Hey, everyone! I'm in the process of doing a full service on a machine with the 2015 800 motor. I was having some issues with oil pressure light coming on at idle after it's warmed up and also a leak near the sensor. I replaced the sensor and still had the leak. I just now discovered that it's actually leaking at the grommet where the stator wires exit the case. After doing a bunch of reading on here it seems that is a well known issue. I think I'm going to try the permatex or rtv fix first and see what it does. Unless someone recommends I don't! Now, for my actual question. During my trial and error search for this leak, I saw a set screw above the oil pressure sensor. I backed it off and cleaned up around it. Then when I put my sensor back in I realized the sensor wouldn't snug tight. So I threaded it in as far as it would go and then tightened down the set screw pretty tight and then I was able to snug up the sensor. Does anyone know what that set screw is all about? I've never seen a single person mention it in any video I watch or post I read. I just want to make sure I don't mess anything up! I really appreciate the help!
