  • Installation Instructions Cloyes® 3-Keyway Crank Sprockets
    February 2, 2009 Installation Instructions Cloyes ® 3-Keyway Crank Sprockets The Cloyes® Patented 3-Keyway crank sprocket allows adjustment of the crankshaft timing by ± 4°. Remember: The camshaft angle is half of the crankshaft angle, therefore the camshaft will correspondingly advance or retard by ± 2°. By changing the cam timing, enhancements to the camshaft characteristics can be achieved. For example, retarding the cam timing will increase high RPM horsepower, and advancing the cam timing will increase low-end torque. The following examples illustrate which timing mark is used with its corresponding keyway: GM and Chrysler Ford Retard keyway To retard the camshaft timing, use the timing mark on the crank sprocket and the retard keyway shown above. GM and Chrysler Ford Factory keyway For factory specified timing, use the Ο timing mark on the crank sprocket and the factory keyway shown above. GM and Chrysler Ford Advance keyway To advance the camshaft timing, use the ∆ timing mark on the crank sprocket and the advance keyway shown above. Notes: After determining which setting to use, we advise marking (with white marker or similar) the corresponding timing mark and keyway. This will make them easier to identify during installation. Some high performance camshafts are ground with advance or retard built in. In this case the cam manufacturer intends the cam to be set at the factory specified timing. Also, during and after installation, observe for any interference between the timing set and engine block. If interference is found, remove or grind that area of the block so adequate clearance is obtained. When removing a press fit crank sprocket, a proper pulling tool should be used.

  • 1. Turn the Crankshaft Clockwise (Right Turn) to Align Each Timing Mark and to Set the Number 1 Cylinder at Compression Top Dead Center
    1. Turn the crankshaft clockwise (right turn) to align each timing mark and to set the number 1 cylinder at compression top dead center. 2. Loosen the tension pulley fixing bolt. CAUTION: If the timing belt is to be re-used, use chalk to mark (on its flat side) an arrow indicating the clockwise direction. 3. Place a screwdriver against the tensioner pulley and pry it fully back in the direction of the arrow. 4. Temporarily tighten the tensioner pulley bolt. 5. Remove the timing belt. INSTALLATION SERVICE POINTS ]]A[[ TIMING BELT INSTALLATION CAUTION: After installing the timing belt, try to rotate the camshaft sprocket in the reverse direction. Recheck to be sure that the belt is fully tensioned and that each timing mark is in the proper position. 1. With the timing belt tensioner pulley bolt loosened, use a screwdriver to pry the tensioner pulley as close to the engine mount as possible. Then temporarily tighten tensioner bolt. 2. Align each of the camshaft and crankshaft sprocket timing marks. 3. Install the timing belt in the following order, while making sure that the tension side of the belt is not loose. 1) Crankshaft sprocket 2) Water pump sprocket 3) Camshaft sprocket 4) Tensioner pulley ]]B[[ TIMING BELT TENSION ADJUSTMENT 1. Initially loosen the fixing bolt of the tensioner pulley fixed to the engine mount side by 1/4 - 1/2 turn , and use the force of the tensioner spring to apply tension to the belt. CAUTION: As the purpose of this procedure is to apply the proper amount of tension to the tension side of the timing belt by using the cam driving torque, turn the crankshaft only by the amount given below.

  • Camshaft Installation and Degreeing Procedure
    1 INSTRUCTIONS Camshaft Installation and Degreeing Procedure Thank you for choosing COMP Cams® products; we are proud to be your manufacturer of choice. Please read this instruction booklet carefully before beginning installation and also take a moment to review the included limited warranty information. This instruction booklet is broken down into several categories for ease of use. Some of the topics may not apply to every application, but all of the information will be very beneficial during the cam installation process. For step-by-step visual detail, it is recommended to watch the COMP Cams® DVD “The Proper Procedure to Install and Degree a Camshaft” (Part #190DVD). If you have any questions or problems during the installation, please do not hesitate to contact the toll free CAM HELP® line at 1-800-999-0853, 7am to 8pm CST Monday through Friday, 9am to 4pm CST Saturday. Important: In order for your new COMP Cams® camshaft to be covered under any warranty, you must use the recommended COMP Cams® lifters and valve springs. Failure to install new COMP Cams® lifters and valve springs with your new cam can cause the lobes to wear excessively and cause engine failure. If you have any questions about this application, please contact our technical department immediately. Camshaft Installation Procedure 1. Prepare a clean work area and assemble the tools needed for the camshaft installation. It is suggested to use an automotive manual to help determine which items must be removed from the engine in order to expose the timing chain, lifters and camshaft. A good, complete automotive manual will save time and frustration during the installation.

Previous testing of SCT engines has shown promise for reduced emissions and fuel consumption, while maintaining performance. The primary goal of this thesis was to complete an EPA 5 Mode emissions test of the parallel rotary synchronous charge trapping (PR-SCT) engine along with defining its maximum performance, as all previous testing had been completed at low load operating points.

  • Basic 2 Stroke Tuning
    Basic 2 stroke Tuning Changing the power band of your dirt bike engine is simple when you know the basics. A myriad of different aftermarket accessories is available for you to custom tune your bike to better suit your needs. The most common mistake is to choose the wrong combination of engine components, making the engine run worse than stock. Use this as a guide to inform yourself on how changes in engine components can alter the powerband of bike's engine. Use the guide at the end of the chapter to map out your strategy for changing engine components to create the perfect power band. TWO-STROKE PRINCIPLES Although a two-stroke engine has less moving parts than a four-stroke engine, a two- stroke is a complex engine because it relies on gas dynamics. There are different phases taking place in the crankcase and in the cylinder bore at the same time. That is how a two- stroke engine completes a power cycle in only 360 degrees of crankshaft rotation compared to a four-stroke engine which requires 720 degrees of crankshaft rotation to complete one power cycle. These four drawings give an explanation of how a two-stroke engine works. 1) Starting with the piston at top dead center (TDC 0 degrees) ignition has occurred and the gasses in the combustion chamber are expanding and pushing down the piston. This pressurizes the crankcase causing the reed valve to close. At about 90 degrees after TDC the exhaust port opens ending the power stroke. A pressure wave of hot expanding gasses flows down the exhaust pipe.
