Fair enough. You wrote that the injection pump had been replaced by you. Did you line the lines up even or is the pump to one side of the engine line a little? If you turn it one line width to the drivers side. You won't cause any problems and probably get a performance pick up. Not much...

Injection pump timing might gain you a hair of performance. But, as has been written. Once you get to where you are pushing the pedal down further and nothing is changing. Just back off to where you can make changes and keep it there as the speed goes down. If smoke is coming out of the...

Welcome to the fun. At the top of the page there is a tab labeled "TM". Open that tab then click on the very first thread called "TM's for the CUCV." Then open the one that ends in -20. Appendix F of that manual is a complete very detailed wiring diagram for the entire truck. The CUCV...

Correct. Your green routing is what you want without anything else.

The CUCV wiring is very unique but once you get in the zone of concentration and pay attention to it. They are really kind of neat. I had to think about what you wrote in CUCV instead of regular wiring language. The front battery is charged by alternator 1 and that 12 volts is what runs the...

There have been several threads on this site of people putting 6 lug axles under a M101. Lots of people have put regular ball hitches on as well. Expedition Portal seems to always have threads about changing axles on M101 trailers to match up to wheels on 4runners and Jeeps too.

I had the same issue at one time. Pull the in tank pump and verify the screens on it are clear of crud. Then go through the other 3 filters again is my suggestion.

For sure don’t scrap it. We need a little more information and or some pictures to be of much help too. This thread will probably end up getting move to a different part of the site as soon as a moderator reads this.

Yes it has been done.

Thanks for the offer. My filter housing is ok as far as I know. I plan to leave things alone and see what my mpg and driving experiences average out to. But, if I need to make more changes the direction to look right now is for a Banks 6.9/7.3 turbo. Bigger and with a wastegate.

Yes, that is the common progression with them.

No damage. Just realize your IP is a ticking time bomb. I had one with almost the same issues. I did an IP rebuild and all is better for 11 years now.

The CDR valve deals with oil consumption and venting the blow by back into the incoming air charge. It has nothing to do with starting the engine. You can pull the intake manifold off and the engine will start no different.

I’m pretty sure it is on the defrost end and just twist lockers into place.

No problem. I share your aversion to heat. I spent most of my high school years trying to keep a 1967 Austin Cooper S alive. Heat, it always comes down to too much heat. The Mini is currently in pieces while I wait for the machine shop to do some work. Heat again a few years ago. Which...

1976 Cadillac had the Delco 27SI alternator. That is the size case but Cadillac didn’t have isolated ground. Whatever you do don’t turn in your originals as a core. I purchased a kit off ebay a few months ago and it worked fine. Forum member Tow4 at one time also sold kits. Sending him a PM...

Time for some more updates. A year ago on a cross country trip I experienced some high Exhaust Gas Temperature readings at high speeds on steep grades. I wrote a lot about it in this thread and started with timing changes to make things better. Which they did. I have not messed with the IP...

Post #165 in this thread is where I write about it: https://www.steelsoldiers.com/threads/m1007-cucv-suburban-clone-build-thread.74514/page-9 Basically, it can be done. However, to get the full weight rating for the pintle hook I think it will be very tough in a M1009 due to the fuel tank...

It isn't in the way unless you like pulling the vacuum pump or messing with the oil psi sender. So, it can stay on the truck for the original look if you like. Having written that I pulled the non used resistor off both of my M1009 trucks and wired my M715 just like a CUCV without the...

I have a NV4500 behind the 6.2 non turbo engine in my M715. Same basic weight as a M1009 but totally different gears. 5.87 compared to the 3.08. I have to agree that the 4L80E is much better for driving with a low power engine. Especially with any kind of load or trailer. Plus, the NV4500...
