My 1991 hdj81 I imported is getting a transplant!
Rewind about a year, I had that bent timing belt idler on my california vacation. Replaced, ran great. I started noticing a slight bearing noise about 8 months later but it never got loud or bad. fast forward x amount of time, I was driving up north to visit friends in Seattle, and the timing belt tension bolt shot out the front of the engine, and the idler bearing separated itself from the base! All Toyota parts, all torqued to proper specs. That was pretty upsetting day lol. This time I had a feeling the poor 1hdt had got it rough, so she sat at my friends for a while, and I started gathering cummins parts.
I felt bad about salvaging a good running dodge truck, and I searched for a few months for preferably, a wrecked P-Pump dodge. as I'm sure lots of you know, that's not easy! I almost gave up because I just couldn't find a nv4500 p-pump that was wrecked. I almost bought a few nice trucks, test drove a few that were garbage heaps but ran decent. almost bought one but 1st gear was shot. Gave up for a few weeks. found one on facebook that someone gave up on.
I found a 3500 single cab nv4500 4wd that had been wrecked and then was underway of being turned into a wheeler but never finished by the guy I bought it from. The 12valve was rebuilt in 2019 by the guy he bought it from, and then wrecked. The original owner had the P-pump built at a shop in Eugene, and after a phone call and some emails I figured out that it was a performance built pump with uprated injectors. It's also got headstuds, KDP, a new clutch, the whole 9 yards. Hooray! I got the one I needed.
onto the carnage!
bent valves, slapped pistons, smashed shims, and somehow, stripped gear teeth! I'm honestly impressed. I was fortunate enough to have someone from Canada come down, buy the engine / trans, and help me pull it! She's toast. hopefully they can use stuff from it.
So currently, I'm waiting on parts from AUS to arrive so I can drop the cummins in, and bolt the nv4500 to the factory transfer case. I'm trying to retain as much of the factory functionality and parts as possible. Being that diesels were never sold here I looked overseas for info.
I'm currently working on wiring and how i'm going to manage my fuel system. I think I will use an airdog, and just hook it up to the factory fuel lines and see if that works. ideally i'll be able to remove a lot of excess wiring as well.
the A/C and alternator is another obstacle as the 1hdt has v-belts and the cummins is a 9 rib. I might attempt to use the dodge parts. guys in AUS dont due to lack of dodge availability, it seems.
More posts soon, don't want to flood the fist post with too much info. I'll try to document as much as I possibly can.
