COFFMAN Posted July 17, 2014 Share Posted July 17, 2014 Hi all, I have a issue finding a 98-02 LS1 Camaro P/S pump. Which is I cannot find one, no Aussie GM vehicle used this pump. This is the pump I need for my LS1 conversion. The pump mounts in a different orientation to most GM pump, It has a on-board reservoir with the inlet to the pump being on the top. This pump used with the ICI Billet bracket that I have will take the pump out to Truck belt spacing. The original XJ pump looks to be identical, but when rotated to suit the bracket the reservoir ( filler cap ) is on the side. And will be Approx. 6mm out of alignment ( extra ). I say this because I was going to get the Camaro reservoir to mount to the XJ pump. But with belt spacing being out either the pulley offset is different between XJ & Camaro. The pump body's are different depths. Or the ICI billet bracket needs some machining. So to cover all bases I think it would be best to buy a Complete 98-02 P/S pump But cannot find anyone that sells a complete unit. Trying to eliminate the old wrong parts on the door step scenario if ordering parts separate. Can anyone give me a lead to a supplier of a Complete P/S pump.

COFFMAN Posted July 17, 2014 Author Share Posted July 17, 2014 Thanks dudes, :thumbsup: Rock auto was the one place I didn't try. Order placed Pump with reservoir.. no pulley. Doesn't look like they stock a pulley. Hopefully the XJ one will fit If I don't break it looks to be plastic. I had better update my build thread over the next couple of days..

88ComancheMitch Posted July 17, 2014 Share Posted July 17, 2014 Plastic pulley on jeep started in like 97 or 98. They're poop in my opinion. I swapped the one on my 5.9 to a metal one Link to comment Share on other sites More sharing options...

COFFMAN Posted July 17, 2014 Author Share Posted July 17, 2014 Received notification that it has been shipped. The best I've done is 4 day from the US to outback Tasmania, not to bad at all. As I'm trying to cover all bases with this pump, and the more I think about it. Should be able to swap reservoir from new pump to XJ for initial set up start up.

dankicksass Posted July 18, 2014 Share Posted July 18, 2014 Dorman has OEM type pulleys. #300130. The stock XJ 4.0 pulley is an under drive on GM pumps, if you want to use that. Dorman pulleys are Chinese. Link to comment Share on other sites More sharing options...
COFFMAN Posted July 18, 2014 Author Share Posted July 18, 2014 OK..... so under drive ??? the belt will run under the pulley...? My belt will run over the top of the pulley..... Getting this belt drive assembly right has been one hell of a experience. Do you know if the pulley offset is the same between XJ & Camaro. Thanks........................

I think he's referring the the size of the pulley as it relates to the speed that it drives the pulley/pump........larger the pulley the slower the pump will run.

I know the XJ ps pulley is common for a cheap under drive on LS motors. Last pulley I bought was a stock Chevy after my old ps pump shaft sheared off. New pulley cost me $11. I didn't want to deal with an under drive, I had a new stock belt and I over paid for that so I might as well get my money's worth. Link to comment Share on other sites More sharing options...
90 mj eliminator Posted July 19, 2014 Share Posted July 19, 2014 Hello, the shaft diameters are different between those pumps.The jeep pump uses a smaller dia.shaft.I used the Corvette accessory brackets on my ls1 conversion. Mike Link to comment Share on other sites More sharing options...
COFFMAN Posted July 20, 2014 Author Share Posted July 20, 2014 Ok, this is why I was trying to buy a complete P/S pump.. To remove and replace the plastic pulley could have always went south. IF the shaft dia where the same, it appears they are not. Having this in the back of my mind my initial intension are to fit the Camaro reservoir to the XJ pump ( should be correct fit ?? ) which is mated to the XJ steering box.. So I can get this sucker to turn key. Source the correct pulley to the new pump in due time... hence why a complete unit was the go. Thanks for the input fellows..

