My next hot rodding project was a result is driving in light rain a couple of weeks ago. I kind of wished I had intermittent wipers in the light rain. I conducted some research and found modules intended for boats that looked like it could add intermittent wipers to a car, truck or boat. Modules...

Hello! I tried searching the TM and while they show how to R&R the three point seatbelt on the M998, they don't show what to do when it will not extend. I purchased a AM General Hmmwv Humvee Hummer H1 3 POINT SEAT BELT-REAR LH/RH-12480530-OEM-New and the packaging and label looked old and did...

I was just thinking, and could not come up with an answer... If one was to install a turbo on a M998 with a 6.2, how does one enrich the AF mix on a stock mechanical injection pump when boost is added? The other thing I was contemplating is installing the turbo below near the exhaust as the...

I did do quite a bit of searching and thought I would ask here since I may have over looked the obvious. Is there a Roof Rack specifically designed to fit a Helmet Top? Or should I just whip out the old tape measure and look for a Roof Rack that will dimensional fit the helmet top real...

Ok, I screwed up (again).I should have taken pictures and I would not have these issues. I removed the starter and put it back, but now the starter seems to run when in the run position! It did not do this before I started, so I am fairly confident it is the wiring at the starter that I just...

Made this up based on the responses in this and other threads. I'll come back and update periodically, so if you have updates, please reply to this thread with the status of your state. Updated: 11/10/2025 ME- Unfriendly Updated: 8/06/2025 ND- Friendly Updated: 5/23/2025 NH- Friendly Updated...

I'll try to make a long story short. I had a Freon leak so I needed to replace the condenser and recharge. I got the new condenser plumbed in but I still have to fab up some new brackets as the replacement was just a bit wider than the original for some reason. I wanted to charge the system...

I replaced my belts yesterday and I was going to buy another set to have on hand. The PS and Generator sets are easy. But I have an aftermarket AC kit installed. The AC belt that came in the kit is marked "15440", no manufacturer printed on it. The instructions state included was a belt "7440"...

I was watching the news and saw the Taliban parade our equipment. Many of the HMMWV, trucks and other rolling thunder had white wall tires? Here is one picture I found. Maybe they just painted them on. Looks like they also did some pin stripping on some of the vehicles too! Please tell me...

Hello, The four X-Doors I have a some de-lamination. I have been doing some searching, and it seems that the least costly source for replacement glass to solve the de-lamination issues for all four X-Doors is Federal Military Parts. A set of four Grey Tinted Unframed Replacement Glass Windows...

Just looking for any members in Central Florida that might be able to recommend a shop to change out stuck and broken glow plugs in a 6.2 Detroit Diesel? Not many shops are willing to work on Humvees :(

Again looking for advice from the collective. As I put in a post previously, I made the mistake of attempting to change out my glow plugs myself. One head had one that was rusted to the treads and would no budge with a breaker bar and rounded off the head. Another on the other head actually...

Was busy today trying to replace all the glow plugs as a maintenance item. Got busy on the pass side, cylinders 8 & 6 went smooth. Cylinder 4 was seized. The officer I bought the M998 from said he replaced all the glow plugs, but #4 was a different shade and I think he never did #4 as he did...

Hello once again. I tried searching. I beg the collective for some more of your fine advice to help me avoid wasting tons of $ Before I upgraded to a 200 AMP generator, the Wait Light did not light for the last couple months. I would wait a minute after turning to run and the truck would start...

Hi there. Another opportunity for you guys to mock me. I am planning on installing a rear winch. I have the m998 WINCH MOUNTING PLATE 12469385 REAR 5340-01-485-5962 I assume the rear lower a-arm bolt goes to the the yellow arrows. I don't have much of a shop, and I am old and feeble. I...

Hello, Once again I ask the collective for guidance on a question I came up with regarding upgrading a 60 AMP to 200 AMP gen. Please reference this YouTube: at the 16:30 mark. The creator references that there is a second cable supplied in the conversion kit that goes to the first battery...

I am hoarding parts for a 60 Amp to 200 Amp generator conversion and I need the knowledge of the collective again. This time, it is belt routing after the conversion. I bet there is someone here that has a 200 AMP generator with AC and can tell me how their v-belts route! A "Normal" M998 with...

Yet another request from the collective on a shortcut or procedures to help me save tearing up my hands, destroying my radiator, or breaking my fan. Once the Florida Inferno subsides in 5 months, I am going to replace all the V-Belts on my M998 6.2 NA and replace the Fan Clutch Host with one of...

Once again the NOOB must come to the collective to get advise. Recently, I began hearing a whistling noise that I have been unable to track down. At first I thought it was bad belt(s) or a bearing going out, but now I think it is something else. It sounds like a whistle to me. Maybe a vacuum...

Hello again folks. Another newbie question here. Possibly something I am concerned about for no reason, but I will ask anyway since is the first diesel engine I have owned. I understand it is possible, but not likely, that the 6.2 NA can run away under some unlikely conditions. So I am thinking...
