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. There is nothing magical about the numbers on the cam card or how they were determined. Once you are happy, move to the exhaust and repeat the process. The process ensures that a cam's centerline is in its correct position for your particular engine. Continue down to zero lift and verify that the dial indicator has returned to zero. Always double check measurements and readings. Cam or crank gears are incorrectly marked. Camshaft Degreeing Tool. Precisely etched on both sides with 1° increments. 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. Rigidly mounted pointer to indicate degree wheel position. The Incorrect Method / Myths About the Centerline. The formula to find the centerline of the intake in example ‘C' is, duration divided by two less IVO; 230/2-4 = 111 degrees ATDC, this should match the figure on your spec card, if it doesn't you will need to advance or retard the cam and repeat the procedure until it is correct. Record the degree wheel number that the pointer is on. This complete Cam Degree Kit includes all the parts you need to degree your cam. Therefore, a.002" error in checking height would only affect the degree wheel reading about 1 crank degree as shown in Figure 11. If it does not match, your cam is either retarded or advanced. For mechanical lifter over head camshafts all readings are taken with the valve lash set to the proper clearance as specified by the cam card. The method we use below is the correct method to accurately degree your cam to achieve the proper valve opening and closing events. The High Performance Academy has a courses that covers this specific topic in a huge amount of detail. 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. Continue to rotate the engine in the same direction. Cam Degree Wheel Printable via 99. We apologize for any inconvenience. Home Delivery. Because of camshaft ramp designs the valve events at a lift as low as 0.1mm are often asymmetrical this is why we specify checking valve timing at 1.00mm or .050" (in the case of imperial engines), it is more accurate for most people. Watch the dial indicator. The 24" Laser Degree Wheel provides the ultimate in ease of use, flexibility and accuracy. Now either move the pointer to align with the 18 degree mark on the degree wheel, or carefully loosen the degree wheel (without disturbing the position of the crankshaft) and move the degree wheel to the 18 degree mark, making sure that the piston is still against the stop.

It is accurate to use the valve event figures to determine a centerline number. 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. Turn the engine in the direction of rotation until you reach 1.00mm valve lift on the dial indicator, record the figure on the degree wheel, continue to rotate in proper direction counting up to full valve lift. If your intake is set correctly the exhaust should match the spec card as well unless there is a variation in the separation. the lifter could be sticking slightly in its bore. To walk us through the process, Crower supplied us with Shane Pulido from their tech department. An arc is a shape made of a certain angle which is then used to measure a circle. It is essential at this point that you have some means of rotating the crank that will not interfere with the degree wheel. This method makes the assumption that the lobe or valve motion you are checking is symmetrical; with its opening side being the exact same shape as the closing side of the lobe. We have a great online selection at the lowest prices with Fast & Free shipping on many items! 1-5 of 5 Results. It is important that the indicator plunger be aligned as closely as possible with the lifter being measured, any substantial angle between the axis of the plunger and the lifter will introduce geometrical errors into the lift readings. properly check a cam:(1) An accurate Degree Wheel for the crankshaft. As a triple check, measure the valve lift at TDC, and this should also match the card. Overlap at 1.00mm valve lift from Spec card ‘C' = IVO of 4 degrees BTDC less 2 degrees BTDC = 2 degrees at 1.00mm valve lift. This will include the opening and closing timing points and the amount of lift at the lifter or at the valve (depending on engine type) at which the timing should be checked. Continue to rotate the engine in the same direction (counting down) until you are .050" before closing. SELECT STORE.

For example ‘D' Inlet Opens 8 degrees ATDC, Inlet Closes 38 degrees ABDC the equation is 180-8+38=210 degrees of duration at 1.00mm valve lift. If the degree wheel reads less than 8 degrees, your cam is retarded. If your engine is not listed, please contact us to see if we can make you a custom cam. Therefore 18 degrees from either of your stop points is true top dead center. Once you are happy, move to the exhaust and repeat the process. To find duration, the formula is IVO of 4 degrees BTDC plus 180 degrees to get to BDC plus 46 degrees to the IVC point ABDC; 4+180+46 = 230 degrees of duration at the valve at 1.00mm checking height. All our springs are designed here at Kelford and manufactured exclusively to our specifications using the finest spring wire and latest surface finishing techniques by PAC Racing in the USA. With the cam on the base circle set the dial gauge to zero with enough preload that the gauge is held firmly but not so much preload that you bind the gauge on full lift. Also, the centerline method does not really indicate if your camshaft was properly produced, as no confirmation of the duration at any given point. Rotate the crankshaft until you get number one piston as close as possible to TDC. Note: When degreeing a cam, remember to look at the degree wheel as a full 360˚, no matter how the degree wheel you are using is marked. 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. At this point we check the duration and centerline by adding the Intake Opening (IO) point before TDC plus 180 degrees of crank rotation to get us to BDC plus the Intake Closing (IC) point in degrees ABDC so using the figures on spec card ‘A' we calculate as follows, 24+180+56 = 260 degrees of intake duration at .050" cam lift. Filter. $14.08. BRAND. If you've got aftermarket cams, cam degreeing is essential for optimum performance. We have split the method into two engine types to give proper examples.
