I know this is an older thread, but wanted to let everyone know I just ordered an H1 box from JCWhitney online for $152 (with a coupon code found online). With the core return, ends up being $122 if I actually decide to return it. I was thinking about doing a J20 upgrade on my CJ7, but with the bell coupler it would have been the same price as the H1.

Waiting on UPS now!

Both gearboxes have 13/16" diameter input shafts with 32 splines each.
Hi.
I am doing the swap, but the umbraco screw broke on the Borgersom steering shaft so i have to buy a new u-joint to my steering shaft.
But, i am not sure what size to buy, is it correct that the splines on the inputshaft on the steering box is 32? I cant find that count on the Borgerson website.
(I am swaping a oem power steering gearbox with the H1 box)

UPDATE:
I sent Borgeson mail and they said that it is 36 splines on the 86 Cj7 w/power steering. They told me to order the vibration reducer #034940 ( 3/4DD X 13/16-36 )

^---update:

I just finished yesterday installing H1 gearbox I had a bit of trouble locating one and went with a 2001 H1 box from autozone for a tad less then $200 after core.
The box came with new O rings for my power steering lines and they actually fit so I used them. I installed the Zinc plated HD mount from MORE and there brace kit. I installed a new HD steering shaft Borgeson with vibration reducer from morris Thanks to them I got a discount code in my E-mail and deleted it by mistake before my order and I asked the guy in chat if he could hook me up and he did give me the code for $10 off so thanks morris. Everything bolted right in fairly smooth (Its a jeep so it betrayed me a tad) . I bleeded the system and started the motor to find no leaks but have not driven yet due to my jeep running like crap and stalling while cold, kinda leaning to a howell problem to lean while cold. Idles great when fully warm.

I did this swap a month ago.
The Jeep feels way bether, but i have noticed that there is a slack in a couple of millimeters between the 13/1 to 16/1 gear when i am driving on the highway. I thought this should be a smooth transition, but i have to turn the steering wheel a couple of mm to make it turn again.
This is when i turn both to left and right.

Have anybody noticed this? Or is it my H1 gear box that is defect?

A couple mm's could've anything from slop in the steering shaft to ball joints, bearings or tie rods. It could even be something as small as tire flex. I would doubt there is anything wrong with the box. If you are looking for steering that tight you won't find it in a jeep.

Thanks for the great thread. I did the H1 box repalcement on my 86 CJ7 with a HD steering mount/brace etc. Works great and feels tottaly different than the old stocker that leaked constantly. The new o rings in the kit stoped the leaking and it feels so much safer. Takes a little more effort than the old box but that could be from the axle swap and bigger tires.

Best price I fould was Advanced auto. After core exchange I was under $200.

pitman arm ?

So I also did the H-1 gear box and would like to run a Borgerson bendable pit man arm as my old one had to go with the return (1978) and if so does anyone have a part number for a 6" center on center. Thanks Keith.

Getting ready to replace my steering gear with the H1 part and thought I'd go ahead and replace the hoses, and probably the pump too.

But nothing is ever easy in the world of CJ.
I go to the NAPA site to order hoses, and I'm presented with the option for hoses (both pressure and return) with and without "Electrical Switch Port" whatever that is.

What's that all about, and which hoses to get?

I have no idea what kind of electrical switch port they are talking about, so my thought would be to get the one without.

The hose with the electrical switch port was for the 4 cylinder equipped CJ's. The switch would energize a solenoid to bump up the idle speed when the steering wheel was turned full lock. Pressure would increase and stall the engine without it.

If you have a L6 or V8 engine, you don't need it and never had them.

colt,

to buy or see and compare, check out the pressure hose and return hose for your Jeep (1983) here:

click on No. 11 "pressure hose" and will take you to a list. The return hose is there also.

Cheers
