I need to replace the timing belt on my 1987 Chevy Spectrum.. I have everything out of the way, but i just cant get the bolt out that holds on the harmonic balancer/crankshaft pully dampener!!
I've used my impact wrench on it, no luck at all.. even had my friend hold it while i went for the breaker bar..
Anyone hae an idea, or maybe a secret on what to do? My chilton manual doesn't describe anything.. just: remove it with a puller.. yeah i cant remove it with my puller until i get that bolt out!

ive tried all the wd-40, jb-80, CRC Super Synthetic Silicone.. I dont know what to do ... i'll try to round up a 1000 ft/lbs impact from one of my friends and see if that breaks it loose

Try hammering with the impact, be sure to use impact socket, in one direction for about15 sec, then quickly reverse and do the same. Keep this up for at least 6 cycles. This will create some heat and work the bolt loose. Has worked often for me. All that lubricant won't help cause no way to get to threads.

Try setting your impact wrench to a higher tork if possible and spray the bolt with wd 40 and let it set a few minutes before trying again..

make sure you have a good air compreser and a good impact, them cheap ones aint worth a dam, thats all i can think of, good luck.
