Timing Drive Components: Removal

WARNING: This page is about a different car, the 2010 Mercury Mariner and 2010 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.

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, 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 or severe engine damage can occur.

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.

With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to JACKING & LIFTING -- ESCAPE, ESCAPE HYBRID, MARINER & MARINER HYBRID .
Remove the engine front cover. For additional information, refer to ENGINE FRONT COVER .
Compress the timing chain tensioner in the following sequence.
1. Using a small pick, release and hold the ratchet mechanism.
2. While holding the ratchet mechanism in the released position, compress the tensioner by pushing the timing chain arm toward the tensioner.
3. Insert a paper clip into the hole to retain the tensioner.
