Hi,
Yeap, it is yet another 6bt swap, and I think this will probably be a bit controversial. Let's begin with the current situation. I have an 84 HJ60 with a 2H engine and H55F transmission. It has 33" with a 4.11 diff ratio. (I was swapped with BJ60 ring and pinion when I installed the TJM lockers). I also refurbished the spring front/back, and we adjusted it like 2" lift and added airbags to the back.
Now, let's continue with the controversial part. I am starting to rebuild a 6bt and will put it into my HJ60. The engine comes from an old dump truck. Firstly, I will not do an SOA. Many threads mention that putting a Cummins in 60 without SOA is impossible. However, I will try. Probably oil pan needs to be modified. And the second one is I will use my H55F with a custom adaptor. Maybe I will use the flywheel of the H55F with an adaptor or modify the current flywheel on the 6bt to fit H55F's clutch. And again, many posts mention that 6bt will destroy H55F. I will configure 6bt, not for the crazy power. Just a little bit powerful from the 2H for the hills and longevity (finding parts for the 2H is getting hard).
Also, I will use my original radiator, add an A/C, add NPR high output 24v alternator with the vacuum pump, and use the power steering pump which comes with the engine.
I think the journey will be quite interesting and gonna be looooooooong, but again, I just wanna try. I have read lots of posts, and I am puzzled and confused. I will post everything about the swap in this thread and explain what I am doing with photos and what is going wrong.
Please, I will appreciate all your comments on why it is a good idea or not or possibilities or I don't know anything.
And last famous words: what could go wrong?
Thanks
