Use the j 41816-2 , j 41558 , bolts and j 8433 to disassemble the Crankshaft sprocket and then take off the Crankshaft sprocket (207) with its key. To install the key position it in the Crankshaft keyway and keep tapping until both ends match up completely. Place the Crankshaft sprocket (207) onto the Crankshaft alignment its key with sprocket keyway while fastening it completely to the Crankshaft flange by applying the j 41478 and j 41665 . Position the sprocket's alignment mark at 12 o'clock before compressing the Timing Chain Tensioner guide and installing the en 46330. Use the Timing Chain Tensioner (232) and bolts (231) to install at 25 n.m (18 lb ft). Verify proper engagement of sprocket teeth while inspecting alignment marks located on both camshaft and Crankshaft sprockets. After mounting the camshaft sprocket (205), Timing Chain (208), and bolt (206), validate the correct timing by confirming both sprocket marks: camshaft at 6 o'clock and Crankshaft at 12 o'clock. Installation of en 46330 is followed by short-term attachment of automatic transmission flex plate or manual transmission Flywheel and bolts.
