You say "The engine ran smooth etc." And WHEN was the last time that engine RAN smooth" 2 days prior to swapping? Or, last year? You really ought to start a new thread to cover this issue. It might be helpful to some of us if you will provide the engine model number and type number you find stamped or listed on a decal ON THE ENGINE. And you need to give the numbers for both engines and tell us which one you took out and which one is the replacement. What about the fuel hoses you are using? Are they new? If the Yardman tractor had sat for a long time in an inoperable condition, the inevitable varnish that will form inside the hoses may be breaking loose and migrating into the carb.

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. Here is a link that might be useful: Prius Power Split Device.

This time last year this happenend to me, wd-40 did not work! After $300 and a lot of time on-line, I got a refund check for $215 from Ford. This is a common problem! A couple of other things to watch for is the rear wheel bearings it is also common for them to wear out, The wheel bearing are covered under 100,000 mile warranty, however, according to Ford the wheel bearing cannot be purchased alone, it comes in a hub assembly which is not covered! Tricky! They ended replacing both rear wheel bearings for the deductible of my warranty $100 vs $250 each! The other is the head. Took the car in for scheduled oil change and found the head was warped. They fixed it, the next week after finding oil under the car, they replace our engine. Good Luck!

Mark. If there is one thing that annoys me more than anything else in this trade, it's the never ending line of people who tell the customers want they want to hear whether its accurate or not. Reminds me of the service manager that told one old lady that the fog that she kept finding on the inside of her car windows was a small coolant leak and we simply had to tighten a hose clamp, instead of telling her that as the vinyl interior cures it will give off chemicals that can fog the glass and it will go away completely by the end of the summer all by itself. I think I saw that car in to get the windows cleaned every week all summer long. What the service manager did was tell her what she wanted to hear, that something got fixed. You wrote "I just fixed an intermittent electrical issue for customer that spent a small fortune with 3 different garages that failed to fix the problem. " It takes four things to be able to fix a car. The right person, the right tools, sufficient training, and a broken car. Intermittent by nature are a car that isn't broken all of the time. If it happens to not be broken at the time that any of the other three shops saw the car, then they had no chance. Now keeping in mind what I started off with, people in this trade wanting to tell the customers what they want to hear, instead of the way it really is, you can go right ahead and fault the shops as you did, and play the hero card here. The facts are the forces at work inside of this industry that you allude to are going to hurt the consumer until we all learn how to be professional. Quote" The flat economy has effectively forced many employment/income/savings/credit challenged people to become self sufficient electrical/emissions troubleshooters and/or forced them to use the services of unemployed/under-employed mechanics that work from home, or on-site" Side work is stealing, pure and simple. Someone doing side work has no insurance, which a shop has to pay in order to protect the customer as well as themselves. They don't pay taxes which short changes everyone else that does. They operate in the street, or in a garage not zoned for the business, the list goes on and on. It's the classic apples to oranges kind of a comparison. You cannot compare what happens in someones back yard to what a real shop does today. Quote "Having a little knowledge also helps prevent customers from being taken advantage of by dealerships, independents, tire/brake/inspection outfits etc" Now where does one get this knowledge? In some back alley? Here on the Internet? You can find videos of people unlocking a door on the Internet with a tennis ball that has a hole cut in it. Its fake, but people want to believe it. Your response is IMO another tennis ball trick that unfortunately I don't have all day to debunk. Plus I have the disadvantage of having to tell it like it really is, not the sugar coated version that people want to hear as you did. Yes it costs money, and sometimes you might consider it "big bucks" for something that may seem relatively easy. Did you see Jerry's response just now? Quote " and the Security fault. My truck is a basic model, manual windows and locks, no electronic security. The dealer shop was successful in getting the SES Icon off, and in applying two "silent" recalls (not happy I didn't get a notice), but the Security fault did not result in any action... I'm concerned it is a computer problem, expensive to repair. The problem may be that the Security fault isn't on all the time, so if I had a reader I could look when it is on. The reality of that paragraph is first that Jerry contradicts himself in saying that the vehicle has a Security issue, but at one point says that its a base model with no electronic security. Not blaming him of anything here, but in a way that's a classic perception, and not an uncommon description that a customer might give to a shop. The security issue is likely real, plus it's intermittent. Tell me Mark are you trained and equipped to service that system? If so what scan tool are you using? (brand and software updated to 20XX model year)?? Sadly this is going to end up rhetorical, because I have to give the answer to make my point. Real techs today, understand that the ONLY tool to service that system correctly is the GM tech II, and the shop has to have a subscription to SPS. What tool would you use if Jerry would happen to own a Ford with a similar reported problem? How about a Toyota; or a Mazda; a Honda, an Acura, a Lexus, a Nissan, an Infinity, a VW, a BMW, Mercedes, Kia, Hyundai? Or any one of the other manufacturers currently available in the US market? The reality is techs and shops need vehicle specific training, and specific O.E. tooling for each one of the manufacturers or else they are working with a handicap, and potentially will find themselves unable to actually complete a given repair without sending the car back to the dealer, or having a mobile diagnostic technician come to their shop, or in fact they could come to a shop like mine for about 90% of the most common vehicles on the road. I ask you Mark are you genuinely equipped and trained to service the security system on Jerrys Truck? Would you be for all of the other manufactures that the readers here are likely to own? By taking on that expense, uncommon in the industry, it impacts what a shop like mine has to charge for even the things that are indeed easy. You attempted to make that look as if it is dishonest with your response and I take extreme exception to that. Dealerships, by their franchise agreement, have to be equipped for, and employ techs who are capable and trained to service things like Jerry's Security system. Only shops and techs who "get it" in the aftermarket step up to the plate and make the required investment in the tools, training and equipment required to do the complete job. Customers who understand this, realize that there are many ways to undercut the real professionals, but understand doing so causes either the professionals to charge even more for what they do, or else they have to dial back the services for which they are going to be able to perform for the customers. Or worse yet, simply shut down and no-longer be a viable option for the public. Think that's an exaggeration? Look at how many dealers are being forcibly shut down. If your above average, your still not trained and equipped to fill the void caused by a dealer that closes. I can't do that simply because of the volume of work that could be displaced. (There are only so many hours in a day). Back yard Bob isn't going to do it, because he wont go to any updated schools, and he darn sure won't buy the tools. Auto repair isn't cheap, it's actually under priced for what it really takes to do it correctly, and armed with the knowledge that is based in reality, a customer has a chance to find a real shop that will repair their car. That's my goal here Mark, exactly what was yours?
