My dad gave me a 40 year old timing light from Sears. The first time I used it it shocked the poo poo out of my hand. That was like 10 years ago. Ever since then I've been offering to let other people use it and encouraging them to check their timing.

There was a fun incident when I was doing the timing on my beetle, crouched on my toes. Something unbalanced me and I tipped forward, caught myself with one hand that I planted right on the coil in an attempt to avoid all the dangerous spinny bits. Knee hit the rear bumper and I guess electricity decided I was the fastest route to ground.. zapped the gently caress out of me. The next day I put in an order for all new ignition wiring to replace the 20+ year old cabling that probably wasn't insulating for poo poo anymore.

Maybe if we had less sprawl and better mass transit but whelp. This is the biggest problem, IMO, and also basically the same reason stricter licensing standards go nowhere. The vast majority of the country can not live a quality independent life without being able to drive. We don't even have decent mass transit in most cities so rural areas have no hope, making just tolerating the fact that we have idiots driving crapheaps the easiest option by far unfortunately.

4T65e transaxle rebuilt by a guy I know on facebook. It was fine, then there was a massive snowstorm yesterday, now it exploded! I wonder why.  (they often explode when someone gets some wheelspin going, then grabs traction, and the cross shaft and spider gears exit stage left.)

On the topic of belt tension, it doesn't help that once your OEM tensioner fails it's an utter bastard trying to find one that isn't a piece of monstrous poo poo. You have a choice to either buy the outrageously expensive factory tensioner or one of the many crappy aftermarket ones available. I replaced the tensioner on my 1ZZ-FE only to have the pulley get noisy on it so i tried just replacing the pulley. I don't know how it failed as it was an NSK bearing. I replaced it with a cheap poo poo Dayco pulley which is surprisingly quiet, smooth, and stable. kastein posted:4T65e transaxle rebuilt by a guy I know on facebook. It was fine, then there was a massive snowstorm yesterday, now it exploded! I wonder why. The old AX4S/N Taurus Transmissions do this too. Exact failure mode when the system is shock loaded in low traction conditions and a wheel grabs hard. Of course you could have a whole thread on all the things that go wrong with Taurus transmissions.

A lot of early Saturns will also do this, but that's because the roll pin holding the spider gear in shoots out and wrecks the trans and the bellhousing. Operating advice in the community is either to weld that pin in place or replace the pin with a freshie every time the trans is out.

Isn't this more about driveline inertia than power ? When a spinning wheel grabs it stops and the driveline has to stop too, dumping the whole engine, flywheel, gearbox and ring gear worth of energy into the spiders. I doubt most road car diffs can handle this given a driver stupid enough.

I doubt most road car diffs can handle this given a driver stupid enough. In general the weakest link should be the traction available at the tire, unless you're running some serious tire. I'd expect the half-shafts to be weaker than the differential as well in most cases, which is backed up by the number of IRS performance cars that basically require axle upgrades if you're running slicks with a manual transmission. Hummer H1s also have a related issue due to the inboard brakes. If the differential can't transfer enough power to break traction on the kind of poo poo tires those cars end up with I'd call it a weak piece of poo poo.

And shock loading is quite different than constant load, it's basically the equivalent of a clutch dump, but on the gears that are only really meant to see a small percentage of engine power. And with the whole driveline contributing inertia instead of just the engine. Kafouille fucked around with this message at 17:40 on Mar 16, 2017 |

My mom had a 1996 Taurus Transmission #1 - died around 100k miles I bought the car from my mom with a new transmission. Transmission #2 - died under a year, rebuilt under warranty. Transmission #3 - lasted about 35k miles, had it rebuilt Transmission #4 - dunno how long it lasted, I sold the car not long after This was before I started working on my own cars. The bills from that Taurus drove me to buy tools. It seemed like it needed brakes twice a year. And towards the end, the temperature gauge used to fluctuate up and down while driving.

And with the whole driveline contributing inertia instead of just the engine. Sorta kinda. The spider gears see full load when drag racing too, they just aren't spinning. They still have a huge amount of force applied to them, because they're what engages the side gears. Shock loading is a serious problem, but I've done poo poo like that to the differentials in my jeeps (aside from dana 35s - which suffer the same sort of failure shown here) dozens if not hundreds of times, onroad and offroad, without blowing the spiders out of any of them, even with oversize tires installed. The fact that this silly rear end 4T65e can't handle a bit of wheelspin (on an open-diff FWD car... that they presumably know is going to be driven in the snow, given that it's produced by a company based on Detroit) and then grabbing traction is not much of an endorsement for those who designed it.

Story of mine: Coming back from Lincoln NE in late August of last year hauling an alumalite gooseneck full of goats and assorted peripherals when the dash on the 08' Chevy 2500 reads "Hot transmission". Well poo poo. Pull over, it's puked a portion of the tranny fluid all down the back of the drive train, onto the trailer, just making a mess. Ended up calling the brother in law to bring a case of fluid so we could drive for 15 minutes to stop for 15 to let it cool down. It should have been about 2.5 hours to go the 150 miles home. It took about 6 hours and towards the end the truck refused to shift out of second, and didn't have reverse. This thing was cooked and you could smell it a mile away. 2k and 10 days later the local shop rebuilt the transmission and we had a conversation that basically went "well, we're not sure how you managed to get it into our shop, but she's driving fine now"

I've never done any towing myself but I've always heard that if you're doing it to any serious extent you should fit the largest transmission cooler you can onto your vehicle. My favorite autobox preventative aside from fluid changes is Lubegard http://www.lubegard.com/~/C-303/LUBEGARD+Automatic+Transmission+Fluid+Protectant Supposedly a lot of transmission shops rate this stuff highly. Once I discovered it - I put it in everything I have ever owned and I've never had it cause a problem. Always seems to make the transmission less "Lazy".

It's me, I am truly the horrible mechanical failure... My wife has had this 2000 Corolla since almost-new and it developed a misfire yesterday, I can't possibly imagine why...  As much as this picture is a story about my horrible maintenance routine on that car, it's as much a story of just how hardy these Toyotas are. Nearly 210,000klm on the motor, it gets fluid changes when I occasionally remember that cars-need-fluids, and obviously gets plugs even less frequently. As I've never touched them previously, those plugs need to be at least 6 years old. Come nuclear winter, the only things left alive will be Keith Richards, mountains of roaches and this Corolla. I'll shed a tear when it eventually dies or gets sold to a uni student.

It is likely to be a while before the final accident report is available but my money is on a counterfeit part. https://en.wikipedia.org/wiki/Unapproved_aircraft_part quote:The crash of Partnair Flight 394 in 1989 resulted from the installation of counterfeit aircraft parts.[5]

Cartoon posted:In August 1993 a group of criminals stole a cockpit computer from a Carnival Airlines aircraft at Fort Lauderdale-Hollywood International Airport. During the day the criminals contacted potential buyers at John F. Kennedy International Airport in New York City. The buyers were actually Federal Bureau of Investigation (FBI) agents of the "Operation Skycrook," which performed sting operations to thieves of commercial aircraft parts.[6] It pleases me on an aesthetic level that both of these incidents involve the Miami area.
