SCORE! The cruzah will crawl!

[Eskimo]

Traded my 465/205 combo to a guy for a 700R4, fresh from a good tranny shop, low-stall TC, AA 700R4 to Toyota t-case, and a toyota t-case with 4.7 gears... Oh, and a few little "accessories"... nothing big, just a big stacked plate tranny cooler with built-in fan, and an Art Carr shifter!!!! We also traded driveshafts, and I got a minitruck CV shaft for the rear (needs to be shortened), and another minitruck CV end for possible use with the front shaft. He REALLY wanted a manual tranny..

BudBuilt will be working up a Crossmember/skid for this setup if I don't think of anything easy...

The 700R4/adapter/minitruck case combo is 1.5" longer than my old setup.

The only issue is the front d-shaft to the tranny pan. We were going to clock the t-case, but it's better to leave it low, and just cut the floorboard where it hits. Might run the slip-spline section at the t-case end, and that should take care of clearance issues.

Anyone BTDT with a setup like this?

Sounds mighty sweet. You might have to look into upgrading your brakes to top notch components to be able to hold 'er in place.

If you run the slip shaft on the tcase end you might as well forget runnign a front CV..

Crossmember/skid is simple. The mini tcase had a nice mount on the bottom of it and I believe that the adapter does too.

Still trying to figure out what you mean by clocking the tranny will allow it not to hit the tranny pan. Do you want to clock it down?? Clocking it up typically causes more problems.

Additionally, upgrade the front input to 23 spline. Call Marlin and see if he has the 23 spline, total spline inputs yet.

Why is that?

No mount on the adapter, unfortunately... But I don't think it will be too tough to fab one that uses the lower 2 of the 4 bolts that bolt the adapter to the t-case, if necessary.

Sometimes, like with my friend's 700R4/Dana 300 that he clocked it flat, it brought the front output of the t-case further outwards as well as up, and he didn't have any more issues with the pan, but he did when it was in the stock position. Unfortunately, the toy case's output isn't that far away from centerline for this to work.

Additionally, upgrade the front input to 23 spline. Call Marlin and see if he has the 23 spline, total spline inputs yet.

Very good idea, and I checked into this. Unfortunately, Marlin's 4.7 input gear won't work with an AA gearset. Using AA's 23 spline, 4.7 input ($200) and then a 27/23 spline coupler ($250) will work, but that's alot of bank, and at that point, it would be better to run an entire Marlin case with the total spline input, or use Marlin's Toybox adapter...

Gumby - If I wind up going to propane as part of this conversion, I may add a power brake booster, but I don't like power brakes and a carb... I've had to dead-stick back down too many hills before, where I needed to have brakes... My junk already has 4-wheel discs, so hopefully a power booster and properly sized M/C will work well.

The front output of a tcase is horizontal. If you have turned the pinion up to point at the tcase you need a CV (sort of) If you put the slip end on the Tcase end it will point straight ahead. Aand the CV will be at the no angle end. No good. A CV Driveshaft is designed to run most of the angle at the CV end. Not the U joint end.

 

[Eskimo]

Haha, I think you've got my intentions confused, but now I see where you're coming from.

My plans is, looking from back to front:

t-case front output flange
double-cardan (CV) joint
slip-yoke section of shaft (std. high angle 12")
.188 or .250 wall tubing
standard Toyota LC u-joint
FJ diff flange

Basically, it's like a normal CV shaft, excepot when it gets made, I'll have the slip-spline put up at the t-case end, since it's a much smaller diameter than the rest of the driveshaft...

I am NOT simply going to take a stock CV driveshaft and flip it around...

 

[Mace]

I kinda thought that was waht you were thinking.
Talk to Jess about it. For some reason welding the slip shaft to a CV dsounds like a very difficult think to do.

But it might be cool


Honestly, Just run a standard DS if you need the space. You will not know the difference.

That is a sweet score.
If I could just find somebody with that setup that wanted to trade for my SM420/TLC case I'd be set.
