Service Bulletin 14 Tail rotor shaft fwd bearing

08-28-2016 04:41:48

My R66 has about 450 TT and the teletemp on the bearing was installed 6/2015. None of the temp marking boxes had any discolor until the last flight, the 170 deg box darkened. Has anybody done the bearing update? The Ser Bul 14 will allow 180deg, but I am concerned that 170deg is too close to max.

Hello Sir. I have a 2014 66 with 270 hours. My teletemp is hanging right around the 170 mark. During its last annual- 10 hours ago, the mechanic replaced and it was right back to 170 which I was told is normal?
