5.11 REPLACING THE MOTOR OR COOKER FAN
After carrying out the operations described in 5.1 above, to replace
the motor or fan proceed as follows
T64E T75E T97E: Remove the rear panel (fig.19 item D) by
unfastening the fixing screws.
- Disconnect the motor electrical connections.
Only on T64E disconnect the terminals of the heating elements using
a second wrench on the locknut as an anti-rotation and prevent
forcing the terminal.
NOTE: Forcing any of the heating element terminals during
connection / disconnection of electrical cables, irretrievably
jeopardizes the entire resistors!
- Remove the two braid clamping strips by unfastening the fixing
screws.
- Move the insulation and dismantle the rear cooking chamber panel
by unfastening the fixing screws.
- Take it to a worktop, straighten the plate preventing unscrewing
(on T75E 97E only) and remove the left-handed screw at the centre
of the cooking fan.
- Remove the fan with the aid of an extractor
NOTE: The left-handed screw must be turned clockwise to
unfasten it; the fan will not come out of its housing unless an
extractor is used.
- Should it be necessary to replace the fan only, perform the above
operations in reverse order to reassemble.
- To dismantle the motor, remove the four nuts on the feet of the
motor and pull it out.
- Carry out the above operations in reverse order to reassemble,
taking great care that the gasket sliding on the drive shaft is properly
reassembled and does not force the rotation of the motor. Also make
sure that the conical parts of the drive shaft and fan are perfectly
clean and smooth.
NOTE:
Before startup, check that the engine rotates freely otherwise it
could be damaged.
- Restore any damaged sections of insulation and insulate with high
temperature aluminium adhesive tape.
TT98E: Remove the back panel (fig. 38 part.
T) and inner casing (fig. 38 part.
S).

NOTE THEIR EXACT POSITION SO AS TO REPLACE
THEM CORRECTLY.
- Loosen the fastening screws on the hub (Fig.
39 item A)
- Replace the fan, taking great care to refit it in the SAME
POSITION AND DIRECTION AS ITS PREDECESSOR and
making sure that the distance between the fan hub and motor base is
the same as the one stated in Fig 39
- To replace the motor, after disassembling the fan, proceed as
follows:
- Remove the two screws fastening the motor (Fig.
39 item
B)
- Loosen the back band locking the motor (fig.39 item C).
- Replace the motor.
- Fully tighten the two fastening screws of the motor (Fig. 39 item
B) and then tighten the nuts (Fig. 39 item
G) compressing the split washers as much as possible (Fig. 39
item H) so as to avoid excessive deformation of the motor base.
- Carry out the steps in reverse order to reassemble.
NOTE: Make sure that the fan rotation direction is the same as
that on the back panel of the baking chamber (fig. 39 item D and
E).
NOTE: If replacing the motor with thermal sensor
Tab.C Item 30 - TT98E: Tab.B item 51), remember to refit and
restore the electrical connections.