COFFMAN Posted July 22, 2014 Author Share Posted July 22, 2014 The latest.... Well ordered me pump approx. 1.30pm Friday my time. It arrived a my door step at 7.55pm Monday morning Unbelievable on ya FedEx :thumbsup: As previous stated I still had Pulley issues as in I don't have one. AND MY DREAM of the XJ reservoir won't fit the Camaro Pump, close but no cigar. So now ordering a pulley, trying to get details on the pulley shaft Dia should be 3/4in ?? The XJ pulley is OD is Approx. 137mm. I suspect the after market Camaro unit ( Turnone ) would be of a slightly larger diameter spinning my pump slower. What sort of headaches should I expect if I can't get a pulley of the same Dia as the XJ. Thanks Link to comment Share on other sites More sharing options...
Jeep Driver Posted July 22, 2014 Share Posted July 22, 2014 I wish you had posted pics........... You have thee fit issues....as I see it. 1, total diameter of pulley. 2, shaft diameter of pulley. 3, alignment of pulley. 1, if XJ pulley is 5 1/4" and GM pulley is 4 3/4" the difference may be 50-60 rpm at the pump......in my opinion that will not make much of a difference. 2, plastic pulleys have a metal sleeve at the hub, steel pulleys do too but may have more meat at the hub to be bored out to fit. Billet aluminum pulleys will likely have the most meat at the hub to be bored out to fit. If you order a plastic pulley to fit a 5/8 shaft and the shaft on your pump is 3/4, it will not fit as there is not enough sleeve to bore out. Image Not Found 3, Belt alignment will be the greatest concern IMO. Considerable difference in the pulleys from the 2.5 to the 4.0 for example. What will you do when the pulley needs to be moved out 1/2" or in 1/2" and you only have 3/4" of shaft to work with? Link to comment Share on other sites More sharing options...
Jeep Driver Posted July 22, 2014 Share Posted July 22, 2014 Here is a 98 Durango with a 5.2 V8........looks like a GM style pump to me......... Did you or have you considered all options from other models? Link to comment Share on other sites More sharing options...
COFFMAN Posted July 22, 2014 Author Share Posted July 22, 2014 I would love to post pics been trying for a week, that's another story (&*%$@ P/B The one issue I don't have is alignment, or should I say won't be to correct. I am using truck belt spacing. The ICI Billet bracket has a spacer Approx. 30mm thick that I can machine down. While playing around with the XJ pump and bracket, the spacer is to thick and I've been using washers to get alignment. When the Camaro pump and pulley is fitted the spacer will be machined for correct alignment. I,m keen for after market pulley so I can remove the pump without removing the pulley. As you pic shows no holes in original pulley. I was also suspect the offset on the XJ & Camaro pulley to be different, as I should not have to adjust spacer with Camaro pulley. The ICI Billet + Camaro Pump = Truck Belt Spacing. But I expect to dial in belt alignment. Thanks Link to comment Share on other sites More sharing options...
COFFMAN Posted July 22, 2014 Author Share Posted July 22, 2014 The XJ pump will fit and can be aligned, but due to the pump being rotated 90 Deg The reservoir filler is on the side. I could have done a remote reservoir on XJ pump. Don't really have the spare room. Or could have moved the filler on the XJ reservoir. Messy and would still have plastic pulley & 5/8 shaft Link to comment Share on other sites More sharing options...
COFFMAN Posted July 22, 2014 Author Share Posted July 22, 2014 This belt drive has been a major head banger apart from the water pump it is all custom. The LS engine was introduced in the Holden Commodore in 1998-99 with very little to nil changes in belt spacing. Our JY have no cool US iron sitting in them...lol Link to comment Share on other sites More sharing options...
COFFMAN Posted August 1, 2014 Author Share Posted August 1, 2014 Power steering pump fitted. Hope this makes things clearer for those that replyed :thumbsup: Link to comment Share on other sites More sharing options...
Jeep Driver Posted August 1, 2014 Share Posted August 1, 2014 The pump itself looks similar to the XJ/MJ pump, is it? Link to comment Share on other sites More sharing options...
Jeep Driver Posted August 1, 2014 Share Posted August 1, 2014 Let me ask you...... Dayco parts seem to be of good quality, I assume that they are more plentiful to in Australia, are you happy with them? Link to comment Share on other sites More sharing options...
COFFMAN Posted August 1, 2014 Author Share Posted August 1, 2014 The xj pump is very similar but not. The 3 bolt holes are the same, the inlet & outlet ports the same. The xj pump a little wider. But to bolt the xj pump up as the Camaro pump the XJ resivior filler would be on its side. So if i was to use the xj pump i would have to fit a remote resevior and machine a bit off the adaptor bracket, and be left with the plastic xj pulley. The Camoro pump was the only way to go just hard to get in Aussie ( impossible ) Dayco parts widely used on GM cars in Australia. The pump is a reco one. Would have, Should have brought a new, now i know what i know... live and learn. Link to comment Share on other sites More sharing options...
