Pully install problem

CaliJ1 · 07-24-2003, 10:55 PM

I have a 99 GT and am trying to install some bbk pullys. The only problem I cannot get past is getting the nut off the crank pully. I have tried everything. From manually trying to loosen the nut with a torque wrench to using an impact wrench and an impact gun. It just won't budge. Is it possible the nut has seized up? If so does anyone have any ideas? Do I have a better chance during cooler weather?

Thanks.

Try spraying some WD-40 on it,that might help.

Can you get a torch in there just to heat the nut up, expand the nut a bit.

You mean the "bolt" on the pulley? I only needed my short little 3/8" ratchet to get mine off. If an impact won't get it off (Well a good impact, like an IR

) you're sol.

Don't heat the bolt, it will just expand and make it harded to get out. Try some WD-40 or Liquid wrench. Then try a big impact again, something with 500-700 ft lbs of torque.

get a 4' long bar, like a floor jack handle or something and give it a try!

CaliJ1 · 07-28-2003, 08:14 PM

I tried the wd-40 and some silicon spray and it did not work. I will try the four foot bar and see what happens. If you have any other suggestions please keep them coming. Thanks again.

Did you try removing the bolt while the engine is hot with an IMPACT wrench? If not try it...If you shear the bolt head off, your in for an expensive fix.

Good Luck...

Get yourself the latest and greatest torque monster impact gun from Ingersoll-Rand! If you can get your hands on one

CaliJ1 · 07-29-2003, 06:57 PM

I actually have tried to get the nut off when it was about 85 degrees with an impact gun, but with no success. ANd my biggest fear is breaking the nut. Oh well. I will see what I can do about getting the latest and greatest from Ingersoll-Rand. Thanks for the help.

Cali...

I meant the engine...in regards to having the metal hot so all parts are expanded.

yes, heating it will expand it, but this makes it easier to get out (from my experience.) ive never heard someone say NOT to heat it for the exact reason that you are supposed to heat it. is it a location/specific bolt issue? typically if you get that sucker cherry red and impact it, shes comin loose.

95mustanggt · 07-30-2003, 08:23 PM

My experience (from bushing and bearing installs) is typically to heat the outer race or area and cool the bushing or bearing.

But maybe bolts are different. Although from a metallurgical stand point, the bolt is more likely be unable to reject the heat and therefore expand more than the surrounding material and become stuck. Theoretically speaking of course

ac97gt · 07-31-2003, 12:34 AM

from actual experience the heat allows it to expand and come loose. tell any good mechanic you have a seized bolt and the first thing they will tell you is to get it cherry red. i had a seized bolt on the hardest damn bolt to get to (pass. side) on my stock h pipe that we heated the hell out of and finally banged loose with a chisel. no doubt the heat helped immensely.
