I need some help working through the weeds on this issue.
I really would like to make this swap, as my box has a lot of play in it, and I would like to upgrade to a variable box, with larger internals to better withstand the force of 35's(and not spend 400 bucks for those on Quadratec etc.)
I have read through threads that the search returned, and to be honest, I cannot say that they have provided any clarity. For every confirmation is a refute, so I am asking input from those who have made the swap.
None of the data provided by any auto parts store show these items matching up, however, even CJ boxes between different stores show a DRASTIC variance in the specs provided. This is a part I will most likely have to special order and am trying to be as sure as reasonably possible. Any reason for the huge variances in the data?
My question to you is, which box did you swap out for? I have an '85 CJ7 with few stock items. I am running a chevy dana 44, I believe the power steering box/pump is stock, I have Saginaw 76(800?) box. Is this the box you swapped in the H1 box for?
If so, what difficulties did you have? Do I need any fitting adapters for the hoses(no specs I can find show the exact inlet/outlet fittings)
If not, which one did you swap the H1 box for? Thanks for the help as I struggle to make the right call on whether to order this or not.
Maybe the box is not stock. The "76" is stamped between the pitman arm and the end cap. Most of what I find lead me to believe they put this box on CJs. However I just saw another one that said its a popular swap.
Here is picture of the 76 stamp. I misunderstood if this is in fact a date stamp...
I was able to take a blurry picture, of the serial number(not worth posting) the numbers 5691676. This is a quick ratio box(approx 14:1) according to what comes up when I search. This explains the somewhat "twitchy" nature to the box i suppose. Looks like a GM box...guess its back to the drawing board. Any ideas on a swap with a variable rate? Looks like i could get the truck version of that box to move it to 17:1.
Guess this is the beauty of buying a Frankenstein jeep.
I have an H1 box on my CJ. The stock metric O-ring fittings are what fit it. It bolts right into place with no mods needed. I would pick up a new set of lines and a new power steering pump with the correct fitting on the back (just tell them its for a 1982 CJ7 and it will all fit.) That is the easiest way to get the pressure line to mount up. Otherwise you will need a custom hose with the flare end and o-ring ends.
Beat it to fit, paint it to match!
the cj came from the factory with saginaw boxes, I dont know if its casting 76, i could crawl under and look, the 76 is a 800 series box. JP may 2012 has a big write up on this. the boxes also came on pickup, with a four bolt mounting, which is heavy duty. not saying all pickup has this same box because some newer model have outside of frame mounts. my box on my 46 came from a 76 skylark
Thanks for all the replies, I just need to verify that I have the stock box. I know it's close based on everything I have seen. Seems like there is a slight chance the box on the Jeep was swapped for a pre-80s box, which would mean it uses flare fittings instead of O-ring fittings. However, I probably wont be able to figure that out until I remove the fittings. Even if that is the case, getting new hoses is probably not a bad idea.
Anyone know a good resource for original parts details(I will check haynes manual when I get home)? Or have/had a stock box post 81 that has the 5691676 part number on the gearbox?
