Sab-a-dab-a-doo! The back-country LJ build has officially started

Oh wow. That's a lot. I just used a pole jack with a wood block of different shapes on top (red arrow). I did screw up in one spot when the jack slipped and poked a hole in the sheet metal which I just painted, siliconed and taped over (blue arrow)

The four speed is the culprit for me. The planetary assembly pushes the main Atlas body back about 6 inches. Your bump-out is in front of the raised section that the front seat bolts go through. Mine is behind it. That's a big difference because in front, like yours, it's not two layers of steel sheet, as it is in the rear, like mine. I learned that the 6" difference between the two speed and four speed Atlas lengths is not a trivial difference!

That makes complete sense. Even in my case, I was right up against the double layered area. If I'd needed any more, it would have been much more difficult. Although the 4-speed would be very nice, the length of a TJ kinda rules it out or at a minimum makes its more complicated than I wanted to attempt.

Yeah, I think I commented to Mr. Blaine during one of his "coaching" sessions via the phone that I don't know how someone would fit that in a TJ and not have issues with an incredibly short drive shaft. This picture, pulled from the "Installing a Atlas 4-Speed Transfer Case in a Jeep Wrangler TJ" thread here is what a TJ rear driveshaft looks like with a 4 speed Atlas :oops: :

The other complicating factor that requires even more tunnel massaging to fit a four speed is that because the case sits 6" further back, you have to raise the transmission even more because the transmission angles downward in the rear, so as you move it back, you have to also raise it to keep the bottom of the transfer case off the skid. That means more tunnel bumping!

If you've looked through my build, you'll notice I took advantage of every modification I could to make it fit. I countersunk the oil pan cover screws on the Atlas and used flat-heads, and I used a die grinder to cut a pocket in the skid plate to give a bit more clearance to the lowest corner of the Atlas. That thing just barely fits in there. In fact, I have shims made to adjust the height in case the rubber mount sags more.

I'm glad no one told me how much work it would be to put a four speed in because I might have been too lazy to tackle it!
 
Yesterday, I started on closing off the tunnel for the transmission and transfer case levers. I'll post more on that shortly, but first, in anticipation of putting the interior back together, I pressure washed the carpet this morning. I hung it out side on a line to let most of the water drip off all day, and then I moved it into the shop on a make-shift clothesline this afternoon:View attachment 612120

Back to the close-off project. Yesterday, I cut some .060" thick adhesive-backed foam to put on the block-off plate I made last weekend (to hopefully seal it from hot air attempting to come into the cabin):
View attachment 612122

For the first half, I cut it out first using a pattern I transferred to paper, and then applied it, as shown above. The second half was a bit more complicated due to the clearance hump for the Atlas twin-stick tower, so I just stuck the foam to the plate and then cut the edges and holes (holes were cut with an ordinary paper single-hole punch.) Viola:

Also yesterday, I installed the 10-32 nutserts needed to install the block-off plate:
View attachment 612127

And that wrapped up yesterday's build activities. This morning, I was occupied by another project - the battery for our fancy zero-turn mower. I can't keep batteries alive - it will last one season even with a smart charger on it whenever it's not in use. Every spring I have to buy a new $75 sealed lead acid battery. I've tried three different chargers on different settings, and the results are always the same - a dead battery in the spring. I had to drive into town to get a new battery for it. :mad:

Mid-morning, I started back in on the LJ build. I had not replaced the stock nutserts around the block-off plate because I thought I'd be able to use them, but they didn't work - they were spinning when tightening the screws. I tried using the nutsert tool to pinch them tighter, but the that resulted in stripped nutserts. I think they are 10-32, but maybe not? To remedy the situation, I just drilled them out and replaced them with new 10-32 nutserts. Then I put the transmission block-off cover and the new transfer case block-off plate I made on:

Finally, I used self-tappers to install the boots on the Atlas twin-sticks and planetary levers:

I'm getting close to starting in on the axles. However, I don't think it'll happen next weekend because I'll likely clean the interior and then start installing the carpet, seats, and center console. Stay tuned!

Looking great!! Clean install — as always.

For the zero-turn battery, do you run a trickle charger?

In the early years of my riding mower, I killed a battery within the 2-3 years. With a new battery and it being stored in my garage, I kept it on a trickle charger all winter long. Battery lasted 8-9 years.

This spring, after 2 winters being stored in the new shed, the battery wouldn't start the mower. (pulled the TJ's battery and used that to jump the mower....) I put it back on a trickle charger and it's showing charged - got to try it next mow to see if it starts up to see if I get a season more out of it...

