Differences between '74-'80 4 speed and an '84 4 speed. Interchange?

[island45]

When I pull my growly transfer case off it's original '79 transmission I suspect it may have the typical hard ware on the output splines like I saw on the last 4 speed I had. If so, I have a four speed with much lower miles, but it is an '82-'84 from a rolled over fj60. It's been in a dry shed for 20 years. If needed, will this later transmission bolt right up in place of the earlier one?

 

[EWheeler]

No. Output on the FJ60 is 19 spline for a split case, output on your ‘79 H42 is 16 spline for the one piece t-case.

Unless you plan on using the trans AND t-case from the FJ60 as a mated pair. It can work in that case with some likely minor issues easily overcome.

 

[bikersmurf]

I’ve never had my hands on a newer one… but I believe it bolts to a split case. My understanding is a split case won’t bolt onto my older transmission :. The newer transmission won’t bolt onto a one piece T-case.

60 series transmissions also have the shift cane mounted 3.5-4” further back. It can be compensated for, but it’s also different

 

[island45]

Excellent info guys. Thanks and I will be hoping to find a decent output shaft on the '79' transmission. If not, I will deal with it.

Another issue would have to consider with a 8/80+ FJ40 or FJ60 is neither will a have hand brake on the back of the transfer case. Only the 8/80+ FJ45 and HJ47 had a hand brake on the split transfer case.

The 40 series always had a cast iron top on the four speed. Most likely a pre 8/80 40 series four top would fit on the 60 series transmission except for the reverse light switch which moved from the back to the top of the cover on the split transfer case.

Later (83 and up) HJ47's usually had no parking brake drum behind the transfer since it moved to the rear axle. There are input shaft spline count variations too between the diesel and petrol transmission variants.

Input shaft on the B diesel is different. H diesel is the same as the F petrol engine.

Not aware of any 40 long wheel base 40 series manufactured in Japan having a hand brake on the rear axle. Markets in South America have different parts. I know Brazil were locally made and Venezuela used a Dana rear axle. Columbia had locally made hard tops. Africa had locally produced parts. I'm sure there are more.

But never heard of any fully manufactured FJ45 or HJ47 having a hand brake on the rear axle. Because Toyota was standardizing production from the late seventies on. That includes the torque behind the transfer case and fuel tank behind it. There wasn't clearance for the hand brake when an H55F five speed was installed. The transmission hump changed on all models including the FJ45 and HJ47 10/82. This was for the taller H55F. Because the hand brake remained the transfer case of the long wheel base the H55F was never offered in a long wheel 40 series. There wasn't enough clearance in front torque tube.

This was either a May or June HJ47 from Australia.

Only piece of the running I didn't buy was the 2H engine. Has the hand brake on the transfer case. The rear axle does not have a hand brake or any sign it ever hand one.

Always a time to learn. Here are the OE numbers for the rear axle parking brake option -

And no, this is not a Dana diff and Merc engine'd unit from South America but rather a Japan assembled setup available in the General Markets.

I just put a early 60 trans and split case in my 40. The earlier 60 series are shorter. All I had to do was switch my top plate from my '78 40 H42. I'm going to do disc parking brakes since I did the rear disc conversion. Ruff Stuff sells the '78 Eldorado calipers with the parking brake. Going to utilize the OG pull lever under the dash.

Valley hybrids have split case P-brake from later 40 series

Some 60 series h42 have , kind of a spacer on the back , so it is the same lenght as an h55 , problably to mount the crossmember at the same place for both set up

 

[mattressking]

Easily done.

