Great Plains Uni-Press - Manual (Page 19)

DOUBLE DISC RING AXLE MAINTENANCE
The axles on this roller are tensioned by the main axle through the centre of the rings and
bearings.
SPECIALIST EQUIPMENT IS REQUIRED TO DISASSEMBLE THESE
AXLES, PLEASE REFER TO PARTS LISTINGS FOR DETAILS.
CONSULT YOUR APPROVED SIMBA DEALER UNDER ALL
CIRCUMSTANCES IF DISASSEMBLY IS REQUIRED FOR ANY
REASON.
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.
4.Check tyre pressures. Running the machine with tyres at the incorrect pressure may cause
excessive wear, overheating and possible failure.
