Caution
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.
Removing the rear eccentric hub
The components listed below must first be removed to allow removal of the rear eccentric hub.
Loosen the screws (12).
Remove the spacer (34) on the chain side and withdraw the swingarm shaft (28) together with the brake disc from the other side.
Unscrew the retaining screws (21) of the bracket (33) and remove splash guard (32).
Remove the circlip (23) on the side of the eccentric hub facing the wheel.
Remove the washer (24), caliper plate (26) with O-rings (25) and the other washer (24).
Withdraw the eccentric hub (28) from the chain side of the swingarm.
Caution
The rear wheel hub is a critical part for motorcycle dynamic safety and must not be disassembled; the complete spare hub is available under part no. 756.2.006.2A.
Refitting the rear eccentric hub
Reverse the disassembly sequence. Pay particular attention to the indications given below.
On refitting, apply recommended grease to the seat for the rings (25) in the eccentric hub (28) of the caliper plate (26); the rings must also be greased before installation.
If you have removed the reference pin (11) of the caliper plate, apply the specified threadlocker on refitting.
Refit the washers (24) with the sharp edge facing the eccentric hub.
Apply the specified grease to the screws (12) and tighten to the specified torque (Sect. C 3, Frame torque settings).
 
Adjust chain tension as described under “Adjusting chain tension” in Sect. D 4, Adjusting chain tension.
Removing the rear swingarm
The components listed below must first be removed to allow removal of the swingarm.
Disconnect the shock absorber and the linkage from the swingarm
With the swingarm (1) still connected to the frame, you can check for play in the bearings.
Rock the rear end of the swingarm (1) forward and backward and from side to side.
Exceeding movement indicates that the bearings are worn; worn bearings may affect vehicle handling.
For bearings clearance, please refer to Sect. G 1, Wheel bearings.
Remove the rear eccentric hub as described under "Removing the rear eccentric hub" in this section.
Release the rear brake line from lower chain slider (16) and heat shield (22) and release speed sensor cable by loosening screws (15) and (21).
Disconnect the speed sensor (A) from the main wiring.
Loosen nut (10) and slide out swingarm shaft (9) using a suitable tool.
Remove swingarm (1) from its seat and remove bushing (5).
Where swingarm attaches to the frame, on the right-hand side, there are two inner spacers (8) and (7).
Disconnect the connector (A) from the speed sensor.
Remove screw (B) securing the rear brake reservoir.
Swingarm shaft inspection
Measure the amount of distortion before refitting the swingarm pivot.
Rotate the pivot on a reference surface and measure distortion with a feeler gauge (Sect. C 1.1, Rear wheel).
Replace shaft when distortion exceeds the specified limit. Replace any cracked or distorted shafts.
Overhauling the rear swingarm
There are two pairs of bearings fitted inside the swingarm (1) at the pivot points in the frame. Namely, there are two ball bearings (2) on the right side and two needle roller bearings (6) with seals (4) on the left side.
To replace the bearings:
Remove the spacers (8) and (7) fitted on the right side of the swingarm and the bush (5) placed on the left side.
Remove ball bearings (2), seals (4) and needle roller bearings (6) with a suitable drift and a press. Support the swingarm adequately and make sure not to damage the seats in the swingarm during removal.
Caution
Do not reuse the bearings (2), seals (4) and needle roller bearings (6) after removal.
Heat the swingarm evenly up to 150 °C and place it on an adequate stand.
Insert new needle roller bearings (6) on the drift no. 88713.1068 and fit them from the outside into the seat in the swingarm left side.
Push the drift fully home into the swingarm.
Use the same drift to fit new seals (4). Arrange the seals as shown in the cross-section view and push them into firm contact with the needle roller bearings.
To install the ball bearings (2), use the tool no. 88713.2409, which consists of:
(A) - drift for inner bearing;
(B) - drift for outer bearing;
(C) - guide pin.
Fit a new bearing (2) and the inner spacer (3) on the drift (A) and place it on the inner side of the right side support of the swingarm.
Insert the guide pin (C) into the bearings you have already installed and slip its end into the inner hole of the drift (A).
Drive the bearing (2) fully home into the swingarm.
Fit the other new bearing (2) on the outer end of the drift (A).
Hold the assembly steady with the drift (A) and use the drift (B) to push the outer bearing into firm contact with the spacer (3). Remove the tools.
Before refitting the swingarm (1), lubricate ball bearings (2), needle roller bearings (6) and seals (4) with the specified grease.
 
Refitting the rear swingarm
If swingarm was disassembled, reassemble making reference to the exploded view at the beginning of the section.
Set the complete swingarm (1) in position; ensure that spacers (7) and (8) are in place on the right-hand side and bushing (5) is on the left-hand side.
Smear swingarm shaft (9) with recommended grease and push fully home in the frame.
On the shaft opposite side, smear nut (10) with recommended grease and tighten it.
Tighten the nut (10) to the specified torque (Sect. C 3, Frame torque settings).
Install the upper chain guard (17) and route chain through it, fasten the chain guard using the screws (15); apply threadlocker and tighten to the specified torque (Sect. C 3, Frame torque settings).
Connect speed sensor connector (A) and fasten rear brake reservoir using screw (B), after smearing it with recommended threadlocker.
 
Connect the shock absorber and the linkage to the rear swingarm
