5.3.3 Reassembly
Simba recommend that the seal and the inner
bearing are assembled on the spindle (as per
Fig. 5.03b) before inserting it into the housing
and reassembling the unit.
5.4 DD Light Roll
The axles on this roller are tensioned by the
main axle through the centre of the rings and
bearings. The DD Light roll is tensioned by
the end plates at the outer ends of the and by
the rubber spacers between each ring.
Specialist equipment is required
for the disassembly of DD Light
rollers. Please consult your dealer
under any circumstances that
require disassembly of these
axles.
Maintenance of these rollers is limited to
yearly/end of season greasing of the bearings
and regular inspection to ensure the
assemblies are tight, and scrapers are
correctly set.
The scraper is intended to clear dirt
from blocking between adjacent DD
rings. If adjustment to the scrapers
is required ensure that the metal
scraper cannot contact the rubber
spacer even under load. Regularly
inspect the rubber spacers for signs
of wear and adjust any scrapers to
ensure no contact can be made.
5.3.2 Bearing Seals
It is important when replacing the labyrinth
type bearing seals in X-Press disc hubs that
the seal is fitted the right way round. The
chamfered lip side should be at the outside
of the bearing housing (see Fig. 5.03a). This
chamfered lip prevents dirt ingress into the
housing and also allows grease to be flushed
though when greasing.
