231 Box 4 Rocks Build Thread (for dumbasses)

[pipehitter155]

After a month or so of research and trying to figure out how to put this fuckin thing together i decided to put a thread together showing a detailed way of putting the Box 4 Rocks kit together. Believe it or not it's actually quite simple. Don't for those dumbasses who can't read I've got plenty of pictures (i bet TJP is bout SHITTING HIT PANTS RIGHT NOW!!! : Anyway, here goes:

Parts included in the kit:

Backing plate and clocking ring bolts

231 to D300 shaft (23 spline in my case)

new 231 guide rod for shift fork

D300 clocking ring
1"x4" (i believe the measurements are correct) piece of aluminum used for blocking off the portion of the case after cutting off unuseable end.

not included:
Dana 300

NP 231 Front half

Tools needed:
Misc sockets and allen wrenches
RTV
loc-tite

Alright:
You only want to keep the pieces of the NP231 you see in this picture, nothing more nothing less--makes sure you have the pads....despite what the stealership has in their parts records they have differents pads for differents year shifter forks so not all 231's are the same (TRUST ME I KNOW)


**DISREGARD SHAFT AND GUIDE ROD--they come w/ the kit

With only front half of 231 case left bolt 'b4r' backing plate on; draw line with marking tool:



Weld block into case ONLY!!! here's a picture of a case i found on pirate:



after block has been welded to 231 case to reassemble parts like the picture shown:

[pipehitter155]

Next attach D300 clocking ring to D300 t-case using loc-tite and RTV



Next I made a sight tube on my 'b4r' backing plate like this:
using two of these:

and some tube i took the top screw and the bottom brass allen screw out and replaced like so:


This is probably where you probably where you wanna put the 231 on the vehicle and then the D300 (at least that's what i'm gonna do). I would also maybe mock it up outside the vehicle a few times and mark the backing plate and the clocking ring to save some time since that D300 is pretty damn heavy.

Now attach the backing plate to the clocking of the D300 using the bolts provided in the kit like so using lots of RTV:



Then attach D300 to 231 no forgetting shift fork/guide rod spring for the 231 case using the bolts provided it should look something like this; remember RTV is your friend cause leaks 2 weeks later really suck balls:



or about a thousand different ways depending on how it's clocked.

Please feel free to add pictures and info for those who have already done this; this is not the all inclusive thread but i'm sure it will help a few out.

Sweet just what I needed!!

Thanks.

Nice build, just curious about how much time you spent?

[pipehitter155]

spent putting it together, not really long at all....research awhile, i don't think the install will be to bad....the shifters are gonna be bad i think....

[Dookey]

I take it you found the correct pads??

[Bastardized]

Damn Eric the shit missle isnt going to go anywhere with all that gearing......... I like it tho!!!!!!!!!!!! Can not wait until its done........ Going to put all other Cherokees to shame around here thats for sure!!!!!!!!!!!!!!!!!

Nice.. cant wait to see it all mocked up .... I guess I need to get motivated and start putting together my shit now

[pipehitter155]

I learned this the hard way yesterday:

the input shaft on a 04 TJ 231 (5 spd i'm sure) is longer than that of 99 XJ 231 input shaft. Glad i live really close to a machine shop....bear in mind not all 231's are the same!!!

Tech to the top BS to the bottom...

clean up

[duffxj]

are you running a pass drop 60. does the box for rocks kit allow the 300 to be clocked drivers drop or do i have to drop the $ for a flip kit as well. i have seen the shifter flip for the 300 but am not sure how well it works i would like to run the same setup but need it drivers drop. any help is appriciated

KEEP US POSTED ON THE SHIT MISSILE, props on the build

[pipehitter155]

i just flippin it on the cheap w/ the kit from duffy w/ the shifters that he made....i really haven't figured out how people put an extra seal in the shift rails...i figured i would throw a little RTV around them and call it good if they start leaking at all....we'll see....i'm run a ford hp60

Since you labeled it as for Dumb Arses, I'll ask a dumb arse (or inexperienced ) question: What are the "pads" you are talking about? I've never taken a T-case apart (yet). Got a pic of them by any chance? I am a better visual learner anyhoo! Thanks in advance, feel free to flame away.

Ah, ok. The little ones on the shift fork around the collar of the main shaft. Gotcha. Wouldn't have noticed that that they were separate or translucent without being pointed out from that picture. Thanks!

Do you have any shifter pics of the cases in the XJ?

I bought this kit used from a guy off of Pirate that attaches a 231 to a 300. But i cant decide if i want to run a chevy 60 or a ford 60.

[roczuk]

updates?

[pipehitter155]

I just drilled the tranny about a week ago, and i'm currently working on the tunnel cover for it, then onto the crossmember for the D300 when all that is done it should be good to go...

Yeah, that makes two of us.



I decided to start over on mine, it wasn't worth fucking around with making little patch panels and shit.

I run a Dodge 60 which is basically the same as a chevy. This is how it shifts.



You can also see why I decided to go to plan B, as shown at the top of this post.

I can see your XJ looking a lot like ASHMAN'S in the future!

Well, I'll be framing out a new tunnel around everything and having removable skins on it. It'll look a lot more finished once everything is painted etc.

I've still got much more body that Ashman has, I guess it'll just be a matter of time before it goes away though. I'd like to keep it together as long as possible though.



Doors still go on, A/C blows nice & cold, and the stereo's pretty damn good too.

i got duffys cheap flip shifters , and they come out pretty much where the stock tc shifter comes out , just needed to cut back about two inches as the shifters have lots of throw. Also need to bend them abit to clear my seat but seems to work well. You guys have any sealing problems I thought i used plenty of rtv but still got a slight leak around the clocking ring.

Yeah, I have a small one at the same spot. I only applied RTV to one side of the clocking ring though (between the ring and the NP231 adapter plate). Next time I take it apart I'm going to put some stuff on both sides of the clocking ring.

I also recommend putting some sort of sight tube on it so you can keep an eye on the fluid level; you can sorta see mine in the pic above. I can get the part numbers for the fittings and stuff I used if needed.
