Well, Last weekend i failed a rear axle bearing.
so this weekend instead of going wheeling (new curries 9" shafts are going on order next week!) I decided i need to get this done for the anual february wheeling / camping trip.

specs are
Nissan TBI V6 with lots of miles
Stock nissan 5 speed.
Stock nissan TX -10 with 3.7:1 low range (turned into a reduction box)
Stak Dana 300 drivers drop with stock 2.62:1 gears. (twin stick of course)

Overall crawl ratios will be as show below.

that main shaft was a MOTHER fucker to get apart.

I ended up destroying the aft housing of the nissan case.

the crawler gears were not designed to go with this crawlwer box..

it's goinna work, but MOHTER F-ER

I didn't have a proper press to get the main shaft componenets off, so a splitting maul and cinder blocks worked well.. sorry no picks of hammering.

but look at the size of the nissan stuff.

One of the things i had to do was use this big bearing for the main output of the crawler box. It had a oil retaining seal built into it. This was to keep oil IN the back half of the transfer case. But with the new arangement, it would have Kept oil OUT of the bearing.. so i pulled out the seal and ran it without. (it was only on 1 side of the bearing)

i had to improvise a bit as this was designed for stock gears and the 3.7:1 gears covered the aft mounting holes.
No big deal, i pulled the shaft back out, installed the "adaptor?" put the shaft back in, put hte retaining clip in THROUGH the adaptor, and then pressed the seal back in.

1 of the shifters is now gone.
so remove the spring and bearing, remove the locking Pill, and weld up the rocker.

and Stak installed

here is the really cool part.
my old driveshaft, Minus the 1330 flange (just removed the flange to run a straght YOKE (changed the caps, as the 1330S is 1 1/16" cap at the closed yoke end and 1 1/8" at the "YOKE" end.
so it saved me lots of money.. no new rear drive shaft or retubing necessary
http://i46.photobucket.com/albums/f138/87pathy/DSCF0652.jpg

started on the shifters. I could not find any brake yokes that were short or corse thread, so i bought each of these and cut htem down, and re-threaded the end from 7/16 unf to 1/2" unc. (very little space and just enough to work)
LIKE A GLOVE.

all in all it has taken me about 22 hours of work to get to this point.

enjoy.

it was 22 to get where i'm at now. all by myself.

would have been easier if i had a spare hand and a press.

the hardest part was getting the main shaft out of hte transfer case.
I had to destroy the old tail housing to get the gear and bearing out.

no biggy as it was scrap anyway.. just pissed me off

Looks wicked man, best o' luck shifter wise! Does this mean you have a TX-10 SYE you're looking to get rid of? If so I'm looking for one.
