EDST777 Posted April 5, 2019 Report Share Posted April 5, 2019 Hi. On my car already 160,000 km. My question concerns replacement of pulley of the generator, somebody made such replacement? What resource of this part? Thanks. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted April 7, 2019 Report Share Posted April 7, 2019 Have not seen just the pulley for the alternator, OEM or aftermarket. 1 Quote Link to comment Share on other sites More sharing options...
EDST777 Posted April 7, 2019 Author Report Share Posted April 7, 2019 the pulley means changes only with the generator? Quote Link to comment Share on other sites More sharing options...
EDST777 Posted April 7, 2019 Author Report Share Posted April 7, 2019 I would like to know how this part is reliable and whether there are problems with pulley? Whether there is such experience!? Thanks Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted April 7, 2019 Report Share Posted April 7, 2019 Unless the belt tensioner and/or belt actually fail, there are no issues with the generator/alternator pulley to date. 1 Quote Link to comment Share on other sites More sharing options...
EDST777 Posted April 7, 2019 Author Report Share Posted April 7, 2019 thanks, what main signs of exit of tensioner of belt? I know from the forum tensioner there live about 250,000 miles? Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted April 7, 2019 Report Share Posted April 7, 2019 Ah the sweet dream of only going by mileage for parts wear For most people, the tensioner will start to become obvious on starting the engine when the weather is colder. For me, below 40F or so, when I cold-started the Edge, there would be a "flitting" sound, or a playing card in bicycle spokes sound. It still had life in it because 2 years/20,000 miles later it was the same. But the dealership never found anything wrong with it. So I had an independent mechanic inspect the belts and tensioner. The belts had microcracking in them, and of course, the tensioner was behaving. I had them replace belts and tensioner. No more sound since then. Not sure if it affected the pulleys during the process. There is no wobble that I can detect, so I am hoping not. 1 Quote Link to comment Share on other sites More sharing options...
EDST777 Posted April 7, 2019 Author Report Share Posted April 7, 2019 (edited) thanks, very useful information. I am concerned by operation of the generator under loading, it means that when I gradually connect consumers of the electric power: the oven, brushes of windshield, radio, heating of mirrors, heating of seats, I begin to feel easy vibration on steering wheel from the generator. Therefore I would like to understand normally it, or such work is connected with some reason, for example with slackening of tensioner of belt or with the increased generator belt.

WWWPerfA_ZN0W Posted April 7, 2019 Report Share Posted April 7, 2019 Could be related to the generator. Could be the engine is not handling engine load correctly. You can use Forscan to track alternator behavior, just like you do fuel trims / oxygen sensors / etc. Look to see how much voltage the generator is putting out under varying load conditions. If it dips below 13.5V while driving, and does it frequently, you definitely have a problem. This should NOT cause engine vibration. Engine vibration can be caused by increase in rpm to compensate for A/C cycling ON, however. Have you run fuel system cleaner through the engine yet? I am wondering if there is injector clogging or leaking that might be contributing to uneven engine performance, or even starting to clog the converter.

Ok, thanks, I will put tension of the generator for testing and to observe its output voltage! As for cleaning of a fuel system, I do it not often: I fill in in an empty tank of additive for cleaning of a fuel Hi- Gear Jet Plus or Techron. But I do it not regularly, once in two months on 78 liters of gasoline. Did you mean it when you spoke about cleaning start? I washed out a butterfly valve in the fall, then I found malfunction of the adjusting screw of a butterfly valve, about it I did a subject at this forum, I stuck together this adjusting screw, it functions still, I do not think that it influences this process though I would be glad will be convinced of it once again. I would be glad to make comparison of the Forscan parameters of my butterfly valve and other not damaged. It is possible? To be sure that the restored butterfly valve works correctly. I did not perform other cleaning works. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted April 8, 2019 Report Share Posted April 8, 2019 ok, so no need to run fuel injection system cleaning, since you do it regularly. yes, the throttle body could be an issue. You can track it to see how it is responding through the ETC and APP PIDs and graph them. You can also remove the TPS from the throttle body and inspect it for wear/carbon tracking. 1 Quote Link to comment Share on other sites More sharing options...
