power steering box

I’m putting in power steering on my 71 CJ-5 and need some help. I went to the pick a pull and got a pump and bracket off of a late 70 Buick and it bolted right up to the 225, the first question is does anyone know what part number/size belt I need for this setup. Also, I had a manual type box mounted previously to this swap out of a cj and I have the 3 hole bracket already mounted to the frame is there a power box that will work with the three hole bracket that I already have mounted?

Thanks in advance for any help,

Chip.

 

The 4-hole box will bolt to the 3-hole bracket, and vice-versa. The 4WD Blazer/S10 has a 3-hole box that's popular with the FSJ crowd. It has o-ring seals, so you'll have to have hoses made that have flares on the pump end and o-rings on the box end, or adapt your pump to o-rings. You can take the fitting out of the back of a modern o-ring pump to adapt a flare-nut style pump.

For the belt, I'd just run a rope around the pulleys and measure the length. Take this to the store and they should be able to get you the right belt. If they are familiar with the books, there's a listing by length. Might take a coule of tries. Should be a standard V-belt.

 

Thanks for the response, are they using the blazer pitman arm? Also if I make custom fluid lines can I not make one end o-ring type and the pump end standard compression?

Thanks,
Chip.

 

Hi Chip - no, they use the original arm from the Jeep box. Power steering in old FSJs gets sloppy, and replacing the box is an easy and cheap way to fix it.

Yes, you could make custom lines with different ends. Most people don't have access to the machine that swages on the ends to the high pressure hose. If you do, great; otherwise you'd have to pay somebody to make them.

timgr: Thanks for the help, do you know what year box I should look for? also, what does FSJ stand for?

53 Flattie: Thanks for the part number, I will pick one up tonight on the way home.

Full Size Jeep, like my truck.


Here's a link: http://www.ifsja.org/ubb/ultimatebb.php?ubb=get_topic;f=2;t=028499

 

FSJ stands for Full Size Jeep, as in truck or wagoneer. You can use any Saginaw power box that is out of a large GM car or a jeep box, the one other thing you need to check is the spline count and the shaft dia. off the old manual box as alot of the power boxes have a 13/16" x 36 spline, you're manual box probably has a 3/4" x 36 spline shaft, they make smaller spline power boxes but you will need to look to be sure, you really want a box that is 4 or more turns lock to lock on the steering box shaft.

 

ok, I've got a box off of a 2000 Blazer S-10 ($100 local yard) does anyone know which line the high pressure side is? I am going to clean and paint the box tonight and try to mount it to see what I need to modify.

i have had a heck of a time locating a box which is 4 turns lock to lock. i finally found an 80 wag box with 3 3/4. i am thinking it might be a variable ratio. slow in the middle for highway and street. quicker at the ends for slow parking and trail turns. i ask around here and everyone gives me that "deer in the headlights" look.

i have discovered that you can use a steering quickener from race shops and put it in reversed. instead of gettind a 1.5 or 2x quicken you'll get a .75 or a .5 slower turn lock to lock. but then your adding about $200+ for the quickener and the extra shaft etc.

 

JP or petersons did an article on that a couple of years ago. i was thinking about just that thing yesterday but i cant find the mag it was in. i know it was one of the first i ever got so thats what about 3 years ago.

edit: i do remember it was a Howe quickener and i found the price as of 2002 at $175 for the 1.5 to 1 kit.

 

if you find the article let me know. i'd be interested.

(didn't mean to hijack this thread. sorry. now, back to our regularly scheduled thread, already in progress )

 

I got the box mounted over the weekend and everything looks good. I do have a problem with the pitman, the one that came on the box will not work and the one that was on my manual box has the wrong size mounting hole. Does any one know what pitman arm might work for my application?

The NAPA 7370 work great for the PS pump.

I have the pressure lines mocked up and will have them fab'd today.

Stock CJ power steering arm. (Check the "hard core" boards, you can get these for close to free from guys that put drop arms on)

Be careful- I'm not sure if the S10 is indexed correctly.

 

what indexing should I check for?

 

I would use extreme caution if planning to use a quick ratio box or a "quickener" in a CJ5. With the short wheelbase, it's very likely you'll change lanes if you sneeze or blink while driving. I speak from experience. It's a good thing the 2.5 turn boxes are a lot less common than the slow boxes.

 

nah they put it in backwards. then it is a steering slowerer ( is that a word)

 

Mmm, I think the S10 box will be ok WRT indexing. The FSJ arm goes on without any trouble, and the J20 box is sometimes used as a "heavy duty" replacement for the CJ box, so it should be the same.

 

so does that mean i should be ok if i keep the stock arm that came with the 80 wag ps box it should mate with the replacement draglink/tierod balljoint end i will be getting from herm. ( a conversion from the two piece tierod to a long tierod single piece and a draglink to the pass. side tierod end)? or is the hole in the stock pitman going to be too large for the ball joint?

 

any injuries? hope not. yes, i was talking about reversing the quickener to slow dow response. what ratio box are you using now? i have a 3 1/2 or 3 3/4 lock to lock now. is that slow enough? can't tell if its variable ratio or not yet.
