3.5.1.1 Removing the ISE Upper Bracket
This procedure assumes you have removed the ISE as described in
Section 3.4.1. Remove the ISE upper bracket as follows:
1. Place the ISE on an antistatic mat.
2. Remove the two Phillips screws at the rubber shock bushings that
secure the upper bracket to the head-disk assembly (Figure 3–7).
NOTE: RF72s and RF71s are secured to the brackets using the outer
bushing positions. RF31s are secured at the second and fourth (from
the front) bushing positions.
CAUTION: Early models of the RF-series ISEs use four screws of two
different lengths to secure the upper and lower brackets. The two longer
screws (by one-eighth of an inch) must only be used in the shock bushing
toward the back of the drive.
