Fit the belt pulley
Note that the axle and the belt pul ley
have a profile that means that the belt
pulley must be turned cor rectly when
assembling.
Do not forget the washer between the
bearing and the belt pulley!
1. Fit the washer.
2. Fit the belt pulley on the axle.
3. Tighten the centre screw so that the
axle slides up towards the belt pulley and
the washer (A) is pressed between the
bearing and the belt pulley.
Tightening torque 28–31 lbf·ft/38–42 Nm.
Note: If the belt pulley is dismantled and
reassembled, before assembly the axle
must be driven down approx. 1 mm to
obtain the position as per paragraph 3
above.
Bearing housing/blade guard
Check that the rubber seal is fitted
properly against the bearing housing and
blade guard.
Turn the bearing housing so that the
screw hole becomes accessible from the
top with the tool.
Tighten the three screws crosswise so that
the washer is not unevenly loaded and
risks being deformed. Tighten the screws
fully.
Fit the seal with spacer ring.
Centre bush
Never hit the centre bush into position,
the axle will then be offset!
Fit as follows:
1. Position the inner flange washer.
2. Position the centre bush.
3. Fit the screw for the blade's attach-
ment.
4. Press down the bush until the screw
bottoms.
5. Dismantle the screw and place it on
the other flange washer “turned the
wrong way”. Refit the screw and press
down the bush against the inner flange
washer.
6. The bush is fitted.
