High pitched whine
Hello

I have just replaced my OS105 engine bearings and realigned the clutch assembly only to find The helicopter still has the high pitched whine from beforehand.

Is it possible that it comes from the small clutch bell bearing as it is now happening at high idle.

If so would someone have the exact bearing type so that I know what to order?

When does the high pitched whine occur?Part 107.

It is audible at idle increasing to annoyingly loud in the hover.Quest NEO Caliber ZG, Zenoah G260PUH, CGY750, NHP 750, NHP 115.

When the clutch engages the bell housing the small bearings in the clutch assy are typically out of the picture. I would look at the entire bearing stack as well.Part 107.

Good point about the bell bearing. One could assume from this that it is probably the top bearing which rotates at both idle and during flight.Quest NEO Caliber ZG, Zenoah G260PUH, CGY750, NHP 750, NHP 115.
