veedubfreak posted:Roadbikes are built to be -just- tough enough to not blow up constantly. They use much fewer spokes to keep weight down. A mountain bike, even a cheap one, is going to be able to put up with much more abuse than your standard road bike. Whatever the exact reason, it only happens to me on 700c road wheels. I've never bust a 26" spoke on a mtb wheel.

If everything else is equal a 26in wheel will always be stronger. A road wheel also has a narrower spacing, (130 v. 135 mm) which makes is weaker as well.

ExplodingSims posted:Do impending mechanical failures count? Ran into this poo poo constantly when I was in the business. Hello HVAC buddy. Yeah, when you run your finger across the condenser coil and it disintegrates, it ain't good. When you spray leak detector on it and it looks like one of those kid's toys that makes piles of foam, it ain't good either, and it's always "It worked fine yesterday" when "yesterday" was July 3rd. gently caress aluminum coils too, while we're at it.

Lugnut chat: A guy I work with bought new tires for his Ford Ranger at WalMart because he was in a hurry. They left a lugnut with half a stud broken off in it in the cupholder, and a note on the service sheet saying "customer must have cross-threaded it, it broke off on removal." Dude's a car guy (has a Nissan 240 project he's working on [bought the salvage-title Ranger as a DD while he puts a new engine in the 240], a '65 Mustang basket case in storage back home in SoCal, and is currently restoring a coworker's '69 Ford pickup), rotates the tires himself and starts the lugnuts by hand, it's obvious from the direction of the tear that the Walmart tech went to town with the impact and cross-threaded/twisted it off putting it on. According to a friend of his who works at WalMart, they'll pay for the third-party repair job if he complains enough. He showed it to me a couple weeks ago and I forgot about it, on Monday I'll ask if he got it fixed. I got tires at WalMart (well, Sam's Club) once -- the first set I bought for my first car ('84 Jeep SJ in '1997) -- and they didn't break any studs, but did somehow manage to give me a defective tire AND mount it backwards (was the cheapest BFG A/T with directional tread).

This is actually kind of an awesome mechanical failure. Probably been posted before, this thread's been around for ages, but it's still good. https://www.youtube.com/watch?v=kCsSVLZ6wCI

They should be checked for shrapnel damage. 50/50 chance of that being lack of oil in the tcase or a seized double cardan joint causing the driveshaft to violently rip the case in half. Melted shift fork bushings, signs of heat damage, trashed bearing surfaces, and powdered metal all over the inside of the case? No oil. Otherwise, check the driveshaft for seizure.

The failure is me...I brought my car to an indie to get some struts out (seized in with rust) that I got stuck on. This is what I get, I guess.I just got the car up on stands to take a look at it, work was about a week ago. Been driving it to and from work. Thats one strut mount hole just...bored out? Slag everywhere from I guess drilling or grinding the old bolts/sleeves out. They literally just put a crush washer on and installed the new bolt on top of the slag. I am speechless, they are local and I am going to walk over there and talk to them about it. They arent touching my car ever again, I am getting 100% of my money back and a new trailing arm, at the least. gently caress.

I've done the same thing before, but if you are careful, you can not completely monkeyfuck the holes. You just cut the bottom tabs off the shock, burn the rubber bushing away, heat up the inner sleeve, and hammer the bolt out. Jesus H Christ... I also like the Grade 3 (AKA Cheese-grade) bolt without flanged nut. Guess they were too cheap to spring for new OEM hardware.

So it is, three dashes. That also means that it's SAE, instead of metric.

some texas redneck posted:Driving on the highway in 4-HI, or lack of lubrication? It is (well, was) a NV247 so there is no 4WD high range locked - just "All Time" that uses a gerotor-based lockup in the event of rear wheel slippage. Only other choices are neutral and 4Lo. I'm thinking Kastein is right on with the driveshaft suggestion. There was a later photo posted with the back half of the thing absolutely soaked in NV247 juice. I can't think of any way the case would manage to dump all of its fluid quickly enough to cause that failure without being noticed. Edit: Kastein, is there any knowledge rattling around in your head on how much of a pain it would be to swap a JK 241 in place of a V8 WJ 247? While I hope to never need to, I've literally seen the standard 241s get given away for free locally.

A customer came in. Invoice said: FRONT BRAKE ROTORS REAR BRAKE ROTORS PA STATE SAFETY AND EMISSIONS INSPECTION COURTESY CHECK Order Notes: Customer installed own pads and now it makes grinding noise, thinks it needs rotors now. There seems to be a SLIGHT issue with the inner pad here...  That's right - the backing plate of that inner pad is against the rotor. It finally happened. I didn't think I'd ever see it - but there it is.

0toShifty posted:A customer came in. How the everliving gently caress can you have sufficient mechanical knowledge to disassemble a caliper, retract the piston, remove the old pads, reinstall the new pads, and put the whole thing back together, yet still somehow get a pad back to front. I know we all have off days, but that's a pretty obvious screw up.

All it takes is be in a rush or be way too tired to be working on something that important. My Dad (has been working on cars forever) managed to install a pad backwards in the race car last spring because it was 1am and they'd been working on poo poo since around 10am. They unloaded it from the trailer and I thought it sounded strange, did a lap around the paddock then pulled the wheel. Inner pad was backwards.

I once forgot to tighten a caliper bolt past hand tight when someone was talking to me during a brake swap. It fell out on the dirt road to the track. Was super glad I didn't make it on track that day.

I have lost brake pins from two different fleet rangers. On two seperate days. And two different trucks. Never did it again since. Now I use a 1/2 breaker bar for most bracket bolts and a long handle 3/8 for the slide bolts.

Was super glad I didn't make it on track that day. Forgot to install (or bend) a cotter pin that locks up the retaining pin for the pads. The retaining pin worked its way loose over the next 2-3 weeks and a pad popped out as I exited the interstate. My heart sank as quickly as the brake pedal, but it was probably the best possible time/place for that to happen.

That's a really good spin on it. I imagine that eventually everything that big has oopsies on site, and showing they can get decontamination done and the unit back in service that quickly is probably a good look given how much of a pain environmental regs are (or supposed to be) about spills

Actually, I thought he did a fairly good job in this. Not only did he show off how easy it was to repair the larger piece of equipment, he also got in some feel good enviromental management stuff and showed off another one of the company's products without coming across like a ~salesman~.

From a marketing perspective, the environmental protection mentioned isn't there to make greenies feel good, it's there to make board members not violate EPA rules. So it's actually much more effective than you give credit because he's speaking to the operations managers who are responsible for the mine revenue to tell them how easy it was to get back online, and also the chief internal salesmen, and to the board who don't want to get sued out their rear end for breaking environmental laws and are also decision makers who write the cheques.

If it were me, I'd have fixed the big digger and then used it to clear up its own mess. The not-paying-very-close-attention-to-the-voiceover message I took away was 'this show-prepped, brand new machine will piss itself and dump toxic waste over the ground and it takes so long to fix that we had to get another machine to clear it up before it melts the Earth's crust'
