Position the gearbox drum selector fork in the centre of the gear rollers.
Position the gear selector lever (21) together with control shaft, spring and plate into the chain-side crankcase half.
Insert the screws (18) and (20) with the spacer (19).
Temporarily fit gear change lever (or a service lever) and engine pinion and shift to neutral gear.

Place the tool 88713.3334 On the gear claw.

Place the tool 88713.3334 Inserting the clutch rod (e) into the tool hole, block the pin (f) of the tool in the gear claw pressing with the hand in the point (g) (claw stroke lock plate) towards the right, as shown in photo.


Tighten the screw (18) in this position to a torque of 36 nm (min. 34 Nm - max. 38 Nm) and screw (20) to a torque of 16 nm (min. 15 Nm - max. 17 Nm) (sect. 3 - 3, Engine torque settings).
Warning
Make sure that the gear selector lever fixing screws (18) and (20) are those indicated in our spare parts catalogue. They Must be screws of class 12.9 In order to respect the tightening torque indicated above (sect. 3 - 3, Engine torque settings).
Start tightening the first screw (18), and continue with screw (20).



Remove service tool no.
Check that the pin (h) placed on the gear drum is axially to the notch (l) on the gear claw (with gear in neutral).

With the gearbox in neutral, check that the lever travel is the same when shifting up and down. The same should apply when a gear is engaged.
Operate the gearchange lever and turn the front sprocket at the same time to check that all the gears engage when shifting up and down.
Remove the previously installed lever and sprocket.
