Isuzu 4BD1-T swap into a '92

[Wheelingnoob]

Had a quick question for you. How is the clearance with the throttle lever assembly and fire well with that 7* tilt to the passenger side. That is the only concern I have with mine everywhere else the slight 7* tilt helps clearance wise other than that throttle mechanism.

I got Saturday booked on the CNC to get mine done and just want to make sure the 7* is not too much.

7 fits fine. I think there is a decent pic in the first pages. I'll be lookin forward to seeing yours come together!

Found it, thanks!

Looked at my Isuzu NPR (2003-2008) intercooler and its inlet and out let are actually quite close to one end so I may be able to run the pipes under the rad. Not going to know till I get the rad and engine in.

I also got my possible steering interference sorted out, I got a 4" Slee lift.

How far from driving you are?

We should all meet up in Moab when done (I need an excuse to go), there is another guy in UT doing a 4BD swap too AdamR.

 

[jtaylor]

I should be driving by the end of the day today. I am also going to slap on the slee 4". Moab is always a good time! I will gladly meet you there!

Oh the big day!

I have done a few engine swaps and its always so exciting getting to drive it under its own power for the first tine.

Good luck!

Maybe tomorrow

Ok, so no driving today, but i did get some stuff done. Made a video of it idling smoothly, but my computer is not cooperating with my new camera, I'll keep trying. But I did get the i/c routing dialed in. That took longer than expected. I also tapped a hole for the mechanical boost gauge and plugged that side in. Auto meter lists an "a" pillar gauge pod for the 80's, so probably going to get two of those for boost and pyro gauges.

A little video

Sounding good mine does the same white puffing miss when I first got it running on the stand it was air in the lines. Took a long time to work it out.

Just a word of caution, I would not run it more than 30sec or so with no water. There was a video posted on 4BT swaps of a destroyed 4BT after 2 min of running with no water. Seemed a bit strange but I know you can get hot spots very fast with no water.

Are you planing to make a custom fan shroud? Lot lots of room!

 

[jtaylor]

duly noted

Thanks for the reminder, just excited to see it run.

I have a buddy that works for a large HVAC outfit and he said he has a computer program that will design square to round shrouding. Just have to get the measurements and offsets and what not and it will map out the bends and cuts for you. We're gonna play with this a bit and see if how it goes

So, got a little problem. Trans doesn't engage. After a couple emails with Dustin this evening, I can only guess that the problem is the pump. Anybody got a picture of the a440 pump? I have an A442 pump sitting around to compare it to. There has been only one other guy according to Dustin that has tried to use the A440, and he gave up and didn't figure it out. He ran into the same problem as me, but never did anything about it. If changing the pump doesn't work, I guess the A442 is going in, electrical control and all

 

[thadscottmoore]

that sucks! I hope you figure it out. hopefully something simple...

 

[Wheelingnoob]

Give me a few mins Ill drive to my shop and take a picture of the pump and the converter/pump interface.

 

[Wheelingnoob]

Here is some pictures of the A440F.

Pump



29mm



50mm

Tried the measure the depth of the pump drive teeth think i got them.


Base of the teeth 115mm

Top of the teeth 97mm

Those last ones where hard to measure so there maybe a bit of error there. From the bell mounting face of the case to the converter seal surface is about 40mm as well. No picture of it. That is as close as I can get on that measurement again its as close as i can get.

I have a feeling the pump drive teeth are deeper on the A440 than the A442. The two pumps are quite a bit different looking at the two. Sorry to hear about these issues stuff like that is really frustrating.

Thanks for checking that for me Jeremy, I'll measure the a442 pump in a bit, and compare notes

No problem, hope it works out that its an easy fix vs having to swap in a A442 and all its challenges.

I did speak to Rodney at Wholesale a few months ago about swapping converters from a A440 to a A442 unit and they said it was not possible but no reason why. They also said the pumps can not be swapped from A442 to A440.

I'm kind of surprised none of this was checked (if that's the case) before recommendations where made that the bell and converter from a A442 could be used on a A440.

 

[mjosoba]

Hmm. I bought one of their adapters with the understanding that it was no problem to use the A440.

If you unbolt the Converter from the flex plate and push it back into the bell towards the pump does it move back at all? If so how much?

Something in that converter to trans adaptation is not engaging really the only thing I can think of is the pump drive teeth because of a depth difference.

Another test you can do is try removing the cooler line from the transmission and see if you have any fluid movement.

 

[jtaylor]

Figured it out!

Ok, so there is no fluid movement, none has been pushed into trans coolers. I did fill the converter with fluid and installed it properly per the manual. So the pump is not being engaged by the converter.

Ok, so here is the bomb, the toyota part #'s for trans pump and interplanetary shaft are different on trucks with a build date after 8/92. That means the a440 and a442 do not share the same pump and shaft, and the adapter was designed to use the a442 pump and shaft.

But Dustin said it would work? Dustin messed up, he told me that when he went to a used parts supplier to check out the differences in the pump, they might have given him two a442's instead of one of each. Looks like that is what happened. Bummer that he didn't do a little more research. It took me two minutes at the dealer to get the #'s. Oh well.....

There was one other guy that has tried to use the a440 according to Dustin. He wasn't succesful either. Which makes sense.

So the solution is simple, swap in the A442.

Or what about spacers between the flexplate and converter, meh, they would be impossible to put in. And add some stress to plate too.

So I am open to other suggestions, but it looks like the best one is to swap the trans, It worked on the Predator(I've seen the video), so we know it works with the adapter!

a442 pump

I can see a difference, even without measuring

 

[Wheelingnoob]

Yeah that's what I found with the part numbers as well. That sucks big time!

Not sure I would be very happy about that, part of the simplicity of the swap with the non ECU controlled A440 is lost. Not to mention all your time and now added cost to get the A442 and the compushift.

Hope no one with a 60/62 got one of this kits its not an easy swap if possible at all to the A442F.

Only option I could think of to get that converter in enough to engage the pump is to have Dustin fix the issue and press a new flex plate with the correct converter depth. That is the simplest and most cost effective.

Good luck, was hoping that other one was a fluke but appears to not be the case.
