crankshaft timing gear problem
here is the story, I'll try to keep it short. Timing mark was jumping around culprit was a loose timing chain. The crank gear would not come off. Had to get a gear puller to remove. When I got home with the new chain it was the same ammount of slack as old one. The timing gear will slide until about a half in to block then stops. You can feel where the crank has a little bit bigger diameter than the end. I have nver seen this before, but i was always a mopar guy. Is this typical for a 350? Does this gear need to be pressed on? Any suggestions would be great.

Put the crank gear in the oven at 350* for about 30 minutes. Wear gloves and slip it on the crank, follwed with a pipe that fits over the crank and a couple of whacks with a hammer to seat it. Works everytime and is not so hot it messes with the gear. Make sure you get it oriented correctly- the rear has a chamfer and the timing mark is on the front.
