Groda posted:Do US trailers not usually have their own brakes? hahahaha let me introduce you to the land of the free to make terrible decisions. Many low end or light duty trailers will have no brakes, even some larger trailers. Once you get into the larger trailers for hauling vehicles and equipment brakes are more common. I've owned up to a 5000lb rated trailer and it had no brakes.

Groda posted:Do US trailers not usually have their own brakes? It is not required for any trailer under 3500lb and it's rarely found on that specific class of trailer. Most every trailer with brakes have a break away system like you have mentioned. Whether it was maintained and works is another story.

cursedshitbox posted:X-posting from my thread cause it easily belongs here. Sorry you’re having to deal with this… but I have questions: What’s DPF? What does it mean to run it at 150% load? What’s a regen? Same but stationary regen? How do they differ? What’s an oil galley plug on a turbos chra? If the guy left it out, how did you have one to put in? A truck like that has no way to measure oil pressure? Seriously? How is the dipstick worthless? I can’t imagine a more simple technology than “put stick into liquid, pull it out, and check for a mark” so I’m curious to how they hosed it up In your pics of the turbo compressor and turbine, are there any faults that can be seen? I’m not sure what to look for? I’m sure you’re super busy, so only give me answers when you have time… or let someone else answer to help me understand. Good luck!

Groda posted:US trailers: Trailer hitch on a ball mount (usually), with chains to keep the trailer attached to the vehicle if the hitch pops off. Most smaller trailers (under like 2000lbs loaded) in the US don't have trailer brakes. Bigger ones may not have working brakes... The tether to lock brakes is great, unless it's corroded, the battery is dead, etc. If you have your safety chains adjusted correctly, they work fine and don't do anything crazy. I had the coupler fail on an excavator trailer once and since my chains were adjusted correctly I was able to pull safely over to the side of the road with it. much better outcome than an excavator careening into someone's house with locked brakes.

namlosh posted:Sorry you’re having to deal with this… but I have questions: 1. Diesel particulate filter. It's a ceramic substrate similar to that of your typical automotive catalyst that is extremely effective at capturing small diesel particulates. It accumulates and needs to be burnt off occasionally. If it can't be burnt off the DPF is removed and sent in to be burned at high enough temperatures to remove the ash. 2. DPF soot accumulation. 0-100% is allowable. 101-200% is overloaded. 200%+ the truck shuts down. 3. See part of answer 1. The system fires the left bank injectors on the exhaust stroke to raise exhaust gas temperatures. This fuel runs through the turbocharger turbine and into the exhaust system helping burn off the accumulated soot. 4. The part highlighted in whatever color is the CHRA. Center Housing Rotating Assembly. It's the bearing/oil/coolant chunk of the turbocharger. The boxes in white are the oil supply and the oil galley plug. When one isn't used the other is plugged. It backed out but didn't fall off the engine. See the second image.   5. Aboslutely! It just returns a boolean. Think of it like an idiot light but with some software logic. Like so.  (oil volume is calculated, not measured. probably on the rate of change of oil temp vs coolant) 6. The dipstick threads into the engine between the block and flywheel. It's a 4 ish foot long tube that inserts next to the rear main. It's hard to get a reading because of such. 7. The compressor/turbine are visibly off center and there is metal scraping damage visible against the respective housings. Also the turbine/compressor should have a millimeter maybe two of space between the wheels and the housing, not 10mm+ Humbug Scoolbus posted:Diesel Owner is a very odd language.

I had the coupler fail on a fairly heavy (definitely not that heavy) trailer once too. The car was completely controllable. I felt the trailer doing something strange, slowed down while my brain figured out what had happened, and then drove slowly to the next side street where I could safely park. It was much safer than having the trailer panic stop in the middle of the road.

Groda posted:Do US trailers not usually have their own brakes? That's absolutely not standard in Europe. I've never dealt with a trailer with brakes* since those are only required on trailers from 750kg and up and they also require a special license to operate. Incidentally the most common trailer type is a light trailer that you can tow with a regular license rated for 750kg and obviously no brakes, or a safety line. *technically false but we're literally talking "helped load one during a few summer jobs as a lawnmower" and honestly I wouldn't have even known if it wasn't for the obvious handbrake that wasn't used or the safety chain that mostly wasn't used e: Oh yeah it's 825kg or something in actuality, but it's a moot point since trailers are typically rated 750kg since the overall combination can't go over 3500kg in capacity which rules out many cars and you'd need the extra trailer license.

