[. . . ] A U T O T E C H Installation Instructions Part Number: Description: 10. 109. 401K ADJUSTABLE CAM SPROCKET, A1/A2/A3 8-valve www. autotech. com Notes: Advancing the sprocket will increase low end (low RPM) performance, while retarding the sprocket will help the top end performance. [. . . ] With the ignition key out of the car, and the car in neutral, take a wrench and turn the stock timing belt sprocket to the zero position lining up with the marks on either the cam cover or cylinder head as found in the instructions for finding Top Dead Center in your Volkswagen repair manual. With the large wrench, remove the center bolt on the sprocket and carefully slide the sprocket off the camshaft end without moving the timing belt. Install the adjustable cam sprocket with the TDC locating mark in the same position as the stock one was when you removed it. Install the bolt torquing it to factory specs (58ft. /lbs. ) Use Loctite on this bolt!Loosen the five flange head screws in the slotted holes so that the plate can slide, then relocate it to the position of your choice. With a large wrench on the center bolt that holds the sprocket on, move the plate so the mark you are selecting is in alignment with the mark on the outer "Black" gear. Locating the timing mark on the black part of the sprocket from "0" clockwise or to the "R" side of the sprocket "retards" the camshaft in single degree increments up to 10 degrees. Moving in the opposite direction "advances" the camshaft timing. [. . . ] It is a good idea to leave the upper timing belt cover off temporarily, while you test changes on the cam timing to suit your driving needs. 32240-E Paseo Adelanto, San Juan Capistrano, CA 92675 Phone 949. 240. 4000 Fax 949. 240. 0450 [. . . ]
