Valve Tappets: Removal
WARNING: This page is about a different car, the 2003 Ford Focus. 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 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.
- Mark the position of the camshaft lobes on the No. 1 cylinder for assembly reference.
- Loosen the camshaft bearing bolts in the sequence shown, one turn at a time. Repeat until all the tension is released.
- Remove the camshaft bearing caps.
- Remove the camshafts.
- Remove the valve tappets.
- Inspect the valve tappets. For additional information, refer to ENGINE SYSTEM-GENERAL INFORMATION .
CAUTION:
Failure to follow the camshaft loosening procedure can result in camshaft damage.
CAUTION:
If the camshafts and valve tappets are to be reused, mark the location of the valve tappets to make sure they are assembled in their original positions.
NOTE:
The number on the valve tappets only reflects the digits that follow the decimal. For example a tappet with the number 0.650 has the thickness of 3.650 mm.
