I know there are others out there... lets post them up!

Great idea

The early Isuzu 4HK1 also used the AW450 transmission before they switched to the 6-speed Aisin AW465. The 4HK1 is basically the same block as the 4HE1 that it replaced so the starter is located in the same location as the 4HE1. The 4HK1's displacement was bumped up to 5.2L, uses a 4-valve/cyl head and a computer-controlled fuel rail injection system.

The Isuzu 4BD2 never was mated to the AW450.

now wich ones have a starter that faces forward.. I know the mitsu 4d34 does..wonder about the 4d50...

All of them except for the 4HE1 and 4HK1

I am compiling pictures of each engine and will add them to this thread...

4D34 and AW450-43LE 1999-2004 Fuso FE, FE-SP. They offered this driveline along with the 175hp 4M50 for a few years.

Pics of some of the engines above:

1999 ISUZU 4HE1

1999 NISSAN FD46TA

2004 NISSAN JO5D (Same as in Hino?)

2005 MITSUBISHI 4M50

2001 MITSUBISHI 4D34 (Fromage's build)

 

[ZDOG]

Anyone know the part # to that adapter plate on the 4D34?

Looking at some pics of older Mitsubishi 4D34s, I'm wondering if the plate from a 1999-2004 4D34 could be used on an older engine.

 

[cruiserbrett]

The later model nissans (UD) do use a Hino engine. If you look on busbys wrecking website, they have closeups of the data plates on lots of the overpriced engines they have...and it will say Hino on it...

 

[SuperHatch]

That is correct... I believe the changeover started when Nissan sold the UD division.

Bump... my 4D34 conversion:

Also, it appears that the 4M50 and 4D34 have the same bellhousing bolt pattern, so swapping to a 4M50 at a future date may be very very simple. Not that I'm even thinking about that right now, but it's good to have options open if I came across a very cheap truck.

I found a 4m50-1at2 with an aw450 on the back of it today, in an `03 Fuso FE-SP... Is this a viable option for my fj62?
Anyone know if they share blocks or if the 4m50 uses a larger casting?

This is the only info I could turn up, nothing about dimensions; been posted before.

The 4M50 and 4D34 do not share block castings... the 4M50 has balance shafts and a different IP arrangement than the 4D34 just for starters. It is a completely different engine.

The fact that the truck you found has a AW450 transmission means it will be a candidate for you FJ62. Just follow what Astr did for his transmission build and you will do the same thing.

Yup, thanks SH.
I've done a bunch of review since I posted this yesterday, on my third time through Astr's, yours, Fromage.... sorry for the HiJack.

Cheers,

That is no hijack, it is exactly what this thread is for.

 

[DIESELJEEP]

Does anyone know if there is a specific vin code we could look for to make it easier when searching for a donor vehicle.I'm asking because I seen a 97 mitsubishi diesel fuso and the trans looks similar to the aw450-34le but I read they were not offered until 99.Do the transmissions look that much alike between the years?If so,what should I look for to make sure I get the compatible transmission?

IIRC the pre-99 Fuso's used the JR403E as Isuzu and others did.

 

[Pacer]

DieselJeep, does the trans have a blue Aisin sticker on it, down low on the left side?

Versions of these trans' have been around for a long time, and remember, this list is not yet complete/definitive...

Post up a pic.

 

[SuperHatch]

I have seen the auto in a 98 and a 96, both were Jatco autos, not Aisin units. This does not mean they were all exclusively Jatco units, but it does coincide with that the FSM for 96-98 trucks states.

 

[Pacer]

Does it look like this?

edit: whole new post (didn't feel like cluttering the thread more)

2005-2005 Isuzu n-series trucks also have AW450-43LE transmissions. They also have the larger 5.2L DOHC commonrail diesel with 173 hp and 368 ft-lbs. It takes guts (or a lot of knowledge) to tackle the electronic common rail system though (vs 4he1 which runs no problem with NO computer-might have less power though, I've heard the ECM can advance the injection timing. I haven't seen anything on the pump itself to prove that though, just the rpm sensor and the fuel rack position sensor).

It has the same block as the 4HE1, but a new head and no injection pump (I wonder where the starter is since the rear gear casing is different due to not having the injection pump?)

more information:
-AVOID 1999 Isuzu N-series 4he1 engines. They used a fine gear system for the injection pump, camshafts, etc, and although that makes them slightly quieter, they are prone to stripping the injection pump gears.

Fueling mods to get more power will speed up this wear drastically (and I know you want them)

2000-2004 trucks were changed to a coarse gear system which fixed the problem. They also had to change the computers (both ECM and the TCM) to read the engine rpm (wiring harness is identical though)-engine rpm is read by sensor on the injection pump gear (99 ones read 72 teeth per revolution, newer 00-04 ones read 36 teeth per revolution)

If you get a steal on a 1999 engine, no worries you can change the gears for the coarse ones with no modification (although I've heard it's very difficult to get the gear off of the crankshaft). From my research the gears are roughly $500 for new OEM ones.

-how I learned all this: replaced the engine in my 2000 Isuzu npr (I got it for $1800 with a thrown valve head) with whatever was available, which was a 1999 engine. I had to get a new TCM and ECM (It drove without much problems with the old one, but occasionally it wouldn't want to shift into 2nd unless I completely released the pedal and then it would shift hard) and I'm keeping an eye on my injection pump gear wear (I'll be measuring tooth width every 10,000 miles- it's at 130k and still looks good, but the first time I took out the sensor the magnet part had a very small amount of metal particles stuck to it). That was probably the original sensor with 130k miles of wear on it though.
