GENERAL MAINTENANCE INFORMATION

Unless otherwise specified, moving parts, threads, O-rings and sealings must be greased before
assembly.

CLEANING
For an optimal result of the maintenance work, every component that will be disassembled must
be cleaned. Only use cleaners and degreasers which do not damage the components. Especiallythe cleaning of O-rings and sealings requires mild cleaners. Observe the instructions for use of therespective cleaner.
DT Swiss recommends the following cleaners:– Motorex Rex– Motorex Swissclean– Motorex OPAL 2400, 3000 OPAL, OPAL 5000
Use soap water or similar mild cleaners for external cleaning.

TOOLS
To ensure a damage-free mounting and dismounting of the components, only use the tools which
are mentioned in this manual. Special tools are indicated at the beginning of a chapter in the table"Required material".
The use of different tools is at the discretion of the user. If components are damaged by the usage ofdiffering tools, the user is liable.
DT Swiss special tools are precision tools. Damage-free mounting and dismounting of thecomponents can only be ensured if the tools are working properly and if the condition of the tools
are perfect. Always keep the tools in their original packaging or adequate devices to prevent
damage.

1.7

SERVICE INTERVALSDT Swiss recommends the following maintenance activities and intervals.
Task

Interval

Small hub service (function check, cleaning and greasing)
Under normal operating conditions
In case of extreme operating conditions (regular rides in dust, rain, snow, orin case of frequent transport while raining)

3 months
as required

Full hub service*(replacement of defective parts as required)

as required

Check the tightening torques

20 operating hours– Center Lock adapter: 40 Nm– Screws of the brake rotor: 6 Nm
Clean with soft cloth and a suitable cleaning agent

After each ride

→ Do not use a high-pressure cleaner, aggressive cleaning agents,
solvents or surfactants!
Check the hub for damage.

After each ride

SMALL HUB SERVICE
During the small hub service, the following activities should be performed:
1.

Dismount the end caps.

2.

Clean the end caps and the underlying surfaces of the ball bearings.

3.

Check the ball bearings.
→ The hub must turn smoothly.
→ The hub must not have any play in relation to the axle.
→ If there is play, or the ball bearings are running heavy or rough, a full hub service needs to be
performed.

4.

Grease the surfaces of the ball bearings.

5. Mount the end caps.

FULL HUB SERVICE
The full hub service must only be carried out if malfunctions are present or faults are detectedduring the functional tests.
The full hub service includes the activities of the small hub service and additionally the disassemblyof the ball bearings and assembly of new ball bearings as well as the disassembly of the complete
freewheel system and the exchange of the corresponding spare parts.

10. Remove the installation cylinder from the hub and remove the hub from the vise.
11. Put the non drive side of the hub with the axle
onto the installation cylinder.

12. Slightly grease the bearing and put it onto
the drive side with the colored side facing
outwards.

Front Wheel Hubs - Technical Manual2113. Attach the axle tool to the axle.
→ The axle tool centers the installation cylinder
on the ball bearing and thus prevents theball bearing from tilting during press-fitting.
14. Fit the installation cylinder onto the axle tooland ball bearing.

15. Drive the second bearing into the hub shell withslight hammer strokes.
16. Remove both installation cylinders from thehub.

17. Check the bearing.
→ The hub must turn smoothly.
→ The hub must not have axial play.
