Ducati Scrambler 800 - Service manual > Fork - steering head: steering assembly

Refitting the steering tube components

Important The steering tube bearings are identical but in no case may their components be swapped during refitting.

Clean all contact surfaces and lubricate with the recommended grease.

To fit the outer rings (C) of bearings to the steering tube, use tool (B) no. 88713.1062. Proceed as follows:

heat the steering tube to 150 ºC;

• fit the outer rings (C) (upper and lower) in their seats on the steering tube;
• fit the fixed bush (G, with threaded hole) of the tool into the lower ring;
• fit the other movable bush (H) into the upper end of the tool and drive it fully home against the upper bearing race;
• tighten the nut (L), and use a wrench to seat the outer rings (C) fully in the steering tube;
• leave the tool fitted until the steering tube has cooled down to ensure that bearings are properly seated.

Fit spacer (9), dust seal (8) (with the rim facing upwards) and inner ring (7) of the lower bearing onto the steering shaft after heating it for about 10 minutes to 120 ºC.

Insert drift no. 88713.1072. Push the inner ring (7) on dust seal (8), manually pushing for at least 10- 15 seconds.

Lubricate the inner ring (7) with the recommended grease. Fit the ball race (6) on the steering shaft with the smaller diameter of the cage facing upwards, and grease the ball race.

Fit the bottom yoke assembly to frame.

Fit the internal ring (3), the ball race (4) and the external ring (2).

Position ring nut (1) and tighten it to the specified torque.

Refit the following components on the vehicle:

• Forks (Refitting the front fork);
• Handlebar (Refitting the handlebar);
• Front wheel (Refitting the front wheel).
