Timing Chain Guide: Service and Repair

NOTE: Ford does not provide a TDC (Top Dead Center) mark or determination procedure for this engine in this vehicle.
ALLDATA users have reported success using aftermarket tools to determine TDC on this engine.

REMOVAL
1. Remove engine assembly.
2. Remove engine front cover.
3. Remove camshaft sprocket bolt from end of the camshaft.
4. Remove camshaft position sensor drive gear.
5. Remove camshaft sprocket, crankshaft sprocket and timing chain simultaneously.

NOTE: If crankshaft sprocket is difficult to remove, loosen crankshaft sprocket using a pair of large screwdrivers positioned on both sides of the crankshaft sprocket.

6. Remove timing chain vibration damper (three bolts) from front of cylinder block. (This requires first pulling back on ratcheting mechanism, then installing pin through hole in bracket to relieve tension.)

INSTALLATION
1. Rotate crankshaft as necessary to position No. 1 piston at TDC and crankshaft keyway at the 12 o'clock position.
2. Install timing chain tensioner using three mounting bolts and tighten bolts to 8-14 Nm (71-124 inch lbs.). Make sure ratcheting mechanism is in retracted position with pin in place. Do not remove pin until timing chain has been assembled.

NOTE: Balance shaft drive gear should be in place prior to Step 3.

4. Remove pin from timing chain tensioner to load timing chain vibration damper arm against timing chain.

Fig. 9 Timing Mark Alignment:

Make sure timing marks on crankshaft sprocket and camshaft sprocket are positioned across from each other as shown in illustration. The engine balance shaft driven gear and engine balance shaft drive gear must be positioned as illustrated.

5. Install camshaft position sensor drive gear.
6. Install camshaft sprocket bolt at end of camshaft and tighten to 40-50 Nm (29-37 ft. lbs.).
7. Install engine front cover.
