2.46L IN-LINE 4 (CRANKSHAFT) 1072.3.4.5.6.7.8.9.Cut the end tabs off of the replacement timing covergasket corresponding to those cut off the original gasket.Coat the front seal end tab recesses generously withRTV sealant (Mopar Gasket-in-a-Tube, or equivalent)and position the seal on the timing case cover.Apply engine oil to the seal-oil pan contact surface.Position the timing cover on the cylinder block.Place timing case cover alignment and seal installertool in the cover crankshaft opening.Install the cover-to-cylinder block bolts and the oilpan-to-cover screws.Tighten the cover-to-cylinder block bolts with 7 Nom(5 ft-lbs) torque and the oil pan-to-cover screws with13 Nom (1 1 ft-lbs) torque.Remove the cover alignment tool and position areplacement oil seal on the tool with the seal lipfacing outward.10. Apply a light film of Perfect Seal, or equivalent, on theoutside diameter of the seal.11. Lightly coat the crankshaft with engine oil.12. Position the timing case cover alignment and sealinstaller tool with seal over the end of the crankshaft(Figure 2-22). Insert draw screw tool (Figure 2-23).Install seal into timing chain cover by gently tappingwith a rubber or plastic mallet.13. Tighten the nut against the tool until the tool contactsthe cover (Figure 2-23).14. Remove the tools and apply a light film of engine oilon the vibration damper hub contact surface of the seal.15. With the key inserted in the keyway on the crankshaft,install the vibration damper, washer and bolt. Lubricateand tighten the bolt with 108 Nom (80 ft-lbs) torque.Note: If the crankshaft turns before the damper bolttightening torque value is attained, the crankshaft canbe prevented from turning by placing two 5/16 x 1-1/2"bolts into the damper pulley holes and wedging a barbetween them. Rotate the bar until it contacts the framemember to prevent the crankshaft from turning.16. Install the damper pulley. Tighten the bolts with 27Nom (20 ft-lbs) torque.17. Install the engine fan and hub assembly.18. Install the fan shroud.19. Install the drive belt(s) and tighten to the specified tension.TIMING CHAINRemovalNote: The timing chain tensioner reduces noise andprolongs timing chain life. In addition, it compensates forslack in a worn or stretched chain and helps to maintain thecorrect valve timing.1. Remove the fan and shroud.2. Remove the drive belt(s).3. Remove the crankshaft vibration damper and pulley.4.5.6.7.8.Remove the timing case cover. Refer to Timing CaseCover Removal, in this section, for the procedure.Remove the crankshaft oil slinger.Rotate the crankshaft until the zero degree (0") timingmark on the crankshaft sprocket is closest to and on thecenterline with the timing mark on the camshaft sprocket.Remove the camshaft sprocket retaining bolt.Remove the sprockets and chain as an assembly.Installation1. Turn the tensioner lever to the unlocked (down)position (Figure 2-25).2.3.4.5.6.7.8.Pull the tensioner block toward the tensioner lever andcompress the spring. Hold the block and turn thetensioner lever to the locked (up) position (Figure 2-25).Install the camshaft sprocket, crankshaft sprocket andtiming chain with the timing marks aligned (Figure 2-26).Note: To verify correct installation of timing chain,turn the crankshaft to position the camshaft sprockettiming mark at approximately the one o'clock position(Figure 2-26). This positions the crankshaft sprockettiming mark where the adjacent tooth meshes with thechain at the three o'clock position. Count the numberof chain pins between the timing marks on bothsprockets. There must be 20 pins.Tighten the camshaft sprocket bolt with 108 Nom(80 ft-lbs) torque.Release the timing chain tensioner lever.Install the crankshaft oil slinger.Install the timing case cover. Refer to Timing CaseCover Installation, in this section, for the procedure.Install the vibration damper on the crankshaft.. ..
