I'm not sure if the hub is an RP04 style or RP03 style. Yes, the accessories say big pack. Given that there is also a tool for looking at 5-ish platter packs, RP04 and later (with the smaller tool used for RM03 packs) is plausible.
I remember seeing one of these in use, for inspection not cleaning. The only pack I ever saw cleaned in the field was an 1311 pack that had been splashed by leaking hydraulic fluid from the head actuator. Cleaned off fine with isopropyl alcohol. paul > On May 10, 2019, at 12:31 PM, Brian Roth via cctalk <cctalk@classiccmp.org> > wrote: > > I could not find it in my DEC maintenance aids handbook. > I would agree that it is definitely for multi platter drives. > On Friday, May 10, 2019, 12:23:23 PM EDT, Guy Sotomayor Jr via cctalk > <cctalk@classiccmp.org> wrote: > > From looking at the accessories and the spindle, I believe that this is for > examining multi-platter packs such has those for RP03/4 and RP06 and the > like.
