The basic tools required are a degree wheel, a stable pointer that can be mounted to the engine, a dial indicator with at least one inch of travel in.001" increments, a stand that mounts it to the engine, and a positive stop device to locate TDC. Heavy gauge aluminum discs calibrated in 1° increments for determining precise valve, cam and ignition timing. 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. 11" diameter. Use this formula to check that your measured duration matches your spec card. Turn the engine in the opposite direction until the piston comes back up and touches the piston stop again. 99. Find an Automotive Service Professional near you. 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. For example: Let's say that the stop points are 16° in one direction and 20° in the opposite direction. We have split the method into two engine types to give proper examples. Depending on the engine being used, there are usually offset bushings, offset keys, or multi-indexed gears to accomplish this movement. Precisely etched on both sides with 1° increments. Record the cam lobe lift, this should match the cam lift figure on your spec card (.350" in the example of Spec card ‘A'). The page you requested could not be opened or has moved. To find total overlap, check valve timing at 0.1mm valve lift as a checking height, if the valve motion is symmetrical at that lift, our example spec card cam which has a intake duration of 270 degrees and an exhaust duration of 256 degrees at 0.1mm will have valve timing events of IVO 24 BTDC / IVC 66 ABDC - EVO58 BBDC / EVC 18 ATDC giving an overlap of 24+18= 42 degrees. It tells the engine where to make power,” Pulido says. Continue to rotate in proper direction, counting down from full lift until you are 1.00mm away from fully closed, record the degree wheel figure. The method we use below is the correct method to accurately degree your cam to achieve the proper valve opening and closing events. Our method will verify correct valve opening and closing and duration. 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. While i… JEGS Precision Cam Degree Wheel Kit | 11” Diameter Wheel | Made in USA | 3/4 “ Center Hole | Includ… order. 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. JavaScript seems to be disabled in your browser. It is accurate to use the valve event figures to determine a centerline number. Also, the velocity (rate of cam lift) of most camshafts is approximately.004" per cam degree at.050' lifter rise. On wheels that are marked in 90° increments, keep in 99. Diameter, Includes Adapter Inserts for 7/16 in., 1/2 in., 5/8 in. COMP CAMS HELP™ 901-795-2400. SELECT STORE.

We have a great online selection at the lowest prices with Fast & Free shipping on many items! Adjusting the intake and exhaust cam timing allows the builder to move the torque curve to increase peak torque or peak horsepower. 99. It is essential at this point that you have some means of rotating the crank that will not interfere with the degree wheel. This is easiest done by pulling the plunger out of a hydraulic lifter and replacing it with a piece of turned silver steel (or similar) that sits properly inside the lifter body and is shaped at the valve end to clear the retainer and give a perfect flat contact to the valve tip. Record the full valve lift figure; this should match the figure on your spec card. Most modern cam lobes are asymmetrical, with the opening side of the lobe being much more aggressive and the closing side being gentler. By specifying a Kelford Spring in your build you are selecting the highest quality product designed to be part of an integrated solution that will maximise performance and protect your investment. Repeat the procedure above until you get the same amount of degrees on both sides of TDC. Camshaft Degreeing Tool. 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. SKU # 750906 $ 169. Skip to the beginning of the images gallery . 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. Qty. BRAND. Their size allows you to use them on the engine stand, or with the engine still in the vehicle. Next, adjust your pointer to the zero TDC position on the degree wheel. The opening and closing figures should be within ±1 degree. (4) A Top Dead Center Piston Stop. It will include Cam lift, rocker ratio, Net valve lift, valve lash (tappet clearance) and more. 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. Watch the dial indicator; it will change direction at maximum lobe lift. 99. The cam has got to be installed 100-percent accurately for it to make power where it should.”As mentioned in the opener, the idea that you need a drawer full of super-specialized tools to degree a camshaft in the engine is false. To walk us through the process, Crower supplied us with Shane Pulido from their tech department. Please select your engine model below to view our range of catalogue camshafts. SKU.

The advance recommended by the cam grinder is probably just an educated guess. On SOHC rocker arm style engines, valve tip length, rocker geometry and base circle size will effect lobe separation, therefore effecting valve events. Continue to rotate the engine in the same direction. Always double check measurements and readings. Crane Cams 99162-1 - Crane Cam Degree Wheels Degree Wheel, 9 1/2 in. 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. Rotate the crankshaft until you get number one piston as close as possible to TDC. 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. “The camshaft is essentially the brain of the engine. 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. If your engine is not listed, please contact Us. All Metric Inputs in Millimetres (unless otherwise noted) Positive stop TDC finding tool (either the spark plug type or a block mounted type), 4. To find the centerline figure the equation is: Duration divided by two, plus the Inlet Opening point example ‘D' would then be: 210/2+8= 113 ATDC centerline. (In our example spec card ‘A' it is 24° BTDC). Howards Cams, Professional Degree Wheel, 14, 2-SidedBR Not stamped, but CNC machined billet aluminum for accuracy. Part # 68786. Home Delivery. (In example ‘A' it is 56° ABDC). As a triple check, measure the valve lift at TDC, and this should also match the card. Many degree wheels are marked in 90° or 180° increments. Add to Cart. Using spec card C we have an Exhaust Valve Opening (EVO) of 38 degrees BBDC and an Exhaust Valve Closing (EVC) of 2 degrees BTDC, the equation is 38+180-2 = 216 degrees of exhaust duration at 1.00mm valve lift. 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. SKU # 750979 $ 119. Part No: DGW-1 DGW, DGW1. If it doesn't return to zero, there are several possible causes: the dial indicator may not be mounted rigidly, the lifter may not be contacting the base circle properly. Such as: Thus properly degreeing your cam is essential. Lifter Setup InstructionsBe absolutely certain that you use the correct type of lifter for the camshaft that is being Degreed. $171.52.

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. For pushrod style engines mount the dial gauge to something solid that won't flex or move. Go through the procedure again until you are within one degree of where you want to be (preferably on the advanced side if anything to allow for chain / belt stretch during operation). To learn a circular arc, you can search for a template with the keyword "360-degree wheel printable" so that it can make it easier for your child to learn about circular measurement. 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. Email. We apologize for any inconvenience. Center Holes, Each Part Number: CRN-99162-1 (3) The process ensures that a cam's centerline is in its correct position for your particular engine. Either your session has timed out or the page does not exist. Cam or crank gears are incorrectly marked. 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. Clay Smith Cams highly recommends degreeing the camshaft whenever you install a new cam or replace the timing chain. At Kelford our springs have been designed to be part of an engineered solution that takes into account the intricacies and unique requirements of each camshaft profile to create an engineered solution that maximises power output while ensuring valve train integrity. 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.