Groda posted:I can't see why the US version wouldn't just leave you with an uncontrollable car because of the swinging trailer (if the safety chains are under tension) or an uncontrollable car because the trailer's rammed up against the back of your vehicle (if the safety chains are under "compression"). In the EU version, you at least separate the dangerous part of the system from the passengers. Yes if you have an unbraked trailer and slow down quickly it's going to rear-end your tow vehicle. Better that than hitting something else that's not yours. quote:It doesn't seem like keeping the trailer from separating should be its own goal -- either way you've got a bunch of unexpected objects standing still in the middle of traffic, in the end. https://abc11.com/fayetteville-crash-trailer-bus-fatal/12196407/ https://www.jacksonville.com/story/news/crime/2011/04/17/law-disorder-sod-trailer-gets-loose-kills-pedestrian/15907002007/ Unexpected objects standing still are a lot better than unexpected objects flying uncontrolled in to oncoming traffic or pedestrian areas. It's better for everyone else to have the entire assembly crash as one than to save your vehicle while your trailer goes flying off to wherever.

That deep, knowing chuckling you hear is from the GM production engineer that decided they’d make LT1 Caprice radiators with plastic end tanks bonded to aluminum tubes and fins. Oh ya, and it used a fully-pressurized cooling system, including the puke tank. Lotta people learn that one the unpleasant way. And the water pump weep hole is strategically located to drain directly into the optical distributor when the water pump seal begins to leak. It’s like BMW designed the Gen II SBC cooling system.

GM's been using that kind of cooling system since before the LT1 Caprice. And they're still using it, AFAIK, except now with further things that can break - my Saturns had coolant level sensors in the surge tank. Dexshit gums they up and they eventually think you're always low on coolant, the fix is replacing that %#$@! tank. The small turbo motors (the 1.4 in the Cruze and Sonic for sure, possibly Malibu as well?) use a plastic thermostat housing / inlet with a captive thermostat.  The thermostat is held in by 2 plastic tabs that eventually snap - when it lets go, the engine stops warming up. Pull the thermostat housing, the tabs fall out and you go "huh?". This loving water outlet/distribution block always starts leaking around the same time too. Plastic. WHY DOES IT HAVE TO BE loving PLASTIC  ZZP makes an aluminum replacement for the outlet and the valve cover (also plastic). You don't dare go to the aluminum valve cover without replacing pretty much the entire PCV system though, unless you want it pissing oil from everywhere (including the turbo).

they make them plastic cause they're cheaper to build and you end up having to buy a bunch of replacements so they make even more money on a part that should just work. under capitalism nothing about this statement is a negative thing even though it's an obvious scam.

Polymer pieces are fine in principle, plastics can be incredibly durable and handle the water pressure and heat cycling just fine. I just think they use cheaper quality plastics to save pennies and build planned obsolescence into their engines

spookykid posted:One of the weirdest jobs I've ever worked was "When #2 HF radio keyed, aircraft yaws hard left" which... is loving terrifying. What was happening was someone had worked replacing wiring for the yaw trim tab, and they routed the unshielded wiring too close to the RF line for the #2 HF radio. Every time the radio would be keyed, 300w+ of RF was inducing a voltage in the trim wiring and basically going "full left yaw NOW". In the tech data there's a big warning of "HF LINES MUST KEEP A 9 INCH SEPARATION FROM ALL OTHER WIRING" but it's only stated like that in the HF radio manuals, so any other schmuck who doesn't know any better in another career field has no idea about it.

Lol, I used to work with HF systems, HF radio failures are awesome. One of my coworkers managed to create a light show by accidentally hooking up 240vac to the 28vdc power input for an HF radio. Haven't had too many other thread worthy failures but they don't fail gracefully.

Darchangel posted:The horn was sounding, and there's a at least 50% chance it's a diesel and literally needs no power to run. I'll argue most of the harness was melted together (headlights + horn is a very common thing with a burning car until the battery burns up), and any flexible sections of fuel line had long melted - which would have killed the engine. It slows down considerably before hitting the tree, also after rolling over the curb. Them things are HEAVY, and it appears to be on an incline. I'd be willing to bet the parking brake failed (from the fire) with it in neutral, but unless someone can dig up a news source or youtube video, it's just a guessing game. I've bump started cars on similar slight inclines with no problem, and they were rolling at least as fast under their own momentum. randomidiot fucked around with this message at 16:00 on Jul 24, 2023 |
