Yesterday my D-max let me down for the first time

I started it and after maybe warming for 5 minutes it shutoff all by itself.

Hmmm. so I started it again and it ran for maybe 2 minutes, then died

It did that several times so I abandoned further attempts.

It was around -9F outside so I suspected gelling fuel

I grabbed my trusty spare Quoffee pot and drained the water separator part of the filter into it.

Just look at what came out:


That was Kroger stuff that I am paying less than $3.00 a gallon for with my discount, so I run a lot of it.

I tried an little experiment

I brought it into the house which was 71F and set it on the counter



Then 30 minutes later:


Quite a difference between the stuff below zero and near room temp

Everyone has me thinkin'

Here's the truck as it sits today



And a close-up of the front and rear tires.
That locker is chewing up the rear tires a bit, which I'll gladly accept given the excellent drivability I have gotten with it over the G80 Eaton break-ah-locker

He and another gentleman can actually machine the shaft that broke that Case no longer supports!
Yea...

And the problem with the fuel in the oil.

Leaking injection pump???

Dan the Man's brother is a diesel mechanic

I'm smellin a rebuilt refurbished Big red, which will become Big Green when I OD it out...I can almost smell the diesel smoke from here!

And

Last night

I had a dream of me cruising the farm in the bottom of a big hole sittin on big Red...

You sure do!

To recap, I was looking at several directions. One using all the stock stuff, bolt pattern and so forth with factory 2011+ large calipers.
Next we were looking at using the big Late Dodge rotor which has the 6.5" bolt circle and the Chevy rotor just so the master cylinder still works OK.

Next up was downsizing to the 2010 and earlier Chevy HD setup, caliper and all, and swapping out stuff in the rear to fit the new bolt circle.

Beau was in the middle of trying out a bunch of parts when his company got a huge order from that electric car company. He was distracted from my project to say the very least.

Right now, it isn't a factor because of Square D, but as that project matures and is finished, then the attention will once more shift back onto the SAS D-Max .

Folks, the more I play with this truck, the more I think it is one huge mistake and problem dealing with all this unnecessary garbage.

I am so fed up with all this wiring and electronic do-dads, that I may very well be the first to convert a late model 2500 to 12 valve Cummins power.

No electronic programs to write. No overpriced fuel pumps. Room enough to actually see something, and the ability to work on it without it taking a week and requiring post graduate engineering PHD's.

I am sick with this electronic stuff...Did I mention that already???

Let's talk about the future of this truck

To say the very least, the building of Square D, the 12 valve Dodge 1991 truck has been an eye opener.

I can say unequivocally, that building this LML truck as a survival vehicle is a flawed concept from it's inception.

You see, it's just too complicated to last in a survival setting where there is no access to a parts store and troubleshooting, and tons of support.

It is just too complicated. It is too expensive, and it will not survive an EMP event intact. It would be useless.

Used in the modern world where one doesn't mind waiting for someone's permission to tune or until someone writes a "Tune" or provides extra fuel or figures out how to fit some brakes to make some practical wheels to fit.

Bottom line: Not another cent is flowing into this truck until I decide whether I install a 12 valve Cummins into it, which is choice #1 or just sell it.

The latter would provide a vacancy which I would fill with a much older non computer controlled square fender Cummins powered Chevy or a Crew Cab Dodge circa 1991-1997 that has no rust.

I'm just going to be happy without some widget calculating how fast I am travelling. Nope, I think I prefer a worm gear and a steel cable noisly spinning a set of nylon gears that attach to a orange needle which points to 70mph.

