87pathy Posted September 3, 2009 Share Posted September 3, 2009 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. photo's after the weekend! Link to comment Share on other sites More sharing options...

87pathy Posted September 8, 2009 Author Share Posted September 8, 2009 Well, here it is. started with a wheelable vehicle saturday morning. Out comes the transfer case. another shot a little side by side of the nissan Tx-10 and hte new stak D300 back end of the case opened up 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.

87pathy Posted September 8, 2009 Author Share Posted September 8, 2009 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) gears on the new shaft ready to go. 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.

87pathy Posted September 8, 2009 Author Share Posted September 8, 2009 1 of the shifters is now gone. so remove the spring and bearing, remove the locking Pill, and weld up the rocker. crawler box complete Link to comment Share on other sites More sharing options...
87pathy Posted September 8, 2009 Author Share Posted September 8, 2009 crawler box installed 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 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. Link to comment Share on other sites More sharing options...

87pathy Posted March 3, 2011 Author Share Posted March 3, 2011 unfortuantly no. I have had zero issues. all is good in the hood. It was very stiff shifting, but has gotten better. I have found that for normal trail bopping. just using the 2.6:1 in the stack case works mint. the 2.02 in the stock nissan case was a little high, just a touch lower and sweeet. Its cool, when i get to an opstackle,in the 2.6:1, i reach down pull the 2 speed box in low range, (shifts mint) crawl the front end up, reach down, shift back to high in the 2 speed box.. and PIN IT... soooo nice.. Front digs are sweet too. Here is a vid of the rubicon in august.. don't remember what gear i was in, buy you can seee its pretty low. Link to comment Share on other sites More sharing options...
