When removing the bearing races from the headstock, the oil seals within the
headstock will get damaged and must be replaced.
Note the orientation of the dust seals for installation.
1. Remove the dust seal.
2. Remove the inner race and bearing from the headstock.
3. Using a suitable drift, evenly and progressively drive the oil seals and outer races
from the frame headstock.
4. Remove the bearing from the lower yoke.
5. Remove the outer race and dust seal from the lower yoke using a press or puller.
Headstock Bearing – Inspection
Only remove raised witness marks from within the frame. Removal of material below
any raised areas will reduce the level of interference between the frame and the
bearings. Loss of interference could cause the bearing to become loose in the frame
leading to loss of motorcycle control and an accident.
1. Examine the frame for any raised witness marks caused by the removal process.
Remove any such marks with fine emery paper or a suitable file.
Lower Yoke and Headstock Bearings - Installation
Make sure the motorcycle is stabilised and adequately supported.
A correctly supported motorcycle will help prevent it from falling.
An unstable motorcycle may fall, causing injury to the operator or damage to the
motorcycle.
