I'm definitely no mechanic, and I'm having trouble replacing the crankshaft sprocket on my 1994 Pontiac Sunbird. I've gotten the front timebelt cover, timebelt, camshaft sprocket, and timebelt tensioner off, but the bolt holding the crankshaft sprocket on does not want to budge. I need to remove the crankshaft sprocket because it needs to be replaced (some damage to the teeth) and I also need to replace the water pump, which is behind the rear timebelt cover.
I've been doing some searching, and it appears that some tools may help, but I'm not sure. A harmonic balancer puller seems like it would help, but given what I was told a harmonic balancer is and what it does, I don't see how that particular tool will help me.
Any help would be greatly appreciated -- I can't afford to take the vehicle to a garage (I was given a quote of over $500 to replace the belts, upper radiator hose, thermostat, and water pump and over $350 just to replace the water pump) and the work has gone pretty smoothly up until this point.
Thanks to all who are willing to help me!
