LUBRICATION GEAR HUB
Cleaning of parts:
• All parts – except for the planetary gear
carrier – can be degreased in a cleaning
bath.
• The planetary gear carrier only needs to
be cleaned on the outside with a brush
so as not to degrease the planetary gear
bearing.
Lubrication of parts:
Use only SRAM grease (Part No. 0369135 200/
...201) and standard bicycle oil.
• To lubricate the bearing points on
the planetary gear sets, position the
planetary gear carrier on its crown 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 through the axle bore and axle
slot, apply a thin coating of grease to the
outside.
• Oil the inside of the sun gears, grease
the outside teeth (fill the gaps in the
teeth).
• Oil outside teeth and carrier plate on
the coupling gear and lightly grease the
borehole from right and left.
• Do not apply grease to ring gear but just
oil the pawl pockets.
• Regrease ball retainer, line ball bearing
running tracks with grease.
Advice:
Do not use high-pressure water when
cleaning (e.g. strong water jets, high-
pressure cleaners etc.) – if water
penetrates it could lead to functional
problems.
BATTERY CHANGE
16,8 V NiMH battery
(see Fig. 8 and 9)
Disassembly:
• Apply fingertip pressure onto the tap and
pull battery cable plug off the battery
box.
• Turn quick releases to the „open“
position (Fig. 8) and pull them outward.
• Take off battery box from luggage
carrier.
• Unscrew the 4 bottom screws (slotted
screwdriver / Torx T10) and take off
battery box cover.
• Hang out stirrup (3, Fig. 9).
• Take out battery and pull off plug (1) and
cable shoe (2) from card modul.
Reassembly:
• Connect plug and cable shoe of new
battery to card modul:
– white plug with red and black cable (1,
Fig. 9)
– cable shoe with yellow cable (2)
and put battery inside.
• Assemble stirrup (3) (bulge downward).
Pay attention of correct cable routing
(Fig. 9).
• Mount battery box cover by the 4 screws.
• Pull both Quick Releases outward and
turn them to the „open“ position (Fig. 8).
• Position battery box onto luggage
carrier struts.
• Push Quick Releases inwards and turn
them to the „closed“ position (Fig. 8).
• Slide plug of battery cable in the slot of
the battery box until it snaps in.
Advice:
Use only batteries as specified by SRAM.
12 V lead battery
(see Fig. 10 and 11)
Disassembly:
• Apply fingertip pressure onto the tap and
pull battery cable plug off the battery
box.
• Turn quick releases to the „open“
position (Fig. 10) and pull them outward.
• Take off battery box from luggage
carrier.
• Unscrew the 4 bottom screws (slotted
screwdriver / Torx T10) and take off
battery box cover.
• Hang out stirrup (3, Fig. 11).
• Take out battery and pull off plugs (1+2)
from battery.
Advice:
Do not pull off any plug from card modul.
Reassembly:
• Connect plugs to new battery:
– black cable: Negative Pole (1, Fig. 11)
– red cable: Positive Pole (2)
and put battery inside.
• Assemble stirrup (3) (bulge downward).
Pay attention of correct cable routing
(Fig. 11).
• Mount battery box cover by the 4 screws.
• Pull both Quick Releases outward and
turn them to the „open“ position (Fig. 10).
• Position battery box onto luggage
carrier struts.
• Push Quick Releases inwards and turn
them to the „closed“ position (Fig. 10).
