Time for 'nother story from the same shop as Clown-man and the diesel.
Know the difference between a fairy tale and a sea story? A fairy tale starts with "once upon a time" and a sea story starts with "so no E36 M3, there I was..."
- Chuck, Dad, and several other old Marines I have known
So, no E36 M3, there I was...
This was a heavy equipment shop tucked away well back in the corner of a USAF base somewhere here stateside, stuffed far enough away in the back that it was pretty much us back there. Due to the mission of the base there was a LOT of vehicles in the fleet, both regular ones and heavy equipment stuff. Hell, there was a tank repair shop on base, which is weird for a USAF base. Also due to the mission, we had many cranes for maintenance required on the airframes and other such.
One day a BIG damned crane came in. Gods knows how it got into the yard. Normally you'd say "well, they drove it in, didn't they?" and I assume they did, but this took some effort as the boom was stuck in the up position, thankfully the telescoping part of it worked and it was completely collapsed, just the main boom was up. Crane was big enough and center of gravity so berkeleyed up that they must have been absolutely creeping, likely had a cop escort, and some of the CE guys with them in order to lift power lines.
I liked cranes, I liked hydraulics, I (surprisingly) liked the electrical system for the hydraulic controls. I volunteered for it and was given the crane. Went out, in processed it and found some other minor problems with it but nothing that really pointed to anything that would prevent the boom from dropping. I started troubleshooting.
And I kept troubleshooting
and I kept troubleshooting.
and... I kept troubleshooting.
and.
I.
kept.
troubleshooting.
It was a beast. A week and a half or so in, I went and got my direct supervisor and asked for his help. We went over everything that I'd done, we went over a couple things that he thought of. We checked with the other guys that normally worked on this crane before I got there, checked what he suggested, got nowhere. My direct supervisor knew a friend that had retired from the USAF and went to work at a local USN base as one of their crane inspectors, nothing. He even came out on a day he had off and poked at it with us and we messed with it and got nothing. We called the manufacturer, went over our process, everything we had done, and when they got back to us with other stuff to work on we checked what they suggested with no results, they offered to send us a technician in order to help troubleshoot (at an exhorbitant rate) which we declined.
This is maybe a month and a half in. It sucked.
I'm pissing and moaning about this with my supervisor during our morning break (15 minute mandatory inside break twice a day because of the heat, entire shop went in the breakroom and hung out.) Civilian HMFIC and the MSgt in charge of the shop are listening to what we're saying and I notice them sorta giving each other the eye and sorta mumbling to each other.
After break, I head back out and they follow me with my supervisor in tow. Ask me what I've done, what I haven't done, etc etc. Supervisor and I go over it all. We covered everything, every aspect of it. They take a couple steps away, turn their backs on us and talk to each other under their breaths. Eventually they come back and tell me I've done some good work, to jump on a D7H dozer that I regularly worked on for some routine maintenance stuff and the two of them would look at some other options such as calling for the technician.
"Oh, and BTW Airman Asa, before you work on the 'dozer there's some drips down there; grab the spill kit and one of the big drip trays. I'll use that as an excuse to show Airbaby Samuels how to clean a spill outside. To be clear, I meant the real big one over there." MSgt Johns says and points at a pan that was about 8" X 48" x 36"
I give him the hairy eyeball and go and get it and the other stuff he asked for, then start doing a L.O.F. on the 'dozer. While I'm doing this I see the HMFIC and MSgt having a quiet talk with Hank the civilian with the most seniority in the shop (was happy being the shop fabricator, didn't want to run anything.) The three come to a conclusion and go about their separate ways and I get back to work. I'm nowhere near done with it when the lunch bell rings. Like break time, we all head into the breakroom and sit down for food. HMFIC and MSgt haven't joined us.
About 5 minutes before lunch break ends Hank scoots his chair in front of the door, says no one is supposed to leave till he says so, then he takes a nap in his chair.
Everyone kinda looks at each other like "what the hell?" and we sorta shrug and get back to doing nothing.
Lunch goes from 45 minutes to an hour. Hour to an hour-15, hour-30 and so on. Finally just shy of 2 hours, we get a knock on the door. Hank wakes up and opens it. HMFIC and MSgt are outside looking wiped out. We all stare and they tell us to go and get to work. I head outside with everyone else and go back to the 'dozer. I look outside and see the boom is down. I'm amazed. Straight up gobsmacked. I point it out to my supervisor and we both look at the MSgt as he trudges into his office, he looks over and says "Airman Asa, we found that leak. Please clean that up and make sure that all the fittings on that POS are tight before you send it."
Once I got it inside and apart, I found that one of the control valves was broken in such a way that when you pulled the lever it felt like it would engage to drop the boom but it was really kind of skipping? I've got pictures somewhere, but its hard to explain. We ordered a new one and got it out and working again.
I never got a straight answer from anyone, but I am 95% sure that those two magnificent bastards went out there and loosened the boom's hydraulic line in order to get it to drop. In order to do that they had to have been inside the cradle where the boom would rest once it was down, risking becoming a pancake. I can't imagine the scramble that would have been necessary in order to loosen it, then get out from under it.
