HMMWVs have a 6 digit serial number, H1s have a 17 digit VIN. Modifying the HMMWV serial to 17 digits is an illegal modification if not done by the government agency in charge of such things.

Looks like he went to install, then realized/remembered that it snapped it off during removal.

For automatic transmission use, DEX VI is 100% backwards compatible. Everything else should stick with DEX III (transfer case, power steering) Or just keep everything DEX III for simplicity sake.

If I had to I might run the engine, from dead cold, maybe 3-5 minutes at most. Probably wouldn't do it more than 1 minute if possible. Definitely wouldn't use much throttle. It might be safe for longer periods of time than that, but the fact is running it for 1 minute, then letting it cool for...

I probably should have mentioned the first picture is about 3 years after I painted it with RAPCO. I sprayed it using a cheaper power sprayer (wagner) and then touched up places with rattle cans after that dried. I spoke with Rapco a couple years ago when they changed suppliers for their...

One advantage of RAPCO is they sell rattle cans of paint as well as gallons, so it's pretty easy to touch it up later. CARC is a much tougher coating, so doesn't need touched up or fixed anywhere near as much as paint does. pictures probably won't show you what the colors look like in real...

The center drag link is thinner than the A2 version, so if you use the A2 idler and pitman arm you have to add a spacer (just a thick washer really) to the castle nuts to make up the extra length of the threads. Not sure the differences in the tie rods

If you take it somewhere to have an alignment done, they should have "H1" in their alignment rack computer system

Usually if you need both the ends and the shafts, it's easier to buy them as an assembly. Part numbers can be found on here for assemblies and individual parts (but not all are available right now) https://www.hummerpartsguy.com/TIE-RODS-RADIUS-RODS_c_965.html

There shouldn't be. For all intents and purposes, the M1097R1 series trucks are all standard HMMWVs of other variants that got upgraded for extra weight capacity. There really isn't anything special about them whatsoever, other than not following the standard serial numbers of the regular series.

1) maybe/probably 2) the seal should be fine under normal use, so either it's failed or something else has failed and caused the seal to fail. 3) not a good idea 4) it certainly won't hurt anything to replace the entire box. If you aren't comfortable doing tear down/inspection/repair, it's...

It probably wasn't that the 6.2 wasn't robust enough, but that they had already phased out the 6.2 and everything was getting the 6.5 as a replacement.

Same thing with the H-45 heaters and trying to relight them while they are still hot. First time I went to the field with my unit, one girl flash burned her eyeballs, as well as taking off her eyebrows.

no. You don't want to go backwards. The parts were updated for a reason.

I don't see why not. I've had a battery disconnect switch in my truck for 3 years now no issues It's not so much a "fix" as a workaround. Who knows how long it will continue to work in this manor, and it could decide to stop working entirely in a matter of weeks, or might work for many years

Was out driving some trails with friends. We stopped for lunch, then afterwards my truck showed the glow plugs, but everything went dead when I tried to crank it. No electrical anything working. Pulled the seat to get to the batteries, and the clamp on the ground side of the batteries had...

cold weather no start usually means either your glow plugs have failed, or your start box has. In theory it should already have a block heater installed, and all you need to do is add a power cable. Standard GM glow plug power cable.

it may or may not be an issue. There should still be fuel in the lines and filter, so you might find it fires right up with minimal cranking. When I dropped and reinstalled my tank I don't remember doing anything special to get it running again. If it does have issues, then yes, you'll need to...

I know this is an old thread, but wanted to update the PS magazine link posted earlier. They changed where/how the articles are posted, so the old link is no good. Here is a current/functional link https://www.ldac.army.mil/web2/archive/PS2001/588/588-06.pdf Also linked the PDF page that the...

this page has a pretty good list of filters for the H1. Most of them are the same as the HMMWV (except the fuel filter as mentioned above) http://www.hummerknowledgebase.com/parts/list/005.html
