Have you ever seen a 76 FJ40 with full time 4WD?

[JohnnyC]

but for the amount of work that went in to setting them up I'm sure Toyota made more of them.

John

i'll keep looking

very odd to see in itself...a 1978 bj with a vacuum shift...old school ...nice

Very odd - so not stock? Never had the fun of three speeds and vac engaged 4wd - strictly 2F onwards. Unlikely I will run into anything older in the UK as well - but now I know what to look for.

FJ-62 has vacuum shift don't they. Toyota always had the vacuum shift as an option, and the nose cone is easily switched around. Actually it was designed for it, not external shift. Look how clunky the manual shift is, compared to the elegance of the vacuum, and the early cable for the H L part of the transfer.

And that is what that yellow bj is, regualr old part time for sure.

Hell the FD switch is just push(pull) button 4wd. Us cruiser owners should be privledged that we had that way before anyone else

how's it going Henry, dave gore here.
I believe the 60 that's in the pics here from az is the one Blair bought from the local high school. Apparently toyota donated all the trucks from that test run to schools and other publlc agencies after the project was abandoned. When Blair picked it up it had less than 8000 original miles and had never been liscensed for the street. It was used by the physical ed dept to drag equipment around the high school football field. The T-case was a borg warner manufactured, direct bolt in quadratrac unit. I believe the Borg Warner part # was a 1306 or 1308. It's been a long time but I remember the number was close to the jeep quad, #1336.

here is a little tid bit from Henry C.

Recently there was a thread on a rare FJ40 with full-time four wheel
drive, and the consensus of the list was that no such thing ever
existed, and that the Cruiser in question was probably modified. Well,
in a Toyota Trails-related conversation this morning, I stumbled (and I
mean stumbled!) onto ANOTHER one of these Cruisers! Apparently, the
story behind this is that in the mid-70's Toyota was experimenting with
it's own version of the Quadratrac system (available in some of the big
Jeep wagons), and a few of the prototypes tested in the United States
eventually trickled into private ownership. One of these is a '76 FJ40
currently being used as a prototype vehicle by one of our new
advertisers (name withheld to prevent them from being swamped with calls
from curious Cruiserheads), and according to our contact, it has the
t-case lever on the opposite side, the t-case lever is labeled
"4WDHI-4WDLO-LOCK" and everything is Toyota. Look for a feature article
on this rare beast in an upcoming issue of Toyota Trails!

Was there ever a story in the Toyota Trails about the vendor who had one?
I know who the vendor is who has the one mentioned in the letter to TLCA. We exchanged emails, including pictures years ago

 

[JohnnyC]

Hay John feeling nostalgic? Lol

I don’t thing I posed this here before … only emails to you …. But …
In 09’ I contacted BorgWarner … dead end
In 10’ I contacted Aisin-Warner the present day Aisin AW … dead end
In 09-11’ I was in contact with toyota tema and came up also empty

I did find out “early Toyota automatic transmissions were built by BorgWarner,
later Aisin, now AW”

But there is no other information about any early partnership of the Awd system used … one day maybe we can try the vin and see what it comes up with?

I don’t recall ever seeing a TT article … but… the vendor did have the truck posted on his site at one time and even displayed that it was a prototype… seversl years ago I did find he still had it … see pic below from his site around 2011?

 

[Living in the Past]

Well hay back to you Johnny. Probably still have the old emails. As I remember you had found out Borg Warner was in Japan and had a relationship with Toyota but no information on Toyota using B/W transfer cases. Not sure they is any information to found from Toyota almost fifty years later ViN or no VIN.

