Thanks, in that case, I'm very familiar with many of his threads.


I just stumbled upon this article on the V5MT1 I've never seen referenced, despite doing some considerable research.

http://tcase.rsgear.com/articles/1997_06.pdf

After reading, it seems to jive with everything I've heard/read about the V5MT1 except for the mention that GL-5 fluid is ok to use.

I've read several posts directly contradicting that, stating GL-4 is the only fluid that should ever be put in a V5MT1, GL-5 should NEVER be used.

Maybe it'll prove valuable to someone else too. I've attached it here as a PDF in case the link dies.

On the left is beauty. On the right is a KM-145.

Surrounding these is my junk pile.

Slight correction: The one on the right is part of your junk pile. Just my opinion, of course. I don't like the KM-145 for longevity.

Same is true of the KM-145, for that matter, but I think that was already pretty well known.

In searching for a donor parts truck to harvest from, I've come across an AWD MS listed as a 2002 with a 3.0(6G72) and 4.9 gears.



I haven't been able to check out the truck for myself yet and the seller seems to be a bit naive regarding it's specifics/specs...

I'm far from an expert but I thought most post '99 MSs with AWD/4WD were 3.5 6G74s???

With the 3.0, will the rear diff still be a 9" or is it likely to be a 9.5"?

I'm 99% certain that despite being a 3.0, it wont have the leaf spring rear I'm after, correct?

I've no use for 4.9 gears with my intended build, however, it seems there's no shortage of people in search of them....

So my questions are, what are a set of F & R diffs with 4.9's worth?

I'm wondering if selling them would justify the hassle of pulling them when/if I harvest:

-Complete brakes
-Front suspension
-Complete steering assembly

Any reason the above parts wouldn't fit my '87 D50?

Is there anything else I should grab if the guy decides to part it out?

 We Montero guys typically just want the AWD 4.90 front axle assembly, they can be had for around $200. That rear is likely 9" and definitely coil sprung.

 I don't do a lot of Mighty Max stuff but that's the suspension and steering i would run, it will require work though.

Had a fruitful trip to the junk yard this weekend to harvest a few parts from a '94 MM 3.0/5MT in hopes they'll make swapping most of the running gear from a '97-'99 MS to my truck's frame easier.



I nabbed....

-Transmission cross member and mount / I'm hoping this will make fitting the V5MT1 5MT from the MS to my truck's frame a non, or at least minimal, issue.

-Front diff cross member / I'm hoping this will make fitting the 8" front diff from the MS to my truck's frame a non, or at least minimal, issue.

-Front drive shaft / I'm hoping this will be the proper length between the 8" front diff and transfer case from the MS when fitted into my truck.

-Hydraulic clutch and brake pedal assembly / The D4BF uses a hydraulic clutch while my truck runs a cable via a one piece brake/clutch pedal assembly.

I'm not certain yet if any of these parts will be required or not but my research indicates one or many might be invaluable and later model MM/D50s w/ the 3.0/5MT combo don't pop up too often so I figured it was worth the trip/gamble.

Plus, I also scored a set of Aisin manual locking hubs; that alone warranted the trip.

I'm also leaning toward buying a complete '97 MS 3.0/5MT out of another junkyard to harvest most of what I want/need; 5mt transmission/transfer case/compete rear end/steering/brakes/front suspension/parking brake/etc.



Its looking like I should be able to get it hauled home for about $700, and short of a locking rear diff, it has nearly everything I'm looking for. Pulling everything separately will end up costing nearly twice as much and increases the odds of some obscure incompatibility.

It has 4.272 gears which I think I'll run for a bit to see how it drives. I've been playing with a gearing/RPM calculator in addition to reaching out to several others who have done this swap to see what gears will give me the best performance/cruising RPM compromise, and I'm still undecided...

We'll see how the 4.272s do with 235/85r16 tires but my gut tells me I'll end up swapping in 4.63 gears along with an ARB rear locker/compressor.

The lack of serviceability and availability of replacement diaphragms for the OEM locker, along with my desire to have a compressor I can potentially air up with, and possibly run a front locker as well, are making the ARB units pretty attractive...

Hoping to drag home the MS parts truck by the end of the month and order the D4BF motor by the end of Sept; fingers crossed.

PLH:

Thanks, your numerous posts have been immensely informative; I anticipate having more than a few questions for you once I actually dive into this project....


Nothing too exciting to report, the funds I've been planning to use for this project were delayed for about a month, putting things on hold; they should be freed up later this month, enabling me to move ahead.

I was able to take advantage of the 40% sale at the semi local pick-n-pull yard over the weekend, scoring a non cracked dash I've been searching for in the same blue as my interior, a replacement front passenger turn signal, and 2x windshield wiper arms from a Volvo 740 for a grand total of $32, which I was pretty satisfied with.

I had seen Volvo windshield wiper arms mentioned as a simple bolt on upgrade with far more common/standard 'J' style blade mounts over on mightyram50, http://www.mightyram50.net/vbulletin/showthread.php/6425-Volvo-240-windshield-wiper-arms

Happy to report the info was accurate, they're a near perfect match; the set I pulled were from a Volvo 740 I believe.

