For those of you who might want to see how the swap started you can check out this thread:https://forum.ih8mud.com/80-series-tech/673353-cummins-4bt-into-97-lc.html
I am now going to be using an Isuzu 4bd1t that came out of a 1990 NPR.
Here is a little back story to how and why the change occurred. After I bought the 4bt, I found out that the 4bd1t was also a popular option for diesel swaps. So I started looking for a 4bd1t and in almost no time I found a 1990 NPR that was about 4hrs away round trip for $1000.00. It hadn't been started for about a year and the radiator and been seriously damaged by someone using a skid steer to move it. Anyway with a little battery tinkering we got it to start, then pumped most of the ATF fluid onto the ground (apparently at the same time the radiator was damaged they f####p a transmission hose). It didn't run long enough to actually drive it onto the trailer as planned so we had to push it on with the same skid steer that was the culprit in the aforementioned damage. A couple of hours later and back home we figured out why it stopped running, ran out of fuel because there was an open fuel line that was sucking in air. It had another diesel on the back that ran a street sweeper and they shared the same fuel tank and it was that fuel line that sucked in the air. We got it primed back up and after that she would start up no problem.
So I had the drive train from the NPR sitting in my shop and I had the drive train from the LC sitting there and I happened to read the following thread and it got me to thinking.https://forum.ih8mud.com/diesel-tec...suzu-4bd1t-swap-part-ii-now-w-a440f-auto.html So lets see if we can accomplish something similar with a newer 80 series and a different transmission.
In the first picture I have the Isuzu bell housing bolted up to the A343F Toyota transmission via a piece of plywood that is acting as the temporary adaptor. The second picture shows the two torque converters with the Isuzu on the left. They are very similar in size, but I think I am going to need to use the Toyota and attach it to the flex plate mounting ring that is currently on the Isuzu. I will post up more info and pics tomorrow.
