Maintenance Management…Got MSD Questions? Get Answers!

Many of you know by now that the maintenance support device (MSD)-V2 is phasing out and the MSD-V3 is being fielded.

Here’s more info on these changes, and how and where to get support for your MSD or related equipment.


Some MSD-V2s are no longer supported by the manufacturer, VT Miltope. They can’t be upgraded to the Windows 7 operating system (OS), which is necessary to run new software updates and the latest interactive electronic technical manuals (IETMs). This makes them NMC.

Here’s how to identify unserviceable MSD-V2 models. Obsolete versions:

  • are missing the silver “VT Miltope” tag on the bottom of the screen bezel.
  • are PN 714000.
  • have a mother board serial number that ends in 855 or lower.

For the MSD-V2s that aren’t obsolete and still in service, the only solution to no Windows 7 OS support is to wait for the Windows 7 update release, expected in December 2015.

There’s an official letter of instruction (LOI) with guidance for turning in MSDs. The LOI is located on the PD TMDE website at:

  • Click the green text Login to MSD Homepage and log in with your CAC email certificate
  • Click the Customer Support Portal link
  • Click Technical Bulletins and download the May 2015 LOI.


The fielding of MSD-V3 continues, but there aren’t enough available for every unit.

Some units need to keep MSD-V2s for mission support. However, the LOI notes that keeping MSD-V2s on the property book means that your unit may not get replacement MSD-V3s when they’re available.

M119A3 Towed Howitzer… Power Cable Design Changed

The 8W0 cable assembly, NSN 5995-01-604-0451, is an important component that connects the M119A3 towed howitzer’s fire control computer (FCC) to the artillery power distribution assembly (APDA).

The cable now has a new design, so it looks a little different from the old cable. Which cable you get when you order a replacement depends on what’s available in supply.

8WO Cable

But don’t let that throw you. Both cables work just the same and there’s no difference in how the cables are installed or removed.

Crewmen and mechanics, the 8W0 cable is shown as Item 3 in Fig 1 of TM 9-1015-260-24 (May 13 w/Ch 1, Jan 15). If you get a new cable you think is bad, follow the troubleshooting procedures in the -24 TM.

If the cable is bad, file a product quality deficiency report (PQDR). File PQDRs through the product data reporting and evaluation program (PDREP). Access PDREP at:

M12 Fuel Lines Changing

The next time your M12A1 decon needs new return fuel lines, don’t go by the procedure in WP 0047 of TM 3-4230-237-23&P. The procedure for installing the fuel lines and the fuel line NSNs have changed.

Here’s what you need:

  • Fuel return line-injector, NSN 4720-01-628-0099
  • Fuel return line-pump, NSN 4720-01-628-0092
  • Banjo bolt, NSN 4730-01-630-1621
  • Valve cover gasket, NSN 5330-15-001-8495
  • Machine screw, NSN 5305-01-593-7762
  • Flat washer, NSN 5310-01-508-3313
  • Flat washer, NSN 5330-01-593-7760

To see the new fuel return line removal and installation instructions, go to:

Under Protection in the left-hand column, click on M12A1 Power Driven Decontaminating Apparatus. The click on M12 Fuel Return Line Training.ppt.

If your M12A1 return fuel lines are working, leave them alone. These NSNs and this procedure are only for fuel lines that need to be replaced.

New M240L Short Barrel Parts Available

MWO 9-1005-313-23-4 replaces the M240L long barrel with a short barrel. Once your M240L has the short barrel, you’ll need these NSNs for replacement parts:



NSN 1005-


Barrel assembly


Flash hider


Carrying handle


Catch barrel


Adapter barrel


Front sight assembly


Heat shield


Gas regulator


Erosion tool for M240L short barrel gas plug


Collar, gas regulator


Remember the short barrel takes the M26 BFA, NSN 1005-01-565-6693. It’s yellow.

The inspection criteria for the M240L with a short barrel is the same as what’s already in TM 9-1005-313-23&P.

M119A2/A3 Towed Howitzers… Retaining Clips Level Out Damage

Crewmen, treat your M119A2/A3 howitzer’s M187 panoramic telescope mount with care. That means hanging on to the retaining clips, NSN 5340-01-281-8295, that cover the level vials.

The sheet metal clips, shown as Item 24 in Fig 1 of TM 9-1240-404-24&P (Dec 10), protect the level vials from damage when the howitzer is towed and during airborne or air assault operations. But a lot of howitzers end up without the clips, leaving the level vials vulnerable to damage.

So save your unit money and protect the level vials from damage. Keep track of those retaining clips and, most importantly, use them!
