The Something Awful Forums > Discussion > Automotive Insanity > Post Pictures of Horrible lovely cell phone pic of a "simple" alignment on a 2002 Volkswagen Passat (54k miles) gone awry due to the outer tie rod becoming one with the inner tie rod thanks to corrosion:  As if it wasn't bad enough to not have any means of adjusting the front camber/caster whatsoever, trying to free the tie rod up was a delightful waste of time. There's very little room to work even with the tire off; and the only options are penetrating oil and vibrating it with an air-hammer, since the heat will not only melt the bellows boot on the rack, but also the rubber insulation that holds the threaded half of the outer tie rod into the ball socket end of the rod. Brilliant.  I honestly never thought I'd see a tie rod design that could compete with the poo poo that is the 300M/LHS/Intrepid mess, but VW/Audi managed to pull it off. loving horrible.

Dielectric posted:MINI supercharger? I keep reading about them eating all 4oz of gear oil in there, and glancing nervously at mine. I really need to pull it and drain/fill... Yep, this was on an '03 Mini Cooper S. midyear in 05 they coated the gears to help stave this off. How many miles on yours and what year? This one had obvious oil leaks, and was making horrible noises, so as long as you don't see oil leaks or hear the supercharger death rattle, you shouldn't panic. Sometimes they leak from the back, so it's hard to tell, though. I just passed 40k on my R53. I'll probably either do it, or have it done around 70k.

The leaking at the back is what I'm worried about, apparently it can suck small amounts of oil out through the seal. No noises, even with the high-tech screwdriver stethoscope. So far I've had the common stuff go out, t-stat leak and crank sensor leak. Cheap fixes but you're pretty F-ed if you let it get out of hand. Nothing picture worthy so far, gooey o-rings are boring.

H110Hawk posted:What are we looking at here? Is that powdery metallic residue what used to be whole metal guts? Severely stripped PTO/water pump driving gears. It was running for quite a while with no gear oil at all.  I recommend the shop I do above because they replace these gears on all of their rebuilds and have the best warranty I know about. I'll use 'em when I have to have mine rebuilt. Usually you have a very noticeable waterpump/supercharger rattle when it gets this bad. Here's an even better picture of what happens if you don't get the supercharger death rattle taken care of:

That's still a lot, you'd figure it'd whine really bad. I'm trying to figure out why they didn't make them helical gears.

I always thought the whine was from the rotors. Since i've been all about supercharger porn today, here's some ones that aren't hosed up:  This one's got the teflon coating on the rotors that helps it last longer, only it makes it quieter   Mmmm.

Helical gears generate axial loads that need to be controlled with more bearings, which also makes setting them up harder. They also require oil additives to reduce the wear from having the tooth faces sliding past each other.

Ok, like "ep - extreme pressure additives" in gear oils for trannies with hypoid final drive gears. Gotcha. But couldn't they make them herringbone gears? (Aside from the fact that of course they wouldn't, because that would be expensive). ------------- Being a logger must be hard http://www.liveleak.com/view?i=d7c_1314313879 One tracked vehicle rights another that's tipped over, but once its back square on its tracks the tether slips off and the previously tipped one, in neutral, goes jaunting down the slope... for hundreds of feet.

Its probably hydraulic. But that's all I know, and therefore I wonder too. My little tractor has a hydraulic drive (hydrostatic), and I've always imagined it being something like a torque converter inside, but in reality I have no idea.

Imagine a 4 pointed rotor spinning within a five pointed cavity. That's what your hydraulic pump in the transaxle looks like. Never taken apart a hydro motor, so I can't rightly say.
