Maintenance and service
V-belts and V-belt pulleys
The illustration shows KS 475
– The V-belt pulleys are fastened to the shafts with the taper lock bushes. In order to
dismantle the V-belt pulleys, first loosen the threaded rod bolts ( 4 ) and screw them
out completely.
– Then screw one of the two threaded rod bolts into the bore ( 5 ). Tighten this
threaded rod bolt evenly until the clamping bush comes out of the hub.
– The washer moves freely now, the bush and the washer can be removed from the
shaft.
– Check whether the new V-belt pulley is correct and not damaged before fitting it.
The mounting area must be cleaned and degreased.
– Insert the clamping bush into the hub so that all holes overlap. Screw in the
threaded rod bolts ( 4 ) only by two threads at first, do not tighten them yet.
– Insert the feather key into the groove, then push the V-belt pulley with taper lock
bush into the desired position on the shaft. Make sure that both V-belt pulleys
are aligned with each other and do not rub against the protective cover after final
assembly.
– Now tighten the threaded rod bolts ( 4 ) step by step with a tightening torque of
92 Nm. Mount four V-belts and adjust the tension of V-belts ( See Page 81 ) cor-
rectly.
– Fit the protective cover and carry out a test run. After a running time of
30 to 60 minutes, check the tightening torque of the taper lock bushes.
