NOTE:
Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed in this procedure. The crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction. For that reason, the crankshaft sprocket is also unfastened if the pulley bolt is loosened. Before any repair requiring loosening or removal of the crankshaft pulley bolt, the crankshaft and camshafts must be locked in place by the special service tools, otherwise severe engine damage can occur.
NOTE:
During engine repair procedures, cleanliness is extremely important. All parts must be thoroughly cleaned and any foreign material, including any material created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan, can cause engine failure.
NOTE:
If it is necessary to install a new timing chain tensioner, a cast iron tensioner is to be replaced with an aluminum tensioner (6K254). The existing bolts must be discarded and replaced with new bolts (6K282).
NOTE:
For additional information, refer to the exploded view under the Assembly procedure.

Diamond washers should NEVER be installed with the laser etched sprocket.
If equipped, remove the diamond washer.
