Carefully lift the Console/Mast Assembly. Disconnect the RPM Data
Cable (B) and Power Inlet Cable (C). Set the Console/Mast Assembly
safely aside for reassembly.
NOTICE:
Do not let the cables fall down inside the frame. This step
may require two people.

Observe the cable routing to the RPM Sensor (A). Tie the piece of
string to the end of the RPM Data Cable (B) at the top opening in the
frame.

Carefully open the cable clip (D) that secures the RPM Data Cable (B)
and Power Inlet cable (C) on the frame upright (E), and release the RPM
Data Cable.

Using a #0 Phillips screwdriver, remove the screws (A1) that attach
the RPM Sensor (A) to the Fan shaft (F). Carefully remove the old RPM
Sensor assembly and pull the cable (B) so that the string extends through
the frame upright.

Installation is the reverse procedure. Tie the string to the cable end
(B) on the replacement RPM Sensor (A). Carefully pull the cable up
through the frame upright. To keep the RPM Data Cable clear of the Fan,
carefully secure RPM Data Cable in the cable clip (D) with the Power Inlet
cable (C) on the frame upright.
NOTICE:
Do not crimp any cables. Make sure the RPM Sensor is
oriented correctly on the Fan Spindle. Be sure the routing
for the cables is correct to prevent interference from
moving parts.
Note:
Before fully attaching the Fan Cage, verify that the RPM
Sensor (A) and Speed Sensor Magnets (G) on the Fan
Assembly do not touch.
