While I don't know the MR-2 specifically, I've seen several Nakamichi
machines where the pinchroller arm bearing lubrication dries out and
turns to a putty that looks like contact cement! When this happens, the
rubber pinch roller never really comes in contact with the capstan, and
it is just the take up drive that is speeding the tape along. You have
to be very careful to clean out the old lubricant, especially since some
of the arms may have tape guides on them and will affect the tape path
alignment. Again, this may or may not apply to the MR-2.
