Dual Cases Are In!
Today ended up being a fairly productive half a day in the garage. The duals are in, all electric is hooked back up, shifters are test fitted and they'll work. There's still some things I didn't expect and I'll touch on those later.
I know I give the city folk a lot of crap about clay bars, clean engine bays and trans jacks. I'll be honest here. There is no way in hell I could have redneck engineered a way to get these duals in without a trans jack. I'll give credit where it's due. That thing is awesome. I'm still not washing my truck or engine bay though. lol
Last night I managed to squeeze in some time to do 20 minutes of prep work. That involved RTVing the coupling to the transmission. Installing the tail housing. Then installing the new oil seal coupling.
Here's that coupling I've been waiting on in it's natural place.
Here's the tail housing back in place with the new oil seal coupling. Beating the oil seal coupling into place is kinda nerve racking. If it's not perfectly seated the chance of the duals mating to is are pretty slim.
After last nights prep it was off to the races. The first thing that needed to be done was to lengthen the 3 wires that come off the t-case. When adding duals you add 8 1/2" to the overall length of the drivetrain. I added 12" to each wire just so I didn't have to fight anything later. It's a lot easier to zip tie a bundle of wires in a tight space then re-crimp them.
After pulling the shifters off the duals I placed some cardboard over the shifter openings. The last thing you want is dirt falling into these things.
Now it was time to get that fancy trans jack into action. If you notice on my first go around I'm using the chain that come with the jack and a strap. A lot of folks seem to think that safety chain is shit. I agree. If you look at the final install there's two straps and no chain. The things a joke but that's the only complaint I have about this Torin jack.
One of the big questions of the day I had was would the duals even fit under my rig when they where on the jack. Take note here guys on 32's. It BARELY clears true 33's. lol
This is what the moment of truth looks like.
Right about 5 seconds after that last photo the "safety" chain slipped. I shouldn't say slipped as much as it bent both attachment point. That caused the whole unit to spin but luckily my second strap and my arm stopped what could have been a very shitty end to my day.
After firing off a quick email to Torin that started with "Dear *******s" I got back in the garage. This time I rigged it without the chain. Two 1" nylon webbing straps are a much better and safer way to go for sure. Here's the jack at an extreme angle with those straps. It never moved. If you have an auto there's only one way this thing goes in. This is the way.
If you try and go straight up you'll hit the rear crossmember mount. If you try and go nose down you'll clear the mount but bind on the 23 spline crawlbox input. Doing it this way here's your clearance on the rear crossmember.
Here's what the lower studs on the crawlbox have for clearance in the same position. As you can see it's a really tight fit with an auto.
With some spatial awareness and very small angle and level changes it eventually goes in just about perfect. Here's the proof.
This is after I put the crossmembers back in. It's full supported by the trans mount at this point. I still need to figure out the crawl box mount but I have a pretty solid plan in my mind.
If you guys remember I drilled out the center of the 99 cupholders and did some math so I could clearance the rear twin sticks before the t-case went in. Here's how that turned out.
And here's both shifters test fitted. I'd say it'll work just fine.
This is the sum total of left over parts for the job. Two of those I expected to have left over. One I didn't. TG uses two supplied bolts for the lower adapter plate to tail housing. So the two t-case bolts that you see I knew I'd have as leftovers. The surprise was the drivers side rear cross member inside bolt. There's know way that's going back in. Ever. lol
So the things I didn't expect are not that big of a deal. The first is the crossmember bolt. I'm fine having one instead of two so problem solved. The second is I'm 85% sure my front drive shaft is going to hit the front crossmember. Not by much. If it does I'll just clearance the crossmember a bit. The third is the rear twin sticks. The passenger side stick hits the 99 e-brake dead center. There's a few solutions to this. Bend the stick to clear or use my OG 97 console. I'll look into that more and go with what's easiest, urrrr, I mean best. lol
So that's all there is to dual casing these rigs guys. It may seem like a huge project but I'm less then 12 hours of my time invested so far. That would be closer to 16 if I had built the crawl box myself.
I chose to let Eric at Yotamasters handle that. If anyone ever wants to go that route I highly recommend him and his shop. He built it for not much more than I could have assembled the parts for, And he took care of sourcing everything. Including the crawl box core.
I'd also like to thank Wyatt from Rock Solid Toys. I called him twice during my research for the install. Both times he picked up the phone and answered my questions. That's just a solid thing to do considering I wasn't a customer. I'll be getting my shifter knobs from him as a thank you.
There's also a bunch of guys in the dual case thread that deserve a thanks. I'd have done this anyway but that thread helped me immensely. Most of the info you need is there. Most. The rest isn't that hard to piece together. So to all you guys that posted in this
gem, thank you. And specifically, [MENTION=53470]Rockdawg84[/MENTION] . Once my shafts are made and I'm actually wheeling this thing again I would humbly request a spot on your list. I'll take 14 sine you have at [MENTION=102168]owyheerat[/MENTION] listed twice. lol
I also owe a big debt of gratitude to [MENTION=135317]rkntoy[/MENTION]. He went out of his way to not only source a 99+ center console and all the parts needed to swap it for me but he also shipped it. I owe you one brother. Let's find some deep snow to play in this winter.
So now I sit here waiting for shafts to be made. I'm really looking forward to actually driving this thing through some larger then average rock gardens soon. I'll update when I get the console and shifter thing figured out.
