Operating Instructions
5. Servicing and Maintenance
5.5 Double Disc Axles
The axles on this roller are tensioned by the
main axle through the centre of the rings and
bearings.
Specialist equipment is required for the
disassembly of Double Disc axles. Please
consult your dealer under any circumstances
that require disassembly of these axles.
Maintenance of these rollers is limited to daily
greasing of the bearings to flush out dirt, and
regular inspection to ensure the assemblies
are tight, and scrapers are correctly set. The
axles can be tightened provided the bearing
pillar ‘U’ bolts are loosened to avoid
preloading the bearings as they move
sideways to each other. Ensure the bearing
pillars are re- tightened to the mainframe after
this.
5.6 Wing Pitch
On SL700 Models, the pitch of the wings can
be altered by using the threaded ends of the
wing cylinders. Tightening the will raise the
outer tips of the wings and loosening wil lower
the outer tips.
5.3.2 Bearing Seals
It is important when replacing the labyrinth
type bearing seals in disc hubs that the seal
is fitted the right way round. The chamfered
lip side should be at the outside of the bearing
housing, nearest the disc arm (see Fig. 5.02).
This chamfered lip prevents dirt ingress into
the housing and also allows grease to be
flushed though when greasing.

5.4 Terra-Grip Tine Points
Tine maintenance should be
performed with the machine fully
raised and with all taps closed.
When working under the machine
ensure that the tractor handbrake
is on.
When changing points on Terra-
Grip tines extreme care should be
taken. Wear goggles at all times
when changing tine points.
5.7 Brakes & Wheel Hubs
The brakes should be tested before using for
the first time and after the first laden journey.
Check that the road and parking
brakes operate and release
correctly before using the machine.
Check for hydraulic fluid and air
leaks.
Brake and wheel hub maintenance
and servicing should be carried out
by an authorised Simba dealer.
