Lubrication and Attachment of An 'Ahead Set' Stem To The Fork

Every year your bicycle should have a complete lubrication. This can be quite a complex task and may be best handled by a professional bicycle mechanic. However, if you feel capable the following procedure will guide you.

1.Suspend the bicycle so that the front wheel is off the ground.

2.Take the handlebar assembly from the steering tube.

3.Loosen and remove the compression bolt, the top cap assembly and then the stem clamp bolts.

4.Remove the headset wedge whilst supporting the forks with one hand, then remove the dust cover upper ball retainer.

5.Pull the forks out of the frame and remove the lower ball retainer.

6.Thoroughly clean and check each part of the headset for damage. Replace if necessary. (See your dealer to replace the headset).

7.Grease both the head set cups. To work grease into the lower head cup re-fit a ball retainer into it. Re-attach the forks.

8.Install a bearing retainer into the bearing race and pack it with grease. Push the screw cup down onto the fork steerer and into position then re-fit the bearing dust cover/ bearing race / headset wedge and spacer.

9.Alter the upper cup by hand until no movement can be detected in the forks.

10.Firmly tighten the stem clamp bolts, then replace and secure the handlebar assembly.
