my two current volumes (which have greatly reduced information compared to the older versions) state the following;
max gen drive oil temp 157 C.
it also states that it is not AFM limitation.
in the electrical section it says;
higher than normal rise indicates excessive gen load or poor condition of drive.
lack of adequate cooling will generally cause the rise to decrease.
readings above 20 ARE USED BY MX IN TROUBLESHOOTING DRIVE PROBLEMS.
the only limit i see as valid is the 157 C. i understand that will cause the light to come on. then use the QRH and only then. i think it will apply to the impending break down of the lubricant close to the engine oil temp of 160-165.
i would not add the rise to the in and go for the disconnect myself.
if things are getting warm, i was told to consider turning an electric hydraulic pump off to help cool it if all else is okay. (that was an unofficial suggestion from United instructors in Denver)
