I use white Lithium Grease in a Prosistel PST-61 and pack the gear box.
It's a low RPM, high pressure grease and I believe the factory has
changed from the gear lube they were using to it. It also makes far less
of a mess when you work on the rotator. BR2 is also a good grease for
this use, but really messy and is kinda expensive the last I heard.
