thats crazy......

Maybe fore you go much further put a "run out gauge" (think that is proper term/tool) on the block and dial it to your crank end. slowly turn it and see if it turns w/out micro wobble? Or maybe just to check if the end of the crank is not milled funky.... that is such a weird perfect circle crack.
.
True. It looks more like some sort of casting mark.

Here is a couple shots of confirmed leak, inside and outside, thats at the mounting bolt for the pump/steering pump

If they are casting marks..glad the new one doesnt look like that

Checked runout or wobble, crank checks out almost perfect, nominal results.. That case is headed to the scrap heap aka, metal pile, in the future I may play around with the tig and mill and see how well it welds/machines

I am going to add the following..

ALL of this was preventable,
To start with the oil line of death failure, to the cracked case, to the never ending loose belts..

While I disassembled, I have found what I believe to be the root cause..

missing bolt in support bracket between compressor and steering pump to block (F157, I24), this allowed the assembly to vibrate, first breaking the oil line of death, then cracking the case. On the Alternator, the lower bolt (F100, I 41-43)was sheared off, and the alternator tab was resting on the bracket.

I am now done kicking myself in the ars, but want others to be informed/aware.. I highly recommend you check these two areas closely. All missing and broken hardware will be replaced with appropriate grade and application of appropriate Loctite.

Learn from my costly mistake..

She is going back together well.. and no surprises thus far

I got a surprise coming for the CTIS system from overseas.. should be here on the 18th. Looking forward to more control and flexibility from it :)

will report out on the results...

Making progress, rebuilt battery box, with 4/0 cable, terminal ends.. should be a marketable improvement. Also ran 4/0 from battery box to front grill for the 12000 warn

Humpty is going back together, valve train back in, oil/filter changed, power steering pump topped off..

Down to intercooler and radiator and coolant..hope to crank her up sunday

Aargh..

Tonight after a test driver, I developed a noise and smoke slight misfire, my thought about valve clearance is probably related to a stuck injector.. sounds like a hammering exhaust leak.

This video kind of covers the noise



looks like I need to pull the valve cover and look closely, hopefully its minor. frustrating, but not giving up

ok, I know what "it" is (a CTIS controller), but what makes it so special? and does it only work with LMTVs? Or also M35A3s?
home brewed by an Arduino enthusiast; member from here. Far as I know its only been tested on A0 and A1 FMTV's. If the OEM FMTV CTIS controller works fine on M35A3's would reason that this would also work on them..... but that is just a guess.

I needed a new CTIS wheel valve and I found a kit that goes to another MV but the valve itself is exactly the same for the FMTV's. The rest of the kit I didn't need.

So, if you need a CTIS wheel valve here it is in this kit.


Doing some searching of my own, found that kit for $58

Yeah, CTIS controller for LMTV. As it sits, it should work with any truck that uses the same Spicer controller as the LMTV. So if the M35's controller is interchangeable, so to would be this. Beyond that, you'd have to ask Plasa.

What makes it special is that it does everything that the OEM controller does and more. It has the same four modes but YOU can program the desired psi for each mode (ie: I run my Goodyears at 80psi in HYW). It's simple to program, too (open the lid, move the little jumper pin to the "settings" position, select the mode, select the psi, save and return the jumper to the "saved" position). It can also be updated with new software as Plasa makes any programming changes/improvements. It's built on the Aruino Nano platform (which is a tried and true time-tested little open-source project computer with a ton of support online).

The OEM controllers seem to fail at very low hours. Mine died before my A1R truck hit 10k miles (it was like new). NOS replacement can be pretty expensive (because supply/demand, junk yard costs, yada-yada,) and often get scalped for twice what Plasa sells this unit for. I knew I wasn't replacing my OEM for those reasons so it was a matter of sourcing the parts and a housing and building a manual controller...or purchasing this from Plasa (plug--n-play).

I still want to do a proper review but the last two times I was on the sand it was hard packed and no real reason to air down for pics.
