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. 2. 3. 4. Disconnect negative cable from battery. Drain cooling system. Remove right and left cylinder head covers. 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.Related Entry : 09 dodge ram 1500 ac system diagram, 2002 dodge ram 1500 evap core replace diagram, cost to replace a timming chain in a 2004 dodge ram 1500, 2002 dodge ram 5 9 coolant diagram, timing marks 2004 dodge 4 7 litre diagram, how to replace timing chain on 2004 dodge 3 7 engine, how to cheak timing 5 7 hemi, how to cheak timing 2004 5 7 hemi, how to replace timing cover on 2002 dodge ram 4 7 engine, image of time belt for 2004 ram 1500,
