What transfer box is this?

[OZ83]

That's either an sj413 or a later sj410 transfer box, the case is identical to the samurai one and you can remove the drum brake and fit your flanges

If you shift it into 4 low, then count the number of turns of the Input it takes to turn the output once it will give you the ratio and identify which box it is.

2.3ish turns to one is a 413 tbox

2.5 turns to one is a 410 tbox, this is good to fit of you are running larger than stock tyres and will pretty much perfectly correct the gearing for 235/75r15 tyres in high.

Thanks a lot. Today i try but i cant shift... Now i have a damaged axle. So i work on another one to replace the warped one.

But i will try it later again.

Best Regards
