IPSCO Pulley Bracket install

[Racngrn]

Hello all. I installed the IPSCO billet P/S pulley and bracket last eve on my 98 GTS. Elected to install leaving the pump in the car to avoid cracking open fittings. Wasn't too bad, other than the lousy access and fitting under the front of the hood for a couple hours. As you all know, the pulley mounting hub must be spread using a screw driver wedged in ( rather far actually) to allow the hub to slide onto the shaft. Followed instructions very carefully and provided for the recommended clearance to the pump body using feeler gauge. It all went together well and appears to work just fine. My stock pulley looks virtually new, but read enough posts to know it was a failure waiting to happen. I perceive what might be a very tiny amount of pulley wobble ( car has 13k miles) , but given the cam and motor shake at idle, it's hard to tell if it is wobble or my imagination. Placed a screw drive against the pull at idle and up to 3k rpm, rides smooth. It seems as though it is rather unlikely that the hub can set itself onto the shaft in any way other than squared up, but I realize that may be an incorrect assumption. Drove the car to work today ( 25 miles and checked everything when I got there. No belt wear, glazing, etc.. Before I close the book on this project, just thought I would ask the experts if there's anything I should check to confirm perfect alignment. I suspect it would have been overall easier on the bench ( as recommended by many) , but this actually went pretty well. Appreciate your thoughts.

Appreciate your thoughts.

Don't be afraid to take hoses off. Matter of fact on your 22 or 23 year old car you should have replaced them both.

Would be nice to hear from the Ipsco guy directly. I think his name is Mark.

Thanks guys. Good point on hoses. I Would definitely pull it next time and that would be a good opportunity to update.

While the Pulley hub will sit square on the pump shaft, the design of the clamping the pulley to the pump shaft uses two tapers, one on the hub (male), and one in the pulley (female) and are critical. That why the instruction ask you to tighten the three screws down an 1/8 of a turn each going around in a circle pattern until the hub and pulley fully seat together. Because of the taper clamping design, if you tighten one screw down more than the others that will cause the tapered hub to crock in the pulley bore tapper and you will not be able to pull is straight with the other two screws, which in-turn will cause the pulley to not run true. So if you see the pulley not running true its due to the hub not seating square and tight to the back of the pulley, and you will need to take the pulley back off the hub and reinstall the two together again. Once the pulley is installed in the car and the belt is on make one more round of tightening the three screws using the belt to hold the pulley from turning.

Did mine on the bench.

I know this don't answer your question but I thought it might interest somebody. I got a brand new still in package Ipsco pulley with hardware and instructions for 1992 - 2002 vipers if anybody needs one. They list at $145.00. I'd take 100 bucks for it.

I also took the pump off and did on bench. 3 bolts and 2 hoses, 20 minutes it was completely off... my OE pulley was a handful to get off. I used the autozone removal tool. maybe there is a better one out there. but it was ON there.

Dave right on, on the hoses. I've had an upper blow apart on me. NOT a fun repair roadside, when car is hot and covered in coolant. LOL

Ditto on removing and bench installing.. Some get lucky getting the pulley off while the pump is in the car. BUT, in my opinion you have one shot (make it count) to get it off. If you fail after the first or so attempt, you may have to take drastic measures to get the pulley off and the pump will need to come off in the end.

Take your time and follow the instructions to a T.

cool, i will pm you

cool, i will pm you

Gavm360, I sent you a pm with my cell number. Give me a call or shoot a text. Thanks.

Thanks for the advice all. I elected to remove the pulley and re-install using greater care in the tightening process. I found a small amount of material ( perhaps dried Loctite) in between the pulley and the hub. Perhaps enough to create a space and wobble. Or, my original tightening sequence contributed to a less than perfect fit. In any case, its back together and rotates perfectly. Glad I took the extra time to R&R. Thanks for the help on this. Does anyone know if the PS hoses are still available from Dodge?

[M5toViper]

One of these comes in handy for the three bolts.

[Racngrn]

You are most certainly correct. Ratcheting box end is a game changer one this, and most box end needs!
