Just bought a CUCV for $625.

Why, Martin...why? :doah:



I'm second in line for the lights. One of mine is now broken.


The lights are for driving a stealthy convoy at night. If you get a line of these things going they can follow each other via these colored lights (instead of using the normal service lights). One of the 2 extra switches at bottom left of dashboard should allow you to choose between the normal service lights and these special "blackout lights." In both the "blackout" position and the "off" position, normal lights are disabled (that's why Kenny asked about the switch position).

There should also be a small blackout light inside that hole in the driver's side of the grill, and that would be operated with the second extra switch. It projects a faint light on the ground in front of the vehicle. That light, on a dark night, will allow you to move forward with a spotter, and it's just about invisible to anyone standing more than 10 feet away.

Pretty neat stuff. Not sure who has a use for them, unless you have a bunch of CUCV-owning friends, AND you like sneaking around at night (as if the rumble of a 6.2 isn't enough of a give-away). But they are a neat piece of military heritage. :thumb:

Blackout lights are only useful against enemies that do not have night vision capabilities.


Night Vision Goggles (NVG) enhance and amplify any light to make one able to see at night whether it be moonlight or any other kind of light. So, those rectangular lights emit a very small amount of light that make it nearly impossible if not difficult to see by the naked eye but under NVGs its amplified like someone turned on a flashlight. Those lights mixed with NVGs allows soldiers to drive at night with the appearance of having no lights on but under NVGs, its suppose to look like you have headlights on to allow you to see where you are going and to see other military vehicles in your convoy.

What we do today is take an offroad light and an IR (Infrared) cover on it. Too the eye, it looks like a tinted cover on a turned off light, but under NVGs, its like the heavens is opening up in front of your HUMMWV.
 
The round plate with the numbers is a bridge classification number. IE, what kind weight the bridge must be able to support in order to cross it. I think it's more for the mobile combat bridges.

About the swollen glow plug - take this with a grain of salt.

When I was in the Army and the GP controller in HMMWVs went out the GP would swell up like you have and not come out. After a couple hours of attempting to get the GPs out the mechanics would just break the ends off and stuff them down in the cylinders and install the new GPs. Then they would fire up the truck and blow the end out exhaust. It was a government vehicle so I never questioned it and never saw the tip get stuck in an exhaust valve. I have seen it done 3 or 4 times out in the field. Under normal situations they would have sent the truck to what is called 3rd shop and had them tear it down and remove the broken end.

Your mileage may vary. Good luck.
 
So you snapped the glow plugs off and just blew them out the exhaust? Do you think all the chunks came out? Also, just so I understand, this is only for swollen tips, right? You still need to be able to unscrew them. If you actually twisted the head off them you'd be SOL I think.

Correct.

I'm not sure what the GP look like in the 6.2 but the ones in the HMMWVs were kind of thin. They unscrewed them so all the threads were clear of the hole. Then they put vise grips on the flat surface where you'd put a socket or wrench and then just slowly bent them back and forth until the swollen end broke off. Then install a new plug and fire it up. You'd hear it tink a few times then blow out the exhaust.

When they showed me what a new GP for this motor looked like it was thin. Kind of the size of a pencil with threads on it and nut type surface to screw it in with. Then it had a connector on the end.

They would try for a few hours to unscrew them before doing this. I remember them putting the vise grips on the end and pulling while turning trying to get the swollen part to engage the threads on the head so they could unscrew them.

I don't know the shape of the GP for the 6.2 so this method may not work. :dunno:
 
That all makes sense. So far I've been unable to get them to unscrew (rotate) at all. They feel seized in, but I haven't tried on a hot motor yet.

You guys may have covered this, but what glow plugs do you like? Back when I was researching it, everyone was crazy for these self limiting ones they sell at Kennedy diesel.
 
AC 60G's are all I've used too--got them at Autozone...

I wont use Autolite #1110 ones again,I had one break apart while driving--engine pounded like it spun a bearing for about 3 miles,before I got mad and floored it,and it evidently broke up into chunks and went out the exhaust..probably beat up the piston crown and head good...might have just been a fluke,but one guy with diesel experience told me "mixing" various brands of glow plugs might cause one to get more voltage than the rest,and overheat one,and cause it to burn up..I only had that one Autolite in the engine..

I've had a noisy tappet on that side of the engine after a cold start for several minutes ever since that happened--might have bent a push rod some?...it quiets down and goes away once its up to operating temparature..

I have heard Champion glow plugs are crap too,never tried them myself...most places here only sell AC or Autolites...only beef I have with the 60G's is the ones I used got VERY rusted in just a few years,and the terminals rotted off them,the hex was so whittled down I had to use a 5/16" six point socket hammered on them to remove them!--salt sprays right on them and they dissapear quick....I put hi temp grease over the new ones to hopefully prevent that from happening again...
