Are the heads and flying head the same as the IBM 1311? In college, we had one of those
that developed an actuator leak. The field service tech fixed all that, then simply
cleaned the hydraulic oil off the heads and pack using kimwipes and isopropyl alcohol.
The result was that things worked fine afterwards. Obviously the clearances involved were
high enough that you could get away with that.

Their experience might give some hints about the amount of trouble to be faced when
getting the stuff working...
I supported RP02/3 and RP11 where I was working in 1980.
They were a pain in the butt to keep going then, I don't think 35 more years have
made
them any more reliable.
My desk was 3 feet from the backs of the RPs. At least the RP03 didn't have a
mechanical
latch that the RP02 had that set every time the heads moved (click, click, click click
click click click)
The good news is the head technology is pretty primitive, they fly fairly high (compared
to 3330) so there
is a chance that the mech and pack can be inspected and cleaned so that it doesn't
crash the second you try
to load the heads. It is roughly equivalent to RK05 tech in the DEC world.
