If it didn't leave black marks after you drove it back and forth a ways, then you are good to go.. It apparently released the tension on its own .. Sometimes they do, sometimes they don't. When they don't, you can try shutting the truck off, drain the air, leave the drain open, start the truck...

how exactly was it backed off? .. Rolling it down the ramps backwards in neutral (or a fwd gear) will bind it up if the air is up When anyone is in a situation where they must freewheel an aired-up M39-series or M809-series backwards , the cheat is to put the tranny in reverse and put the...

The field-expedient way to test those switches is to have a known good one on hand.. Plug in the good one and see what changes ;)

1: Yeah, those black marks are telling the world your sprag isn't shifting between fwd and reverse position as it should and the transfer case is getting bound up 2: Another situation is this: Did the truck get rolled forward while in reverse, or likewise got rolled backwards...

other than the items already mentioned, i have occasionally run into parasitic drain caused by the alternator

they are directional in the sense that the so-called "bulge/divot" is always at the right half of these lenses regardless whether it's a front or rear lamp .. It really isn't a bulge or divot, the outer face is smooth.. What we see is a set of concentric glass rings cast upon the inside surface...

here's the old-style housing with supercede amber glass

They sure did !! It's my belief they started out with the clear/clear in the 1950's and a number of them changed to amber bulbs at a later date of course, but it wasn't a uniform thing in any of the units I was in or around.. By the mid-late 1980's all of the metal lamps that had still...

What I saw in the 70's-early-80's military as well as on my own oldest M-series trucks, the front lens choices seen were clear glass w/clear bulb, and clear glass w/yellow bulb, and amber glass w/clear bulb .. All three variations of the metal lights were used .. (aside of the normal...

If you mean metallic conduit, you are correct .. Here in the rural/ agricultural areas of Northeast US, Non-metallic conduit is found on services to about 50% of homes and a higher percentage at barns, garages, and small businesses. Metallic conduit is primarily found on most services to...

Were you able to buy the fuel-rated hose per the foot? About 6yrs ago when i replaced the one in the M49A2C i called around and only one place had the hose on hand.. It only came as a 10ft coil . I feel severe residual monetary pain now that i mentioned it . IIRC it was around $100. o_O I...

absolutely correct on all counts ! .. If a system isn't 100% tight, the in-tank pump helps the multispew crank a shorter amount of time after it has sat more than a few months, or a month, or a week or a day.. Depends on the degree of un-tight :D

Just a note of detail , the "F12" Bonding Bushing (aka "grounding bushing") is only required on concentric/eccentric knockouts when using metallic raceways, ie; steel or aluminum conduit During my years as a contractor occasionally tasked by mills to troubleshoot/repair, I had seen a few...

1; in active army and then VtNG 1970's into the 90's i did not see a plastic battery box until 2009 on one of a pair of M818's i hauled out of FIG Pa .. It's warped just enough to give a little bit of clearance trouble when replacing batteries if i don't slide out the box . (regular diesel...

i will try to reach the estate of a collector i mentioned .. i had his son's email here somewhere , it's been a few years.. Maybe by now he has an idea what's there for parts etc
