I found the two fittings in your thread, are they for each end of the high pressure line?

I assume you are reusing the toyota return line fitting on the steering box.

Get those fittings (and the others you'll likely need) from PSC and run their "field serviceable" lines. You can make (and repair) the high pressure hydraulic lines yourself with a couple of wrenches and a vice (or just a couple of wrenches in a pinch):

I know this is an old post but... I've dealt a lot with hydraulic hoses, mostly in mining, if the crimp is done right, you'll have years and years and years of trouble free service as long as the hose isn't rubbing on anything. That's usually what does them in. They're pretty cheap and you can always carry a spare. I'm not a fan of the field serviceable ones, I just don't see the need when the crimp ones are so reliable and every time I see a hose leak or blow the ends off it's a field serviceable one. Only use I could see is if you wanted to carry a variety of ends and lines to make spare hoses for someone else but at that point might as well just carry different adapters and a prebuilt -6 hose with whatever ends crimped on (which I do).

Spare lines probably don't make sense for most of you, as you're not running hydraulic steering assist or full hydro but at that point field serviceable ends don't make that much sense either. Just run a crimped line from your box to your pump and be done with it just like all the auto manufacturers out there.

Just wanted to throw that out there...

Agreed, that is my plan. I was going to have two made, mainly carry the extra on any long distance trips where getting a replacement made maybe difficult. They take up very little room in the skeam of things.

This is my plan also. So I should know this, but seem to be getting conflicting answers accRoss the interwebs. Are JIC and AN compatible/the same? Those two adapter fittings convert the pump and box to -6AN. @maxamillion2345 in your thread you said you used JIC fittings on the hose you made up. I guess that mean a JIC female works with a -6 AN male? Is that right?
 
That's my bad. Probably should haven't kept interchanging like that. AN fittings are a 37* flare and so are JIC.

A 37* JIC and an AN fitting will fit together just fine. You could almost say they're the same... For our purposes they are the same. I'd probably just not ask about AN when you get your hose built as I think most hyd shops will only have JIC fittings anyway. Seems like when I see AN its only mentioned in race applications and aerospace stuff. AN is just a fancy super duper high grade military space ship JIC fitting.

But Yes, for us, they will work together no problems.

As for the ebay links to those AN adapters, they'll work but they're probably really only a JIC adapter.

Thanks for the clarification. Are the JIC sizing the same as AN terminology? In AN everything is divisible by 16 (-6 = 3/8", -4 = 1/4") does the same hold true for JIC?
 
@Wheelingnoob do you have the part number for the seal you used in the updated HF2A adapter? My adapter just arrived and I thought I had 2 of the right seals, but looks like I have the wrong ones as they are too big. The part number on the ones I have is 90311-50014.
 


The number you found is the change up number for 90311-48018 exact same as this one but the number you found is not easily found. The difference is the production date. The parts they seal did not change at all. I have confirmed that this earlier production part number works. The one I have used is in stock in most warehouses.

The belt tensioner I ordered will not work, it's for a 97 Dodge and tensions the wrong direction for this f800 accessory mount. So I will need to get another one.

I decided not to make my own tensioner mount I'm just going to buy the one from the same guy that made the alternator mount. At this point a saved day in this swap is worth more than the part.

I think I just ran into the same issue. My motor is a 97 6BT and the the tensioner wants to apply clockwise tension. Using the diesel adapter accessory bracket I think I need a counter clock-wise tensioner. Were you able to find the right one yet?

Yes I got a Cummins part number 3978021. Found a new one in box on EBay for $60.
