Gearbox Overhaul
in 912 / 914 Technical Questions
9 years ago
I wrote a month ago about the vibration coming from my 912ULS. I traded my gearbox for another one and the engine was very smooth, so I have isolated the problem to the gearbox. I sent it out and had the springs replaced, re-shimmed it, and had the front bearing replaced. I still have the vibration. yesterday I flew it, it was running fine at about 5300rpm, and the vibration just started up. i went to idle for awhile, then brought the power back up and the vibration stopped for a couple of minutes.
so I am going to change out the gear set to see if that fixes it. In the parts catalogue there is a "gear set narrow" and a "gear set wide", how do I know which one I need? My engine was built in 2012.
