Check that the splines of the gearbox secondary shaft and the sprocket are in perfect condition.
Fit the engine pinion (14) on the gearbox secondary shaft by orienting it as indicated. Install the safety washer (13).
Tighten the nut (12) to the torque of 186 nm +/- 5% (sect. 3 - 3, Frame torque settings).
Bend the washer (13).

Fit the chain and close it using the tool with code 88713.1344 That was used to open the chain.
The tool is composed of a holder (a), punch (b), body (c) and two wrenches (d) and (e) and link plate holder (f).
Connect the two halves of the chain with the external link and manually fit the plate onto the pins.
Warning
Lubricate the pins abundantly; try to avoid touching them with your hands.
Fit the holder (a) onto the external link.
Fit the punch (b) into the body (c) and the plate holder (f).
Fit the body (c) onto the holder (a) which holds the chain in position.
Manually turn the bolt (g) until the plate holder (f) is seated against the plate itself.
Use wrenches (d) and (e) to turn the bolt (g) clockwise until the chain pin is in contact with the holder (f).
Remove the holder (a) from the tool.
Manually turn the bolt (g) until the punch (b) locates against the pin, taking care that they are aligned with each other.
Use wrenches (d) and (e) to turn the bolt clockwise until the punch (b) is seated against the chain plate.
To complete reassembly, repeat the entire procedure with the second pin.
Warning
Carefully check the two pins: the figure shows the correct result of the procedure.


Adjust the chain tension (sect. 4 - 3, Adjusting the chain tension).
Apply the recommended threadlocker to the screws (11).
Fit the sprocket cover (10) tightening the screws (11) to the torque of 6 nm+/- 10% (sect. 3 - 3, Frame torque settings).
