3.4 v6 adapter plates to gear driven mini truck Tcase

[Booger Weldz]

these adapters are clockable? anyone using one, how far can you tuck(clock) it without a boduy lift and no undercarriage trimming?

If i were you i would run marlins adaptor. I have the older style R150 and i'm wondering if i can run the clocked version on the older modle? I also never saw a price for the marlin one. Maybe i just missed it

[Booger Weldz]

its $349, i have the standard 3.0/r150f adapter i accidentally ordered, i need to switch it out for the 3.4...

[toyin]

So there is a difference from a 3.0/R150 and a 3.4/R150? Curious why they don't make a clocked adapter fort the older serious.?.

I commented in your other post you made asking about what was needed to do the swap but anyways mines only clocked 10* and the floor isnt cut at all and the drain plus is less than 3/4" below the frame rails. Check out my buildup on the marlin board its called something like 96 tacoma.. time for links

ill have to look for your build, i like your truck it sits pretty low too.

Marlins clocks clockwise, Inchworms goes counter clock wise. For the gear case, youd want the counter clockwise clock.

[ErikB]

Yes, from what I've gathered so far, Marlin's is drilled for stock or 10* clocked the *wrong* way for a gear-driven case (what you and I are using), but Inchworm's "goes both ways."

This thread has a bunch of pics of Inchworm's adapter
http://www.pirate4x4.com/forum/showt...light=inchworm
but I don't exactly understand how it works. Looks like it might be 2 plates bolted together? I don't see how it has "clocking from -10 to 45 degrees in 5 degree increments" like the site says, but maybe that is in combo with the second adapter in their taco (driver's side output) setup...? I'm going to try to call Jim this morning.

[ErikB]

FAWK! Just spent 20 minutes on the phone w/ someone at MC trying to explain what we're doing and he kept having to put me on hold and ask someone else questions and get back to me. I did get through on my first try though...

Anyway, their adapter only clocks clockwise (looking from the rear), as Brian mentioned.

The one new bit of info that I hadn't thought about that I gleaned from the call was about shifters-

1) we can use our top-shift cases as-is and somehow block off the factory forward shifter in the tranny (not sure how since I thought the tranny and t-case shifter were part of the same plate?), which requires bringing two new holes up into the body for t-case shifters, or

2) we can change the shift rod in the front case to use the factory forward t-case shifter in the tranny that we already have (cleaner), and block off the now un-used shifter hole in the front t-case.

UPDATE: NOT TRUE!
The V6 t-cases are top shift, so no need to go swapping any shift rods! See my correction a few posts down.


34-4GT-R10 (3.4L - 4cyl Gear-driven T-case - 10* rotation option)

(picture is a front view, so the t-case is rotated clockwise from the rear view)

[ErikB]

Ok, Jim called me back and gave me the low-down on the Inchworm V6 adapters...

The 3.4L and 3.0L adapters are NOT the same because the tranny tailhousings have different bolt patterns.
(I think the exception would be the T100 3.4L because it used the older style pass. side output chain-case)



The inchworm adapter is clockable clockwise when viewed from the rear (for driver's side output) either 15 degrees or 5 degrees (Jim referred to these as -5 and -15).

Its also clockable +10 degrees counter clockwise (for pass. side output).

Clocking past +10 or -15 is done in combo with the dual case adapter further down the line.


The way the Inchworm V6 adapter works is this:

There are 2 bolt patterns for the tranny/adapter interface and 2 bolt patterns for the adapter/t-case interface.

The choices for the tranny/adapter interface are 0* and -15*. The choices for the adapter/t-case interface are 0* or +10. So to get -5*, you use both the +10 and -15 optional patterns.

The pics in Pantydropper's thread I linked above are for a 3.0 adapter, and it appears the only option is to clock it 0* or 10*, no bolt holes for the tranny to clock it -5 or -15.


So for pass. side output we have options of 0, 10, or 20* (if using a clocked dual case adapter).

Jim pointed out that clocking much past 10* doesn't do you much good on a gear-driven case because the bottom/middle of the t-case is still the lowest point. However, clocking further does help if your belly pan is V-shaped (boat sided), and it does get the front driveline up higher outta the rocks.


Also- Jim makes an adapter to bolt your old Taco/3rd gen VSS to the gear-driven cases, however it sounds like it costs more than Marlin's VSS. Dunno if there is a reason beyond price to go one way or the other.
The speedo drive gear ratio may or may not be the same as the drive gear ratio in the new/old t-cases, so your speedo may be off as well. This can be corrected by playing with different ratios, or using a VSS signal converter that corrects the speed. Jim mentioned the Dakota Digital unit, and I found a writeup on it:
http://www.4x4wire.com/toyota/tech/tacoma_speedometer/
http://www.dakotadigital.com/index.c...rod/prd126.htm
If that link doesn't work, its the "SGI-5" Universal Speedometer Signal Interface.

