xjustinx Posted February 11, 2018 Share Posted February 11, 2018 Been having issue with the belt being pushed forward on my water pump pulley about an 1/8 of an inch. Its definitely because of the new psc pump. I thought it might be because of the offset of the new pulley the pump came with so I swapped the Oem pulley on but no luck. Alignment still off. The belt is being dragged cross the water pump pulley ever slightly and causing a terrible squeek. I guess my question is should there be any difference between a 1990 pump and my original 89 pump? The psc kit was advertised for 90 and up. Link to comment Share on other sites More sharing options...
HOrnbrod Posted February 12, 2018 Share Posted February 12, 2018 2.5 or 4.0? The pulleys have slightly different offsets. Link to comment Share on other sites More sharing options...

DirtyComanche Posted February 12, 2018 Share Posted February 12, 2018 They're wrong, the change is in 91. HO bracket/pump/pulley is different than the Renix. You can mill the bracket down to correct it. Link to comment Share on other sites More sharing options...

I can't believe I'm the only person to put this pump on a Renix??? Link to comment Share on other sites More sharing options...
xjustinx Posted February 18, 2018 Author Share Posted February 18, 2018 Ok I took it all apart again to check out the bracket and do some measurements. The psc pump is infact about 4mm thicker than the rockauto pump that came off of it. Second is if this pump really is for 91+ what's the difference with the brackets. After doing some research I can't find any difference between the Renix and early HO brackets 🤔 Link to comment Share on other sites More sharing options...
HOrnbrod Posted February 18, 2018 Share Posted February 18, 2018 The pump bracket p/n changed in 91 (from 53002910 to 53007616) so there is a difference. I threw all my 91 pump mounting bracketry out when I swapped to the new intake otherwise you could have it. Link to comment Share on other sites More sharing options...

It's funny how they went to the trouble to change it so little. Link to comment Share on other sites More sharing options...
xjustinx Posted February 22, 2018 Author Share Posted February 22, 2018 Ok now the plot thickens. I stopped by pull-a-part yesterday and got a bracket off a 94 cherokee. When I got home and got both brackets next to each other I realized they are both different and exactly the same. The rear mounting post is different but all other dimensions on the bracket are the same. So now I'm thinking the pump PSC is including in their PK-1851 kit is not correct for any jeep they have listed. I just think the snout on the pump I have is just too long. I took a pic of the pump on the Jeep and the other is the pump I think I actually need, SP1210. Link to comment Share on other sites More sharing options...
hakukamana Posted February 22, 2018 Share Posted February 22, 2018 I have an 89' 4.0 eliminator, and my pump looks just like the bottom picture. It has the black plastic reservoir. The pump has a opening with an o-ring for the nipple off the reservoir. It also should have the pressure valve and spring where the high pressure line threads into. It also has two black clips that hold the reservoir to the pump. Link to comment Share on other sites More sharing options...
HOrnbrod Posted February 22, 2018 Share Posted February 22, 2018 Yep, Saginaw Type 2 (TC series) pump. All XJs and MJs (and YJs, ZJs, TJs, etc.) used variations of this pump. It your replacement pump doesn't have the same dimensions as the TC pump, it ain't gonna work on the Jeep bracketry. Link to comment Share on other sites More sharing options...

So what pump are they including in this kit? I'm guessing one for an LS motor? Link to comment Share on other sites More sharing options...
HOrnbrod Posted February 22, 2018 Share Posted February 22, 2018 No idea. Why don't you call PSC? I vaguely remember a post from long ago about the same problem with a PSC pump on a Jeep... Link to comment Share on other sites More sharing options...
HOrnbrod Posted February 22, 2018 Share Posted February 22, 2018 Here's an excerpt: https://comancheclub.com/topic/32740-alexias-1987-to-1997-comanche/?page=22&tab=comments#comment-490644 On 9/10/2015 at 12:34 AM, Alexia said: This is BY FAR the worst designed kit. After shortening the reservoir then cutting and modifying the mounting bracket I find out that the kit should have included two 45º*fittings instead of a 90º and 45º. Fine, whatever, so I look up the specifications on the reservoir since there are no instructions including detailing these things and order the -10AN 45º fittings listed. They actually use -12AN fittings and now I am having to pay for overnight shipping on the other fittings to get this MJ out of the garage. *Flips a desk.* In absolutely no way did PSC actually test this kit on a XJ like they claim. If they had spent even five minutes actually test fitting this they would have realized all the issues. The included -12AN and -6AN fittings hit the air box. Sliced, bent, and welded the mounting bracket to correct the angle. Added some spacers to move the clamp to the correct position. Link to comment Share on other sites More sharing options...
