I'll soon be installing my full hydro steering. As I prepare for the installation, a few questions arise...
For anyone currently running a PSC p-pump conversion kit on a I-6 ZJ, what length serpentine are you running? If it comes down to it I'll measure once it's on and go from there but it's nice to have the belt before beginning.
Now the more difficult question. I'm running a Parker Hydraguide orbital with steering coulmn adapter SKF000780400 that lists as 7/8" X 36 spline. I need to somehow connect this to my existing stock steering column. The stock spud shaft seems much smaller than the parker column. Does anyone know the stock spud shaft size and have any ideas on how to connect the steering column to the bigger spud shaft on the orbital (other than permananet means like welding)?
Basically I need something like the solid coupler pictured here only for 7/8" X 36. Then I can do a hack and weld on my steering column...

Anyone know of any sources?
i'd make a new shaft. use one end frm the Stock ZJ and the other for the orbital.

When I ordered my setup from Crawltech, they set me up with a the correct size spud shaft adapter, I hope. I can get you the part number for that one if you would like. We will trying to put this together this weekend. I have the same question about the serpintine belt as well, because the PSC pump pulley is a bit smaller.
Yeah, get me the part number if you can. I'm calling the plave I got the steering column from to see what they've been recommending.Originally Posted by Tommy
I'm more worried about the spacing of the p-pump conversion kit. Does the kit space the pump/pulley out farther than stock? Also, can you remove the pulley from the p-pump and the stock and swap them? That'll give the same size as stock but once againt the spacing may come into play.
I spoke with PSC. What they do is machine the Parker steering column to be 3/4" 30 spline which will connect right up to the stock Jeep steering column. This seems to be the easiest thing to do. Wish I knew that when I bought the steering column last year but there weren't many shops providing full hydro setups then.
I am unsure of the ZJ, but on TJs you need about 3 inches forward of the pump and about 6 inches towards the driver's side to fit the p-pump in. This requires either swapping in a smaller coolent overflow reservoir, or modifiying the existing one. It also requires swapping in a new window washer fluid reservoir or moving the pumps. Here is a write up to get you started:Originally Posted by Troy

The pulley should be the same as stock, you would have to ask PSC to confirm. I have a PSC TC pump, and I was going to put my stock pulley on it, until I pulled it apart trying to press it off. I used a stock replacement. The p-pump moves the pulley to a new location, so you will need a new belt no matter what.
Are you set on the p-pump? I thought about it, and ended up with a hi-flow TC pump. I know some guys in CA who run a Howe Performance TC pump, with hydro assist and hydroboost with no complaints. Give them a call and ask about the "Blaine special" pump and see what they have to say. FWIW I am using the Howe reservoir, swapped it out from the PSC one I was using before, I think it is a better design.
I have had the PSC P-pump for about a year now (not installed obviously) so the Howe is out of the question. I have done a conical air filter conversion to free up a bunch of driver side space. Thanks for the info. I'll be installing everything the first weekend in Feb. And I'll post pics if I remember to take them.Originally Posted by TJeeper
No to mention the the punp that I recieved from CRAWLTECH bolts in the stock location. TJeeper, just curious where yours moved to? That is why I was curious about the pulley. When I pull off the stock one this weekend I will compare the two. And here is the part number of the Eaton Char-l-ynn that I have 204-1002-006.

Did your P Pump conversion kits not come with a belt? Mine did when I got mine a year or two ago. No longer have the Jeep, so I can't get you a part number.

Nope.Originally Posted by JpRngr
Nowhere. I have a TC pump, bolts in the stock location.Originally Posted by Tommy
Maybe I just misunderstood your post then.
"The p-pump moves the pulley to a new location, so you will need a new belt no matter what."
I didn't understand how the pulley moved to another location when the pump bolted up as does a stock one. But come to think of it, without the res. on the pump now it probably does.
The p-pump is actually moved further out from the heads and block because of it's size. It has a bracket that mounts in the stock location and locates the pump further out. Hence the reason for the new belt.
After thinking about it now, I realise I didn't actually get a new belt with my kit. I re-used the old belt but w/o the A/C comp. I always figured that if I ever put the comp back on for OBA, I would just figure out the size difference for belts on engines with and w/o A/C, and add the difference to the A/C belt length I was using.
Also, on a side note, if you're installing this kit on a V8(like I did), some modification will need to be done to the mounting bracket. You will also need to use PSC's Ford SuperDuty pulley. The V8 pulley is 7 rib and the one in the kit is 6 rib. The SD pulley is 8 rib, but can be lined up to work.

We got the ram mounted and pump installed. Everything is just about done. I did notcie that the PSC pump pulley was much smaller (abouit 1") and was missing a rib on the pulley. But my pump did not come with a relocation bracket. it mounts in the stock location. I put the stock pulley on the PSC pum p and my belt lined up just like stock. I know the pump wont work as efficently with the stock pulley as it is a larger diameter, but do you guys think It will be fine to run it and see how it behaves? I need to take some pics. We were really surprised on how smooth the install went. Mounted my orbital around where the original steering box was located. And with the adapter it mated perfectly with the stock steering shaft. Looks like they forgot the fitting in my kit which goes from the resevoir to the orbital, so I am going to get one made from a local shop here. Other than that we just have some more plumbing to do and finish up the small push bar and skid for the ram.

Cool. I'm installing mine the first weekend in Feb.Originally Posted by Tommy
Just FYI. What i got from PSC.
The pulley will work fine and you should be able to find that fitting at any hydraulic shop
Let me know if you have any problems.

Hey Tommy, are you sure you got the "P" pump conversion? Cause it's a lot bigger pump and won't mount in the stock location without the additional bracket, at least not on the V8. My guess is you got the hipo TC pump.
Corey
Thanks, we we have a power steering pump puller and were thinking of using it if necessary to swap the pulleys. I have all of the fittings I need so I should be good there. Are you not installing a cooler in between the orbital output and the return to the pump? Make sure that your orbital does not get hot because it will fail.Originally Posted by Tommy
I didn't put in a cooler. We will see how it does, i can always add one. I had asked PSC about a fitting on the bottom of the resevoir . They forgot it in my kit. Corey, you may be right. I saw the differnce on the PSC website. This is what crawltech sold me, in the kit.

Here are the pics. excuse my wiring for my rocklights and ARB. I had to move a few things around and need to clean it uop a bit. We plan on also plating some of the skid for the ram.
What a fucking difference, this thing has the turning radius of my old 3 series beamer. It takes some getting used to when driving it, way easy to over correct. I see myself driving this thing to the grocery store to get some toilet paper and beer. Maybe...
Need to paint all that stuff before it turns to rust!
