I should've posted a picture of the swash plate as well, it would've made things clearer. It's a pretty inefficient design for a brand new car but I dunno. It's the first one I've managed to take apart myself (rather than having one already taken to bits to look at) because the others I've seen all had specialised nuts/bolts holding them together. This one was just an 8mm socket on a rattlegun.

Just one of those things you take for granted. My mind is blown. FWIW Chrysler's compressor was a two-cylinder piston-driven unit for many years, Eaton made a similar piston-driven unit in the 70s. Never cracked the standard GM unit, still a mystery there...just swapped it out when necessary 'cause they're common as dirt.

How about an almost failure? Spent the past week getting my 1975 RD250 running and moving again under its own power. The other night was a long, long night of getting a new tube in the rear tire and getting everything on the rear end end put back together, which of course involved quite a few beers. Today I finally got the front brakes bled (spent two days trying with a mityvac, did it the old fashioned way in under an hour today, gently caress mityvac) and hopped on to go for a ride. On my way to get more air in the tires, it wobbled a bit. Got more air, rode a bit, still loving wobbling. Got pissed, came home, checked both tires, wiggled a bunch of poo poo, then got angry and just sat down and stared at it. Which is when I noticed I forgot to put the axle nut back on. Whoops.

Its only got 2 or 3 wheelnuts fitted per wheel, so are you sure they havent already done that and those wheels are just not as good as the ones that came with it? Or maybe they just ran out of time before torching it

Just one of those things you take for granted. My mind is blown. They're not all like that. There are lots of different designs but what they all share in common is that they're basically just air pumps. Something like the classical York-style compressor, common to many domestic vehicles for decades, is basically a little two-cylinder engine. It's got a cute little crankcase and everything.

Here's a shot of our tire from the chumpcar race a few weeks ago. Either picked up something in the hot pits or on the track because it was at pressure when we were staging. Made it <10 laps before he came in because the rear end felt a little funny.

Yeah the only hard-and-fast rule with compressors is that they're going to be a positive-displacement pump, wouldn't do to spin up to 10k rpm for a centrifugal or the like.

Or maybe they just ran out of time before torching it Possibly yeah. The best part was they took the driveline and engine but for some reason unbolted the rear half of the turbo and left it and the downpipe in the cabin. So they have a wrx engine and gearbox with half a turbo. edit: ^^^^^^jesus Christ what the gently caress? Slavvy fucked around with this message at 22:17 on Nov 6, 2013 |

Savington posted:I'm not really sure where you go from there, other than to just replace the part that injector is stuck into. The cylinder head? I don't see why they don't just crank it over and see if compression will pop it out. It seems like by doing that they just risk loving injector seat on the head or the head casting itself.

Unless it's direct injection, it's probably fitted to the inlet manifold.

It's probably direct injection, so it's a question of pulling the engine or not.

InitialDave posted:Unless it's direct injection, it's probably fitted to the inlet manifold. I don't think so chief, it's a diesel. It'll have a huge amount of carbon that has turned to cement between the injector and the injector hole. Happens when the injector starts hopping up and down and letting small amounts of combustion gas bypass the seat. What they should really do is try twisting the injector while pulling upward. At this point they should just remove the head, it's a lost cause.

Oooh I bet a good ultrasonic cleaning of the head would get it out.

If you remove the head, surely you can 'just' use a hydraulic press to push it out. Failing that, just drill the injector out.

The only time this doesn't work is when they're located in a pit in the cam cover and you can't grip them with anything.

This was yesterdays effort. Thats a 40x40x3 RHS. Well. Was. Now its cheese.  Problem was, it was dead centre in this door, and when it snapped the door skewed on the hinge and jammed. And there were two fire trucks behind it. On a total fire ban day.  Cant weld bracing to it because you cant weld cheese. So we cludged it  A fix worthy of the rust belt!

It really threw me when I first saw that because I expect diagrams of things to look like the actual thing. Turns out abs diagrams look nothing like an actual unit; they always have the solenoids individually spaced out in pairs or whatever.

They actually are in pairs - generally vertically. That one's 4x3 solenoids, so it is 4 wheel ABS instead of the 3 wheel (both rear wheels on one hydro circuit) I am used to, and it has 3 rows, which means it probably supports ETC. Each vertical triplet is a set of solenoids for one wheel circuit - one for sustain pressure, one for release pressure, and one for the ETC to supply pressure without operator brake pedal input.

Around here it's less of a drought thing and more of a "the air quality around here is starting to kill people and we haven't seen the mountains in years" thing. The whole area has no burn days when there isn't enough breeze to push all the smoke and crap out of the valley, or when there is a fire somewhere else and all the smoke or the smog from the Bay Area gets pushed over the hill and just sits here for weeks. EDIT TO ADD: The burn ban covers farms/orchards burning trash (or anything), any fireplace/woodstove where you can see smoke coming out of the chimney unless it's below a certain temperature and you have a permit from the county saying that the fire is the ONLY way to heat your home, most camping areas have a camp stove only rule as well.

Lamest loving summer ever was the year before last when our state had a crazy drought, we couldnt make a fire on a canoe trip on a bare sand bar surrounded by a flowing river. And not cause we were pussies either, god drat DNR was flying over us all night long looking for fires.
