Timing Chain Tensioner: Service and Repair
Timing Drive Components
Removal
NOTICE: 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, using diamond washers between the flange faces on each part. 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.
NOTICE: During engine repair procedures, cleanliness is extremely important. 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.
