I'm guessing you're smart enough to figure out what a 7 gallon oil change costs without asking. I interpret "cost of maintenance" to mean "cost to keep the truck in operational condition". The cost of performing the routine maintenance that the manual prescribes (e.g. oil change, grease some...

This is probably why you only see people around these forums for a year or two. They get an FMTV, but can't keep up with the persistent costs and man hours. So the first year they are all gung ho, but then it wears them out and they sell the truck off. You see dozens and dozens of "I'm...

This question has been asked and answered a lot of times, so I've had practice. ;-) And I'm not trying to dissuade anyone from getting an FMTV by saying "If you have to ask, you can't afford it". It's just a true statement. Because these are expensive trucks, and likely to have something...

The biggest issues impacting the cost of maintenance for an LMTV are that... These are 20 year old trucks, so anything plastic/rubber is slowly failing. It usually doesn't stop you dead in your tracks, but every couple months there is something else leaking that needs to be fixed. These are...

Probably, but I'm not sure there would be much mechanical benefit, especially over greasing them. Graphite powder can be mixed in as a filler to the polyurethane liquid. I've done this with other filler minerals, on other projects, for other reasons. I'm guessing you would have to add quite a...

That's awesome. I have a few similar young kids that work for me, but they are very hard to find.

The redundancy argument is a never ending one. Yes, you could just carry two of everything... except that you can't. So, personally, I want multi function tools that I can use to solve a multitude of problems.

That sounds like a complex solution to a simple and unlikely problem. I would carry a spare fuel line (all 3 are the same fittings, so make one to match the longest) before I would go installing pumps.

How would the system be under pressure? On these engines the injectors are the fuel pumps... they draw fuel to the engine from the tank. The lines aren't pressurized.

Thanks. I did end up using the primer pump button, but didn't think that was right. That's what I get for doing it in the dark. For those that want to see, here is a picture of the instructions on the pump button.

Do the liquids flow out freely? When I open mine, some seems to drain out and then it stops because no air can get in. In order to drain the rest, I have to unscrew the knob a lot, until air can sneak in past the threads. Is that how it's designed to work?

Another question... when draining the water separator, does it stop draining automatically once the water is out? It seems like when I open the drain knob, some liquid comes out, but to totally drain it I have to unscrew further it until air can get past on the threads. How is it supposed to work?

All the fluid capacities are listed in my parts spreadsheet, here in my signature.

The winch tank is oversized (and overkill, like everything else on these trucks). For comparison, HMMWV's just use the power steering pump fluid, without issues. In wondering why it is oversized, my best guess is that it's because that much fluid weighs almost the same amount as the winch does.

There are some on eBay. It's always a good place to look first, though usually a bit more expensive for the convenience.

Be sure to read the guide here in my signature. You've had several questions that are answered in there, such as rebuilding the hydraulic pump. (At this moment, the CTIS post is being rewritten, but it will be ironed out soon.)

Wow, those old ones look like they are carved out of canned dog food.

Interesting find. Where is that from? I'd like to read the rest. I don't think that's my problem. I use green coolant. I haven't put an in, but with the small amount of water I'm getting in the fuel, I probably wouldn't notice from such a huge cooling system. Similarly, if I pumped the...

If you need them, I just added the line dimensions to my parts spreadsheet, because I just had mine made and replaced them.
