Well…I guess it’s about time I started a thread on this one.

DUMPIE:

Build - "Dumpie" my new Fj45 work truck! - https://forum.ih8mud.com/threads/dumpie-my-new-fj45-work-truck.970647/

Fire while being Transported:

fj45 destroyed while being delivered in Central Valley - https://forum.ih8mud.com/threads/fj45-destroyed-while-being-delivered-in-central-valley.1152302/

In September of 2021 I saw Brian @whitey45 mention that Dumpie might be for sale. I reached out and we struck a deal. Dumpie would sit at Brian’s until I could figure out timing. In September of 2022 after I closed RT8 Donuts I drove from VA to CA to pickup Dumpie.

Dumpie gave Rob @landcrusher909 a run for his money on the Bonnieville Salt Flats on the way home.

As is my tradition no cross country drive would be complete without a mandatory stop at Joe’s in KC.

I moved to Denver for flight school in April of 2024 which then opened up the western US for chasing parts I needed. In July of 2024 I struck a deal to buy a bunch of takeoffs from a high end resto mod. I needed several parts from it to complete Dumpie including the extremely rare FJ45 taillights.


A couple months later I purchased a correct US Spec bed from a 1967 FJ45.

I found a buyer for the AUS 45 Spec 3 bulb bed. He came down from Northern VA and has fallen deep into the 45 rabbit hole.

Alright guys so…here’s the issue:

On Dumpie the 1F engine won’t turn over.

When we stuck a bore scope down the cylinders no visible rust was present.

We’ve tried turning the nut on the front of the engine with a breaker bar.

Soaked the pistons for 3 weeks with a 50/50 solution of ATF and diesel and pumped out the mixture.

We took the valve cover off and verified all the valves are moving freely with a couple light taps from a dead blow hammer.

We’ve put the transfer case in low and high, locked the hubs and engaged the 4 wheel drive using a home made adapter and shop vac. For those of you wondering it’s the hose closest to the firewall that engages the four wheel drive. We know this worked as the front driveshaft locked up.

We hooked a truck to it and pulled it forward to try and get the 45 to use the mechanical advantage of the gears (in 1st and L in 4 wheel drive) to turn the engine over. It squats the front end and proceeds to drag all 4 tires. The PTO shifter is disengaged.

So…here’s our question:
If we leave it in first gear and pull it backwards will it actually spin the motor backwards?

Feel free to make any suggestions you deem appropriate after reading through what we’ve already done.

This is very weird? Did you ever get it running? I had it running a few weeks before you bought it? I would pull the pan and check the rod and main bearings? If cylinders are clean, it has to be a bearing issue( have seen it happen many times, but not sure how or why it would happen if you have never had it running?
 
I never had it running since I’ve owned it. I’ll pull the pan and check the bearings. I’m also going to pull the starter and make sure the bendix isn’t stuck or something else is preventing it from rotating???
