Fording Project

[rustystud]

You know what you're doing, rustystud. Wow!

Sometimes the simplest solution is the hardest one to come up with, and you ALWAYS go right TO it:

- Impressive. Really impressive.

Your thread here is its own stand-alone sticky on how it's done. Nice.

Thanks Ahab ! I appreciate the support!

Dang you up early this morning Rusty. I know you can cut that tank open and put in a cool baffle system if there is ever a problem.

I'm up late sometimes when the pain won't let me sleep. Such is life.

 

[Another Ahab]

I'm sorry that you got that to deal with.

But yeah, like you said; what you going to do? It's just the way it goes.

You can try complaining, but then everybody leaves, and that's no fun.

You got that right Ahab ! "Pity parties" are by their nature a party of one !

Thread brings back old memories of a fun project.
Yours truly actually dug his own "fording pit" because there were so few opportunities to test the finished kit.
A couple of images.


Because the brake drums are not pressurized, an "after fording service" will be required, where everything will need to be inspected...a good reason to avoid driving in water more than a foot deep, actually. I learned a lot from that experience.

Building your own fording pit, now that is "Hard Core" !!!!

Project generated two articles published in the Military Vehicles Magazine.

That is one GOOD looking rig you got there, cranetruck.

Do you have a stand-alone thread on here somewhere about it? Because I really need to check it out if you do.

 

[cranetruck]

Thanks, yes a very useful combination and there are hundreds, perhaps a thousand posts related to it going back over 15+ years on this forum and some 20 articles in Military Vehicles Magazine related to it, not really a "stand alone" thread on the truck itself, I don't think.
Lots of stuff related to fording, not to get sidetracked here.

Side track by all means ! I would love to see more of this and I'm sure other members would too !

Fine, here was my permanent solution to the crankcase breather "problem" when fording. The idea was to make the truck as fording ready as possible.



The breather fumes are filtered and returned to the air intake (ignore the DVM, it was part of a non-related experiment) . The "Crankvent" filter has a sump for draining oil at intervals determined by how much the vehicle was used.

More fording related details.



Compressor air intake is permanently connected to the engine air filter canister.
A selector valve (not shown) is manually operated to select pressurization of components or not. When not pressurized, components are vented high on the firewall via copper tubing as shown. Regulator cover off for non-related measurements.

Measuring your intake temps?

 

[cranetruck]

Measuring your intake temps?

Yes, compared it to temp at intake manifold, where a second thermocouple was installed to show slight intercooler effect (difference was only about ten degrees F). The intake manifold is double walled to help warm intake air when engine coolant is heated by fuel burning coolant heater ("arctic kit).

How did you pressurize your system ? and where did you get that manual valve ? Pictures please !

 

[cranetruck]

The original pressure regulator looks like this in the TMs.


My truck came from the USMC and had this regulator factory installed.
The control valve is item 28 in the picture and is operated via the "Fording T-handle" on the passenger side of the dash. I'll look for pictures.

 

[rustystud]

So you had a "factory" set-up correct ? Do you know what that regulator was set at ?

 

[cranetruck]

I have permission to reproduce the MVM article here, so here you go (including a picture of the fording handle). Don't have it in pdf format, sorry.

 

[cranetruck]

The "factory adjusted" pressure on my xm757 is 2-1/4 psi.

 

[daytonatrbo]

Here's a photo of the remote valve on my m109. I'll see if I have pics of the dash.
