Valve Tappets: Removal

WARNING: This page is about a different car, the 2004 Ford Ranger. However, it is still accessible from the selected car via links, so may be relevant.

CAUTION: The crankshaft, the crankshaft sprocket and the pulley are fitted together by friction, with diamond washers between the flange faces on each part. For that reason, the crankshaft sprocket is also unfastened if you loosen the pulley. Therefore the engine must be retimed each time the damper is removed. Otherwise severe damage can occur.

NOTE: Valve tappets are select fit and the valve clearance must be checked before removing the tappets. For additional information, refer to VALVE CLEARANCE CHECK . If the valve clearance has already been checked, proceed with removal.

Remove the timing chain. For additional information, refer to TIMING DRIVE COMPONENTS .
Remove the special tool.
