What is the name of panel of rotary switches that direct air to the cab, suspension?

[Guyfang]

That NSN is not listed in that TM.

Then look up NSN 4730-01-527-8543. See what UOC is listed next to it.

Haha, we're going around in circles. Look it up in... what? The TMs we have are for OUR trucks. We already know this part is not for OUR trucks. It's for some OTHER mystery trucks. The guess is the late model FMTVs with the full armor cabs but we don't have those TMs. I don't even know if they are released or not.

 

[Guyfang]

TRK CG 5T 6X6 MTV W/E NSN 2320-01-447-3889 is what I found for this part you are looking for.

That get you any closer?

 

[aleigh]

That just heightens the mystery, actually. That's the LVAD, but it has air springs and a soft skin cab just like the rest, at least originally. My theory depends on them having a FMTV variant which doesn't have airbags, since the switch for them is missing on that part. Shrug. Who knows? Thanks for looking.

 

[Suprman]

I think some of the uparmored vehicles dont have the cab air lift.

The explanation for the UOC is on Page, (PDF reader page number) 19.
Look at the cover of the TM. Find your NSN.
Look to the left, thats your truck.
Go to page 19, and you will find this list below.

Code Used On

Trk, Car., LMTV M1078
UOC: LWB *W/WN
UOC: LAB W/O WN


Trk, Van, LMTV M1079
UOC: LWD *W/WN
UOC: LAD W/O WN


UOC: LAA Trk, Chas, LMTV M1080


Trk, Car., LMTV/AIRDROP M1081
UOC: LWC *W/WN
UOC: LAC W/O WN


* = With PTO.

The listing below is an example. Lets look at the wire harnes (part number 12420887) listed below. Notic the UOC listed at the end of the part listing. That wire harnes ONLY fits a UOC LAD and LWD. Look at the llist above, and you will see what trucks it fits. The wire harnes fits: LMTV 1079, WO/WN and the LMTV 1079, *W/WN. The astric means the truck has a PTO.

Was this any help? Look the parts up you need, and see what UOC fits your truck.

What are LACs, LADs, LWD, and LWCs? Sorry, I'm not familiar.

I think some of the uparmored vehicles dont have the cab air lift.

LTAS cabs don't have an air powered hydraulic system. It is driven by an electric hydraulic pump.

Do those lift rams you are selling require a retrofit to work on an LMTV?

Working on the manifold



So I am diving into the manifold. Looks like another PITA. It appears that the manual pump is made by PowerPacker and is still being made for non-military applications. The middle picture is on one of the screens I removed from the top of the manifold. They appear smashed. Anyone have a source for these? I see the name Vickers on the knobs of the manifold. Did they make the entire manifold, or just the valves? I tried to get the orifice filter out (it looked dirty) with no luck. Any recommendations as to how to get the orifice filter out of the valve body?

They are the UOC codes. Each model truck gets a code. When ever there is a difference between models, the code is placed next to the part. This way you can tell, for example, if the truck TM shows a valve, and there are 4 different valves listed for that item number, which truck model gets which valve.

Can you tell us what the corresponding truck is with theses names (LACs, LADs, LWD, and LWCs) ?

Parker makes the valves. You want my advice, take the whole thing to a hydro shop that works on cranes (I went the Seattle crab boat route, on the docks), dump it on their counter, and smile a smile, and just let them sort it out. You find the right guy in the back, he'll see it as a mystery or puzzle to solve. If you take them the TM -20P with the original mfr parts that helps them, and they'll call Parker and Parker will figure it out to the commercial parts. Or just buy another one.

PS - the internals of the valves are "cartridges". If you go to the parker website and get the PDFs you can actually run it down. The cartridges have a body style (the physical package) and then a series of characteristics like the working pressures. You can reverse engineer the military part numbers for commercial equivalents in the same cartridge series... You'll see.

 

[Guyfang]

Sure, BUT, you need the right TM.

What I mean is that if you look at post #39, and read the TM example I gave you, you know what part fits what truck in any given parts TM. The UOC code is NOT vehicle unique. It is TM unique. It is purely intended to show you what part fits what model truck in a given manual. That's important when one manual is used cover more then one truck. Some manuals cover 2,3,4, or more different versions of the same basic vehicle.

 

[Crapgame]

1994 M1081 LVAD, all the rotating knobs on the hydraulic control manifold are missing, and the manifold itself is just hanging there by hose tension, not bolted to the Tool Box. Also missing the swing down cover/hinge.

Is it going to be easier to replace the cartridge valves themselves or to buy a whole manifold then changeover all the lines? I'd prefer to just release the pressure then just change out the cartridge valves along with the metal data plate that is missing.

The ebay Manifold Data Plate I bought is taller and wider than the manifold, and the bolt holes aren't lining up anyway.

 

[Suprman]

There are 2 versions of the manifold. The parts tm shows both. I have good used manifolds if you need one.

 

[blackforest]

Suprman, I need a manifold and the back up hand pump that sits next to it. What is my next step to get them from you?

 

[Guyfang]

Send him a PM.
