I'm doing underdrive pulleys on my 04' 4.6 GT and the crank pulley isn't coming off, even with an impact. Does anyone know if it is reverse threaded? Thanks
I just don't remember because my brother and I were doing it togther, plus I was drinking. I think it is but I don't know for sure. Sorry man. I would ask him but he is at work right now.silver04stang said:well if you took it off...wouldn't you know if you took it off in reverse?
Cool, thanks for clearly that upblackink00 said:no its not reverse thread. when i did mine i tried for liek half an hour then i got a huge cheater bar hugged my legs around the tire cussed alot and pull like no other. there on there super tight but it is regular thread and it can be done.
A few questions, I am about to do the install on a 98 GT:We finished it. It was kind of wierd actually. There was a washer on it and it kept turning too. I don't know exactly cause my friend was under the car when we were taking it off, but once we held the washer, it came off rather easily with some PBblaster. Everything else went smoothly. Thanks for your help guys.
A few questions, I am about to do the install on a 98 GT:
1. What brand of underdrive pulleys did you install?
2. You used a harmonic balance puller tool, right?
3. Any advice?
Can you expand on this large screwdriver being wedged? Pics? Drawing? I have an auto so I need to do something to hold that crank pulley still.Get some PBblaster and spray it down. A cheater bar on the wrench helps. I had to wedge a large screwdriver against the block and pulley to keep it from turning.
I bought the Steeda Underdrive Pulleys, so it came with a new bolt, but it says NOT to use it, that it's for alignment only. Also, it's not the piggyback type. I also have a harmonic puller, so that's no problem.The puller is a must...
Replace the crank bolt with a new one if you kit doesn't have one. Also get pullies that replace the crank pulley...not piggyback type.

I would also like to know how you used the screwdriver as a wedge. I tried for an hour to get the alternator pulley off, as well as the crank pulley. I ended up using PB blaster on both, and that didn't help ONE bit. It only made things worse...I have a really squeaky belt now
ANY help/advice would be appreciated...thanks![]()
I can tell you though, that you can still use the OEM pulley (smaller diameter = spins faster = charges more) with this kit, and the stock belt. I kept my smaller pulley on to eliminate potential charging problems.
I returned the pulleys. If I decide to buy them again, I'll save $32 by buying them elsewhere.
