5.4 Purpose, Dismounting, and Replacement of the Air Blower
The air blower (Fig. 7) consists of an
electric motor with a scroll housing
attached. A spinner is installed on the
motor shaft. When the motor shaft is
revolving, the spinner and the scroll
generate air ow going to the combus-
tion chamber to ensure burning as well
as to blow off the combustion chamber
to cool it down and remove residual
fuel and moisture before the beginning
and the end of the burning process.
When the motor or the spinner are
faulty (the spinner hits the scroll or the
cover), locate the cause of hitting and
remove it and, if impossible, completely
replace the air blower with a new one.
To identify the fault correctly:
Check the cleanliness of the air blower
terminals connected to the control unit.
Remove the air blower cover and check
for foreign particles on the spinner or if
the scroll hits the cover during rotation.
Dismount the air blower in the
following order:
• Ensure access to the air blower
(if necessary, remove it from the
vehicle)
• Disconnect the air blower socket
• Remove the screws fastening the air
blower to the air blower housing
• Dismount the air blower
• Remove the screws fastening the
cover to the air blower housing
Visually inspect the spinner for for-
eign particles, clean if necessary. If the
foreign particles are hard to clear away,
remove the spinner from the motor
shaft. Remove the lock washer and dis-
mount the spinner. Pay attention to the
adjustment washers under the spinner.
Make sure not to lose them! Clean off all
foreign particles and install the spinner
back onto the motor shaft (with a new
lock washer).
If the spinner hits the cover, grind the
touch points on the spinner and the
cover with ne abrasive paper. Screw
the cover in and check whether the
spinner hits the cover once again.
Mount the air blower in the reverse
order. Visually check the condition of
O-rings.
