They do - that's why it has two unit numbers on it.

I saw one in 1984. It was damaged beyond what appeared unreasonable
to repair at the time, but today, I'd probably give it a shot. I did
get the RK11-C and an RK05J. I haven't tried to restore the RK11-C
but I've used the RK05J with an RKV11D.

They are easier to repair than many other drives. I've found the lamp
in the positioner a common point of failure - easy to spot, too -
power up the drive and look through the door - if you don't see the
light, the lamp is probably blown. Head crashes are not uncommon, but
the heads are pretty robust. I haven't done it myself, but I've read
tales from other members about vigorous cleaning of heads after crash
events. I've also heard of blower motor insulation failures that have
been known to be somewhat catastrophic, so if you are powering up a
long-stored drive, inspect the motor and the air path. I'm sure there
are other tips in the list archives (like always mounting a scratch
monkey ;-).
