This conversion was done using wrecking yard components, with these exceptions, JT outfitters pump bracket, Farm Imp. pillow block bearing, machine shop drill and taper new hole in Pitman arm. Lower column bushing from Wardens...
Butch

The gear box and pump are of course IHC Scout, bought from a Jeeper buddy that was wrecking one out after getting the axles.....good source, as they never use em.
The rag joint and u joint are IHC that came with the box.
The slip shaft and upper U joint are RWD GM car, most all of them had them.
High pressure hose is made by a local parts house using the scout ends, the OEM scout is way too long.
I really like to incorporate a slip section and rag joint, just to isolate road vibrations from the steering wheel.

You can grind and cut the OEM shock tower, to clear the box, but it looks like shit, after you do all of it, so its better IMHO to make a new one.
A scab plate is fabbed up for the inside of the frame, and sleeves are utilized and welded so the bolts won't collapse the 2 sides, and they will stay tight, Grade 8 bolts and Nylock nuts hold the box in place.

I used a very non technical method to decide the length of the pitman arm, but it seemed to have worked well, I measured the length of the steering arms, and made the Pitman arm close to the same length, A local Machine shop drilled and reamed the hole to fit the LC tr end.

The radiator frame and shroud must be notched as seen in this shot, you loose the lower bolt, but Toyota saw fit to have another one a few inchs above it, just have to drill the shroud for it....

Maybe you can tell from this angle how much inner fender must be trimmed...
I think actual $$$ spent on this conversion would be around $225
and 100 of that is the JT bracket, I probably had 8-10 hrs or so in it...
Butch

looks good, but can i ask why the scout box instead of toy IFS or FJ60/62?? its not like scout is more common or anything. is it just for saginaw?

Saginaw power, but it's not in the way of a PTO or one of the larger electric winches.

You know that a regular GM pitman arm will fit righr on the Scout box.:rolleyes:

Is that lower block bearing support really necessary? I am doing a similar setup with my J60 power steering swap and wasn't going to use one of those support bearings, will this cause a problem?

how many bananas do you think this route is versus purchasing a kit? I'm facing a PS conversion on a '74 in the next month or so....


:eek:

I understand that cost was an important consideration in this conversion. Just to throw out another alternative, I have done the same conversion for a friend, but instead of using the rag joint and pillow block I used a Borgeson double-D slip shaft with a needle bearing joint on each end. It is a bit more $$, but I think it provides a cleaner configuration, for whatever that is worth.

I've done 3 Scout PS converisions and have never used a spud shaft or a pillow block. I used a 36 spline x 13/16 universal joint from Flaming River. Looks sweet.

Butch, the first time I did scout PS on my 55 with Bill Jackson, he used black pipe through the frame to support the three bolts. A year later the tubes had all started pulling through the frame. So Mudrak re-did the mount, with a big-ass plate on the inside of the frame, welded again to pipe passing through the frame for the three bolts.

Mo betta.

Morgan

Morgan we do have a scab plate, which the sleeves do pass thru and are welded, the bolts actually tighten just on the sleeves.
Yes I tried several GM pitman arms, but none that I had here looked long enough or had too much drop, and the straight flat one was too straight to suit me.
I know about the borgenson joint,($$$) but I have used the brg. on several Saginaw conversions and they are holding up well...

RHINO asked.....

The toy PU box, keeps all the extra linkage and pivot arm up front..:(

I don't think the FJ60 box is as stout as the Scout, plus have you seen what these things go for on Ebay etc??????
Ask Tom Pennington..........he's on here....

I am currently running a fj60 box. I was running 35X15.50 SX's with a Detroit EZ locker in the front and with the toyota PS pump it sucked. I puked more fluid on the trail than I care to talk about. After I replaced the stock pump with a saginaw pump things worked great. Even in Moab with those FAT tires on the slickrock it did great. No problems at all.

I have had the steering box rip off the frame in Poteau, but that was MY fault. Ever since I rebuilt the scab plate it has been rock solid.

All that being said, the real test will come next week when I get rolling after a SO, SR, with fj60 axles and 38X14.50 SX's. To be honest, I have my doubts about the fj60 box being able to handle it, but we will see...............

And to answer your question..........
Typically the Scout set-up is MUCH cheaper and easier to find. I just happened to come across the fj60 set-up on a wrecked truck for a fair price.

Cheers,

thanks guys i got some good info here:)
i currently have a saginaw pump on a homemade bracket, and my power box is the early push-pull mini truck box.(very easy swap) i run 36" sx's and i havent had any probs with lack of power or puking on the trail, it seems to work very well for me, except the extra free play from the darn center pivot like thing whatchamakallit. so i'm getting ready to do another box to elimate this. i was going IFS mini, but maybe i will go scout instead i know where a few are. i dont like the pillow block or rag joint personnally so i'll have to get out the ol' tools and see what can be done.

hey deisel_cruiser, you dont need the pillow block or rag joint on your steering box, thats an american thing. i beleive maybe i can get backed up here, that your u joints from the 40 are interchangeable with the 60, you will need to lengthen your steer rod between them though. this was one reason i was going witha toy box instead of saginaw, but my plans just may be changeing.

sorry for the winded reply:D

BTW tex this is what i have now, but the IFS mini is excactly like the FJ60, and thats what i was referring to in my Q but i see the benefit of the scout box.

I talked to the guys at Sunray and they will tap your FJ-60 box for you so you can run Hydo assist.

I would go that route with 38's for sure.....

You can also tap a Scout for hydro. There's a rig up here running a scout box with 4 wheel hydro running off a scout box.

:D :D :D

My only concern here is that you are still locked into a relatively rare and expensive gearbox should something go wrong, A reman. Scout box, with a lifetime warranty,( have no idea if the tapping for the ram assist will void this) is $159 exchange.
Last time I priced an FJ60 box it was over $400 reman.
West Texas Off Road will drill and tap and rebuild any Saginaw box, for a very modest fee all at the same time.
just my $.02
Note to Rhino, I thought by mini box you meant using the bracket that bolts the power assist box in the same spot as the OEM box, have not seen the type system you are talking about...........

Hey whazup, Butch. Its Worley from Knoxville, Tn. How are you, Christy, and the gang?? Anyhoo, Im running the FJ-60 box. Drilled and sleeved frame. FJ-60 pump. (New pump) My old one also puked fluid out like fj40 tom's. Anyway. replace that and also heres something else you can do.. run synthetic power steering fluid because it allows for a higher boiling temperature.

Worley

this is nice but I think you have the makings of and official tech write up here Butch. If not on PBB, maybe on Woody's site. as always, i really appreciate the sharing of info and opinions here. :beer: :beer: :beer: :D

now, from what i know about the boxes(which is little), you could pick up a bad box and use the end plate from your used box and trade in the warranty'ed item if it ever went bad, not that i would rip off a warranty!:flipoff2:


sound do-able?

Hey Dude!!!
We are all fine, we went to Moab this year, we also run PS coolers on all the rigs that are locked up in the front, it helps bunchs.....
I think I'm going to wright it up for the LSLC newletter which will go on our web page, we will then have all 3 common PS swaps up on our page, all done by members of LSLC.
