Nice work Rich. Have you set a completion date/wheeling test yet?

July 21st we're taking it out to the "playground" that was in last month's Crawl mag...

But I better test it a little before that, lest a bolt fall out or something dumb...

Tapage - yeah, she does, but they're NOTHING alike.. Sorry!
 
small update.. the pinion brake and steering will be on the front side of the rear axle.. I'm very happy about that.. didn't think it would fit before, but it does... I winched down the rear suspension to the bumps and there was still a bit of clearance between the link and the rotor... so I got to go and swap the knuckles around to put the steering arms on the front... fuuuuuun.

In all build are included an small shot of luck !
 
hey dude,
kind of unrelated to your build - looking great though by the way.

but do you know if when doing a coil conversion on an fj40 using the stock housing, if you need to do a cut and turn as per the SOA conversion when using the leaf setup?

please note, that using 80 series axles is out of the question.

You should plan a trip to Crozet when done too. Alot of fun to be had there. Got my 1st roll there this past weekend.
 
Kiwi,

The cut and turn is for the pinion angle and castor. If you can mantain a good castor and pinion angle you don't need to cut and turn the axle. More then likely if you are going to point the pinion at the TC, on a short wheelbase, short drivetrain rig you will need to do a cut and turn.

This week's update - I'm almost done with the fabrication portion... finally! Had a friend come over Friday night and we made all 9 of the hydraulic hoses. Still waiting on some of the adapters to come in before I plumb the rest of it, but the hoses are all made. Probably going to carry a spare in the toolbox.

Got the power steering & transmission cooler mounted up.. Was a pain to find somewhere where the tires wouldn't throw things at it, or where they weren't too close to heat. The fan blows up from the bottom, and the hot air will exit out the louvers in the hood..

Did the Holley multi-pickup kit also, center of the cell, one at the front, one at the rear. This is just showing the mockup.

And, the rear area is complete.. fuel cell & cooler are mounted. Amazing how fast the room got eaten up!

decided to put the rear steering ram on the back side of the axle, as it let me use the hi-steer arms, and I'm less likely to get hung up with it there vs. on the front of the tube.

Also made a guard for the pinion brake, complete with speed holes..

Did you make your lines or have them made somewhere? I need to get going on mine and I'm trying to find a half way inexpensive way to get them. The reusable ends look to be some decent $. I'm thinking of using the pre made lines Surplus Center sells as they seem to be pretty decent on cost.
 
Friend of mine's day job is forklift repair, so he backed his truck up to the garage, and we had at it.. he's got the crimper on-board.

Check out Discounthydraulichose.com - that's where I'm buying and have bought a bunch of adapters and stuff.. Their reusable ends are pretty cheap.

I would suggest trying to use 100R16 hose if possible, it has a nice tight bend radius.

My friend's company uses Parker stuff which is the most expensive s*** around (of course), so I spent more than I wanted to, but not having to leave the house was nice, but he also uses the standard 100R1 hose, which has double the bend radius of the R16, so curves are being a PITA.

Only thing to remember is that the hose and the hose ends need to match, i.e. Parker with Parker, Gates with Gates.
 
Dude you work as you have a complete team working for yoy ..

Q. did you have tranny cooler and PS cooler one on top of the other one . ?

I have the idea to place it rear .. have more space, lees heat.

I *WISH* it was more than just me many times... Like when I'm trying to install the NP205, or working with Rockwell parts...

The trans/PS cooler are here: https://forum.ih8mud.com/showpost.php?p=2264568&postcount=164

They're stacked together, with the air flow order being fan --> steering --> trans cooler.

There's really not room for it anywhere else on this rig because the coolers are 12x12", then add room for the fittings and lines. The air temp going in shouldn't be too bad, since the sides are totally open..

Still thinking on that .. and thought more longer hoses add stress to the pumps on tranny and PS ..
Don't get me wrong .. I'm not saying that your plan positioning it in the engine room are bad .. naap .. just wondering there another place in the rear just to keep it far away from the engine heat and alloing your engine have more " space " to be cool.

But again I'm always forget that you don't have the same eviroment temp as me .. :eek:

Your temp are not a radical issue as us .. down here.
 
Oh, it gets plenty hot and humid, but ya have to remember that I have no fenders, or aprons, or anything, it's just the hood that keeps all the engine heat from escaping. The PS system I'm not worried at all about adding stress to, but the transmission pump I am, somewhat. In the last build, I had the transmission cooler off to the side of the radiator area, and the transmission hot line never got over 140-150°

Not alot to update, made the mini tie-rod ends for the front and welded up the slugs in front the steering arms, did some painting on the rear axle pieces and the rear tubework, and started installing the engine wiring harness. Once i figured out why Jim's laid out the connectors where he did, it all made sense.. All the wiring is pretty well hidden, it's a nice harness he made.

Now to figure out where / how in the hell to mount the computer.. I think I have a location, but the PCM has no provisions for mounting..

I'll snap a picture of the front steering once it's fully assembled.. it's freakin BEEF.. the pieces from Station are nice as hell...

I have been at the beach all last week so nothing got done, and all I got done today was to make a parts store run, paint the rear axle hi-steer arms, make the rear tie-rods, do (very) little on the engine harness, and mostly scratch my head, resigning myself to having to run a Camaro water pump because of the water pump's outlet, if I want to be able to run an air filter...

Oh, and I also disassembled the front coilovers to add a 90° fitting to the reservoir hose.. My first time tearing into a set.. Kinda nerve-racking! Not to mention, a little messy. But, all went smoothly, and once I got over my own timidness, it was actually pretty simple. Also added the Jeep TJ bump stops on the shafts while it was apart. Just getting the rig high enough to disconnect the coilovers was quite a freaking adventure. :rolleyes:
