![]() Carefully rotate the crankshaft clockwise until the piston touches the piston stop. Loosen the cam bolt so the cam gear can be pulled off the cam, but still supported on the bolt. Install a piston stop, into the #1 cylinder spark plug hole and tighten. Rotate the crank shaft to position the #1 piston at BDC (bottom dead center). To set true piston TDC (top dead center) on the degree wheel with the cylinder head installed. Position it off of one of the 6mm water pump bolts. Setup Procedures: Install the degree wheel on the crankshaft. This will achieve the most accurate settings available, resulting in the best performance from your engine package. We recommend the Intake Lobe Center Method to degree the camshaft. You will now be able to advance or retard the camshaft timing accordingly. Install the adjustable camshaft gear onto the camshaft with the timing chain and secure. Tighten the nuts on the adjustable cam gear and make a mark (using a chisel) on the outer gear at the ?zero? mark of the adjustable camshaft gear. With the holes in the center hubs lined up, rotate the outer gear of the adjustable camshaft gear to line up with the factory teeth (make sure that the dowell holes on both center hubs still match). Line up the camshaft dowel holes on both gears. Set the factory camshaft gear on a flat surface and place the adjustable camshaft gear on top (make sure that the nuts on the adjustable cam gear are loose first). Be careful to not let the timing chain fall below the timing chain cover. With the #1 cylinder at TDC (top dead center), remove the factory timing gear from the camshaft. Because of the numerous variations in engine mechanics, including cylinder head decking, cylinder block decking, camshaft size, etc., which play an important role in overall camshaft timing, LCE recommends the following in the initial set up of your new adjustable camshaft gear. NOTE: The zero marking on an adjustable camshaft gear is not always in direct correlation with the camshaft centerline. Note: If you do not use the fuel pump drive, you must space the distributor drive gear out the same thickness (0.90?) as the fuel pump concentric or damage will occur to the distributor drive gear. 2) Mark and machine the fuel pump concentric drive to clear the allen head bolts used on the cam gear (machining the concentric drive too deep may cause the drive arm to fall into the machined slots where damage will occur). It is possible to run a Manual Fuel Pump with an adjustable cam gear by doing the following: 1) Remove allen head bolts and turn them around in the cam gear (allen heads outward). For Electric Fuel Pump applications, we recommend using the LC Pro Fuel Pump part # 1035045. Using an LC Engineering Performance Single or Double Adjustable Cam Gear is the only way to accurately degree the camshaft to its proper specifications. 2RZ/3RZ Adjustable Intake Camshaft Gear (95-03), see Part# 1022009.20R/22R Single Row Adjustable Camshaft Gear, see Part# 1022006.20R/22R Dual Row Adjustable Camshaft Gear, see Part# 1022003.
