GENERAL GREASE POINTS
Regular greasing greatly improves the service life of the bushes and also removes any moisture which
may cause internal corrosion on the wall of the bosses making it difficult to remove the pivot shafts for
inspection.
LUBRICATION SPECIFICATIONS
It is recommended that only premium quality grease is used. Lithium based grease offer very good
performance. For the slew ring, the “RENOLIT ARMNA G4789” from Fuchs offers extremely good lu -
brication and anti corrosion properties especially at very low temperatures (-30°C).
SLEW DRIVE
To grease the slew ring, the machine needs to be set up and slew around to gain access to the reas-
sessed grease nipple fitted to the top face of the slew ring.
When greasing the worm housing, take care not to push out the oil seal on the end face. If you do, remove
excess grease from the end and drive the seal back in. Refer to the slew drive section for more details.
SLEW DRIVE GEARS
The slew drive gear is designed to be largely maintenance free. However, it is recommended that the
gear teeth be greased on a weekly/monthly basis with a high pressure grease depending on opera -
tion conditions. Always clean the gear firstly to remove any road dirt and grime. In very dusty or sandy
conditions, take care to prevent a build up of grit/sand mixed with grease which may cause pre-mature
wear on the gear.
Additionally, the ring gear and gear box should be greased on a six monthly basis. The grease nipple
