. Warning: When removing the camshaft, you want to make sure that it does not fall, as it can damage the bearings in the cylinder head. However, if you want to find the duration for the camshaft in your engine, you can calculate it. No matter which camshaft you choose remember, Wrench…Drive…Enjoy…. There is one lobe for every valve in the engine with the intake and exhaust lobes each having its own design. The lobes machined into the camshaft are the magic sauce that can make or break an engine. How To Identify A Camshaft. This information is required to calculate the ignition point and injection point, among other things. With a W16 to keep in shape, the Veyron employs a quad-cam setup with a total of 64 lobes. A low duration camshaft works best at lower RPMs. Cam companies use the intake centerline of cylinder No. Most Cam Cards will list duration. The camshaft sensor enables the engine control to determine the exact position of the crankshaft drive. note: the above cams can be used in the 351w & 302 high output engines by rewiring the distributor to firing order 1-5-4-2-6-3-7-8. roller camshafts for engines originally equipped with roller cams mc24226 hyd 3 212 222 289 300 .491 509 107 117 2800-5000 fair 2205 b, n Duration @.050" is a measurement of the movement the cam follower, in crankshaft degrees, from the point where it’s first lifted .050" off the base circle on the opening ramp side of the camshaft lobe, to the point where it ends up being .050" from the base circle on the closing ramp side of the camshaft lobe. In addition, a small amount of end play allows the cams to better resist wear by shifting their position in response to especially hard contact. For instance, the number for a Toyota 3SGE would be CS 3SGE. In piston engines, the camshaft is used to operate the intake and exhaust valves.The camshaft consists of a cylindrical rod running the length of the cylinder bank with a number of cams (discs with protruding cam lobes) along its length, one for each valve.A cam lobe forces a valve open by pressing on the valve, or on some intermediate mechanism, as it rotates. 3. This is especially true with flat tappet lifters. Typically camshaft manufacturers list this measurement by multiplying the cam lobe lift by the stock rocker arm ratio, usually 1.5:1. A cam lobe forces a valve open by pressing on the valve, or on some intermediate mechanism, as it rotates. Find the profile or grind number. The 7661-11 is a serial number specific to that camshaft only. Re: Where can i find camshaft Id Numbers . Without a properly designed camshaft, the air pump we call an engine would be useless. Rocker arm design also plays a part in the total lift based on its ratio. The ID number will consist of either eight or nine digits; the last four numbers identify the cam and its specific application. I have a "CWC" stamping.... Camshaft Spec Card Search - … The cam's centerline specification is used to determine the position of the lobes on both the cam and as installed in the engine. The shape, size and placement of these lobes control the engines ability to function efficiently in turn creating more power. Die Messuhr auf das Ende der Nockenwelle nullen. The 0.050” measurement is the amount of duration from the point the valve is open 0.050” to the point it is 0.050” from closing. For example, if your cam lobe lift is .319 and you're using a 1.5:1 rocker arm ratio, you can take .319 x 1.5, which is .479 inches of overall valve lift. I believe what I have should be 2 Desoto Cams and one either dodge, or chrysler. However, at low rpm, the open valves reduce the pumping pressure of the piston. Ted Eaton responded and thought my cam was a Melling Cam. Duration @.050" is a measurement of the movement the cam follower, in crankshaft degrees, from the point where it’s first lifted .050" off the base circle on the opening ramp side of the camshaft lobe, to the point where it ends up being .050" from the base circle on the closing ramp side of the camshaft lobe. My handle is Rudder2fly. Less duration tends to produce more low end torque with a better idle but reduces the ability to make power in the upper rpms. The ID number will consist of either eight or nine digits; the last four numbers identify the cam and its specific application. The main focus of this article will be on a conventional OHV (overhead valve), cam-in-block engine configuration using two valves per cylinder, as shown above. 114* LSA . i pulled apart an a14 bottom end for rebuild and noticed it had been tampered with before. This also refers to the term overlap which is the amount of time both the intake and exhaust valves on one cylinder are open at the same time. I Can't seem to find enough numbers to make a complete ID number. More on that another day. The camshaft is an important part of your vehicle; it helps certain elements of your car run smoothly, from regulating the timing of your valves to bringing in fresh air to kick out exhaust. Lobe Shape. In the image on the left is a hydraulic roller cam, the rounded lobes are readily appearant compared to the flat tappet cam to the right of it. Randomly choosing a camshaft profile usually has lackluster results without lots of research and practice. Hydraulic flat tappet, solid flat tappet, hydraulic roller and solid roller. A camshaft with 106 degree lobe separation angle will have more overlap than one with 112 degrees. Duration is measured in degrees and refers to how long the valve event (valve open) lasts. A rough estimate is a 4 degree change in cam phasing will change the cranking pressure by 5 psi (advancing increases pressure, retarding decreases pressure). Neal Litherland is an author, blogger and occasional ghostwriter. Copyright 2021 Leaf Group Ltd. / Leaf Group Media. More bottom end, less top end. If you reuse lifters you will quickly destroy the lifters, camshaft lobes or both. Cam timing at .050" is: intake opens 1 degree BTDC, intake closes 41 degrees ABDC, exhaust opens 50 degrees BBDC, exhaust closes 8 degrees BTDC. A flat tappet cam will be much more pointed, similar to the small end of an egg. These factors also influence cam duration. Camshaft designs are called profiles and today we are going to look at what makes a profile. The most extreme camshafts come in the shape of those featured on the Bugatti Veyron. Take the 899C and add it to the model prefix.
