I’d
say no. The is no metal in there that is going to be damaged by 350F.
350C would be another matter.

As I understand it, the
whole issue with keeping the oil temp below 210 is to keep from melting the
bearings
210 is a good limit for the side seals. If
the bearings were Babbit metal (lead/tin alloys with some copper and antimony
thrown in, invented by Isacc Babbit about 150 years ago), the melting point
would be somewhere around 550F. I have no idea what the composition of
the rotor bearings are, but I’m guessing something with much more copper
and zinc in it (akin to bronze) and the melting point would be considerably higher.
But like I said; I’m only
guessing.
