24" Laser Degree Wheel. 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. The crank can be rotated from either the front or the flywheel end. Depending on the engine being used, there are usually offset bushings, offset keys, or multi-indexed gears to accomplish this movement. 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. Qty. Attach the pointer to the engine ensuring that it is rigid and won't move if you accidentally bump it. properly check a cam:(1) An accurate Degree Wheel for the crankshaft. You can sit down with a degree wheel and dial indicator and determine everything you need to know to set up your camshaft (click on photo to enlarge). While i… Shane Pulido of Crower walks us through not only the "how" of properly degreeing a camshaft, but the "why" as well. You must have JavaScript enabled in your browser to utilize the functionality of this website. Skip to the beginning of the images gallery . We have split the method into two engine types to give proper examples. The greater the leverage, the smoother you can rotate the crank for timing checks. order. Repeat the procedure above until you get the same amount of degrees on both sides of TDC. It is accurate to use the valve event figures to determine a centerline number. Record the full valve lift figure; this should match the figure on your spec card. Home Delivery. JEGS Precision Cam Degree Wheel Kit | 11” Diameter Wheel | Made in USA | 3/4 “ Center Hole | Includ… Proform 16in Universal Camshaft Degree Wheel $ 169. Again record the degree wheel number that the pointer is on. 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. Set intake and exhaust cam timing accuracy on your motorcycle, ATV or UTV with a Hotcams Cam Degree Kit. Camshaft Degreeing and Measuring Tools, Moroso, 11 inch Degree Wheel, Moroso, 18 inch Pro Series Degree Wheel, Proform, Universal Degree Wheel Kit, Comp Cams, Crankshaft Socket for Degree Wheels Part Number: TFS-90000-16 PROFORM's Professional 16" Billet Aluminum Degree Wheel is for the serious engine builder and tuner. 1-5 of 5 Results. Center Holes, Each Part Number: CRN-99162-1 (3) Use this formula to check that your measured duration matches your spec card. The opening and closing figures should be within ±1 degree. Adjusting the intake and exhaust cam timing allows the builder to move the torque curve to increase peak torque or peak horsepower. 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. The process ensures that a cam's centerline is in its correct position for your particular engine. Watch the dial indicator. 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. Our method will verify correct valve opening and closing and duration. 1-5 of 5 Results. Attach the degree wheel to the flywheel or to the front pulley of the engine ensuring that you still have a method of manually rotating the engine. Turn the engine in the opposite direction until the piston comes back up and touches the piston stop again. The 24" Laser Degree Wheel provides the ultimate in ease of use, flexibility and accuracy. Precisely etched on both sides with 1° increments. Clay Smith Cams highly recommends degreeing the camshaft whenever you install a new cam or replace the timing chain. 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. 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. (In example ‘A' it is 56° ABDC). If you've got aftermarket cams, cam degreeing is essential for optimum performance. Part No: DGW-1 DGW, DGW1. In the HPA “How to Degree a Cam” course you will learn a 6 step process to easily dial in any cam and any engine. SELECT STORE. SKU. Free In-Store or Curbside Pick Up. All Metric Inputs in Millimetres (unless otherwise noted) ADD TO CART. This figure divided in half would be 18 degrees. So it can be said that the arc is part of a circle. 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. To get 50% OFF use the coupon “GH1XHR“ at checkout, making the course just $24.50USD. It is essential at this point that you have some means of rotating the crank that will not interfere with the degree wheel. The easy to read display maintains 0.1 degree of crank position accuracy while … Camshaft Degreeing Tool. This site uses cookies. Such as: Thus properly degreeing your cam is essential. 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. Continue down to zero lift and verify that the dial indicator has returned to zero. It will include Cam lift, rocker ratio, Net valve lift, valve lash (tappet clearance) and more. If your intake is set correctly the exhaust should match the spec card as well unless there is a variation in the separation. 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. 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.
