Looking good. <img src="/forums/images/graemlins/kewl.gif" alt="" /> So you are running a Gen1 3.0 in that?
BTW, the pulse sensor is for Gen2+ transmission. Nothing to do with the speedo.
Thanks Nathan! like Johnny said its got a 8v 2.4L. What does the pulse sensor actually do? I thought it was something that worked with the speed sensor? I'll have to re read your write up again. This Montero is a 1995 (DEC '94) but it came with a 12V 3.0, So it has a AW2 trans with a odd 6 bolt pattern. The NP231 still lined up on 5 holes on the tailhousing adapter though.
Toasty, more on the the 231 swap in please. I was thinking of putting one in my 91 LWB....Should I get the tail-housing off a 92/93 Trans? or will the 231 bolt to the gen 1 auto tail-housing as is? How did you work out the drive shaft? I was thinking going 231 with SYE with a mechanical speedo hookup for the gen 1 speedo...TIA
The 231 will mate to a gen 1 perfectly, but if your '91 ends up like my truggy and one hole is off don't worry about that too much it's easy to drill or forget about (i just left mine 5 bolt). If you have the odd style like me you will have to drive out the dowel pin too. The case you need will be a short shaft NP231 (Mated to an AX-15) you can get the long shaft but you'll need to have it cut down.
The drive shafts i made myself, the front drive shaft i used was a cherokee front double cardian setup with the u-joint end switched to the montero U-joint to the diff. For the rear i wanted something heavier since it takes more abuse on hill climbs and stuff pluss it has to travel with the axle where the front doesn't. I used the standard Gen 2 V6 shaft with F-350 slip joint, I have the yoke for the 9.5" SR pinion flange on the bottom and the 9" pinion flange on the t-case side. Drive shafts are really easy to DIY i found out, just have to know what you're doing. I also made my own SYE, mine turned out fine but i don't recommend doing it because you need a special kind of welding wire + pre-heat/post heat garbage. Also the wire costs more than an SYE kit so if you don't already have it it's definately not worth doing.
If you want you can call me this weekend and i can tell you what you need to make your own drive shafts.
