I'm trying to continue a thread that was moved to the KV and do that under a relevant subject. Jsunstar asked: "hmmm, why would a stator going smell in the oil? ive never heard of anything even remotely like that...please enlighten me...quick!" A stator breaking down would be characterized by a high resistance connection or short and that would create the very unpleasant smell of overheated or burning insulation in the stator assembly or the leads going to it. It is the smell of a radio, TV, etc., self destructing if you have ever smelled that. Not the same as the sulphur smell. The leads to the stator can be inspected by pulling the primary cover. To inspect the stator, you'll have to pull the clutch and magnet housing off. That is about 30 minutes work, requires two larger sockets (1-1/8" and 1-3/16" or 30mm), and the NUT ON THE CLUTCH IS A LEFT HAND THREAD. Jack | ||

jack, its not as much electrical smell as is rusty eggs... hmmm, any way to check stator without removing? | ||

One minor correction for a typo in Jacks post... the problem is not initially a very high resistance connection, it is a very LOW resistance connection, basically just chunk of metal across the wires. This dumps all the power of the stator through the short, and turns connection into a tiny little toaster, where the heat burns up the insulation and the oil. It really stinks. Checking the stator is easy, I have a fairly elaborate writeup in the knowledge vault. The short answer is to measure resistance between the pins on the wire coming from the stator... From memory, I am thinking it should be .6 ohms or so (6 / 10 's of an ohm). Then measure the resistance from each pin to ground, it should be infinity. Then start the bike off the battery and measure AC voltage across the pins. With the engine at around 3000 RPM, you should be seeing 50 or 60 volts ***AC*** between the pins. Make sure your meter is on AC volts, or you won't see much of anything. Full procedure (well, more elaborate then this, but less heavy then the factory procedure) is at: http://www.badweatherbikers.com/cgibin/discus/show.cgi?tpc=3842&post=247836#POST 247836 | ||

Reepicheep - Thanks for clarifying that, your words are what I was trying to say. Jsunstar - Reep is the electrical guru here, go with anything he says. :>  And if you're smelling only the rotten egg smell, it may be that all you are smelling is the normal smell of the Mobile 1 synthetic oil. You may not be having a problem with overheating in the stator. If you have any new oil, sniff those and compare the smell. I noticed when I had my primary cover off two times recently that the odor was pretty pervasive in the garage and on my hands too until I washed them well. And it seemed to be much more associated with the 75W90 than the 15W90. Jack | ||

Good point. Mobil 1 gear oil and Harley sport trans both stink just fine without baking stators. Normal synthetics and conventional engine oils don't. |
