Timing Components: Service and Repair

Special Tools:

Removal

CAUTION: Since the engine is not free-wheeling, if the crankshaft or the camshafts are moved in any manner during removal and installation the crankshaft and camshaft must be resynchronized. These steps are located in Engine; Service and Repair; Assembly, Steps 36-48.





1. Remove the engine front cover.





2. Remove the crankshaft sensor ring from the crankshaft.





3. Remove the six bolts and remove the balance shaft bearing caps.





4. Remove the balance shaft.





5. CAUTION: Unless otherwise instructed, at no time when the timing chain/belts are removed and the cylinder heads are installed may the crankshaft or camshaft be rotated. Severe piston and valve damage will occur.

Use the Crankshaft Holding Tool to position the crankshaft as shown.





6. Install and carefully tighten the Camshaft Holding Tools on the camshafts.





7. Remove the timing chain tensioning system from both timing chains.
1. Remove the bolts.
2. Remove the timing chain tensioners.
3. Remove the timing chain tensioner arms.





8. Remove the LH and RH timing chain/belts and the crankshaft sprockets.
1. Remove the RH timing chain/belt from the camshaft sprocket.
2. Remove the RH timing chain/belt and outer crankshaft sprocket from the crankshaft.
3. Repeat for the LH timing chain/belt and crankshaft sprocket.





9. Remove the timing timing chain guides.
^ Remove the bolts.
^ Remove the timing chain guides.

Installation

CAUTION: Timing chain procedures must be followed exactly or damage to valves and pistons will result.





1. CAUTION: Do not compress the rachet assembly. This will damage the rachet assembly.

Compress the tensioner plunger, using an edge of a vise.





2. Using a small screwdriver or pick, push back and hold the ratchet mechanism.





3. While holding the ratchet mechanism, push the ratchet arm back into the tensioner housing.





4. Install a paper clip into the hole in the tensioner housing to hold the ratchet assembly and plunger in during installation.





5. If copper links are not visible, mark two links on one end and one link on the other end, and use as timing marks.





6. Install the timing chain guides.





7. Position the crankshaft with the Crankshaft Holding Tool, and remove the tool.





8. Install the inner crankshaft sprocket with the long hub facing outward.





9. Install the inner timing chain/belt on the crankshaft sprocket with the timing marks aligned.





10. NOTE: Be sure the upper half of the timing chain/belt is below the tensioner guide dowel. If necessary, use the Camshaft Positioning Tool to adjust.

Install the timing chain/belt on the camshaft sprocket with the two chain links and timing marks aligned.





11. CAUTION: The camshaft sprocket can jump time if the Camshaft Holding Tool is not secured.

NOTE: Be sure the chain link and crankshaft sprocket timing marks are aligned.

NOTE: The lower half of the timing chain/belt must be positioned above the dowel.

Install the outer crankshaft sprocket and timing chain/belt with the long hub of the crankshaft sprocket facing inward.
12. Position the timing chain/belt on the camshaft sprocket. Make sure the two copper-colored links align with the camshaft sprocket timing mark.





13. Check for proper alignment of all timing marks.





14. Position the LH and RH timing chain tensioner arms on the dowel pins. Position the timing chain tensioners and install the bolts.





15. Remove the retaining pins from the RH and LH timing chain tensioners





16. Remove the Camshaft Holding Tools from the camshafts.





17. Install the crankshaft sensor ring on the crankshaft.
18. Lubricate the balance shaft journals with engine oil.
^ Use Super Premium SAE 5W30 Motor Oil XO-5W30-QSP or equivalent meeting Ford specification WSS-M2C153-G





19. Position the balance shaft on the journals.





20. Align the balance shaft timing marks as shown.





21. Install the bearing caps, the bolts and tighten the bolts in the sequence shown.





22. NOTE: The timing chain/belt is removed for clarity.

NOTE: If not secured within 4 minutes, sealant must be removed and the sealing area cleaned with solvent. Allow to dry until there is no sign of wetness, or 4 minutes, whichever is longer. Failure to follow this procedure can cause future oil leakage.

Apply a bead of silicone along the cylinder head-to-block surface and the oil pan-to-block surface.
^ Use Silicone Gasket and Sealant F6AZ-19562-AA or equivalent meeting Ford specification WSE-M4G323-A6.

23. Install engine front cover.
