T-ring flat steel crumbler cylinder. Replace gaskets
Fig. 24
DISMANTLING:
1.
Empty the cylinder of oil, (if necessary, use compressed air to move the
piston back and forth to push the hydraulic oil out).
2.
Drive the piston to the centre position. Locking ring (pos. 7) is removed
from the head at both ends. Push in the head a little, and the locking
ring (pos. 6) can be removed.
3.
Now, the head can be pushed out at both ends by pushing the piston
rod.
4.
The piston rod is pulled out entirely, and all gaskets can be accessed.
5.
The gaskets are removed, (if required, use an awl or screwdriver).
6.
All parts are cleaned and checked for chips, burrs etc.
MOUNTING:
1.
New gaskets are mounted.
2.
Piston rod is mounted together with one cap. It is pushed in far enough
so that the locking ring (pos. 6) can be mounted.
3.
The other head is mounted and is pushed in far enough so that the
locking ring (pos. 6) can be mounted.
4.
Carefully, start putting some pressure on in one direction, so that the
head protrudes enough for the locking ring to lock (pos. 7). Then, do
the same in the other direction.
5.
All cylinders are driven into stop both ways, in order to synchronize via
the valve (pos. 8-9-10-11).
