I HAVE A 2007 TOYOTA CAMRY WITH 20000 MILES ON IT. I GOT INTO AN ACCIDENT A FEW MONTHS AGO. I CRASHED INTO A CURB WITH MY RIGHT PASSENGER SIDE RIM. BECAUSE OF THIS MY RIGHT FRONT BALL JOINT AND LOWER CONTROL ARM WERE BENT. THE RIM SUFFERED COSMETIC DAMAGE BUT I ORDERED A NEW ONE. I REPLACED THE PARTS AND GOT A WHEEL ALLIGMENT AND BALANCE. ONCE I GOT ON THE HIGHWAY I NOTICED THAT MY VEHICLE WOULD SWERVE TO THE LEFT. I LET THE STEERING WHEEL GO AND NOTICED THAT IT SLIGHTLY TURNED TO THE LEFT. I ALSO EXPERIENCED A VIBRATION ON THE STEERING WHEEL AND REST OF THE CAR AS I BRAKED AT SPEED OF 60- 65 MPH. I ALSO NOTICED THAT AT HIGH TRAFFIC TIMES IN STOP AND GO SITUATIONS MY VEHICLE WOULD TURN COMPLETELY TO THE LEFT AS I WOULD LET THE STEERING WHEEL GO. I TOOK THE VEHICLE TO THE DEALER AND THEY RECOMMENDED ANOTHER ALLIGNMENT, BALANCE AND ROTOR REPLACEMENT. I ALLIGNED THE VEHICLE AND BALANCE THE TIRES, I DID NOT REPLACE THE ROTORS. NOTHING CHANGED. THE PROBLEM IS STILL THERE. I AM THINKING OF REPLACING THE ROTORS SOON TO SEE IF IT CORRECTS THE VIBRATION. I AM WONDERING IF THERE IS ANOTHER PART IN THE FRONT END THAT MIGHT OF GOTTEN DAMAGED THAT COULD CAUSE THE VEHICLE TO TURN LEFT. I NEED HELP. WHAT DO YOU THINK I SHOULD DO. I

Every electrical motor has a maximum rpm that it can turn without sustaining damage. Once that speed is exceeded, centrifugal force will pull the windings from the armature and they will bind into the stator. In the case of the Prius transaxle we are actually talking about a rotor assembly that has permanent magnets attached to it. Exceed the rated speed of that rotor and it will grenade. The engineers are correct. http://eahart.com/prius/psd/ In order for the gas engine to propel the car, MG1 actually has to be a generator and provide resistance for the engine to push against, as well as MG2 being a motor that helps the gas engine push the car. Using the java applets on the site I provided you get to see the normal operation of the motors in the transaxle, and how they work together. Take note there are times that MG1 actually is forced to spin backwards. The Prius has a maximum vehicle speed of 94mph, with the primary reason being risking over-revving the electric motors and causing a catastrophic failure of the transaxle.

I don't know anything about the seal problems, but a Toyota with only 76K miles could have a lot of life left. As for $3K, I again say look at the "book value" to see what it should sell for and look at the private sale value, that should be less than what you'd have to pay at a dealer. Again, I'd look at the book on Chevy and Ford (S10 and Ranger to be in the same size range as the Toyota) and see if it is possible to get one a couple of years newer and a few miles less used for the same money. I was talking to a fisherman I "bumped" into a couple of days back. He had noted my Chevy Colorado and asked how I like it. He had a Chevy S10 of some years, don't remember, but I do remember he said he had about 300,000 on it. Yes he had replace a number of things, but he engine/transmission/drive-train was original equipment. My 1988 Dodge Ram 50, similar size, had about 100,000 on it when I traded it in (gave away) on the Chevy and the only problems I had were: Head Gasket and Carb. It was a 4WD and the drive train/clutch seemed to be in "perfect" shape. A mechanic at the dealer bought the truck, and I see it from time to time, he's still driving it to work. He said he replaced the carb, I don't know if anything else has gone. Point? 76K miles isn't a lot of miles on a vehicle if it has been maintained (mostly just oil change/filter change).

