Timing Drive Components: Removal

WARNING: This page is about a different car, the 2018 Ford Focus. However, it is still accessible from the selected car via links, so may be relevant.

NOTE: 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.

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: Engines built prior to 12/9/2014 are equipped with diamond washers on both sides of the crankshaft sprocket. Engines built on or after 12/9/2014 have a laser etched crankshaft sprocket and do NOT require diamond washers. If an engine built prior to 12/9/2014 requires crankshaft sprocket replacement, discard the diamond washers and the sprocket and install a new laser etched sprocket (service part). Diamond washers should NEVER be installed with the laser etched sprocket.

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).
