If you should want to just replace the shaft or bear-
ings, remove the key
(13)
and hit the shaft with a
plastic mallet on the pulley side in order to remove
the shaft together with the lower bearing
(14)
.
After having removed the snap ring
(15)
, the dust
cover
(16)
and the spline
(17)
, the bearing
(14)
splined onto the shaft can be removed using a nor-
mal extractor, taking care to close up the threaded
hole
(18)
with a screw to prevent the point of the
extractor from damaging the thread.
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
(19)
.
On reassembling, first put the shaft into the hole of
the lower bearing and insert this into the support.
Fit on the upper bearing and, using the special bush
# Cod. 60800030/0
(20) which works on the inner
ring
, hit it squarely with a mallet until the bearing is
fully driven home.
The right and left shafts seem to be the same, but
can be differentiated as follows:
–
right shaft
: red paint on the pulley side;
–
left shaft
: green paint on the pulley side.
Before refitting the support assembly, check that
these positions are correct.
Fit the flange supports onto the deck,
fully tighten-
ing the nuts (12)
.
