6 Maintenance Requirements
6.1 Summary
The ALG graders have been designed predominantly utilising grease free SKF bearings and
bushes. This minimises the requirement for regular greasing of the main pivots and cylinder
clevises. Regular greasing is required for the Axle Hubs, Swivel Hitch, Apron pivot & Rocker
Pivots.
Although there are many locations where regular greasing is not required, regular inspections are
required. These help to detect early signs of wear or failure. Without regular cleaning and
inspections, wear or minor structural or non-structural defects could be allowed to increase or
spread and could result in catastrophic failure or injury.
6.2 Initial Maintenance Requirement
When the ALG graders are assembled, the hitch and hubs are already primed with grease
however it is the owner’s responsibility to check this prior to use.
6.2.1 Wheel Hubs
To ensure the hubs have sufficient grease to ensure long life, remove the inner grease nipple and
pump grease into the outer nipple. Continue to do so until grease comes out of the inner hole. Fit
the grease nipple back into the hub. Continue to do this for all hubs.