I don't want some complex software computer logarithm determining how much fuel to dump in the cylinder at this exact millisecond. Nossir, I think I'll be happy with a purely mechanical Bosh pump and a mechanical injector which knows not whether it is pumping or spraying diesel #2 or chicken grease into my marine grade engine. I don't want some pressure switch failing and putting me into a limp mode...Fact is I don't ever want to know about no stinkin' limp mode. If it fails, well, wait a moment, it won't be there anymore so how could it possibly fail????
Exactly...
And when I look for a turbo, by golly I want to see it. I don't want to have someone point and say "I believe it's down in there somewhere." When that turbo fails, I want to trip in the dark and fall on it. I want to be able to pull it off in three hours, not three days. I don't ever want to have to delete anything, because, lookey there, it isn't anywhere to be found!
No catylitic converters converting anything. No pre heaters for an EGR that really doesn't do anything purposeful. No strange caustic cancer causing fluid being injected on or in anything, just dump oil dino inspired fuel finding it's way down some equally dump steel line into something with a couple of moving parts and spraying into a horribly inefficient combustion chamber, that, oh, by the way, is producing about 22 MPG and causing a fire that only ends when it runs out of the wet stuff.

How in the name of anything that makes any sense at all have we been duped into thinking tunes or star mags and 20" tires mean anything except that we are all really, really stupid? We gave up $20K vehicles that ran on anything so that we could purchase 60K cadilliacs that can scratch your butt, but go into some failure mode half way across a stream on your first outdoor trek! Why did we give up 20+ MPG for computer controlled engines that don't pollute anything and through the magic of their wizardry produce tons of power and 15MPG. So I pay 3 times more than I need to so that I can get 25%-30% less mileage just so that some geek driving a prius that likes other boys can feel he is helping save the planet?

Well, forgive me Mr. brain dead, self induced comma, I'm getting off this bus...

As I became more and more serious (Focused) on what this build was going to be about, the EMP think became the white elephant in the room. Not so small either was the problem with all this electronic overlay. HEck if any of a hundred different and unknown parts failed, I'd have stacked all my eggs in the single basket and proven only to have been a very busy fool.

Now that I think I have encapsulated what a pseudo combat vehicle needs to be, these newer trucks are not useable. Well, not with the existing powertrain. Now, install an early mechanical fuel injection diesel with a non electronic transmission, either a manual or an old school automatic, and then this truck is in there. Just needs some additional hardening...

So I have to look at the cost of converting it vs selling it to recoup the $$$ and simply hunt down the right early truck to convert.

A thing called a faraday cage routes electrical current around things. EMP is essentially just a big wave of electricity that crashes through things and overloads circuits, destroying them physically.

Military wiring harnesses reside inside a sheath of braided wire which all runs to a ground. It works to a point. But if hit by a big enough pulse, that won't work either.

Something like an old school galvanized steel trash can is a faraday cage. put your radio in there and it would survive intact following an EMP event. I have seen one guy with a length of chain welded to his axle tube, and allowed to drag on the ground. He felt this effectively grounded him and would allow the voltage to flow through the vehicle onto the ground. Thing is when a sewer pipe full of hot rushing liquid meets a fine filter like the electrons of EMP finding a micro circuit, chances are the blockage will get blown out.

No real way of absolutely insuring fine electronics will survive an event, so to absolutely guarantee you have stuff that works, don't use electronics that are essential to it's operation.

BTW, I test drove a 2012 Ram 3500 dually this weekend.

It has a solid front axle so I got a taste of what that would ride like.

I have to say the Chevy has it all over the Dodge. I do like the Cummins engine better, but the ride is all Chevy.

Plus after a few hours of highway, country, and city driving, the mileage on the truck's computer only said 13.4

That's terrible!

Cuddos to the Chevy Duramax guys for getting that engine sorted out

Granted I'm deleted and tuned, but the mileage on my computer said 17.3 when I pulled into the dealership!

That makes the Chevy's mileage 23% better!

Upgrading to second gen Rare Parts Tie rods today

The first set of 1st generation ones are all worn out!

I believe it is a lubrication issue. I pressure washed the truck a lot during the salty winter and that pressure washing blew away the grease me thinks...The sockets were dust filled!!!!!!!

New ones are here, headed over to the shop...

