Look what got here today

Hopefully you can get that triple shifter bracket in there without any more trouble then opening the existing hole a bit wider. Mine was kinda nightmare.

Welcome to doubler club. It’s fun here

 

[GLTHFJ60]

It's going to be real tight to get the shifter box in the same place that the current one is in. Was thinking I might need to keep my dual shifters for the transfer case where I currently have them in the floor, and actuate the doubler with a pull cable off the dash or something.

It's all about driver comfort. My controls are all very comfortable where they are currently, but that third shifter would likely throw a wrench into the works.

We'll see. Current transmission and transfer have to come out first, reseal the transmission, make sure the transfer is clocked the way I want, do some work to the shift rails on the NP205, etc. Have a few projects to knock out before I start tearing moonshine apart though.

 

[GLTHFJ60]

Since I have an ARB compressor, maybe I'll find a pneumatic actuator to actuate the ecobox. That would be pretty slick. Maybe something like this. Thoughts? Seems kinda crazy, to me, but it would be easier than fabricating custom shifters.

 

[GLTHFJ60]

Double-acting might be a better choice. I'm starting to like this idea.

You might be able to clock the crawlbox so the shifter is at the top and use one of the transmission cover bolts as the fixed point for the cylinder.

Am I remembering correctly that you thought about using a pneumatic cylinder for shifting your 203? If so, why did you decide not to go that route?

Yes, you’re right I did.
I scraped the idea because I was only thinking about doing it if I was doing all three linkages pneumatically. And that got expensive, three sets of lines and fittings, three cylinders, and an air system which I didn’t have at the time (still don’t) I was broke at the time and compared to making normal linkages it didn’t make sense. Those ended up being a ton of effort and never worked... cables are best from effort for result standpoint obviously.

The other thing is I didn’t feel like calculating three different sets of motion ratios and levers to acount for the travel of the air cylinders.

You will need the three position cylinder if you go that route.

There’s a couple guys with pneumatically shifted 203/205 combos on Pirate if you want some inspiration.

 

[GLTHFJ60]

A single pneumatic shifter should be pretty easy to figure out. I'll look into pirate, thanks man.

Edit: Yup, I'm doing it. Twin stick cable shifters for the 205, pneumatic shifter for the doubler.

Moonshine was in Toyota trails with a photo by @Green Hell Mustang . Thought that was pretty neat.

Got moonshine back in the healing room, and pulled the D300. This will be the last time pulling a transfercase without a jack Yeah, the 205 setup is just a little bit larger.

Pulled the ecobox apart to put in the new input gear.

New one on the left foreground, old one on the right. The bearing journal is much wider on the old one. The NP241s (guts of the ecobox) came with 16mm and 24mm wide input bearings. I was told this one had the 16mm, and ordered the input shaft accordingly. In fact, it has a 24mm input bearing. Hoping that powerdrivendiesel will allow me to exchange the shaft I got for the one I need.

Not a big deal. Will get it sorted, then put back together. This is what the new input shaft will look like inside the planetary gearset.

Sorry about that John, my notes (and part #'s) were for the 16mm. I'm not sure how in the world I got that wrong.
It's a heavy setup and I found that it was a lot easier to place the ecobox, then put the 205 in place. I'd lift both in by hand, otherwise I couldn't get the 205 to line up with the ecobox.

 

[GLTHFJ60]

It's all good Darrel! Power Driven Diesel is allowing me to exchange the input gear I bought, so no harm, no foul.

You were able to lift the 205 by hand into position? I couldn't even lift it off the bed of my flatbed

I'm happy they were cool with the exchange.

The 205 is a heavy bastard, but I only frustrated myself trying to jack it into place. Press it up, align the studs, and shove it on worked best for me.

Leave some for the rest of us!

Yeah, but you are a beast. I couldn't do that either... LOL!

For documentation purposes. Aired up all tires to 8psi and started measuring angles with my new harbor freight angle gauge.

1* lean to the passenger side according to the core support:

Engine has a 4.5* perpendicular lean sloping down towards the passenger side:

Truck is .8* squat according to the door (in hindsight, probably not the best reference)

Engine has a .6* squat, so the engine is dead flat in the chassis, or maybe tilted a hair down towards the front. This is good, because it will allow me to tilt the engine down towards the rear ~5* or so to make my rear driveline angle happy.

Got the new shaft in on Friday late as well. Fits up as expected. Torn on whether or not to pull the transmission to clean it and inspect, or just drop the transmission crossmember so I can drop the engine, to be able to continue mock up.

Also, my buddy @Fort Knox started a thread about before and after. This is a pic from CMCC 2008, then a pic from GSMTR 2018. CMCC 2008 was my first real camping and wheeling trip. She's come a long way since then. It's cool to reflect every once in a while.

The problem with tilting the motor down is what it does to the front transfer output angle. You’re planning on running a regular (non-DC) front driveshaft right? What’s max operating angle on that? Loosing 5 degrees there is a lot.

I’d pull the transmission and get the tailhousing off and check your 5th gear. You’ve been running it for while.

DC driveshafts front and rear. Not sure if I'll land at 5* or not, just spitballing. It will all depend on the rear driveline angle.

Good call on checking 5th gear.

Is there an issue with your rear driveshaft angle now? Or do you want to make the rear less steep because it will be getting shorter?
Might be some merit to that for high speeds.
