Maintenance
Checking bottom bracket clearance
Risk of damage to the bearings.
- Never try to remove the bearing seals from the bottom bracket.
- Your THM bottom bracket is elaborately sealed and provided with permanent
lubrication. There is no need to re-lubricate the bearings!
- Grasp both cranks of your bicycle.
- Try to move the cranks to the left and right.
- If you feel bearing play, it means that the bottom bracket is loose and needs to be
adjusted immediately
- see Adjusting the bottom bracket , page 21.
- Now shift the chain onto the smallest chainwheel.
- Remove the chain from the chainwheel and place it onto the bottom bracket
housing.
- The bottom bracket can now be rotated freely.
- Use two fingers to grasp one of the cranks directly by the bottom bracket axle and
rotate the axle in its bearing.
-
If the bottom bracket axle rotates with perceptible resistance, it means that the
bottom bracket is too tight and must be adjusted immediately – see Adjusting
the bottom bracket , page 21.
