The procedure doesn't mention it just says remove the the front pedestal cover, switch off the Blower, wait 2 mins for fans to stop spinning, and remove it. Been a while since I worked on an 81 but seem to remember removing the system monitor just in case when I did anything on power and pedestals.
i did change the bearings in mine. but the electronics were bad. the fans would spin up when powered on, then would stop. this would turn the red light for the column on. my fans are DC fans by the way.
