Okay.. so my car is in the process of having my vortech installed. the shop calls me today and explains how they can not get my UR crank pulley off. They said they have tried almost everything to get it off, and they fear to try anymore because they don't want to damage the crank itself. My first questions is, has anyone heard of this happening before? Second, does anyone know of any tricks to get it off? And third, how bad is it to run the UR crank pulley with the SC? I've heard that it can be bad in the long run, but the shop is telling me that it's not bad for the car, but it will just cause the car to make less boost. Our theory was to run a smaller boost pulley on the SC to compensate for the lower amount of boost due to the UR pulley. ANY ADVISE/HELP WOULD BE APPRECIATED.

 

You wanna get that off, a 9 psi pulley will only generate 6psi with that on

 

Any ideas or recommendations to get that f*cker off? I could careless about damaging the pulley itself, but I really don't want to bother the crank.

 

Did a shop put it on ? Sounds like they didnt use any ...Never Sieze.... on it .

 

yeah...this is another Street Image install gone bad...he had it installed there and im sure they didn't use that stuff. with an aluminum pulley it is easy to lock it in there like that...Randy didn't even have any suggestions as to how it could be fixed

 

using a long pipe on the end of the ratchet will give you a lot more leverage, like the handle on your jack

 

Your shop needs something like this

The jaws clamp to the outside pulley grooves and the center threaded driver pulls it off by pushing on the end of the crank. No pressure on the crank or bearings since it is exerting all the force at the pulley, not relative to the block.

 

Also, have them spray on some penetrating oil and have it soak overnight. Should pull right off in the morning.

 

If it's really stuck in there you can just get a smaller pulley. Vortech makes pulleys for a lot higher boost, just get one size smaller pulley.

 

use a hand grinder with a cutting wheel to cutt the edge of the bolt. I will take some of the pressure off the bolt. I did it to get my crank pulley off a couple of weeks ago

 

I dunno guys... looks like im SOL - ill probably just end of keeping until the install is complete and then go from shop to shop until it someone can get it off

 

Penetrant and gear puller as suggested above. Very little risk, and works about 100% of the time. Done it at least a dozen times. Good luck. If your shop does not have a gear puller, I hope they're better with superchargers. I would run in the other direction.

 

The is a good shop.. I'm sure most of you have heard of GT Motorsports. Talked to Sam today, and they are going to figure something out. I'll find out on Monday when I swing by to drop off a few more things.

 

damn, I have ur crank pulleys and accessary pulleys also so I hope I dont run into this problem when I take them out.

Is it bad to run it with the UR crank and other pulleys with the vortech under than making less boost? Also, are u sure it will only make 6psi with a 3.12 pulley? So what will running a 2.87 pulley make?

 

Yes, it will only make around 6 psi with the UR pulley on. Not sure with the 2.75, don't know anyone that has tried it.

 

I had that problem when I repleced the OEM pullies with CNR pullies. what I did, I put on an extension on the ratchet ( with the car on the floor, not jackedup) and the ratchet at about 5.00 oclok resting on the floor. Then I bumped the starter (very lightly) and that was it!!!. Piece of cake!!

 

your ****ed... you arent going to get it off...i went through this problem a year and a half ago and nobody believed me... i lost an engine because of pullies.... and you are number 3 in the last week with pully problems.... it will be alot more of a problem as people start trying to remove them

 

I've also heard it can cause added wear on your crank over time, causing more problems than normal.

 

so ppl with turbo dont cause more wear on the crank over time either?

 

What are you talking about?

I'm saying using the UR crank pulley with the SC will cause more wear than having the SC without the UR crank pulley (i.e. OEM crank pulley)

Who said anything about turbo's and not causing wear?
