and out through the front of fan case.
7 Slide spacer off motor shaft.
8 Remove the 4 nuts, bolts and washers holding motor to pedestal.
9 The motor can now be removed using suitable lifting equipment, taking
care not to damage sealing washer placed between motor endplate and
fan casing.
10 Place the new motor on support pedestal and locate rubber sealing washer
between fan case and motor.
11 Position motor on pedestal and secure loosely by replacing the 4 nuts, bolts
and washers.
12 Locate motor key into keyway on motor shaft.
13 Push motor shaft spacer onto motor shaft.
14 Align keyway of impeller hub onto key and slide impeller onto motor shaft.
15 Replace hub retaining washer and shakeproof washer. Apply thread lock
to motor end shaft bolt and replace bolt, ensuring impellor is pushed back
onto spacer.
16 Apply thread locks to grub screws holding hub and tighten into place.
17 Locate impeller, according to the dimension taken during removal, by moving
motor along pedestal, ensuring motor remains square to fan case.
18 If the measurement was taken from impeller back plate to fan case, adjust
to suit and tighten motor fixing fasteners through pedestal and motor feet.
Replace inlet eye, using a bead of sealant between the plate and fan case

20 If a measurement was not taken, then replace inlet eye, using a bead of
sealant between the plate and fan case and replace outer circle of bolts.
Adjust impeller so that there is approximately 2 mm clearance between inlet
eye and front of impeller and tighten motor fixing fasteners through pedestal
and motor feet. For ignition minimising fans the minimum clearance must
be
>
1% of the relevant contact diameter.
21 Rotate impeller by hand, adjusting where necessary, to ensure that impeller
runs freely.
