So it can be said that the arc is part of a circle. Most modern cam lobes are asymmetrical, with the opening side of the lobe being much more aggressive and the closing side being gentler. FILTER RESULTS. Never use the ‘centerline' method that zeros somewhere near full lift and then splits the difference between two readings on the degree wheel either side etc, this is not accurate. Degree Wheel. Home Delivery. Therefore, a.002" error in checking height would only affect the degree wheel reading about 1 crank degree as shown in Figure 11. Enchance your email experience by providing your zip code for area specific offers. Incoming intake charge or outgoing exhaust does not care where the centerline is, they only respond to filling or evacuating the cylinder based on relevant valve opening and closing events. Before You Start To Degree Your CamAssuming that you have carried out all of the preliminary static measurements and clearance checks for valve to valve, valve to piston, retainer to stem seal, cam to head casting, cam to con-rod, spring seat pressure, distance to coil bind at full lift etc, all parts are clean, and lightly oiled you are ready to start dialing in your camshaft.The best place to start is to install your cam on factory marks using the engine manufacturer's procedure. Super heavy-duty construction and precision design mean this is a "Hands-On" tool that makes the cam dial-in process faster and less complicated. “The camshaft is essentially the brain of the engine.

Therefore when you attempt to locate the middle (or centerline) of the asymmetrical lobe there is an automatic error. Set intake and exhaust cam timing accuracy on your motorcycle, ATV or UTV with a Hotcams Cam Degree Kit. To find the centerline figure the equation is: Duration divided by two, plus the Inlet Opening point example ‘B' would then be: 220/2+5= 115 degrees ATDC centerline. Make a note of what degree the pointer is on the degree wheel. 99. This site uses cookies. Record the full valve lift figure; this should match the figure on your spec card. By continuing to browse this site you are agreeing to our use of cookies. A Simple Explanation of Cam Degreeing In simple terms, the Degreeing process can be thought of as using a dial indicator and degree wheel as tools to map out one revolution around the cam lobe. If the camshaft has a short duration and / or late valve events like the one in the example spec card ‘B", the Intake Opening point could be ATDC in which case the equation to find duration is: 180 degrees from TDC to BDC, less the Intake Opening point in degrees ATDC plus the Intake Closing point in degrees ABDC. Skip to the beginning of the images gallery . the lifter could be sticking slightly in its bore. Is to achieve the correct valve opening and closing points for your engine.All of our new camshafts are ground to exact specification using the latest CNC machining processes but there are other factors that can cause incorrect camshaft to crankshaft phasing. If you've got aftermarket cams, cam degreeing is essential for optimum performance. While i… Heavy gauge aluminum discs calibrated in 1° increments for determining precise valve, cam and ignition timing. Once you are satisfied that the intake is correct move to the exhaust and repeat the process.

Using spec card D we have an Exhaust Opening (EO) of 46 degrees BBDC and an Exhaust Closing (EC) of 8 degrees BTDC, the equation is 180-8+46 = 218 degrees of exhaust duration at 1.00mm valve lift, to find the centerline as a double check, the formula is duration divided by two plus exhaust opening; 218/2+8 = 117 degrees BTDC. Home Delivery. You must have JavaScript enabled in your browser to utilize the functionality of this website. Proform 9in Camshaft Degree Wheel Kit with Heads Off $ 119. If the duration matches but the centerline figure and open and close events do not, you will need to advance or retard the cam to achieve the correct result. Rotate the engine slowly in the proper direction of rotation and make sure that the dial gauge moves freely up and over full lift and back to the zero position. An arc is a shape made of a certain angle which is then used to measure a circle. Hydraulic lifters must never be used when degreeing cams, they can bleed down and give you false readings.For Pushrod style engines this is easy, if your camshaft choice is hydraulic roller or hydraulic flat tappet, simply purchase a solid equivalent of your lifter. JEGS Precision Cam Degree Wheel Kit | 11” Diameter Wheel | Made in USA | 3/4 “ Center Hole | Includ… Howards Cams, Professional Degree Wheel, 14, 2-SidedBR Not stamped, but CNC machined billet aluminum for accuracy.

Install a pushrod that has an oil hole in it, so that the tip of the dial indicator locates properly in the end of the pushrod.For over head cam engines that have hydraulic cam buckets, such as Nissan RB20 or Suzuki G13B or for over head cam engines with rocker arms and hydraulic lifters, such as Mitsubishi 4G63 or Nissan SR20, you will need to make a solid lifter that gives 0.1mm valve clearance when the cam is on the base circle. Depending on the engine being used, there are usually offset bushings, offset keys, or multi-indexed gears to accomplish this movement. Continue down to zero lift and verify that the dial indicator has returned to zero. Such as: Thus properly degreeing your cam is essential. If the camshaft has a short duration and / or late valve events like the one in the example spec card ‘D", the Intake Opening point could be ATDC in which case the equation to find duration is: 180 degrees (from TDC to BDC), less the Intake Opening point in degrees ATDC plus the Intake Closing point in degrees ABDC. It will include Cam lift, rocker ratio, Net valve lift, valve lash (tappet clearance) and more. This figure should match the duration figure on your spec card, 260 degrees divided by two less the intake opening gives you the centerline number that should match your spec card e.g. 99. The crank can be rotated from either the front or the flywheel end. Adjusting the intake and exhaust cam timing allows the builder to move the torque curve to increase peak torque or peak horsepower. Once you are happy, move to the exhaust and repeat the process. Using spec card A we have an Exhaust Opening (EO) of 63 degrees BBDC and an Exhaust Closing (EC) of 27 degrees ATDC, the equation is 63+27+180 = 270 degrees of exhaust duration at .050" cam lift, to find the centerline as a double check, the formula is duration divided by two less exhaust opening; 270/2-27 = 108 degrees BTDC. (See V to P instruction), For these types of engines, Kelford Cams spec cards list duration, opening and closing events at the valve (unless otherwise stated by us), The setup procedure is the same as listed above except that the dial gauge will often need a long extension to reach down beside the cam lobe to contact either the spring retainer (in the case of a rocker arm engine) or the cam bucket (in the case of a direct bucket OHC engine).
