Removal

NOTICE: Do not loosen or remove the crankshaft pulley bolt without first installing the special tools as instructed inthis procedure. The crankshaft pulley and the crankshaft timing sprocket are not keyed to the crankshaft. Thecrankshaft, the crankshaft sprocket and the pulley are fitted together by friction, using diamond washers between theflange 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 belocked in place by the special service tools, otherwise severe engine damage can occur.

NOTICE: During engine repair procedures, cleanliness is extremely important. Any foreign material, including anymaterial created while cleaning gasket surfaces, that enters the oil passages, coolant passages or the oil pan cancause engine failure.

NOTE: If it is necessary to install a new timing chain tensioner, a cast iron tensioner is to be replaced with an aluminumtensioner (6K254). The existing bolts must be discarded and replaced with new bolts (6K282).

1. With the vehicle in NEUTRAL, position it on a hoist.Refer to: Jacking and Lifting - Overview (100-02 Jacking and Lifting, Description and Operation).

2. Remove the following items:1. Fuel injection pump and tappet.

Refer to: Fuel Injection Pump (303-04 Fuel Charging and Controls - 2.0L EcoBoost (184kW/250PS) - MI4).

2. RH fender splash shield.Refer to: Fender Splash Shield (501-02 Front End Body Panels) .

3. NOTICE: The fuel injection cam lobe must be positioned at zero lift before removing the fuel injection pumphousing.

Rotate the crankshaft pulley clockwise slowly until fuel injection cam lobe must be positioned at zero lift.

6. Remove the engine front cover.Refer to: Engine Front Cover (303-01B Engine - 2.0L EcoBoost (184kW/250PS) - MI4, Removal and Installation).

7. NOTICE: The Camshaft Alignment Tool is for camshaft alignment only. Do not rely on the CamshaftAlignment Tool to prevent camshaft rotation. Damage to the tool or the camshaft can occur.

Install Special Service Tool: 303-1565 Alignment Tool, Camshaft.

8. NOTICE: Use an open-ended wrench to prevent the component from turning.

Using an open-ended wrench, loosen the exhaust VCT unit bolt.

Using an open-ended wrench, loosen the intake VCT unit bolt.

10. NOTE: If equipped with cast iron timing chain tensioner.

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 thetiming chain arm toward the tensioner.

3. Insert a holding pin into the hole to retain the tensioner.

11. NOTE: If it is necessary to install a new timing chain tensioner, a cast iron tensioner is to be replaced with analuminum tensioner (6K254). The existing bolts must be discarded and replaced with new bolts (6K282).

NOTE: If equipped with cast iron timing chain tensioner.

Remove the bolts and the timing chain tensioner.





12. NOTE: If equipped with aluminum timing chain tensioner.

Remove the bolts and the timing chain tensioner.

13. Remove the timing chain and the timing chain tensioner arm.

Remove the bolts and the timing chain guide.





Installation

1. Install the timing chain guide and the bolts.Torque: 89 lb.in (10 Nm)

Install the timing chain and the timing chain tensioner arm.





NOTE: If equipped with aluminum timing chain tensioner.

NOTE: If the timing chain tensioner plunger is not pinned in the compressed position, follow the next step.

2. Reset the timing chain tensioner. 1. Position the timing chain tensioner in a soft-jawed vise.

2. Spread the ends of the ratchet wire clip apart.

3. Using the soft-jawed vise, compress the plunger to the reset position.

4. Install a locking pin in the 2 holes of the timing chain tensioner body to hold the plunger in place.




3. NOTE: If equipped with aluminum timing chain tensioner.

NOTE: Do not remove the locking pin until the tensioner bolts are tightened.

1. Install the timing chain tensioner and the bolts.Torque: 89 lb.in (10 Nm)
