Adjusting steering bearing play

Note

See Section D 4, Adjusting steering bearing 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.

Adjusting the steering angle

Loosen the nuts (11).

Loosen the adjusting grub screws (10) on both sides of the bottom yoke.

Take a 15 mm calibrated shim (A) and fit it on fork sleeve, in the top section, close to bottom yoke, or use a gauge.

Turn the front fork assembly to the right until the shim (A) contacts the frame upper tube.

Bring the adjusting grub screw (10) on the left side in contact with the end stop on steering head.

Apply threadlocker to the nut thread (11).

Hold the grub screw (10) steady and tighten the nut (11).

Rotate the front fork assembly to the left, repeat the procedure for the other dowel and tighten the nut.

Disassembling the steering tube components


Operations	Reference - See Section
Remove the handlebar and lower U-bolt	H 1, Removing the handlebar
Remove the headlight fairing	E 1, Removing the headlight fairing
Disconnect instrument panel from wiring	P 1, Arrangement of wiring on frame
Remove the fork legs	G 2, Removing the front fork (1100S) G 2, Removing the front fork (1100)

Note

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.

Remove the headlight mount (12), loosen screws (13) securing it to steering head (2).

Slide off headlight mount (12) toward vehicle front end and disconnect headlight wiring (Sect. P 1, Arrangement of wiring on frame).

Remove the headlight mount (12).

Loosen the screw (1) securing the steering head (2) to the ring nut (3).

Lift the steering head (2).

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

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

Slide bottom yoke (9) and steering shaft out of frame tube.

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.

Caution

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

Using a drift, remove the outer bearing rings (C) from the steering tube. Proceed with care. Do not damage the ring seats.

Refitting the steering tube components

Caution

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

Clean all contact surfaces and grease with the recommended grease.

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;

place the outer rings (C) of the bearings into the seats in the steering tube;

insert the fixed bush (D, with threaded bore) of the tool into the bottom ring;

fit the other bush (E, moving bush) into the upper end of the tool rod and push it against upper bearing ring;

screw nut (F) and use the wrench to push the outer rings (C) against steering tube;

leave tool assembled to steering tube until the latter has cooled down to ensure that bearings become fully seated in their seats.

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 120 °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 inner bearing ring (A) with the specified grease.

Fit the ball ring (B) into the steering shaft with the smaller side of the cage up and grease.

Fit steering shaft into steering tube and push until it becomes fully seated axially.

Install the bottom yoke (9) assembly to the frame.

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.

Fit the oil seal (4) with the flat face facing upwards.

Smear some grease onto ring nut (3) and tighten adjuster ring nut (3) finger tight until fully home on seal (4).

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. Reposition the fork legs as described in Sect. G 2, Refitting the front fork (1100S)/Refitting the front fork (1100).

Grease the screw (1).

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

Connect the headlight wiring (Sect. P 1, Arrangement of wiring on frame).

Refit the headlight mount (12), tighten the screws (13) to the specified torque (Sect. C 3, Frame torque settings).
