So I received an email from a guy named Eric in Panama
He has a diesel Isuzu Dmax (edited) with a driver side drop front axle. I forget what year and model.
The engine he has is a 4jk1-tc is diesel 2.5 (or 4jj1 -tc is a 3.0 liter same has thailand and australia uses the same MUA5H transmission)
His is the one on the left, or right, I forget! LOL
His plans were to put a Nissan Patrol axle up front under it and do a SAS.
One problem though is that the Patrol front axle is PSD not driver side drop.
That's where his internet searches found me and the huge job I did to SAS my truck and the swap I did from the MUA5 to the Ar5 transmission.
He was very curious about the inputs and outputs of various cases and trans. Some we don't even have here in the USA.
So I helped as best I could.
As it turns out, the rest of the "new" Isuzu world some have these MUA5 transmissions that are DSD (not PSD like our MUA5 trans)
His is labelled MUA5H - there are more: MUA5S, MUX5S but I'm not familiar with those, nor did Eric fill me in on them....
Below are pics of the Mua5H output and the DSD trans he has.
Female input on Transfer Case he has:
Rear output with the Mua5H and the DSD case:
The output is a slip shaft style and not a flange. That is very different from ours!
front input and output of the 4wd on the DSD case
Even more amazing, is that the MUA5H does not have the integrated transfer case. :!: :shock:
It bolts onto the back.
The MUA5 we have in the states has the integrated case in the middle and last clams of the entire Transmission! :evil:
And even more amazing was when he sent me pictures of the rear output and the case female input, I told him to go find a V6 3.2 transfer case from an automatic trans Isuzu and see if it would fit. :idea:
He told me the spline count was 27 and the pitch was the same as what I measured out for the slip shafts on the GM 4L60's.
That is the same as the Mua5 I had and the Ar5 input! :shock: :mrgreen:
Now we're talking. Isuzu was smart enough to keep a good thing going and they did it for years and years.
This sounds really promising that a PSD case would fit his diesel Mua5H transmission. :albino:
So I mod'd a comparison photo: Ar5 output on the left and the Diesel Trans output on the right.
They look so similar!
I sent some rough measurements of the female input on the stick shift transfer case i have.
Getting closer now.....
So Eric pulls an electricly shifted transfer case from a V6 Isuzu in Panama and attempts to bolt it up to his Transmission......
Looks like a 4L30 automatic, anyone confirm from the pic?
Now check out the PSD (left) and the DSD (right) cases side by side:
Well buys and girls... drum roll please......
they line up.
Amazing!
Lastly the driveshaft flange lines up too!
another good thing Isuzu never stopped doing!
Not every single bolt hole lines up but that could be solved with a skinny adapter plate and you now have soooo many more options for front axles.
Now if we could get a hold of the DSD Isuzu cases here in America we would have the opposite options now available!
We could go hunt down the more readily available DSD front axles for our SAS jobs!
:bigsmurf:
I'm going to try to get Eric to join the board so he can share his adventure in Panama with his transfer case discovery.
