Bold reference numbers in this section identify parts shown in this exploded view diagram. These parts do not appear in the figures near the text.

See Section D 4, Adjusting steering bearings play, for steering bearing play adjustment.

If the problem persists, inspect the steering bearings (5) and (6) for wear and replace as required. The replacement procedure is detailed in paragraph "Disassembling the steering tube components" in this Section.

Insert a 6-6.5 mm calibrated feeler gauge (A) on the fork sleeve, or use a gauge.

All components installed to steering head and bottom yoke, including electrical cables and Bowden cables, may be left in place, as long as they do not impair the disassembly procedure.

Loosen the ring nut (3) with the tool no. 88713.1058 and undo from the steering shaft.

Remove seal (4), bearing inner ring (A) and ball ring (B) of the top bearing (5) from steering shaft.

Withdraw the ball ring (B) of the bottom bearing (6).

The inner ring (A) and seal (7) of the bottom bearing (6) remain on the steering shaft.

Remove inner ring (A) and spacer (8) from the steering shaft using an all-purpose puller (see figure). Do not damage the seat.

Do not refit oil seals (4) and (7) and bearings (5) and (6) once they have been removed. Always fit new components.

Steering bearings (5) and (6) are identical, however, never mix their components.

Use the tool no. 88713.1062 to fit the outer rings (C) of bearings (5) and (6) onto the headstock. Proceed as follows:

heat steering tube up to 150 °C;

Fit the washer (8), the seal ring (7) with trim side up and the inner ring (A) of the lower bearing (6) into the steering shaft. Heat it up at 125 °C for ten minutes first.

Fit the drift no. 88713.1072 into the steering shaft. Keep the inner ring (A) pressed onto seal (7) manually for at least 10-15 seconds.

Grease the ball ring (B) and fit it to the top outer ring (C) of the frame.

Fit the inner ring (A) of the upper bearing (5) onto the steering shaft; its larger side should be face up.

Position the special bush no. 88713.1058 onto the ring nut (3) and then fit the torque wrench on the bush.

Tighten the adjusting ring nut (3) to the specified torque (Sect. C 3, Frame torque settings).

Install the steering head (2) to the ring nut (3) so that the fork leg clamp holes match those in the bottom yoke. Refit the fork legs as described in Sect. G 2, Refitting the front fork.

Tighten the screw (1) on the steering head to the specified torque (Sect. C 3, Frame torque settings).

If removed, fit the splashguard (13), apply threadlocker to the screws (10) and tighten them to the specified torque (Sect. C 3, Frame torque settings).
