8.2.17 Renewing the poly v belt and checking the function of the switch-off
unit
NOTICE
When changing the belt:
▪ Always check the function of the switch-off unit. The switch-
off pin must emerge by spring force, or else the machine will
not switch off automatically if the belt tears.
▪ If the grooves are broken off or bent, renew the damaged
pulley.
▪ To be absolutely sure that you order the right poly v belt – in
terms of the length – it is recommended that you measure
the diameter of the fan-side pulley and use this as the basis
for your selection.
Belt types
Because of the different diameters of the fan-side pulleys, in combination
with different engine types and versions, various lengths of poly v belts are
used.
