6.2.5 Replace sprocket wheel, upper end
Find the conveyor plate with a coloured dot marked on it and move this
conveyor plate to the upper end of the Spiral Elevator. Under this conveyor
plate there is a locking link that can easily be removed.
Tools
. Danger: Make sure that the main switch has been switched off,
and safely isolated.
Procedure
• Remove the conveyor plate with the coloured dot. Under this
conveyor plate there is a locking link and the metal chain can be
separated here. The sprocket wheel is now released from the
chain.
• The gear motor should be dismounted from the shaft. This is done
by removing the bolt mounted in the hollow shaft of the gear motor
and after this the bolt that is connecting the torque arm with the
Spiral Elevator should be loosened. The gear motor can then be
removed.
