V-belt Tension
It is necessary to pay special attention to the routine maintenance and proper belt
tension adjustment because the V-belts on this machine transfer the engine torque
to the chipping wheel and the hydraulic pump.
For belt tension adjustment remove two side belt guards fixed here by fixing bolts.
Under these guards there is a belt gear for power transmission to the chipping
wheel and the hydraulic pump.
While tightening the belts proceed as
follows:
- Check up tension of new belts after
first 5 service hours and
afterwards always in intervals of
25 hours. Excessive slipping or
excessive tension will wear out the
belts prematurely and reduce their
life essentially.
- Adjustment of particular belts on the
hydraulic pump and on the chipping
wheel can be done independently.
- In case of three V-belts for the
chipping wheel it is necessary to
shift the belt pulley on the input
shaft.
- For adjustment of the belts for the hydraulic pump it is necessary to shift the
pump body.
