Fitting/removing poly-V-belts

Insert the 15 mm socket, with the handle
and extension attached, into the tensioner.

Swing back the tensioner.

Check that both the tensioner and the belt
pulley are in fault-free condition. Check for
such defects as worn bearings in the ten-
sioner, tensioning pulley and guide pulleys
and for wear of the tooth profile on the belt
pulleys.

Replace faulty parts.

Route the new poly-V-belt over all belt pul-
leys except the tensioning pulley (observe
the poly-V-belt routing shown in the illus-
tration).

Remove the spanner and check for correct
seating of the poly-V-belt on the belt pul-
leys.
