Procedure

1. Using a small screwdriver or pick, push back and hold the ratchet mechanism.
2. CAUTION: Timing chain procedures must be followed exactly or damage to valves and pistons (6108) will result. If removed, install the left and right camshaft sprockets (6256).
3. CAUTION: Do not compress the ratchet assembly. This will damage the ratchet assembly. Compress the tensioner plunger, using an edge of a vise. ! ! 55-75 Nm (41-55 lb/ft) 02-110 WSG-1068 ENGINE
4. Loosen the Camshaft Holding Tools on both camshafts (6250).
5. If the copper links are not visible, mark two links on one end and one link on the other end to use as timing marks.
6. Install a paper clip into the hole in the tensioner housing to hold the ratchet assembly and plunger in during installation. 02-111 WSG-1068 ENGINE
7. Install the timing chain guides (6K297). 02-112 WSG-1068 ENGINE
8. Rotate the LH camshaft sprocket until the timing mark is approximately at 12 o’clock. Rotate the RH camshaft until the timing mark is approximately at 11 o’clock. Tighten the Camshaft Holding Tools to maintain camshaft pre-positioning.
9. CAUTION: Unless otherwise instructed, at no time when the timing chains (6268) are removed and the cylinder heads are installed is the crankshaft or camshaft to be rotated. Severe piston and valve damage will occur. CAUTION: Rotate the crankshaft counterclockwise only. Do not rotate past the position shown or severe piston or valve damage can occur. Position the crankshaft with the Crankshaft Holding Tool.
10. Remove the Crankshaft Holding Tool. ! ! 02-113 WSG-1068 ENGINE
11. Position the inner crankshaft sprocket (6306) with the long hub facing outward.
12. Install the LH timing chain/belt onto the crankshaft sprocket, aligning the one copper link on the timing chain with the slot on the crankshaft sprocket.
13. NOTE: Make sure the upper half of the timing chain is below the tensioner guide dowel. If necessary, use the Camshaft Holding Tool to adjust. NOTE: If necessary, adjust the camshaft sprocket slightly to obtain timing mark alignment. Position the timing chain on the camshaft sprocket with the two copper chain links and the camshaft sprocket timing mark aligned. 02-114 WSG-1068 ENGINE
14. CAUTION: The camshaft sprocket can jump time if the Camshaft Holding Tool is not secured. NOTE: Be sure the copper chain link and the crankshaft sprocket timing mark are aligned. NOTE: The lower half of the timing chain must be positioned above the dowel. Position the outer camshaft sprocket and the RH timing chain with the long hub of the camshaft sprocket facing inward.
15. NOTE: If necessary, adjust the camshaft sprocket slightly to obtain timing mark alignment. Position the RH timing chain on the camshaft sprocket. Make sure the two copper-colored links align with the camshaft sprocket timing mark. ! 02-115 WSG-1068 ENGINE
16. As a post-check, verify timing mark alignment.
17. Position the LH and RH timing chain tensioner arm (6L253) on the dowel pins. Position the timing chain tensioners (6L266), and install the bolts.
18. Remove both the RH and LH retaining pins from the timing chain tensioner assembly. • 02-116 WSG-1068 ENGINE
19. Remove the Camshaft Holding Tools from the camshafts.
20. 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.
21. Position the balance shaft on the journals.
22. Align the balance shaft timing marks as shown. 02-117 WSG-1068 ENGINE
23. Position the crankshaft sensor ring.
24. 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.
25. Install the bearing caps and the bolts. Tighten the bolts in the sequence shown. 02-118 WSG-1068 ENGINE
26. Install a new engine front cover gasket (6020) onto the engine front cover (6019), then position the engine front cover on the front cover to cylinder block dowel (6C002).
27. CAUTION: Mating parts must make contact to each other within 4 minutes and connecting bolts must be torqued within 15 minutes after applying sealant. Failure to follow this procedure can cause future oil leakage. • Use silicone gasket and sealant F6AZ-19562-AA or equivalent meeting Ford specification WSE- M4G323-A6. NOTE: Sealant must be removed and area cleaned with solvent if above instructions are not followed. • Use metal surface cleaner F4AZ-19A536-RA or equivalent meeting Ford specification WSE- M5B292-A. NOTE: The RH timing chain is removed for clarity. • Apply a bead of silicone along the cylinder head- to-block surface and the oil pan-to-cylinder block surface as specified. ! 02-119 WSG-1068 ENGINE Part Item Number Description 1 N806177 Bolt, Hex Flange Head Pilot, M8 x 1.25 x 53 2 N806177 Bolt, Hex Flange Head Pilot, M8 x 1.25 x 53 3 N806177 Bolt, Hex Flange Head Pilot, M8 x 1.25 x 53 4 N806177 Bolt, Hex Flange Head Pilot, M8 x 1.25 x 53 5 N806177 Bolt, Hex Flange Head Pilot, M8 x 1.25 x 53 6 N808529 Stud, Hex-Head Pilot, M10 x 1.5 x 1.5 x 103.1 7 N808529 Stud, Hex-Head Pilot, M10 x 1.5 x 1.5 x 103.1 8 N808142 Screw and Washer, Hex Pilot, M10 x 1.5 x 57.5