Look at the difference between the stockers, 1st gen and base ball bats about to be installed:

Well before the great candy bar fire of 2014 cast its ugly spell upon me, I was hard at work on coming out with my own site. I/we are going to pull these threads/posts and feature them on a pay part of that site. I'd update periodically here, but host over there

there you will have more of these build threads including Duane's transformation from a Blackhawk pilot into a respectful man
oops, started day dreamin' there! But his build of that 76 power wagon into the best in the world will show up there.

I will be building other vehicles as well, and even get some of you knuckleheads to stop by and pull weeds all weekend in exchange for a rooe rack or something.

So the growth will not be happening here, although I will share here as well as at expo forums and perhaps some other places as well.

A bit of DOT activity before I hand the reins back over to Don:

Keep healing Don- in all seriousness, glad to see more cognizant verbiage flowing from the keyboard 

If Duane came over all work would stop. Atmospheric conditions would not favor the particular molecular makeup of my sockets or something insignificant like that.
Duane is so particular and has standards so high that work is seldom or ever produced. The forethought that went into the project, however would have maxed out the Pentagon's Cray computers.
One day he was checking his own work, I heard it said...
He was checking to ensure the break away torque of the bolts he had just torqued was perfect. He allows the lockdown torque plus or minus seven millionths of an ounce.
As the story goes, one offending bolt in a hyper-critically stressed part did not break within the gracious .000000000007 of an ounce. That part, the vinyl steering shaft cover if memory serves me correctly, was improperly secured!
Blasphemy!
Out came the holy oil, incense, and much gnashing of teeth!
Afterwards he took the appropriate corrective action which started, of course with discarding of the bolt, the vinyl trim, the steering column, and indeed the entire vehicle! Next I believe he set fire to the garage, spread the ashes, salted the ground, and sold the property!
I stopped him on the way to the church where he was going to enter the priesthood and run out his days in silent meditation of his immense failure.
We barely saved him from that one, and I can only hope we never see anything like that happen again!

                                                                                   (8462)
Got some new projects in queue for Combat max.

I want to add on a roof rack now, then really beef up the front end so the truck can punch through heavy stuff unscathed.
I'm thinking it needs two 3/8" thick steel uprights and then some tubular cross bracing that wraps back around the headlights.
Then add in some steel cables from the corners near the headlights up to the roof rack and those should direct debris and branches away from damaging the windshield.

I thought about integrating a hi-lift jack, shovel and axe into the front structure, as in bury it in the steel so that it is protected if the truck punches through a wall, but also provides secondary protection from branches, boards and debris from getting to the radiator, intercooler, and other coolers.

Right now, I am no longer settled with adding the Dana 60 to the front. The existing front suspension is robust and frankly, working well. No decision here, but when Square D gets up on it's feet and I can evaluate a Dana 60 front on longer springs, I'll have a good comparison.

I still definitely see a mechanical fuel injection 12 valve Cummins under the hood somewhere down track...without that swap, the truck will not be useable following an EMP event. So until I figure out how to harden all these delicate electronics, I'll inevitably go down that road.

The truck does not have many miles still, only mid 40's (K), but is running very well. The only problem it has had is blowing the hot end IC pipe off the turbo outlet many times now, at pressures above mid 20's. Admittedly, that is a problem and the only remedy I ever came up with that works has been to liberally clean both boot and pipe and turbo with brake cleaner, then spray adhesive into the silicone coupling, then clamp it all back in place.

So far, that has been good, but I have definitely kept my foot out of it, even when towing.

All this new stuff will show up in detail on the new web site and appear here in a one or two pic readers digest version.

Wow!

Great job Ken!

Ladies and gents, Ken has finally and successfully transferred thousands of posts from the web site where they were first penned to their final resting place, here at Real Man. He is finished the historical phase of C-Max, or Combat-Max the present name for the big Chevy. From now on it's up to me to push that truck in the direction I want it to go. The emphasis is obviously on Square D as we endeavor to get the axle back under the front end and get that power plant reinstalled.

OK, so at this point, the historical part of this build is complete with part 3

The continued build/life of the C-Max project will be continued in part 3. So with the addition of a couple DOT comments, I'll sticky this Part 3 and in the near future open up Part 4.
