How to replace Timing Chain Cover on 2003 Ford Focus?
Removal & Installation

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 you loosen the pulley. Therefore the engine must be retimed each time the damper is removed. Otherwise severe engine damage can occur.
Before servicing the vehicle, refer to the Precautions section.
Disconnect battery negative cable from battery and properly isolate to prevent accidental reconnection.
Remove or disconnect the following:
If the crankshaft position (CKP) sensor is damaged during engine front cover removal a new CKP sensor must be installed.
