Removal 1. Disconnect negative battery cable. Raise and support vehicle. Drain engine oil. Remove right front wheel and splash shield. Put a block of wood between cradle and engine torque strut at bottom front end of engine. See Fig. 2 . 2. Remove mount from upper front end of engine, allowing engine to rest on wood block. Remove accessory drive belt and tensioner. Remove accessory belt idler. Remove cylinder head cover. 3. Replace silicone isolators on cylinder head cover screws if deteriorated. Remove power steering pump (leave hoses attached). Remove A/C compressor (leave hoses attached). Raise and support vehicle. Drain engine oil. Remove right front wheel and splash shield. 4. Remove support bracket between intake manifold and engine block. Remove front balancer/pulley using a 3-jaw puller. Disconnect exhaust pipe from exhaust manifold. Install Crankshaft Gear Retainer (SA9104E) onto end of crankshaft, with flat side toward crankshaft gear (sprocket). Crankshaft gear retainer holds crankshaft gear in place during removal of front cover. 5. Remove 4 bolts from front end of oil pan. Using RTV Cutter (SA9123E), cut RTV sealant between oil pan and front cover. Spray penetrating oil onto front cover dowel pins. Remove front cover bolts (one bolt is located above accessory drive belt pulley). Pry front cover from engine block. 6. To prevent pistons from hitting valves, turn crankshaft 90 degrees clockwise as viewed from front of engine until timing mark and keyway are aligned with split line of main bearing cap. Remove timing chain tensioner, guides and chain. While using a 7/8″ (21 mm) wrench to keep camshaft(s) from turning, remove camshaft sprocket bolt(s). Remove camshaft sprocket(s). Installation 1. To prevent pistons from hitting valves, ensure timing mark and keyway on crankshaft are aligned with split line of main bearing cap. Install camshaft sprocket(s) with the letters FRT (front) facing away from cylinder head. Use a 7/8″ (21 mm) wrench to keep camshaft(s) from turning. 2. Install and tighten camshaft sprocket bolt(s) to specification. Rotate camshaft(s) until a 3/16″ (4.8 mm) drill bit can be inserted through timing pin hole(s) and into cylinder head. See Fig. 5 or Fig. 6 . 3. Rotate crankshaft counterclockwise as viewed from front of engine until timing marks at crankshaft sprocket are aligned. Install timing chain, aligning Silver-plated chain links with timing mark(s) on camshaft sprocket(s) and bottom tooth (or teeth) of crankshaft sprocket. See Fig. 5 or Fig. 6 . 4. Install fixed chain guide. Slack part of chain should be on tensioner side of cylinder block. Chain should be tight against fixed chain guide. Install pivoting chain guide. Retract tensioner plunger, and pin ratchet

REMOVAL 1.Remove upper intake manifold. 2.Remove cylinder head covers, crankshaft damper, and timing chain cover. CAUTION: When aligning timing marks, always rotate engine by turning the crankshaft. Failure to do so will result in valve and/or piston damage. Fig. 70 3.Align crankshaft sprocket timing mark to mark on oil pump housing (Fig. 70). The mark on oil pump housing is 60° ATDC of #1 cylinder. CAUTION: When the timing chain is removed and the cylinder heads are still installed, DO NOT rotate the camshafts or crankshaft without first locating the proper crankshaft position. Failure to do so will result in valve and/or piston damage Fig. 74 4.Remove primary timing chain tensioner from right cylinder head (Fig. 74). 5.Remove camshaft position sensor from left cylinder head (Fig. 69). 6.Remove chain guide access plug from left cylinder head (Fig. 69). NOTE: When camshaft sprocket bolts are removed, the camshafts will rotate in a clockwise direction. 7.Starting with the right camshaft sprocket, remove the sprocket attaching bolts. Remove camshaft damper and sprocket (Fig. 69). 8.Remove left side camshaft sprocket attaching bolts and remove sprocket (Fig. 69). 9.Remove lower chain guide and tensioner arm (Fig. 69). 10.Remove the primary timing chain. INSTALLATION 1.Inspect all sprockets and chain guides. Replace if worn. Refer to Crankshaft Gear/Sprocket, for removal and installation procedures. 2.If removed, install right and left side short chain guides (Fig. 69). Tighten attaching bolts to 28 Nm (250 in. lbs.) 3.Align crankshaft sprocket timing mark to the mark on oil pump housing (Fig. 71). NOTE: Lubricate timing chain and guides with engine oil before installation. 4.Place left side primary chain sprocket onto the chain so that the timing mark is located in-between the two (plated) timing links (Fig. 71). 5.Lower the primary chain with left side sprocket through the left cylinder head opening

TIMING CHAIN AND SPROCKETS Precaution: Timing Chain Replacement CHAIN GUIDES AND TENSIONER ARMS: Replace these parts if grooving in plastic face is more than 1 mm (0.039 inch) deep. If plastic face is severely grooved or melted, the tensioner lube jet may be clogged. The tensioner should be replaced. REMOVAL 1. Disconnect negative cable from battery. 2. Drain cooling system . 3. Remove right and left cylinder head covers. 4. Remove radiator fan shroud. 5. Rotate engine until timing mark on crankshaft damper aligns with TDC mark on timing chain cover (Fig. 132) (# 1 cylinder exhaust stroke) and the camshaft sprocket “V8″ marks are at the 12 o’clock position (Fig. 133). 6. Remove power steering pump. 7. Remove access plugs (2) from left and right cylinder heads for access to chain guide fasteners (Fig. 134). 8. Remove the oil fill housing to gain access to the right side tensioner arm fastener. 9. Remove crankshaft damper and timing chain cover. 10. Collapse and pin primary chain tensioner (Fig. 135). CAUTION: Plate behind left secondary chain tensioner could fall into oil pan . Therefore, cover pan opening. 11. Remove secondary chain tensioners. 12. Remove camshaft position sensor from right cylinder head (Fig. 136). CAUTION: Care should be taken not to damage camshaft target wheel. Do not hold target wheel while loosening or tightening camshaft sprocket. Do not place the target wheel near a magnetic source of any kind. A damaged or magnetized target wheel could cause a vehicle no start condition. CAUTION: Do not forcefully rotate the camshafts or crankshaft independently of each other. Damaging intake valve to piston contact will occur. Ensure negative battery cable is disconnected to guard against accidental starter engagement. 13. Remove left and right camshaft sprocket bolts.

installation Notes NOTE: Ford does not provide a procedure to align the timing components without the OE tools specified. 1. Compress the tensioner plunger, using an edge of a vise. CAUTION: Timing chain procedures must be followed exactly or damage to valves and pistons will result. Do not compress the ratchet assembly. This will damage the ratchet assembly. 2. Use a small screwdriver or pick to 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. Remove the tensioner from the vise. 7. If the copper links are not visible, mark two links on one end and one link on the other end, and use as timing marks. 8. Loosely install the Camshaft Holding Tools on both camshafts 9. Install the timing chain guides . 10. Rotate the LH camshaft with the Camshaft Positioning Tool until the timing mark is approximately at 12 o’clock. Rotate the RH camshaft with the Camshaft Positioning Tool until the timing mark is approximately at 11 o’clock. Tighten the Camshaft 11. Position the crankshaft with the Crankshaft Holding Tool. CAUTION: Unless otherwise instructed, at no time when the timing chains are removed and the cylinder heads are installed is the crankshaft or camshaft to be rotated. Severe piston and valve damage will occur. Rotate the crankshaft counterclockwise only. Do not rotate past position shown or severe piston and/or valve damage can occur. 12.
