If there was water intrusion I would be most concerned about the valve body having corrosion issues, i.e. stuck valves. You could drop the pan and disassemble the valve body to see if it has been ruined by the water. That would be good to know before dropping it off if you go the route of...

Adventure Accessories shows the plunger in stock: https://adv4x4.com/5740647.html If you go to "Fuel system parts" on the website, they have a part 5742445 that looks like the plug, but it could be for the opposite side of the pump, in which case the hole would not go through. HPG has a...

It's not that bad of a job to replace the seal, and a lot less expensive, if that matters. I would consider it if the pump is otherwise operating OK. See thread "Weepy Injection Pump". You would want to make sure it is actually the advance plunger leaking and not the front shaft seal (which...

In post #3 (page 1 of this thread), point #1, I described a goal of keeping all of the modifications within the box, i.e. no modifications to the vehicle wiring harness, so that the box could be easily moved from one vehicle to another and provide identical function. In point #3, I described...

Thinking about the ballooning problem, I looked around on the internet a bit and found a few examples of CV boots equipped with anti-ballooning rings. Some pictures and a file with links:

MIL-STD-1180B was updated in 1991. You can find it by search: MIL-STD-1180B August 1991. Subscription service techstreet.com shows the 1991 revision but not any others; as far as I know the 1991 revision is the latest. I came across the attached timeline for the introduction of FMVSS...

Under Technical Manuals, Present Conflict Vehicles TMs, look for TB 9-2320-335-13&P Hmmwv M1151A1, M1152A1, M1165A1 May 2008. See Section 4-14.1, Section 4-17.1 and Wiring Chart FO-16 (3 pages up from the last page).

Look on forums.g503.com, thread: "electronic speedo cable"

Mogman, that's an interesting problem where the bellows balloon at high speed and are damaged. It is common for bellows expansion joints as used on chemical process/refinery equipment to have reinforcing rings to withstand higher pressure. Maybe you could equip your joints with reinforcing...

That's a good point about the 7K axles having the pressed-on retainers (maybe even welded on?) I haven't seen too many 7K axles, but I did replace at least one boot on one. In thread "CV BOOT INSTALLATION" I posted a picture of the NAPA 6862110 silicone boot on an outer 7K joint. This boot...

The Autozone axles are listed in thread "CV BOOT INSTALLATION". Another thread with a lot of good information is "HMMWV Half Shafts".

Also, you can look at thread "CV boot on HMMWV" for discussion about replacement boots. Include the quotes when you do a search.

I have had a parasitic draw within the light switch also.

Yes, I've done it on "rat rod" projects where expectations are not necessarily real high. I would be looking to see if the filter is intact, the filtered side of the transmission is free of debris, siphon out the fluid from the TC and see if stuff settles out or is visible in it. Also consider...

AAMVA ran member surveys on “Humvees” in 2018 and 2020. The surveys closed on July 10, 2018 and December 2, 2020. Each survey was linked in the AAMVA The Week in Review during the month before the survey closed. The weekly newsletters are public and can be found at AAMVA - The Week In Review...

I have a Melton rebuild here with the red paint on the lower end bolts, came out of Albany in a M1045A2. Sent from my E6910 using Tapatalk

It is possible to change the advance plunger seal with the pump in place. The metal part that passes through the seal can get rusty from water sitting in the valley, so it is good to change that also especially if it is in bad shape. Another possible leak point is the drive (input) shaft seal...

Purple Power is especially good for removing oily films because it contains ethylene glycol monobutyl ether. Glycol ethers as a group are good for degreasing because they combine characteristics of alcohols and organics, i.e. solubility in water plus ability to solubilize oils... I use it quite...

Are you going to do the overhaul yourself? I usually do the teardown first to see what it needs, then go shopping once. You might have a local store that serves local trans shops that has the parts on the shelf (here near Louisville we have Whatever It Takes, great to deal with.) I would not...

I recently had a vibration with a 6.5 in a M1045A2 and the outer ring on the harmonic balancer was visibly wobbling. Take a look with it running and see if it's running true. You might see also that the rubber is degraded. Not hard to replace... I also had another 6.5 with a vibration like you...
