Step 7: Removing the Old
Main Fan (continued)
Task Description
Check that the upper mounting bolts securely hold drive on the wall of the system enclosure. Remove
lower mounting bolts from the bottom of the frame.
Remove the four rubber bushings, which cover the screws that mount the fan assembly.
Loosen, but do NOT remove, four M4X8 Pozidrive front screws (which are accessible through the holes
vacated by the rubber bushings) so that the fan assembly can easily slide off. To loosen, but not remove
these front screws, turn them 12 times.
Proper tightening torque for reassembly is 3 N•m (27 lb•in).
Remove four M4X8 Pozidrive screws from bottom of the frame. The fan plate should now easily slide
down. If it does not, loosen the front screws another turn and attempt again. Continue loosening the
screws until the fan plate slides easily from the drive.
Proper tightening torque for reassembly is 3 N•m (27 lb•in).
