Bold reference numbers in this section identify parts not shown in the figures alongside the text, but which can be found in the exploded view diagram.

Remove the spacer (18) on the chain side and remove the wheel shaft (27) with the brake disc (26) and phonic wheel (30) from the opposite side.

The rear hub is a component particularly critical to the dynamic safety of the motorcycle. under no circumstances may the internal components of the hub be serviced or repaired. The hub may be ordered as a complete assembly, spare part No. 756.2.006.2A.

If they are to be renewed, unscrew the screws (33) from the wheel shaft (27) and remove the locating pins (32).

To check the wear limit of the brake disc refer to Sect. C 1.1, Hydraulic brakes.

Refit the rear brake disc (26), tighten the screws (34) and (33) to the specified torque (Sect. C 3, Frame torque settings).

Fit the phonic wheel (30) and fasten it by tightening the screws (31) to the specified torque (Sect. C 3, Frame torque settings).

If the calliper bracket locating pin (2) was removed during disassembly, apply the recommended threadlocker on reassembly, fit it on the swinging arm and tighten to the specified torque (Sect. C 3, Frame torque settings).

Before refitting, apply the recommended grease on the seat of the eccentric hub (17) on the calliper mounting bracket (16) on which the rings (15), also greased, will be installed.

Refit the other washer (14) and tighten the calliper mounting bracket (16) after installing circlip (19) in its groove (E) on hub, and setting it with its cutting edge outward.

Turn the eccentric hub (17) taking the horizontal axis (L) of hub hole (F) above the horizontal axis (G) of hub seat and at any rate until achieving the correct centre distance between hub hole (F) and swingarm pivot hole (H), as shown.

Fit the inner bush (18) on wheel shaft (27), and position it so as the taper end is facing the shaft, as shown, then tighten the screws (3) to the specified torque (Sect. C 3, Frame torque settings) according to a 1-2-1 sequence.

Fasten hose clips (25) to swinging arm, setting them as illustrated in the figure and then tighten the screws (24) to the specified torque (Sect. C 3, Frame torque settings).

Fit the rear brake calliper (A) over the brake disc, aligning it with the holes in the calliper mounting bracket. Grease the threads and undersides of the heads of the screws (B). Tighten the screws (B) to the specified torque (Sect. C 3, Frame torque settings).

Free the rear brake hose and the speed sensor wiring from the lower chain slider (8) and from the upper protection (13) and lower protection (12) by unscrewing the screws (9).

To replace the support bearings, refer to Sect. N 9.2, Reassembly of the crankcase halves.

Once the play in the swingarm bearings has been checked, the swingarm (4) may be removed from the motorcycle.

Hold nut (16) and tighten the screw (15) on swingarm shaft right-hand side.

Service limit: (0.3 mm) (Sect. C 1.1, Rear wheel).

The maximum permissible end float is 0.1 mm.

When a 0.10 mm feeler gauge or shim can only be inserted with difficulty, there is no need to install any further shims. Other­wise, use the two available shim sizes (0.20 mm and 0.10 mm) to obtain the specified end float.

NEVER install 0.1 mm shims on the left-hands side.

The left-hand side shim pack shall be max. 2 mm thick (1.8+0.2 max.).

Side-to-side movement of the rear end of the swingarm must be below 1 mm.

Smear grease on either side of shim (22) selected when checking the end float (see paragraph “Checking swingarm end float” in this section). Fit swingarm to engine with the selected shim (22) on the right-hand side.

Push the left arm of swingarm against engine and fit between the right arm and the engine the shim thickness (22) determined after measuring the end float.

Tighten the screw (15) to the specified tightening torque (Sect. C 3, Frame torque settings) while holding nut (16).

Tighten the screws (9) to the specified torque (Sect. C 3, Frame torque settings), observing the indicated sequence.

Fasten the rear brake hose and the speed sensor wiring to swingarm (4) installing the lower chain slider (8), the upper protection (13) and lower protection (12), and starting the screws (9) in their thread.

Tighten the screws (9) to the specified torque (Sect. C 3, Frame torque settings), observing the indicated sequence.
