5.13 gears?

[cowazuki]

Hey everyone, I'm getting ready to do the gear swap. I've got two sets of gears out of the front of a sidekick (5.13's) now I want to know what's involved in the rear set up..........Keep in mind that I'm putting a Lockrite in the rear.........Do I need the spacer's or not? what about the sami axles.....are they the same size? For the front I was told that it was a complete bolt on for the whole centre section.............Is that right? If anyone know's out there, please help me out.............Thanx.:(

for the front, do not use the aluminum carrier... it is weaker... transfer it to the samurai one. Same for the rear.

for the front and rear, you need a Cofee Can, the same size as the carrier to hold the Pins in. Slide it over top. (or you can purchase the kit from Breeze or other offroad places)

As for the spacer, I have not used one, and everything is fine. I have been told you need one, and then other people say you don't... Who knows, there are different tolerances in the castings it seems...

Also, I have had to dent the indented portion of the axletube pumpkin housing to fit the ring gear without rubbing. Everyone says you don't need to do that, but I had to. Shadow (Al Graham) had to do the same as well, so it could be that there are differences in the housings... BTW, he used the spacer as far as I know... Also, Al may have done a write up on the swap as well...

I do have some pictures of what it looks like apart etc... If you need some more info, let me know..

[cowazuki]

Thanks so much for the detailed info................where can I find that write up?:(

As for the front case I don't realy do alot of rock crawling so would it matter if it was the alum case or not?:yike

[Depot]

I blew up my front case in the snow of all places... just spinning the hell outta the tires, didnt hook up on nutin. the aluminum flexes a bit too much and just snaps in half ruining an otherwise good set of gears...


go steel.. its worth the work

close super zuk...i thought i had a write up also on the gear swap but it was the 4:16 t-case swap i found that was posted..

when i did my 5:13 swap i removed the ring gear and the pinion out of the tracker pods and put the 2 of them in the zuk pods. i did use the "can" ( i used metal formed it around and tacked it together and its still removable) on the front set when i put them in to hold the locker pins in place. in the rear i didn't because of everything being welded together.

as far as the ring spacer goes i did use them. is there a difference. beats me i've never heard of anyone blowing up a rear end because they didn't have it in there.

[Depot]

where does that spacer ring go for the 513's? Am I correct in thinking that it goes behing the ring gear so as to space it out a tad so that u dont have to adjust ur side bearing quite so far over? if that is the case, then its purpose is to spread the load of the side bearings evenly throughout the carrier if u can adjust em up without the spacer?

just curious

That's pretty much it Shadow...
Was I right in saying you had to dent your pumpkin out too?

Just wondering if anyone else had that experience???

Cowazuki, the only real way to see what we're talking about is to tear one apart. The only "difficult" part of the job is setting the lash, I have a diagaram of how it is supposed to look when finished, and what way you need to adjust everything when it is in too far, or out too far...

As for direct instructions, well, I haven't done it in 3 years, so... better looking on offroad.com (I was sure shadow had an article on it)
as soon as I find them, I'll post a link here...
Cowazuki, if you have specific questions when you are doing it, feel free to ask, I am sure I can answer that way, but my memory of the job point for point is kind of weak.
Just a note though, there are many people on this site that have done this conversion, so your questions will be quickly answered.

I've done a few 5.13 gear swaps and found that the ring gear spacer is needed because the thickness of the ring gear is thinner on the tracker than the samurai. If you don't, you will probably bottom out on the threads on the carrier bearing adjuster on one side. Keep in mind that casting differs and that is why some people don't need it and some people do. I have tried the actual ring gear spacer and did not like it. The reason is because the stock ring gear centers itself by the inner diameter to the outside diameter of the differential carrier. With the ring gear spacer in place, the ring gear is now centered by the bolts. I remember a few times, I have to clocking the ring gear about 8 times to find the right best spot, so that my backlash is even on all three points that I measured.
Spidertrax have a spacer that I think is better. It is actually a spacer for one carrier bearing cup. That allows the ring gear to be mounted properly onto the diff carrier, and also allow the carrier bearing adjuster to be threaded properly without bottoming out. I think any machine shop will be able to rig up a spacer like without too much problem.
As for the coffee can, I have used them. As for putting a dent on the pumpkin, I did on mine, but not on another one. Guess it all depends on the casting as well as the axle tolerance.

Cowazuki, the setup is not too hard to do. Just make sure everything is kept very clean. The Zuk(also toyota) gears are very easy to do since you can put the carrier in the vice and do all your setups there instead of crawling underneath the truck to do them. Just think doing gears in your heated basement instead of on the cold garage floor when it is winter!
Talk to Zukin or SJKrawler, they both have done these not too long ago. Good luck!:D

yes i had to dent my pumpkin also......as far as the spacer go and someone needs one i have access to a place with a lazer cutter and they have a template to make more...i think there about 25-30$

Interesting......... I think what Jimny1000 is implying about the ring gear spacer is that the shear factor of the ring gear bolts increases. Makes sense. Ive used both, side gear spacer and ring gear spacer. Currently Im using a ring gear spacer. Seems to be fine. I went this route cuz I personally would believe, like Depot said, the side bearing spacer would increase the load and run the bearings down a lil quicker. Thats just an opinion as I dont know for sure ( I just drive the shit out of it regardless of setup). Im still running the aluminum carrier up front cuz Im a lazy bastard. Biggest problem I find in the aluminum housing is that the pinion bearing goes quickly cuz there is no oil galley going to the front bearing so we have a slight oil starvation problem there. Like Jimny said, keep everything CLEAN and DONT mismatch the bearing caps and that kinda shit :beer:

Hey Guys,

Thanks for all of your input............it's gonna be a big help. I think i'm ready to takle it.

P.S. Shadow, I'll take you up on that offer for the spacers. Just PM me..:eek:


Thanx again guys:beer:

[cowazuki]

Well guys I'm done........I did it.......whoo hoo. Ya, it wasn't that hard after all. Thanks for all of your help guys......I realy apreciate it...............Whoo hoo:beer:

[gordZuki]

did u guys make the spacers or buy them?? and if u bought them did u copy them??

[Shadow]

a friend of mine got ahold of one from someplace....we then got a couple made. i presently don't have a stock of them but i can get the company to cut more with their laser cutter.

i would think the place would like to do more than just 1. if i get enough people wanting them i'll put in an order. PM me and we'll go from there..

Hey Guys, Sorry I didn't make any doubles of the spacers. I bought them from Breeze industries out in BC. The kit cost $86.00 per diff. They were a complete bolt on.

I just wanted to ask anyone if they have ever ran into this problem. We set up the rear end with the Sami case, Sidekick 5.13 gears, Breeze spacer and ring and a Lockrite locker......The problem we ran into was that the pinion teeth don't go down far enough onto the ring gear......Do I have to shim behind the bearing or not? Has anyone ever ran into this problem? Is it just ok without the shim?

P.S. Does anyone have the proper spec's for the caps and the pinion flange nut?

Please let me know as soon as possible.................Thanx.
