Ferremit posted:Less a mechanical failure, More a Mechanics failure. Im upgrading the speakers and stereo in my mates hilux and pulled the door skins to find these... Please don't suggest that as being a Mechanic's failure. Stereo installers have no connection to mechanics. That is in the top 10 percentile of installations I have seen come from a stereo shop unfortunately. That is a different level profession, and I do not appreciate being lump summed into that mix.

You can even see where the plug weld broke free from the 3rd member. It's pretty common in bad accidents involving Explorers and other vehicles with a cast-third Ford 8.8, I've seen it a few times at the junkyard. Ford in their infinite wisdom hammered plugs into the holes instead of using the usual big loving plug weld, and having the tubes spin or pull out is common in bad accidents and on off-road vehicles. The fix is to weld the tube into the cast section before installing the axle, or at least before it spins.

Groda posted:Nothing failed here: Is that a multi-cylinder hit-and-miss diesel? I've watched it a few times, and can't be sure. Seeing these hit-and-miss engines run would be far more interesting with a load on them. Dyno runs, basically. What happens when you overload a hit-and-miss? Does it bog and stall like a conventional engine?

Yes that's a hit and miss. Diesel.. I have no idea, probably. But under load they sound like a normal engine. Think of the "miss" part as a rev limiter, they shut off cylinders to maintain speed.

I thought that was impressive. It even had the perfect cup-and-cone with central planar shear failure mechanism.

I have two failures, one dramatic and one not so dramatic. This is the passenger's side timing chain tensioner rail from my '86 Toyota 22r. These are infamous for breaking apart and getting sucked up into the oil pump pickup, causing a drop in oil pressure. The chain tensioner is hydraulic, so the loss in tension from a failed guide rail is exacerbated by this. Ugh. Thankfully I caught mine early and replaced it with an upgraded rubber coated steel rail.  This failure is slightly more dramatic. This is what happens when you run a duramax 6.5td completely out of oil. Thanks previous owners of our company van!  (Hosting mine)

I mentioned this to Seat Safety Switch when he linked it to me a while back. I don't know how the gently caress this guy is doing this. Grinders typically run clockwise. So this dude is either grinding with the close side of the wheel, where he would have had to remove the guard to do so (dumb, but not fatally stupid, and sometimes necessary) or he is holding the loving thing upside down  Either that or he's holding the handle at extension and the disk is pointing at his crotch which is even more  Despite that, spraying sparks at the tanks is silly, but it won't hurt anything except the gas lines. I mean, I still wouldn't do it, but it should be ok for a little while.

I've held the grinder upside down to get in tight spots sometimes. It sucks, but it gets the job done.

Well, sure. We probably all have briefly, but it's not the kind of thing you want to do for a long time right? it's awkward and really uncomfortable. He's been doing it long enough for someone else to not only notice, but to get out their camera and snap a picture. Either that or it was all staged, which is certainly possible.

My first question is how is he going to handle throttle inputs to two vastly different engines? Second is what the hell is the weight distribution? My guess is 30/70.

The only way this could be better is if he'd swapped the entire front end, steering rack and all in with the V8 for four wheel steering.

Godholio posted:My first question is how is he going to handle throttle inputs to two vastly different engines? I'd just run them both as cables, and perhaps put a lever on one of them so that the same amount of pedal travel gets you to 100% throttle on each engine. The wildly varying power levels shouldn't be "that" different than a car with a 30/60 rearward bias on AWD.

Why would it matter if the front engine is doing 3000RPM in third gear and the rear is doing 4000RPM in second gear, if that's what matches up to the same forward speed? It's not like he's actually hooking these things up with a transfer case.

 Harmonic Balancer chewed out the rubber bushing and then chewed into my TDIs timing belt. It made NO NOISE, until the timing belt shredded and wrapped around the crankshaft, locking the engine.  It survived this. Timing belt held. Still, scared the hell out of me, I was sure when I had it towed that was the end of my reliable little $600 Turbodiesel.

grover posted:That seems fine if the two engines/transmissions are identical, but how would you handle it if your engines were running at different rpms and different shift points? Link 'em anyhow, and shift both whenever the lesser of the two hits redline? Think of the through-the-road hybrid cars that are coming out nowadays.

Something similar almost happened to my 4cyl YJ. The harmonic balancer worked its way loose. I was driving in the south Georgia boonies, and I heard a rapid tictictictictictictictictic sound that came and went. When I got back home, I popped the hood and discovered that it was my serpentine belt being chewed to shreds, and loose ends were smacking into and wrapping themselves around the radiator hoses. I replaced that belt, and that's when I discovered it wasn't sitting right on the balancer. I must have driven 200 miles like that before getting it fixed.
