Yikes ! Run ! Some people have no issue with them if the locking surface isn't rusted/compromised.. But as "brave" as i have been over the years with the other true style of split rim as seen in my pic above, as well as split lockrings and 3-piece open-center rims, i would probably be...

I don't think I've seen a seal deal looking like that on any of the 855 cummins' I have or had :unsure: .. Now I'm curious ! .. And ,,, has anyone mentioned checking the oh-oh ring underneath the filter can bolt? I've had trouble with that little bugger on that truck and on one of my M818's

One would be really handy for filling the filter cans on these things and priming that hose to the PT pump .. A feed-thru bypass type of pump might work okay for that , if they make one with a large-enough bypass volume while deenergized .. Another one of these M809-series I got from a...

Hi Will, here's perhaps some pertinent backstory of the truck to help solve the mystery.. I was the PO of this truck and it came from a town hwy dept.. I have no idea what they did to it except I discovered an open solenoid fuel shutoff bypass knob and there was a minor chip in the fuel filter...

The interior of the little screen is the intake side , which is unusual but that's how those are.. if I understand these engines correctly, it's the injectors themselves that open to release the high pressure fuel and create return flow, not the PT pump... The PT only draws from the tank and...

question #1 = No next situation , there should be a constant trickle on the return line while engine is running.. There will be no trickle when engine is off , even if your test pump is making pressure on the inlet . Will Wagner is the cummins expert, and i don't have enough time to read all...

first of all, your truck should've come with split-lockring rims or the later 3-piece rims, not actual widowmakers .. When i was at FLW in the late-70's, that's what the 1960's-70's Loadstars were wearing... I don't recall ever seeing either of the 2 styles of actual widowmaker on a...

you would get away with what you are doing if you have a gooseneck trailer , but the ball height will come into play of course

i am visiting my 2 boys in VA and NC sometime in the next few weeks depending their schedules, both are about 2hrs from the show.. Neither of them would be interested in going although the youngest is still active army nearing 20 years service .. Perhaps my oldest boy's (younger) half-brothers...

these pics were around 1984 when i "owned" the keys to the two M49A2C's and the four 5T T&P's during "off" weekends Was given the logbook/key to the CO's jeep here for safe keeping this particular weekend , big mistake ! .. Resulted in a weekend-long unpaid volunteer adventure of jeep...

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...
