Well, September 4, 2006 was a very big day for old JimmieD, boys and girls! I was finally able to step back and take a look at my Cummins 3.9L 4BT sitting in my Town Wagon, all bolted in place!!! No pics yet, that all comes later.....
This has been far more of a challenge than I anticipated at first. The donor truck used GM drivetrain which cants the engine to a tilt of about 10 degrees. Correcting for that was surprisingly difficult. Fabrication of motor mounts was real tricky as I wanted engine to sit flat on horizontal mounts, instead of traditional angled mounts found in early Dodges. Also the layout of the TW required fabrication of a completely different transmission mount for the NV4500, using Dodge 360 motor mounts and a custom built crossmember.
It ended up sitting straight, level and upright and is stout to say the least. One 360 mount ended up cocked a bit sideways but it won't ever show and I really don't care! Driveline angles look good, and I'll have a nearly flat floor with only about 3"-4" trans hump.
All of this project is being accomplished in a backyard, with dry grass turned to dirt. A nice slope in the yard says throw away the level and plumbbob, and makes it pretty tough to roll around heavy parts on hoists or jacks. The prior extensive body damage adds to the task, plus little info is available out there for step-by-step instructions. Regardless of all that the engine's in, and trans is in, and now I'm waiting on some part$. More part$. Lots more part$.
Pictures eventually.....
