DISMANTLING THE CRUSHER
Remove the gravel and stones from above the
slip ring, so the main shaft can freely move
down.
Lower the main shaft by opening either the
magnetic valve (A) or the manual needle valve
(B) located in the lubricating and adjusting
equipment (figure 8.2.1). When the main shaft
is in its lowest position, close the valve.
Remove the bolts from the feeding chute and
lift the chute (400 kg / 880 lbs) away. The
standard chute has 8 bolts, M20/keyhole 30
mm.
Remove sand and stones from above the top
bearing housing cover. Remove the bolts from
the top bearing housing cover, 4 bolts (A,
figure 8.2.2) M20/keyhole 30 mm, and lift the
cover (100 kg / 220 lbs) away.
Remove grease from the upper part of the top
bearing housing (figure 8.2.3).
Remove the bolts between the intermediate
and lower frames, 20 bolts (B, figure 8.2.2)
M36/keyhole 55 mm (figure 8.2.2).
Separate the intermediate and lower frame by
using the four jacking bolts (C, figure 8.2.2)
(M48/ keyhole 75 mm). The separation can be
helped by mounting lifting ropes on the upper
frame and tensioning them with the crane. In
this case leave three equally distributed bolts
(B, figure 8.2.2) loose in the frame connection.
Screw the nuts on the bolts so that the
connection can open about 10...20 mm
(1/2"-1"). This ensures, that the upper and
intermediate frame cannot jump away.
