

Rams:

On top of this fit a large ring which faces as shown in fig. 8.
Finish with a small ring. Make sure that the rings are tight up against each
other.
Welled rings. Start with two rings which are bolted together as shown in fig.
9.
Fill the shaft until approx. 22 cm is left. Then finish with two rings bolted
together. Make sure that the rings are tight up against each other.
Insert the stoprings, fig. 22 pos. 53. The protruding shaft ends must be the
same length. This is achieved by striking the shaft. Tighten the stoprings
well. It is advisable to undo and tighten them several times so that the screws
can grip properly.
Then push the bearings onto the shaft ends.
Unfold the roller frame as described above under removal. Push the complete
shaft up against the frame. In the case of a crosskill roller, make sure that the
direction of rotation is correct as shown in fig. 8.
Fit the bearings and do up well. Remember to position the lubrication nipples
so that they can be lubricated, see fig. 10.
Tip the roller to the vertical.
THE SWING RAMS MUST NOT be operated before THE ROLLER IS
ALL THE WAY UP.
Swing rams (inner fig. 22 pos.46 outer fig. 23,24 pos. 67):
This can be done with the roller in transport or working position. The rams
must be unpressurised in both cases.
Disconnect the hoses. It is advisable to place a bucket underneath to collect
oil.
Take off the split pins and washers, then the ram can be removed. It weights
21 kg.
Assemble in reverse order. After assembly swing the side wings out and in
carefully a few times (see under operation) to get the air out of the system.
Check that the hoses can follow without getting caught, and that the
connections are not leaking.

REMOVAL:
1. Empty the oil from the ram, compressed air can be used to move the
piston rod back and forth, to press the oil out.
2. Place the piston rod in the middle position. Unscrew the gland (pos. 3) 30
mm out. If the gland can't be unscrewed, it may be necessary to warm it up
to 300c. Let it cool off slowly. With the gland screwed out, pull the piston
rod out towards the gland. Screw the gland all the way off, and the piston
rod can now be removed.
