Re drive couplings and shaft.
Problem is an inherent design problem with the shaft. It is not perfectly aligned which causes problems.
Niagra air parts has developed a new fix for the problem and are working on the STC as we speak. Saw the new design last thursday.
They also have new oil coolers at 50% of the price of new ones which makes overhauls less attractive.
They also have a new lightweight replacement starter for the 360s which will cut 18 lbs off and improve reliability. The bendix spring on the old starter couplers gave lots of problems.
Fyi