In the future, I'll pull the battery into the garage and toss it on a trickle charger over the winter.

Yup. I grew up in the great white north where we always had vehicles on chargers in the off-season (snow equipment in the summer and everything else in the winter). It was far cheaper to put a charger on each battery than to buy new batteries each year. I bet I have over a dozen chargers in various places here on the homestead. I actually tried three different chargers on various settings for the zero-turn over the last few years, and I even had a brand new spare battery for it on a charger in the house all winter. That one was bad, too, when I pulled it out on Sunday. However, all the batteries I've been trying the last few years are sealed AGM batteries, and I found out today at the battery place that they aren't a good choice for engine starters. I just put a wet lead-acid battery in it tonight. We'll see how that one lasts.

Can't speak to the difference on a zero turn but for my riding mower I went with the lead-acid from Napa. Napa's been my go-to, since Sears went bust, for reliable batteries I know I'll beat on (like the Jeep or mower) where they may run low, lots of start-stop, cold temps perhaps without a charger or start often, etc.
DD get a Walmart EverStart - and they've been good in the 2 DD's I've put them in.
 
Work on the cutting brakes continued today. I started on the hard lines for the bottom side of the tub. The first task was to install two pair of mounting brackets. I'm installing rigid lines from the bulkhead fittings on the bottom of the tub behind the cutting brake master cylinders to just above the Savvy rear upper control arm mounts on the tub. Then, there will be flexible lines from the bottom of the tub to the inside of the Savvy rear upper control arm mounts. Those flexible lines will allow me to raise the body off the frame a bit for maintenance without having to disconnect brake lines. I had SendCutSend make some brackets I designed for the outside bottom of the tub and the Savvy rear control arm bracket. I mounted them using two 1/4-28 button head cap screws per bracket. This picture shows the two brackets (OD green) with -3AN bulkhead fittings installed on the driver's side:

With the brackets and bulkhead fittings installed, I started on the rigid lines for each side by cutting them slightly longer than I expected. The jeweler's miter cutter arrived during the week, and it works really well. The first step is the cut:
View attachment 604711

Followed by filing it square:
View attachment 604713

The tool steel used for that tool is very hard - the hacksaw and file don't touch it! Deburring was done using a stone on a rotary tool, and flaring was done using the Rigid tool, just like my previous post. Using this method makes really nice flares. This is the best picture I could take (I'm not a photographer):
View attachment 604723

I bent up the driver's side line first:
View attachment 604724

Then I bent up the passenger's side:
View attachment 604725

And here's a shot looking straight up at the bottom, showing both lines:
View attachment 604726

And that was it for today. Tomorrow, I'll work on the rigid line from the combination block to the center bulkhead fitting in the picture above. Since that line starts and ends connected to the body, no flex lines are required. It'll be one long rigid line.

I also measured the length needed for the flex lines from the body to the Savvy rear control arm brackets on each side and ordered those. I'll install those next weekend, and then start putting the underside back together.

Dang that is very well done

Yesterday was spent designing some rainwater collection equipment for the homestead, so no progress was made on the build. Today, however, I made a wee bit of progress. I got the carpet and front portion of the center console installed:

I can’t install the rear of the center console until I figure out how to mount the new subwoofer in it. Stay tuned!

What carpet did you go with? I'm thinking it's about time to get carpet back in mine after 15+ years without...

That's the OEM carpet. It was in excellent shape, and I just shampooed and re-installed it.

I forsee the kids working at shops staring dumbly at the console before going back inside to find an old guy to drive it onto the lift 🤣
The only way this LJ will see a shop is if I'm incapacitated and unable to do the work myself. I don't trust anyone to work on it. The skillset of the average mechanic is pathetic these days. I wish that wasn't the case because one day, sooner than I'd like, I know I won't be able to work on it anymore. :(

Same. What about tire shops? I've had kids stare at the shifters in my trucks several times and turn around to go find a grown up. They can't even do tires right these days though. I want to at least get a good used balancer.

I installed the tires myself because Discount Tire won't touch them:

And then I forgot to add the balancing beads, and Discount Tire wouldn't even balance them, so I had to go to a small tire shop that did it for me, but I brought just the wheels/tires to them.

One of the best parts of living in Arizona is the local Llanteras(mexican tire shops). They will Mount anything on anything.

That photo is insane. You hear "short driveshaft" and then you REALLY see what "short" means.
