A rubber boot holds them in, he broke something to rip the wheel out of the wheelwell, and the boot just rips and the tripod joint falls apart.

i've worked on trannies now from a couple vintage motorcycles, and i'm surprised that they don't look much different than that one here. i suppose the gears must be bigger, but you're still putting all your power through two little teeth there. or more than two if they're helical cut? anyway, 25-50hp? sure i can believe that? 250? i have a hard time understanding how that works.

Helical gears, so you have a longer gear than the width. That and good metal.

Maybe so it's either there or not? With braided/twisted cable you could snap a few strands, causing the bolt/whatever to loosen without visible outward signs? Maybe?

Cable doesn't tie up the same way, safety wire pliers woudn't effectively twist braided/stranded wire probably. The adjustments on my old Case crawler's diesel pump are cabled shut and then have lead ferrules.

It may have been the flywheel taking the torque converter with it but there were parts everywhere and the shop it was towed to said the converter caused the damage. We were lucky the car had only been running a couple minutes so the fluid wasn't up to temp. High horsepower cars still make me a bit nervous.

Scatter shields and/or bellhousing blankets are practically required when exceeding the OE RPM in large engines.

I never quite understood why this is conventional wisdom; even a perfect weld can never match the optimum alloy, processing and annealing that gives a solid piece of metal its particular combination of strength and flexibility. Plus, the process of welding weakens the surrounding metal. A good weld will be strong, yes, but not necessarily stronger than an uncut piece.

Welding filler is almost always specced to have a higher psi rating than the surrounding metal. You can always retreat metal after welding, which is what is done anyway if its that specialized. Or not welded in the first place.

A few failures out of tens (probably hundreds) of millions? You'd rather wear the transmission earlier because of an extraordinarily rare failure probably caused by abuse?

Geoj posted:

Not questioning that this caused the problem.

To me, I'd rather risk my transmission making GBS threads itself 5-10,000 miles earlier at the very end of its lifespan than run a clutch disc with springs in it. Its not like a sprung clutch disc throwing a spring and requiring a clutch replacement (or worse) on its own is something that's completely out of the question.

I'm more saying its an extemely improbable failure that you focus on as some sort of justification to run something that may not provide the cushioning factors required by the OE transmission. There is a reason that nearly every OE clutch package has them.

I have yet to see a single hub spring failure that made a clutch not work (seen pictures of a few but the springs are almost always captured on the engines as well as the sides between the riveted plates), saw one break all its hub springs and they stayed where they were captured but hey 11K RPM on a Honda OE clutch might do those things. They aren't a HIDDEN DANGER OMG, so unless you're some sort of powertrain/mechanical engineer and 70 years of clutch design on a quarter of a billion vehicles have been ticking time bombs, you're being silly.

There's far far more chance of friction material rivets failing due to abuse than just about anything else on a clutch. Then the friction material itself. Then the input shaft. Then probably the pressure plate fingers.

T&P valves are never tested by homeowners because if you don't test them regularly (like they say in the manual) then do it once, it will probably leak. FOr catastropic failure scenarious, you'd likely blow one of many other parts of a house's plumbing before a pressure vessel would. Hell, the copper flex lines connected into to the supply and house would probably go before the tank would rupture. Not to mention cheap bathroom supply valves, crappy hoses, etc.

This does not hold for very old heaters or heaters not so old but with atrocious water attributes, because those can have pinpoint failures from over pressurization and corrosion.

Wet-cell car batteries are nothing but some ABS plastic, two lead types, some plastic matting, and sulfuric acid, which none are hard to mitigate. Spill/leak/burn is just acid and maybe some sweeping to do. Now that acid can combine with plenty of other things and do some awful poo poo, hence the mixed load consideration.

It is an oversight regarding lithium-based and Nickel-based batteries, because those burning is an especially bad thing. They don't really leak.

That does not do the same thing at all. Phosphoric acid 'converts' the rust to non-reactive Ferric Phosphate. HCl just removes the rust and leaves the metal bare ready for more rust reactions.

Production drum brakes are almost always lighter than their disc counterparts. This is talking rears since only large machines use front drum brakes anymore. Drums do a terrible job at rejecting heat from the unit, and its a mostly unrecoverable problem. You can't have an emergency brake on a multi-piston caliper, so either put a second mechanically operated one(as massive waste of weight since there's not really anything short of a real race car or Veyron (stopping from top speed repeatedly) that would need more than a rear single piston sliding caliper. BMW M5s have the same simple calipers for the front and weigh a shitload, no AP or Brembo equipped. They're nice to look at and even Brembo units are lighter than some normal iron single piston units, but an aluminum Brembo with a second caliper and associated pads and knuckle tabs, etc versus just a single caliper?

Disk brakes self-clean, reject heat very well, automatically adjust, are easier to service, and safer when compromised by water. Drums have that nasty tendency to hydroplane inside when the interior is in contact with water.

I wonder if the shocks were blown on that Corolla beforehand and the lower ride height put the Silverado over the bumper in the impact.

Shocks don't set ride height, springs and suspension geometry do. Its a case of a high body on frame vehicle being higher than 90s econobox that certainly was 'not designed for that crash'. Its the equivalent of being hit by a small dumptruck from the 90s.

That's not cryptic. It's fine that you don't know what it is, but anyone who has done basic maintenance on a car made in the 80s or earlier knows exactly what this is with no further explanation needed.

There were cars post-1980s that still had distributors, though coilpack or coil-on-plug got cheap enough to use and basically became a requirement once the emissions regulations got too strict for a spinning piece of phenolic with some contacts on it.

You probably already have this, but anyway: https://docs.google.com/viewer?a=v&...cyY2Ix&hl=en_US

I could probably find a better engine than a econobox Honda unit. That and it probably wouldn't fit, since the crankcase and gearbox are a singular unit with the original. That and its pretty much a Kei car in dimensions.

I'm pretty sure you could almost park this Honda inside any 90s Civic.


edit: If anything I'd put another motorcycle engine in, definitely fuel injected and probably Honda. The G10 turbo Chevrolet Sprint motor is too heavy and hard to find, also still likely too large.

Thankfully it kind of slowly collapsed to the side so no one got hurt except his car.

Your jack looks to be made for a specific place on your car, not a random car. More "universal" jacks don't have a bump in the top with a corresponding divot on the bodyshell or chassis.

Lesson learned and thankfully no one was injured by my mistake. His car had divots in the same place as my truck, so I figured it would be fine.

You probably loaded it the wrong direction then, they are made (obviously) to not have to do any lateral load holding, and if jack where the car loads that direction, you get your type of failure.