[ErikB]

Ok, I think I can see it in the pictures now that I understand. If you look closely at the relationship between the tranny holes in the adapter compared to the t-case holes, you can see that Marlins "swings" the opposite way from Inchworms.

I dunno, kinda hard to tell the more I look at them. I'll just go with what they said.

I sent Jim a link, so hopefully he'll pop in and clarify anything I might have made as clear as mud.

Here's an AA V6 adapter (no clocking) for comparison also...

ya i didnt know they made a clocked one for the 3.4. i have the 3.0. that would have been nice to know.

[toyin]

Thanks Eric that makes it pretty clear now. Nothing against Jim's products but i'm surprized that marlin dosent' do the clocked 3.0/r150 adaptor. Guess there's not really any reason when i makes the clocked duel adaptor.

So then does that mean Pauls gonna wanna run the older r150 due to the different tail section on 3.4/r150 or did i just read it wrong?

yeah my name is team ramrod on there. I just got some 16" coilovers for the front and everything for a three link + panhard and coils for the rear so it might end up even a little lower hopefully

[toyin]

This is probably a stupid question but why are you putting the 16'' in the front and not in the rear?

[toy86]

dont wanna cut through the bed. Its my dd and I haul alot of shit with it and dont think i'd have room for a cooler if I had a shock hoop coming through the bed. theres only 15" between the floor of my bed and the axle and the shocks are 26" long fully compressed

[what I wrote earlier DELETED]

The guy @ MC was wrong.
Jim at Inchworm straightened me out, and I verified it myself on my 4runner and T100 as well:

3.0 and 3.4 V6 t-cases are all top-shift (except for some rare exceptions, possibly only on some non-USA trucks). No need to swap out any shift rods!

Going to the geared cases, the shifter may end up further back than before, and Inchworm provides a short plate with two holes in it so you can cut/weld the shifter to move it forward, so it ends up much like Marlin's "dog leg shifter" pictured below.

Also, Inchworm's 3.4 adapter is $400 vs. Marlin's $350, but it has clocking options that Marlin's doesn't. And Inchworm's tech support seems to be better as of late too.

I picked up an Inchworm adapter and I'll post up some pics of the clocking options later.

[ErikB]

In the meantime, here are a couple pics of Inchworm's 3.4 V6 adapter from the install instructions on their site:

T-case holes:


Transmission holes:

[ErikB]

OK, a little update for this thread.

Here is a pic of my Inchworm 3.4 V6 adapter. I circled all the "stock" bolt holes and drew arrows to their matching "clocked" holes.

The 6 bolts going into the reduction box (center and bottom) are installed in the stock location and you can see the unused 10 degree clocked holes next to them. These will clock a pass. drop case up 10 degrees. The adapter plate is aligned by mating with the reduction box front bearings, similar to how a dual case adapter does.

The transmission side uses 8 bolts and two alignment dowels. They appear to clock the same direction as the reduction box holes, but since they move the adapter instead of the t-case, they actually clock the opposite direction. They clock a driver's drop t-case up 15 degrees.

If you use the clocked holes for both the tranny and t-case, you end up clocked 5 degrees up for a driver's drop t-case, or 5 down for a pass. drop case.

If you are using a driver's drop t-case behind the reduction box, that second adapter has more options for clocking as well, up to 45 degrees total, etc.

Hopefully that makes sense.

Also, some of the unused holes need to be plugged and plugs are provided. Inchworms install instructions tell you what to do. Install was pretty straight forward.

excellent! yes, i had too many probs with marlins phone people...unfortunately...

i bought all the 23 spline stuff and an adapter plate thru trailgear...i still need to return the WRONG plate i got from marlin that was suppose to work according to the phone people(its been sitting collecting dust on a shelf in my bedroom for months...

im getting the actual adapter plate from jim, i havent bought from him since my first truck got duals, time to spread the $$ to all the good companies out there...

i dont know if ill even clock my stuff, the lower links hang down far enough to make it kindof unessesary, and i didnt turn the knuckles on the 60 so the front shaft may be happier when the pasenger side drops in a hole...

[jedrattle]

I am pissed off now!!!!! I have been waiting for 2 1/2 months for a rotated case adapter from Marlin.( I want a flat belly when I do my V6 conversion) They told me the V6 trans adapter would clock the cases. So I bought a dual case adapter from TG. I was going to put this in today!! Fawk!!!! I cannot win for losing right now!!


Wtd...I have a Marlins V6 adapter and a 23spline TG dual adapter. I need the cheapest way out of this mess.

I HAVE THE V6 ADAPTER PLATE FOR THE 3.0 V6 THAT THE PHONE GUY SWORE UP AND DOWN WOULD WORK ON MY 3.4...i havent attempted to return/swap it yet, but its new in the box so they better! if theyre outta stock they better refund my $$, as i would rather buy from trail gear or inchworm do to the 'PHONE' guy....
