Lincoln Corsair: Engine - 2.0L EcoBoost (177kW/240PS) – MI4 / Removal and Installation - Timing Chain Tensioner
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. 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.
