Due to the higher thermal expansion rate of the aluminum timing cover compared to the steel cam button assembly, there will be a small amount of endplay increase with the engine warmed up. Now, install the locking screw and tighten using a 5/32″ Hex Wrench, to 120 in-lb (10 ft-lb). Using your screwdriver, turn the Quick Button® cam thrust button clockwise until it bottoms against the nose of the camshaft then back it off (turn counter clockwise) 1/8 of a turn. Remember that the screws are going into aluminum, so please do not over-tighten them. Tighten the screws snugly using the 5/32″ Hex Wrench (about 30 in-lbs). Tighten the screws alternately in a crossing pattern until the adapter plate is fully seated in the cover. Insert the four Button Head Cap Screws to hold the adapter plate in place. Install the adapter plate into the access hole in the timing cover with the recessed area of the adapter plate should be towards the top of the engine for proper water pump clearance. Carefully install the O-Ring (supplied) in the groove on the back side of the adapter plate. Remove the locking screw from the center of the adapter plate and turn the Quick Button® cam button counter-clockwise until it is bottomed-out against the adapter plate. Install the Adapter Plate and Quick Button® Cam Button.Torque these screws to 160 in-lb (13 ft-lb) using your 3/16″ Hex Wrench. Install the ten (10) mounting screws (not supplied). Use a small amount of gasket sealer if desired. Mount the Timing Cover over the aligning pins on the engine block. Be sure to keep the seal straight in the cover. Tap the seal in place until it is flush with the timing cover. Carefully tap the oil seal (not supplied) into the timing cover from the front side. Push the camshaft sprocket firmly against the engine block to remove any endplay. Loosen the oil pan bolts enough so that the new timing cover can be installed without damaging the gasket. Oil leaks may result unless all surfaces are clean. Clean everything! Make sure that the engine mounting surfaces and timing cover components are as clean as possible.Note: The installation procedures which follow assume that the engine has been disassembled and cleaned as it would be for a normal timing cover change.
