Possibly. 47" -> 52" is about a 10% change in MPH, so that would get you to about 64MPH.

The 3.07 gears are a 20% change, so you get 20% more speed, and 20% less acceleration and pulling power. This puts 65MPH comfortably low in the RPM range, right after the shift up to 7th gear, and makes for nice cruising. 65MPH feels like less of an obstruction to traffic, and it's nice to be...

If you make them, please share.

They look like LMTV axles, or very close relatives. I think what he was saying was they came off an LMTV, hub gearing was removed, and were destined for a truck that weighed 1/2 as much as an LMTV. If you weld the planets, you put all the torque directly on the axle shafts, and they were only...

Why don't you go look at the manuals' diagrams, or watch a YouTube video about these axles? This really isn't a great idea, under all but the most unusual of circumstances.

There should be nothing inside it. It's just a block that connects the splines of the shaft, to the hub flange. That's what you're asking about doing, right?

This, and it reduces the forces in the axles (e.g. reducing the diameter of axle shafts needed, etc.).

Just google "LMTV boot".

I don't know, but have you looked at the wiring diagrams in the back of the TMs? They list the tag numbers for everything, so you should be able to find it. You might even be able to do a text search in the PDF for it (not entirely sure it will work, but worth a try).

There's no brace, and all the trucks got the "D" modification. This topic still goes round and round, after all these years. Read the section in my "Common Issues & Fixes" document here in my signature. It compiles all the useful info on the topic (and others), without having to read through...

The inside of the metal cover for the fuse panel should have a diagram of all the locations, and the manuals detail each slot (though in a couple of different places that have to be read together to develop a complete picture).

Thanks Reworked! If you have any measurements and pictures of where the hole gets drilled on the M1088, I can see if I can include them in the instructions. I try to make it "so easy, a caveman could do it", but there are admittedly some variations between the different truck models.

I'm just pointing it out, because there are several members, who have been around for a long time, that swear they get 10-12MPG. It gets everyone's hopes up, and then we get a bunch of new people in here with unrealistic expectations. The topic comes up periodically. I recently had a guy tell...

My mistake, it is a 26kW (35HP) fan. This military study is where I got the number from. It also talks about the airflow requirements, stating that the "current M1078 cooling fan system required air flow of approximately 8000 to 15000 Cubic Feet per Minute (CFM) (226 to 425 m3/minute)". NOTE...

Yes, absolutely. The difference in military and civilian design is that for the military you must meet their specifications under all (extreme) conditions, and for the civilian market it only needs to be able to do it under ideal laboratory conditions. These trucks all use the same cooling...

I have a few thoughts... You can pick up the military fans, both old and new style, for <$150 surplus. I'm not too concerned about a NOS fan, as it's made out of hard plastic and metal, so age shouldn't really affect it much. The military fan is special because it moves a TON of air...

Thank you for pointing that out to everyone. This is the difference between what you and I are saying, and what I want people who read this thread in the future to get out of it. I'm making it clear my ideas are just speculation, and you're portraying your opinions as facts.

Unless you have really deep pockets, you almost have to work on the truck yourself. While nothing is particularly complex on these trucks, it does seem to me like everything takes 2-3x as long as it would on a pickup, perhaps just because of the size. I do it all myself, but one time I was in...

I didn't say I loved it. I'm just saying your theory is shallow. And I don't want newcomers to think there is actually some history or evidence behind it. There are many equally-good reasons they changed the fan. Maybe they needed to change the clutch to a larger one, that no longer fit the...
