Raceway lubrication of the slewing bearing
Raceways must be lubricated at intervals according to
the actual operating conditions of the equipment.
It is recommended to grease the raceway every
50 hours of use. Before and after long periods of idle-
ness, the bearing must be greased again.
NOTICE
Make sure that the grease fittings are clean
before connecting the tool and applying grease.

4. Right side grease fitting for slewing bearing
NOTE : Two of the three grease fittings under the rear
edge of the dump body are connected to hoses that
bring the grease to four orifices around the slewing
bearing.
To grease the raceway, proceed as follows:
» Apply grease in each of the two grease fittings, the
center one and the right one. See previous figure.
» Then turn on the engine and perform one complete
rotation.
» Shutdown the engine and repeat the process one
more time.
Greasing is considered completed when the grease
overflows from the seal forming a light film, which also
has a sealing effect.
Raceway standard grease corresponds to :
Multi-season, lithium based, NLGI grade 1 EP rated
with "MOLY" additives, water resistant, minimum serv-
ice temperature of -40ºC to 100ºC (-40ºF-212ºF)
approved for automobile wheel bearing and chassis.
