M44-Series Truck Parts Cross-Reference

This page lists cross-reference data for some of the common expendable supplies and replacement parts used by the M44-series 2.5-ton 6x6 trucks with LD-465-* and LDT-465-* multifuel engines, such as the M35A2 cargo truck and the M109A3 shop van. This data may not be applicable to trucks with other engines (such as the OA-331 gasoline or LDS-427-* multifuel engines). I will update it occasionally as I find more information. Please let me know if you find any errors, or if you can provide any more information.

Filters

Note that filter elements are generally supplied as part of a kit which includes gaskets and seals which should be replaced with the filter. This table currently just lists the military part numbers for the filter elements by themselves, and I do not yet know if the cross-referenced replacement parts also include the required gaskets.

• The bold filter numbers are replacements which I have used, and which appear to be suitable replacements to me.

• The italicized numbers are replacement numbers which I was given, but which do not appear to be suitable replacements to me (see notes below).

Notes:

• Right = passenger side, left = driver side

• NSN = National Stock Number

• FSCM = Federal Supply Code for Manufacturer, as published in SB 708-42

• Listed part numbers are for filter elements only. Parts kits including filters, gaskets, etc. were supplied for some filter units.

• I ordered replacement primary and secondary fuel filter kits from Memphis Equipment Co. in November, 1999. I believe that all of the fuel filters I received were incorrect, and thus the cross-reference(s) for engine fuel filters listed above are suspect. The primary filter I received had end caps with a center bore of about one inch, and thus would not necessarily be properly centered in the filter body, while the filter that came with my truck (see pictures below) had a much smaller hole in the middle, sized to fit around the shaft in the center of the filter body, surrounded by smaller holes to allow fuel to pass. The secondary filters which were installed in my truck had the correct military part numbers (according to my parts manual) stamped on them, and thus I believe that they are correct. The Wix filters which Memphis sent me had different gaskets on the ends; they were mounted by a rolled metal flange in their center hole, while the correct filters have gaskets mounted by a rolled metal flange around their outer edge. Thus, with the replacement filter, the cup at the bottom bears against the metal mounting, and the seal does nothing, while with the correct filter the cup would bear against the inner edge of the rubber seal. In addition, both types of filter kits included incorrect gaskets, seals and washers, thus reinforcing my belief that they are incorrect. The guy at Memphis states that they've been selling those for over 50 years; while the replacement filters can be inserted in the filter housings, I do not believe that they will properly filter the fuel because they will allow unfiltered fuel to bypass the ineffective seals, and thus jeopardize a very expensive engine. Seems to work is not good enough in my opinion! On the other hand, the Wix 51133 oil filters I got from Memphis do look like suitable replacements for the Fleetguard LF509N filters which came with my truck.

  Update: I've been told that a NAPA Gold 3311 filter is not an exact replacement for the primary fuel filter, but that it works. I'm told that its center holes are also larger than the ones in the original filter, so I think I'll just use NOS exact replacements as long as I can get them. I made those Wix 33512 filters work as secondary fuel filters by making gaskets to go between the inner bore and the spring-loaded metal cup at the bottom, since there would otherwise be a metal-to-metal contact there due to the Wix filter's different construction.

Fluids and Grease

Fluid/Grease Types

Fill Capacities

Notes:

• Unless your truck came right out of military service (like my first truck did), make sure that a previous owner did not top up or replace the brake fluid with ordinary DOT 3 or DOT 4 fluid before you add any DOT 5.

Hoses

Lamps

Notes:

• BO = blackout
• cp = candlepower
• T1-3/4, G-6, S-8 are bulb types
• NSN = National Stock Number
• FSCM = Federal Supply Code for Manufacturer, as published in SB 708-42
• Many of these replacement lamps are available from Bulb Direct

Miscellaneous

Tools

TP Tools carries the following tools which come in handy for working on a 2.5-ton truck:

• 6-ton jack stands: You'll need three pairs to lift up the whole truck (for example, to rotate the tires). The shipping is not cheap on these, but 6-ton jack stands aren't always easy to find locally.

• 3/4"-drive impact wrench: I haven't seen 1/2"-drive impact sockets big enough for the lug nuts (and a 1/2" impact wrench probably couldn't develop enough torque, anyway), so you'll need a 3/4"-drive impact wrench if you want to save your back. The truck has 60, yes, SIXTY lug nuts, and I sure wouldn't want to pull them all off with the regular lug wrench!

• 3/4"-drive shallow impact socket set: This set includes the 13/16" square socket you'll need for the inner lug nuts on the rear wheels.

• 3/4"-drive deep impact socket set: This set includes the deep 1-1/2" hex socket you'll need for the outer lug nuts on the rear wheels.

A 3/4"-drive impact extension would come in handy, but isn't absolutely necessary for the lug nuts. The wheel bearing gets in the way a bit, but the wrench and sockets listed above will still go onto the lugs at an acceptable angle. Don't bother with the engine stands or engine leveler that Tip carries; the LDT-465 engines are heavier than the ratings of the largest ones they carry. Buying all of the tools I listed above isn't cheap, but it makes working on the truck's wheels a lot easier.

The standard jack issued with the truck is an 8-ton hydraulic bottle jack. I picked up a 12-ton jack from Sears. You'll also need wood blocks to give the jack some more height (chunks of 2x6 work well). If you're going to lift up all six wheels, I recommend lifting the middle axle first, in order to have as many wheels as possible on the ground while you're underneath the truck pumping the jack. Give the truck plenty of room to bounce before it hits your head in case the jack fails! Better yet, convince somebody else to jack the truck up for you. :-)

	These are the filter replacements I received from Memphis Equipment Co.. From left to right: Soda can (for scale), primary fuel filter replacement kit, secondary/final fuel filter replacement kit (two required), oil filter replacement kit (two required). Please note that I believe that the fuel filters are not correct replacements for M44-series trucks, though they are similar and will fit into the filter housings... see above in the filters section.
	This is the primary engine fuel filter I removed from my truck (which I bought from DRMS, and thus it came straight out of military service). I believe that this is the correct filter, while the filter kit I ordered from Memphis Equipment Co. appears to be incorrect.
	Here's another view of the primary engine fuel filter I got from Memphis Equipment Co.. Note how the end cap differs significantly from the correct filter's end cap.
	Here's the end of one of the secondary engine fuel filter replacements I received from Memphis Equipment Co.. Note how the gasket is mounted with a rolled metal flange in its center. The correct filter (for which I do not yet have a picture) should have the gasket mounted at its outer edge, so that the cup at the bottom will bear against the inside edge of the gasket, rather than against the aluminum body of the filter element.
	Left middle wheel hub, disassembled to show wheel bearings.
	Curbside power entry connecter which is mounted on the front, upper right corner of the shop van's body.
	Another collector sent me these pictures of the connector that plugs into the curbside power entry connector.
	Still another collector sent me these scans of catalog pages listing the curbside power connector. Warning: these are big images!