Hi Chisue, Glad you found the info useful. The $US 10,000 bid las time round I think puts you into the class two gen set area. These are good systems and popular where I live. Auto start and essentially auto everything. Good in that when the power goes out you do nothing and everything comes back on line in about 20 seconds. These units are lawn mower engine based. Typically air cooled and have two cylinders. They run fast at 3,600 rpm and are noisy. But this is not that big a deal in that this is for only a few days of running untill the power comes back on. The amount of power they can handle is about 10-12kw range. Some companies rate them higher like 15 kw, but I would say this is pushing it. Another something worth remembering is starting current. The other poster was correct in that the calculation is amount of power + some buffer. The some buffer is important. The reason why is that at start up, electric motors draw a lot more current. Can be up to 8 times as much. So to handle this surge you need a big generator head, more copper, and a heavier momentum in the engine. You can begin to see why heavier is better in generators. You have two sumps, I do not know how big these are, also the fridge. Immediately upon power restart this is when the power requirement is the largest. All your motors will be trying to start at the same time. You need to ensure that you have sufficient power to start these motors. At a guess, I think 10kw should be sufficient quite comfortably. A portable 6kw gen set may require some messing about with breakers. IE. you only start one motor at a time. Hence the power surge demand is spread out over time. The other useful thing to remember, or your electrician should know is that your generator set actually generates power as two phases. Huh? What is a phase? Imagine a smooth wave like line, in math it is a sine wave. Now imagine two of them. Just like waves on the ocean sometimes one wave is at a peak, and another wave is at a low point. Your generator will produce these two waves, two phases, and they will be perfectly out of phase with each other. One will be at the peak, while the other will be at the low point. OK now you are confused :) OK the simple thing to remember is that most things you want to power up will be a 120v one phase item. You need to try and evenly divide these items on each of the phases. Sometimes one thing is a power hungry one. This will use up a lot of power on one phase. You cannot borrow power from the other phase. Because you cannot borrow power, you have to size your generator accordingly. For example, a 12 kw generator can be thought of as two 6kw generators (one for each phase). Make sue that if you have a big power item, e.g. your cook top, that you have sufficient to power that one one of the phases. This phase thing can be confusing, and there are some items which actually do use both phases, hence what I have just said in the paragraph above may not be applicable. e.g. Some well pumps are two phased powered. Hence in general it is a good idea to have spare capacity in your generator set. This is expensive. How much spare capacity is difficult to guesstimate. My recommendation is to go for the more expensive class two gensets and stick with that. The reason why is that once you jump to class three the cost tends to almost double because of the genset weight on installation, and the genset cost itself. If you have some key big power items, e.g. you cook top that you must have running, then maybe consider a class three genset setup. From can see from your post, I do not see any big items that would reuire a class three. If you have central A/C and want to run that, then I would recommend a class three genset. May people go for a class two set up, and buy a window air conditioner which they can install and run for a few days while their central A/C is out. You also asked in your post how log you can run a genset for. Well so long as you top up the oil etc. at a shot you can run continuously untill your fuel runs out. Fuel is usually the limitation. If you are on mains gas, then almost indefinately. My genset burns at max rate such that a 500 gallon propane tank will be depleted in 5 days. Note propane tanks can only be filled to 80% capacity, so a 500 gallon tank by volume, but only 400 gallons actual LPG propane. Then your tank may not be full, say half full. So right now I have a two day burn reserve. The flip side is you do not have to run your genset 24 hours. In power outages, I only run for say a few hours for showers, heating no burst pipes etc. The rest of the time if I am out keep it shut off if I am out etc. You may want to run 24/7 however due to your sump pump and basement flooding risk. Hope this is useful, and you are not falling asleep .... All the best, Mike.
