Awesome, now you just have to build the rear bar with swing out tyre carrier......
On my BJ they are tied into the same circuit as the window squirters; That being said they only come on occasionally so im not sure if they are designed to do that or if I have a short somewhere....
btw Truck looks awesome! A+++ job!!
thinking of doing anything else?

Yeah my headlight washers are tied into the same circuit as the windshield washers as well, although they do have a separate reservoir. They only spray when when using the windshield washers when the headlights are turned on. Perhaps that might be what you thought was a possible short??
Lots of plans and upgrades for the BJ74 still on the way. Will post more soon......
Nice job.
I would advise caution with the drop pitman arm, and in fact would advise going with the flatest pitman arm you can find. I still have the stock pitman arm, and have been wheel-locked in an extreme articulation situation... (traversing volkswagon rock in Rubicon in '06') The spring was so compressed that it was pushed right into the pitman arm, jamming it agianst the spring when trying to turn... very bad when you're stuck on voklswagon rock and you kind of need to steer.
Other than that... nicely done. I also like the axle moved forward. a must do on a 70.

When the lights are on and you spray do the lights ALWAYS spray? Mine only seem to go on every couple seconds if holding the arm back (and yes with the lights on)
Try pulling the wiper control arm towards you twice quickly. This will turn on the headlight sprayer for a couple of seconds.

I totally agree with all of the above advise for anybody doing a SPRINGOVER. Lift springs with the leafs under the axles, however, are great candidates for the drop (ie 60 series) pitman arm.

Yep, I really don't really care that much I guess.
I am with Peter on the preference for a flat pitman arm. I also prefer to locate the box so that a flat arm just barely clears the frame. This gives the most room before the spring hits it. your pitman arm will probably be the limiting factor for compression of your suspension, makes sense to make it as small a factor as you can.
I seldom play with non-SOA rigs that are not just daily drivers, so I am thinking about SOA considerations here
A factor seldom remembered is that a drop pitman arm puts a lot more stress on the bearings/sector shaft in the steering box than a flat arm does.

Nice Work, thanks for posting pics and details.

Well the transfercase was previously leeking, so it got removed and completely rebuilt. You can seed in the first pic where someone had gunked some silicone on the case where it splits apart.
I also took the shift tower off the main to have a look inside for wear, seemed fine.
Just for kicks here is also a pic of the toyota clutch beside one out of a Jeep YJ

With the PTO winch replaced by the electric and some noticeable wear present on the transmission output shaft spines that runs the PTO gear, I decided to eliminate the PTO completely. I replaced the two gears and spacer on the output shaft with this one piece gear.

Everything back together and ready to go in. I should mention while it was out I replaced the rear main engine seal. It was not leaking but when you are that close it just makes sense. That goes the same for the seal on the front input shaft of the transmission.
Obviously the flywheel was machined and a new clutch was installed as well.

I don't think that the shackle will stay that upright for long, I am sure the springs will sack out some and the angle will improve.Your help doesn't look too dirty
The rear shackles look too up and down to be right?
Great work!!!!Good looking Cruiser!!
When you had the t-case apart did you change the gears for lower low range...
may be something you want to look at! Will be a little fast in low range for serious
off roading. Here is link for gears that bolt right in.
Landcruiser Gears
Will be doing this to my rig over the winter.
One more little thing...you might want to start adding "stuff" at the back of the
unit for weight balance...been there done that..those things are heavy at the front..
not much traction at the back.
Happy trails

Yeah, I wish I would have put the Marks gears in. I looked into it but just didn't have the cash at the time. Definitely to fast for technical wheeling. I know I left some clutch in Moab.
As for weight in the back, it will be getting some more when I build the bumper / tire carrier and a system for packing my gear.

I added a Marlin Toybox and I really like the gear choices with 1:1, 2:1, 4.7:1 and 9.4:1. As far as rear weight goes, it'll come soon enough. My rig is way way way too heavy in the rear. I just pack too much junk with me. A couple of weeks ago I took off the Roof tent, FRP top, and took out the Generator, fridge, freezer, table etc. Wow what a different truck! It sits about an inch higher in the back, corners like it's on rails and seems to stop better than my 80.
Nice post, work and rig BJ71! I'd like to have one some day!
