What have you done to your HMMWV today/lately

[Coug]

Lately it has seemed like my truck has been missing at high rpms/heavy load. Took the BEOD off the back (2500 lbs)and drove it again, still sounding like it's missing at high speed/load, and doesn't want to go over 60mph.

Decided to check the fuel in the filter, so opened the valve by the front wheel and nothing came out while truck was cranking or running. Soon afterwards the engine stumbled and died.

I am assuming that the fuel lift pump has died and the injection pump just couldn't suck enough fuel under heavy load, so I have a pump on order. Any chance I screwed up and it's not the lift pump? (sounds great at idle and low speed)

The lift pump is dead. You would especially notice lack of power and slowing down when going up a large hill. I replaced mine, then the filter, and it was like a new motor ! If the diaphragm failed, it may clog up the filter.

If one searches in this forum in simple words of your problems... it will show up and give you something to go on. Recurring problem week after week. LOL

And the little things that mess up in your tank
Been there done that too, CAMO

Replaced RR spring on M998. RR was a tad fatigued. LR is next.

1750# springs before/afterwards. New plow springs are a great deal.

Yeah.
I had my tank dropped and checked it all out when I first bought the rig, it was clean inside. I dropped it because of a hole someone drilled/manufactured in the top of the tank that leaked when it was full.
Fuel comes from the same sources as my car (VW TDI) and it's never shown any water or dirt in the filter, so by process of elimination it either needed to be the fuel pump failed, or perhaps I had overlooked something.
As you said, it shows up time after time in this forum, so no need to do my own or hijack someone else's unless something different comes up.

Spring cleaning.

Found a brandy new wiper motor. Found not one but two sets of Airlift bumper installation brackets. Relocated Extra injection pump, Three military huge fairleads, Four spare halfsgafts, Pintle extension, and my brand new 24V 12 ton spare winch for the rear of the vehicle.

Now all are placed neatly in labeled boxes in my storage room.

Hooray for Spring.

The humvee brought the hamster out of me too!

Now I just need to paint it the right color .

Did some maintenance on the truck. Finally got around to changing the front boots on the ball joints. They were ok on uppers, but completely dead on lowers. Everything got new boots (energy suspension ones) On the passenger side, I adjusted the hub to line things up, and heard a clunk. I didn’t do the spring scale test, but that Idler arm looks a little too suspect. I bought new tie rods a while back, just in case, as the tie rod boots were beat up too, so tackling the tie rods next. The boot near the hub was just pulled off in the video, but nothing was really holding it. They didn’t seem to move, but that Idler sure did. Got that and some new cotter pins coming.

Clunk...

Just ordered all the bolts washers and nuts and spacers I need from Mac Motors to install my Airlift bumper and pintle extension and ratcheting spare tire carrier.

Looks like I just made my weekend plans.

Woo Hoo.

Id like a pintle extender. Cant pull my equipment trailer without one... or removing the spare.

I hope you aren't finding all that inside your truck!!

Really nice work. Would like to see more of how you accomplished that repair. Not that I plan to damage my truck but just in case.

Finished removing the remaining glow plugs and wouldn't you know the hardest to reach (#1 cylinder) was stuck. The Black Dog Customs removal tool worked as advertised although the tight work space made it challenging at first. Applied some anti-seize prior to installation, torqued to spec, and added a lil dab of dielectric grease to the boots for good measure. Started up nicely after a 7-8 sec Wait light. Voltage pulsed a few times over the next minute or so before settling into the green range.

After ordering some rigid molle panels and being disappointed in the high price of plastic sheets with holes, I decided to see if I could make a small one to fit on top of my ac unit. Using one of those expensive panels as a jig and a 6 dollar piece of hdpe I managed to make one with only a few mistakes and didn't quite destroy the original. Anyway, the pouches cover the mistakes and it works as intended. And I learned you can make a nice flat finish with 220 grit and an orbital sander.

Made a bracket and rerouted a cooling line to add this 24v alternator to the Duramax. Hope to purchase batteries soon and rig up a 24v system so my AC will work along with heater blower motor and a couple other things.

You Marines out there will remember these iso sleeping mats. I used a few of them, some mirror trim and spray adhesive to insulate the hardtop. And added another rigid molle panel.

Broke in my new Milwaukee high torque impact wrench.

Rust here by the ocean is significant. This device made removal of the front bumper effortless.

That is an excellent idea. I was wondering what I could use to insulate my 1045A2. Now I know, thanks. Did you use headliner spray adhesive or what?
