With all the posts on the Deuce Mod Board about the multi's oil filters, I thought it interesting that the Mack motor in the new tractor uses only one of the same elements for the primary full flow filter and the secondary bypass flow element is the same as the big gasser. Obviously the...

I have what I think is a good suggestion for trucks that have been idle for an extended period (learned the hard way!). As we all know, insects and rodents seem to gravitate towards the green iron, and will take up residence within minutes (it appears) of shut down. The new tractor had...

New (to us) truck just delivered on Tuesday. Looks about how I expected. Data plates are not too good, and no maker listed or date. Any help on date and maker?

We have owned our H2O truck since October 2005, and finally got it ready to run and road worthy last fall. When I tried to register it (no title, only a hand written bill of sale), I could only get a weight rating of 18,000 pounds, as it had never had a title, and since it has three axles the...

I know that the 5 ton was first designed around the 602 gasser by mostly IHC, but how late was this engine used in new trucks? Our H2O truck is a 1961 (per data plates) and was just wondering when the switch was made, and was it made all at once, to the Macks or over time until the multis came...

Anyone know why, in their infinite wisdom, the Army decided to use the slightly tuned-up multi in the 5 tons instead of the ENDT-673 Mack, which had already proven itself in the early '60s? From what I've read, and what others have added through this site, the multi was hard pressed running a...

Could anyone please list the WIX/NAPA/Hastings filter numbers for the ENDT-673 engine used in the A1 trucks. Just won a tractor on e-bay, and I am sure that the filters will need to be changed. Expect to need air, both fuel, and both oil sets. Also, anyone had any experience with these trucks...

I have run a search on this topic, but still don't have a very good picture of the solution, except for a full replacement of the transfer case. Could it be as simple as an adjustment in the linkage? Are there detent balls/springs on the shifter rods? Bad/dirty oil causing who knows what for...

Photos of right side can holder. The blueprint does reference a de-con unit use.

Added some stencils to the H2O truck, but not real happy with how they look. Tough to get the stencil to stay flat on the panel so the spray paint won't fog around the letters. Picture of solar charger mounted on flasher pipe and two photos of the gas can mounts (with one German made can!)...

Finally got the last two spray heads installed on the truck this weekend. Only had the front two installed last fall to try out the system before we invested in the others. Filled the truck half full and ran up and down the street running the heads, neighbors were real impressed! Pump won't...

Since this question has come up a few times, I decided to get some pictures showing how the spacers work on the bridge truck axles (with the hubs flipped). Sunday I took one of the old tire/wheel assemblies apart since it had a slow leak anyway to show the real deep offset that the bridge truck...

Anyone got pictures of a bobbed 5 ton that they have done? Have seen a lot of pictures of deuces that have been cut, but the 5 tons seem to be more scarce. thinking about cutting a spare M139 w/gasser and front winch, and adding 1600x20 tires. Would use the front springs and mounts from...

We have never been real happy with how the water truck goes on the road. It never got up and went, like others have described on the site. Since it was in the high 30s and 40s on Saturday, I made a jumper for the spark plug and decided to check the timing. The original distributor was broken...

Why does the site time out for my pass word if I take too long (5 minutes or so) to write a responce to a Topic? Can I change this? Real problem if you get almost through a subject and go to post and you have the whole thing disappear. Thanks

Anyone know where to get carb kits for the replacement Zenith carbs issued during the '80s for the gasser 5 tons? Have one on the water truck, works great, and have a spare, but would like to have at least one spare parts/gasket kit on the shelf just in case. Had to steal the gov. diaphragm...

Any idea of the type of fuel used by the military? The reason for this question is that the fuel in the M812A1 looked like butterscotch pudding and smelled like a chemical factory with a slightly sweet alcohol smell. Didn't start good but ran OK and idled good. This stuff is at least 3 years...

Now that I have had the weekend to look over the truck, a number of small items/issues have come to light: 1) The entire hot start flame heater system is missing, with the intake just plugged off and the cab switches left in the panel, but disconnected. Any suggestions? or should we just...

Lowbed driver delivered new truck to the yard today. Went to Maine friday and picked up the truck, new drop side bed and 4 75% 1400x20 radial tires. All the stuff looks great so far. Already changed the oil & filter in the engine with Rotella 15-40 and WIX filter. Look at the pictures an let...

We only have two very small leaks on this truck, so a couple of questions on seals: 1) Can the rear seal on the transmision of a 5 ton be replaced without taking off the retainer plate? In the manual, it looks like you can remove the flange & slinger and remove the seal IF it will come out...
