Hubs are provided with permanent
lubrication and maintenance-free under
normal conditions.
Cleaning of parts:
• All parts – except the planetary gear
carrier and the driver – can be degreased
in a cleaning bath.
• Planetary gear carrier and driver only
need to be cleaned on the outside with
a brush so as not to degrease the
bearings.
Lubrication of parts:
Use only SRAM grease (Part No. 0369 135 200/
...201) and standard bicycle oil.
• To lubricate the bearing points on
the planetary gear sets, position the
planetary gear carrier pawls upside and
apply 2 – 3 drops of oil to the bearing
bolts – at the same time turning the
planetary gears so that the bearing
points are completely wet. Oil axle slot,
apply a thin coating of grease to the
outside.
• Grease the teeth of the axle (fill the
gaps).
• Apply grease to gear ring teeth but just
oil the pawls and pawl teeth.
• Oil pawl carrier pawls and pawl
bearings.
• Oil cartridge bearing.
• Regrease ball retainers, line ball
bearing running tracks with grease.
Caution:
Do not use high-pressure water when
cleaning the gear hub (e.g. strong water
jets, high-pressure cleaners etc.) –
if water penetrates it could lead to
functional problems.
