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 washer (24), the caliper mounting bracket (26) with the O-rings (25) and the other washer (24).

The rear hub is a component particularly critical to the dynamic safety of the motorcycle. For this reason, any overhaul of the internal components of the hub is strictly forbidden. The hub is available as complete assembly, part no. 756.2.006.2A.

Before refitting, apply the recommended grease to the seat on the eccentric hub (28) of the caliper mounting bracket (26) on which the rings (25), also greased, will be located.

Fit the caliper mounting bracket (with the 2 O-rings) on the hub, inserting the locating pin (11) on the swingarm in the slot on the bracket (26) as shown.

Apply the prescribed threadlocker to the bolts (12) and tighten to the specified torque (Sect. C 3, Frame torque settings).

Tension the drive chain as indicated in the paragraph “Adjusting the chain tension” in Section D 4.

Refer to the indications for checking swingarm bearing play in Section G 1, Wheel bearings.

Remove the eccentric rear hub as described in “Removal of the rear eccentric hub” in this section.

Roll the shaft on a reference surface and measure maximum distortion using a feeler gauge (see Sect. C 1.1, Rear wheel).

Inside the swingarm (1), at the point at which it pivots on the frame, there are a pair of ball bearing races (2) on the right-hand side and a pair of roller bearings (6) with seals (4) on the left-hand side.

Remove the bearings (2), the seals (4) and the roller bearings (6) using a suitable punch and a press. Support the swingarm and take care not to damage the bearing bores.

Heat the entire swingarm up to 150 °C and support it.

Insert the new roller bearings (6) in the service tool no. 88713.1068 and install them from the outside into the bore on the left–hand side of the swingarm.

Use the same tool to fit the new seals (4), positioned as shown in the sectional view, so that they seat against the newly installed roller bearings.

To install the ball bearing races (2) you will need service tool no. 88713.2409 comprised of:

Fit a new bearing (2) with the internal spacer (3) onto the drift (A) and position it on the interior of the right-hand side support of the swingarm.

Before refitting the swingarm (1), grease the ball bearings (2), roller bearings (6) and seals (4) with the recommended grease.

Locate the swingarm assembly (1), making sure that spacers (7) and (8) are present on the RH side and that the bush (5) is present on the LH side.

Tighten the nut (10) to the specified torque (Sect. C 3, Frame torque settings).

Fit the upper chain guard (17), feeding the drive chain through it; apply threadlocker to the bolts (15) and tighten them to the specified torque (Sect. C 3, Frame torque settings).

Reconnect the wiring connector (A) of the speed sensor and secure the rear brake fluid reservoir with the bolt (B) using the prescribed threadlocker.
