IMPORTANT
When refitting the plates (512),
the
holes correspon ding to the support axes must
meet perfectly in the centring step
(32) cut into the
upper part of each support.
Reassemble the blades.
Reassemble the blade control belt.
The second bearing still in place must be removed by
hitting it from the inside of the flange using a
12 ÷ 15 mm diameter round bar (30).
On reassembly, having first inserted the shaft in the lo-
wer bearing hole and inserted everything into the sup-
port, fit the upper bearing using the specific stopper
(31) that acts on the inner ring, hitting it squarely with
a mallet until the bearing is fully driven home.
Refit the flanged supports onto the deck, fully tighte-
ning the nuts (22).
B) Replacement of the bearings and the shafts
of the blades
Re mo ve the key (23) and hit the shaft on the pulley
side with a plastic mallet to extract the shaft together
with the lower bearing (24).
After having removed the key (25), the snap ring (26)
and the dust cover (27), the bearing (28) splined onto
the shaft can be removed using a normal ex trac tor,
being careful to close the threaded hole (29) with a
suitable screw to prevent the tip of the ex trac tor from
damaging the thread.
