the roller shaft stays down on the ground.
ASSEMBLY:
Cambridge rings. Fit a stop ring about 12 cm in along the shaft (see fig. 3). Then start
with a smooth ring with the "nose" pointing outwards (see fig. 3), and follow with a
serrated ring with the smooth side facing inwards. This must be pushed right in on
the boss ("nose") of the smooth ring. Fill the shaft up in this way until a space of
about 12 cm is lefl. Omit the last serrated ring and finish with a stop ring.
Crosskill rings. Fit a stop ring about 12 cm in along the shaft (see fig. 4). Start with
a small ring, then fit a bush, and a large ring above this, the spokes of which run
the same way as on the first ...... And so on, finishing with a small ring and a stop
ring.
Welled rings. Fit a stop ring about 12 cm into the shaft. Start with two rings, screwed
together as shown in fig. 5. Fill the shaft until a space of about 22 cm is lefl. Close
off the shaft with two rings bolted together and a stop ring.
Loosen the stop ring screws. The projecting shaft ends must be of equal length. This
is achieved by striking the shaft. Make sure that the rings are very tightly packed.
Tighten the stop rings well. It is recommended that the screws be tightened and
loosened a few times to ensure that they grip well.
Then push the bearings in along the shaft ends.
Open up the roller frame as described above under 'Dismantling'. Push the whole
shaft into the frame. If it is a crosskill roller, ensure that the direction of rotation is
the same as shown in fig. 4. Mount the bearings and tighten securely. Remember to
tum the grease nipples so as to allow for
lubrication (fig. 6).
Raise the roller to the vertical position, using the single-acting valve. The
V
DOUBLE-ACTING VALVE MUST NOT OPERATED until the
single-acting valve is fully extended.
Rams:
Folding ram:
This can be done with the roller in either the transport or the operating position,
where the ram is in both instances pressureless; but the operating position is
recommended.
Remove the hoses. It is recommended that a bucket be placed undemeath to
catch any oil. Remove split pins and washers. The ram, weighing 21 kg, can be
dismounted also.