Hoping to order my D4BF motor by the end of the month and praying S Korea isn't slapped with some obscene tariff before I can get it landed stateside.

I'm wondering if any of you can help me in tracking down a set of wheels... I'm hoping to find 'NATO' style steel rims in 16"x7" / 6x139.7mm / 108mm center bore with workable backspacing.

I incorrectly presumed there would be plenty of likely OEM choices from other vehicles fitting those specs but am coming up pretty dry....

As of now, the leading candidates are:

These Montero steel rims that check all my boxes, but at $95/ea, $475+shipping for the 5 I want, seems stupid high for such basic rims....

https://www.finishlinewheels.com/MITSUBISHI/MONTERO/2002/S-65787U20/

These Toyota steel rims look promising, are pretty affordable at $55/ea, $275 shipped for 5, but having the centers bored from 106mm to 108mm adds to the cost and I'm not certain the center bores would be conducive to a machinist's boring bar due to the fact that they're stamped. Being lugcentric, tt shouldn't really matter though.... Can anyone confirm?

https://www.wheelsandcaps.com/Toyota-Tacoma-2013_p-52618-steel-wheel-rim-16x7-69482.aspx?variantid=258792&ref=g-pla&gclid=CjwKCAjwo_HdBRBjEiwAiPPXpHGYDIqsHKs-EaYO-6tmPIqZ4SCZVu6QuPZvbdB2gLQI24BmZsx44hoCJ1MQAvD_BwE

The only other semi viable choice I've come across would be these stock Toyota Tacoma alloy rims. They're the only alloy rims I've found with aesthetics I like, they can be found pretty cheap on CL, but having the centers bored from 106mm to 108mm adds to the cost before bead/sand blasting/painting them.


This however is all academic/research at this point as I'm not certain what backspacing I'll want after swapping in the wider MS rear axle and front suspension/steering as well as what front fender well clearances I'll need to contend with after the modest +/-2" lift I'm hoping to gain from the UCAs/HD Torsion bars and 235/85r16 tires.

Any educated insights/advice is appreciated.

PLH:

I'm sure many of the 16" Montero rims would work but I haven't seen any I like the looks of. At this point the need for rims/tires is still pretty far off so I can afford to be vain, plus I'm still not certain what sort of back spacing/spacers I may need to account for the wider, +/-2"??, MS rear axle and MS front end.

RXIN:

I'm happy to hear that, I had hoped/suspected the Toyota 106mm vs Mitsu 108mm center holes might be negligible on certain rims since they're both lug centric; fingers crossed I can find a set of rims that'll just fit.


In other news I've had some success in tracking down a few of the more difficult to find parts I'm after.

The MM/D50 speedo/tach gauge cluster I located arrived late last week and looks to be in great shape.

I was able to find a junk yard 375 miles away with a '97 & '99 MS so rented a minivan from budget at 9pm Thurs night, drove till 2:15am, crashed for a few hours in a Walmart parking lot half a mile from the yard, pulled a transmission/transfer case and rear axle, had it all loaded up and back on the road by 2:30pm, made it home by 8:30pm, and dropped the rental van off at 8:45pm Fri night.

For my efforts I ended up with a V5MT1 5 speed w/transfer case out of a '97 MS that appears to be in good condition, but the total miles on the truck it came out of are unknown...

As well as a fairly complete 4.636 locking rear axle from a '99 MS w/a 3.5.

I haven't had a chance to tear it down and inspect it but am a little bit hesitant as the truck I pulled it from looked pretty beat upon; extra long and flimsy looking rear shackles, rough DIY sliders crudely welded straight to the frame, no sway bars, lots of 'Hey look at me! I'm a gnarly off road rock crawler guy' stickers plastered all over, etc.

I grabbed it anyway as they're not so easy to find and the price was right. It came with calipers, brake lines, parking brakes, the locker compressor and 'r/d lock' switch; unfortunately I was running out of time at the yard and failed to grab the locker ECU and its about 5 hours away.

As it came from a truck w/a 3.5, will this be a 9.5" diff? I've read that 3.0=9" and 3.5=9.5" but have also read that all MS w/leaf rear ends are 9"?

I haven't yet had the opportunity to pull the hubs and measure the axles and count the splines to determine; hopefully be able to later this week.

It also has the ABS sensors, as I won't be running ABS, can I simply pull or clip them flush or is there a reason to source a non ABS rear housing to swap everything into?

I also have a lead on another complete 4.636 locking rear axle from a '99 MS w/a 3.5 as well as an additional V5MT1 w/transfer case out of a '97 MS and will likely grab both if I can just to have a spare of each and/or for parts.

Working to solidify my D4BF order, hopefully this week, the supplier I'm working with is insisting on a wire transfer and I'm pretty reluctant to blindly send several thousand dollars to a vendor I've never dealt with half way across the world.

They seem reputable but their reluctance to accept paypal, escrow.com, payoneer escrow, or other similar services offering some degree of protection/assurances, despite my offers to cover all the associated fees, is concerning and may ultimately derail the purchase.

I'll post greater info/details about my experience buying a D4BF crate motor straight from S Korea if/when I've made my purchase and have concrete figures/advise/prices/experiences to report.
