Installation

SPECIAL TOOLS REQUIRED





INSTALLATION








1. Install timing chain guides (both sides). Install timing chain guide retaining bolts. Tighten to 8-12 Nm (71-106 inch lbs.).

NOTE:
- If engine has jumped time, make sure that all repairs to engine components and/or valve train have been made. Then rotate engine counterclockwise 45 degrees. This will position all pistons below top of deck face. Install cylinder heads.
- Cam Positioning Tool Adapters 303-413 and Cam Positioning Tool 303-380 must be installed on camshaft to prevent camshafts from rotating.

2. If removed, position LH camshaft sprocket spacer and camshaft sprocket on camshaft.
3. Install washer and camshaft sprocket retaining bolt. Do not tighten at this time.
4. If removed, position RH camshaft sprocket spacer and camshaft sprocket on camshaft.
5. Install washer and camshaft sprocket retaining bolt. Do not tighten at this time.








6. If, removed, install LH crankshaft sprocket.

NOTE:
- Crankshaft sprockets are identical. They may only be installed one way. Refer to the illustration for proper crankshaft sprocket installation.
- Make sure tapered part of crankshaft sprocket faces away from cylinder block.

Timing Chain Marks:

7. Install LH timing chain on camshaft sprocket. Make sure copper link of timing chain lines up with timing mark of camshaft sprocket.

NOTE: If copper links of timing chain are not visible, split both timing chains in half and mark the two opposing links as shown.

8. Install LH timing chain on crankshaft sprocket. Make sure copper link of timing chain lines up with timing mark of crankshaft sprocket.
9. If removed, install RH crankshaft sprocket.

Fig. 26 Crankshaft Sprocket Position:

NOTE: Make sure tapered part of crankshaft sprocket faces toward cylinder block.

10. Install RH timing chain on camshaft sprocket. Make sure copper link of timing chain lines up with timing mark of camshaft sprocket.

Fig. 25 Crankshaft To Camshaft Timing:

11. Install RH timing chain on crankshaft sprocket. Make sure copper link of timing chain lines up with timing mark of crankshaft sprocket.
12. Install RH and LH timing chain tensioner and secure with two bolts on each. Tighten bolts to 20-30 Nm (15-22 ft. lbs.).





13. Install Crankshaft Holding Tool 303-448 over crankshaft and engine front cover alignment dowel to position crankshaft.








14. Lubricate timing chain tensioner arm contact surfaces with clean Super Premium SAE 5W30 Motor Oil XO-5W30-QSP meeting Ford specification WSS-M2C153-G land install RH and LH timing chain tensioner arms on their dowels.
15. With a suitable C-clamp around the timing chain tensioner arm and timing chain guide, remove all slack from timing chain while using caution not to bend the timing chain guide.





16. Remove lock pins from timing chain tensioners and make sure all timing marks are aligned.
17. Using Cam Positioning Tool Adapters 303-413 and Cam Positioning Tool 303-380 to align camshaft, tighten camshaft sprocket bolt to 110-130 Nm (82-95 ft. lbs.).
18. Install Tool-4201-C Dial Indicator with Bracketry or equivalent in cylinder 1 spark plug hole. Check that camshaft is at maximum lift for the intake valve at 114 degrees after top dead center (TDC).

NOTE: If not at maximum lift, loosen camshaft sprocket bolt and repeat Steps 12- 15.


19. Remove Cam Positioning Tool Adapters 303-413, Cam Positioning Tool 303-380 and Crankshaft Positioning Tool 303-445.
20. Install engine front cover and valve covers.
21. Start engine and check for leaks and proper operation.
