Remove the starter and hold the teeth on the ring gear with a large prybar and get a helper to undo the bolt. Or if you have a impact use that. Remember to put a bit of lok-tite on the threads and torque it to specs when you are done. I am assuming you are chaning a timing belt. Do not hold the engine from turning by the valvetrain, ex. Locking the cams in place and cranking on the crankshaft bolt. Removed starter! remember also to take the battery cables off if you havent already to avoid shorting out the electrical system.

A worn or stretched timing chain will adversely affect valve timing. If the timing chain deflects more than 12.7 mm (1/2 inch) replace it. The correct timing chain has 48 pins. A chain with more than 48 pins will cause excessive slack.INSTALLATIONAssemble the timing chain, crankshaft sprocket and camshaft sprocket with the timing marks alignedApply Mopar Silicone Rubber Adhesive Sealant to the keyway in the crankshaft and insert the key.

There is a special tool ( a puller ) to remove the crankshaft sprocket.There is a special tool ( a puller ) to remove the crankshaft sprocket.
