Different versions of tensioning pulleys
  Note
t  There are 2 versions of tensioning pulleys installed, which can be exchanged.
t  The versions differ by the reverse direction of rotation when tensioning. During adjusting work, first check which version of tensioning pulley is installed and then ensure the correct rotation direction of the eccentric element when tensioning the belt.
Tensioning pulley A
t  Use the rig tool -T10265- for installing.
t  When installing, ensure that the peg of the base plate of the tensioning pulley is correctly positioned in the opening in the rear timing belt guard → Chapter.
t  Tensioning the timing belt is carried out by turning the eccentric element of the tensioning pulley »clockwise«.
Tensioning pulley B
t  It is not necessary to use a rig tool for installing.
t  The tensioning pulley does not have a peg on the base plate and is not tied up at the opening in the rear timing belt guard (its fitting position is free).
t  Tensioning the timing belt is carried out by turning the eccentric element of the tensioning pulley »anti-clockwise«.