1. Use a 80-84 Fj60 trans/splitcase (NOT mid '85-'87 H42, you can use this splitcase and some/many prefer 38mm vs 34mm splitcase)

a. If you buy a brand new 38mm case from Toyota, sans gears, see item 4.​

2. Swap the lid from your 75-79 H42
3. Purchase OEM split case mounted parking brake from Valley Hybrids.
4. Install 3:1 gears for more fun

Lots of good info here, but really I was only wanting to know if I could hang the one piece '79 case on the back of a FJ 60's four speed in case the output splines were badly worn when Ipull the existing worn out case off for the swap. In my shed I had a 60 series tranny and t case and a '78 tranny and t case from another 55 I had parted 25 years ago. I knew well what was needed to go the split t case route and figured at 70 ys old and putt-putting around the island with my grandkids, a t c rebuild of an original would be cheapest/easiest and I certainly won't wear out trhe rebuilt case any time soon. Most likely I will just pull the existing growling, glitter filled t case and install this fresh one. It was a fun exercise to rebuild this case and I love those Japanese gears and bearings I got from Kurt. Just hoping to see some decent output splines. I still have the ability to use the '78 trans that was hooked to the case I just rebuilt. Like so much on this vehicle, I doubt I will be shearing off the transmission splines any time soon. The moral of this story? :
If I had it to do over again and knew then what I know now, I think I would just stick the complete 60 series package (without opening it) Fab up a crossmember and ebrake assembly and drive on. Waiting for the concrete floor under the Foyota to warm up before I swap this rebuilt case in.

Just for the record if you did go with a split transfer these are the three pieces required to use with one piece transfer case hand brake setup to make it work. I've sold a few of these for a friend in Australia. That been a number of years. Price was $550. Not sure what these parts sell for today but expect it would be at least this much.

That is a killer deal on the parts these days IMO. The OEM rear retainer alone is the real scarce one, the shaft and drum readily available new. We do have modern manufactured rear retainers fwiw. I’d be super curious if your friends has more sets available, preferably the bearing retainer only if possible as we use new on the others.

We’ve discussed this, you can’t forget the 60 Series that had the t-case mounted park brake.

Still trying to get my parts here from Australia. I have two sets with the retainer and two 10/82 34MM split transfer cases with the hand brake over there. If I can get them here that would be for sale.

Unfortunately I can forget. Never been the sharpest pencil in the box. Getting old isn't helping. I remember seeing the 440 series frame support for the cable. Just didn't remember seeing it on the 40 series. Not having the master catalog can't figure the difference between FJ45RP-K and FJ45RP-K3? This and the same HJ47 are the only long wheel base models having the hand brake on the rear axle. No Q so it wasn't used in Australia. Not sure New Zealand got Australia models. Non in Europe, North America or Japan. Only the Middle East/Asia market. Thinking RHD would be Africa and possibly Pakistan. The brace wonder if the 3 means cab and chassis? With no bed it would need a support for the cable hand brake on rear axle . But that's just a guess.

Would wonder why for such market make a special model. Four wheel steering on FJ55s in Australia used in the mines is another.

Another is if Toyota was actually involved in the full time.4WD prototype back in the mid 1970s. I obviously have more interest than most.

Thought this was just an English version of.this glovebox door plaque.

There is a difference that makes me believe more Toyota was involved.

Here is a clue.

Of the two known behicles this one is more original. Has super low mileage.

 

[POPO AGIE]

Why is the transfer case lever on the left and the PTO lever on the right?

 

[Living in the Past]

Why is the transfer case lever on the left and the PTO lever on the right?

The lever in the left for high low ranges is because that is the side it is on the Borg Warner full time 4WD transfer case. The knob/cable on the right is to locks the front and back driveshaft together. There is no PTO. That knob is what shown on the glovebox door plaque. What I noticed between the two plaques is the Japanese version it shows pulling out like it does on part time 4WD vacuum operated 4WD. On those it's on the dash. The English version shows pulling up which to my knowledge is only on this one. The only other known one is two months newer and has a lot more miles. That one the knob is on the dash. If it was moved I'm not sure. The dash plaque is still the same.

So you're repopping the retainer? Once I bought a NOS one from George I realized it should be pretty easy to reproduce...or is my assessment wrong?

The handbrake drums and t-case output shafts are available via Australian sources (Terrain Tamer I think) because they were used there well into the 1980s. Are you selling those as well?