Mine the VIN dates it as a 10/75. The other one is 12/75. Only difference between the two as far as the 4WD system the 12/75 the cable (not vacuum) moved to the dash from the transmission cover.
12/75

10/75

Floor mat from the 10/75

 

[Living in the Past]

Not sure this thread mentioned that the Borg Warner transfer case is longer than the stock Toyota case. Because of this a custom torque tube was made and hole further back on the right side of the frame was drilled and used. Both cruisers in this thread have the same hole and the original hole that was never used.
10/75

12/75

Both Borg Warner transfer cases have adapters to use the factory hand brake.
10/75

12/75

The way the torque tube fits thru both sides of the frame rail on left and right this was installed before the four sides of the frame rail are riveted together. Not sure how someone after the frame was assembled would removed the original torque with four welds, drill two holes, install a new torque and make look factory. But also have the now non used holes had welds ground off and look like original drill holes. It's not possible to install a new torque tube thru four holes in the frame without enlarging the holes.

Speaking of knowing a guy, you're 1 of 4 with a "factory" Full-Time 4WD FJ40 t-case. Will you please share a photo of your t-case, shift knob and glove box door panel. You kicked off whole factory full-time 4WD FJ40 discussion and then dipped when folks like me asked you to share some pics. Sharing is caring.

Didn't realize the number was up to four? I don't follow the thread this was posted.
Here is some fresh pictures from yesterday.

 

[Living in the Past]

I am rarely around this cruiser. It is stored away in a corner covered with sheets. Then a bunch stuff stored around it. For personal reasons I haven't been around in the last couple of years. This time will only last a few more weeks.

Here is the transmission listed on plaque on the right fender.

I am not convinced it is a standard H42 with a Borg Warner bolted to the back. Here fill on the PTO blank off plate. It further back than other H42s.

Drain is at the front on the right side.

There are two ridges cast on the bottom offset from eachother.
The rear motor mounts and cushions are different as well.

 

[cruiseroutfit]

Very cool!!! Thank you for sharing in such detail. Interesting they call it. I'd be super interested to know how the t-case works, i.e. what it is doing for a center diff and how it locks. I'm not familiar with the Borg Warner full-time t-cases so perhaps it's as easy as using stuff they had from different applications.

Thanks for bringing this thread back up!! Very cool to learn this stuff.

It’s an M Series/M42 transmission. M Series were used in all sorts of Toyota vehicles… Coaster, Dyna, Toyoace etc. It sits below the H Series on the size/strength list… Toyota may (?) have used it to save a little space for the conversion. Neat stuff, thank you taking the time to grab some pics.

Thank you for the M42 information. Makes sense they would use a smaller transmission since the transfer case it a lot larger. I might crawl under and measure the length of the transmission to that of the H42 in my 79 FJ40.

Personally wonder why Toyota chose the FJ40 and not the FJ55. The Torsen diffs were around at that time and think this would have been a perfect setup for area that got a real winter including black ice. Believe is was 2003 Toyota starting putting Torsen in the full time 4WD transfer cases.

 

[bjowett]

You are welcome.

Torsen didn’t see use as a center diff for another full decade, 1986 in the Audi. They are great diffs… Yes, 2003 for the light duty chassis, and then 2008 for heavy real LC chassis. PDI Australia manufactures one for installation in the 80/100 Series transfer cases. So these days, you know, an option exists for building something in just about any LC platform.

 

[JohnnyC]

Found a diagram of the M41 (thank you @bjowett !!)… looks like most every one I’ve found are column shift and the floor shift are with levers … so the M42 is a straight floor shift? and fill plug mounted on inspection plate/pto cover

This looks like yours John?

It seems the case may be the same 4 speed and 5speed but the 5 speed has a longer rear section addition

 

[peesalot]

if its anything like the quadratrac BW made for the Cherokee Chiefs its junk IMO.
Matt, basically there is a torque converter in there.

 

[bjowett]

The M is built like a slightly smaller H, with 5th gear added/hanging off the back. Some discussion and a comparison that includes a 4x4 version Toyota M vs H Series Manual Transmissions - https://forum.ih8mud.com/threads/toyota-m-vs-h-series-manual-transmissions.1311215/

The M may still be in production in updated forms…. I have an M153 5 speed 2WD that came with my 15BFT which was from a 2000ish Coaster.

M above H

 

[red66toy]

Super interesting stuff!
I also love that the M transmission came in a 5 speed column shift variant! Definitely need to look into that more.
