Engine Crank Shaft Questions and Answers
Question: 1999 Dodge Neon mileage: 60,000. I am trying to remove the
crankshaft dampener pulley in order to remove the head to replace the cylinder head
gasket. I removed the center bolt and tried to pull the dampener with a 3-jaw puller.
It won't budge! I tightened the puller bolt so tight that it started
to bend. With the puller still applying pressure, I tried rapping on the hub
of the dampener using a hammer and a piece of brass round bar and I even tried heating
the hub with a torch (I didn't dare use too much heat, though, for fear of getting
the crankshaft too hot and damaging the front oil seal or igniting the residual
oil on the front of the engine). Is it normal for the dampener to come off
this hard or am I doing something wrong? Any help or insight would be GREATLY
appreciated!
Answer: Assuming that you removed the washer that is behind
the crankshaft bolt, you need to get a special puller for crankshaft pulleys.
If your three-jaw puller is the type used for gears, it will not be strong enough
to remove the pulley.
Question: 2002 Chevrolet Silverado 40,000 miles. Is there
anyway to remove the crankshaft without removing the engine or the transmission
first? I have everything torn apart and I was planning on dropping it out with the
flywheel attached, but I seem to be catching on the torque converter (automatic
transmission). I am guessing that the crank protrudes slightly into the center of
the torque converter, but I didn't think so. I had the transmission out 4 months
ago and I am not looking forward to pulling it out again to get my crankshaft turned.
Answer: Yes, it is possible to get the crankshaft out without
pulling the transmission. Remove the two lower transmission bell housing bolts and
install two longer bolts (approximately 4" long) remove the remaining bolts. Remove
the bolt that holds the cross member to the frame and slide the transmission back
approximately one inch.
