Steel Soldiers now has a few new forums, read more about it at: New Munitions Forums!
There’s something like 12-13 oz of gear oil in the front ones. I doubt “dry out” is a factor unless there is another problem with a seal or excessive heat from bad bearings.
I’m certain you are aware of the two settings on the 3 way light switch “panel dim” and “panel bright”.
Light comes from the edges of the gauge. I did not see backlit numbers in person. I believe this appearance may be just the camera's view of things. Admittedly, I did have them on the brightest setting.
Yep, I have mine on Panel Bright with the rheostat turned all the way up, still very dim like it's backlit with a candle. Not a big deal, but it's good to know they should be brighter. I'll take apart the panel one day... maybe the bulbs are darkened over on the inside, or something is dirty.
Bad rheostat?
Entirely possible. I never investigated because I didn't previously realize they were supposed to be brighter.
You could try some Deoxit on the rheostat to see if it helps. I learned about this stuff in the Auxiliary Equipment section for use on the reconnection switches on a genset. It is widely regarded in the electrical community and is used extensively on old amplifiers, etc to revive these type of switches. It is available online or often in stock at your local guitar store (Guitar Center stocks it here).
No charge. No worries : )
You are awesome man, thank you so very much!
What exactly are you looking for?
Can you elaborate? I thought that a major point of the FMTV program was to use as many commercial off the shelf components as possible. To me these seem like the easiest military trucks to fix WITHOUT a military support system, unless I'm missing something.
Tis way am interpreting it too.... but it is still doable. Plan your trips with strategic stops at places found thru is bulletin board to stop at and go thru the items specified by TM when you hit X # of hours or miles. Also smaller independent Big Rig repair shops would be a good place too. Some things you won't need a shop etc. Just planned full day or couple days stay to run thru the TM checks before moving on to next destination. Many wise long rangers do this in other rigs too be it a Unimog or a Isuzu.
I must not understand your question. IR thermometer measures temperature so I'm looking for heat build up. It's easier to reach potential hot spots under the truck with a laser-pointed IR gun than by hand.
