View G-G

Note: This adjustment should be made before any system pressures are adjusted.

Use the following procedure in order to tighten two bolts (21) :

1. Remove the cover (16) and loosen the bolt (21) .

2. Move the clutch lever (14) until the roller (17) is in contact with the plunger (18) .

3. Move the spring assembly (20) until the pin of the spring assembly is in the front detent of the clutch lever. See illustration 3.

4. Tighten the bolt (16) to 47 ± 7 N·m (35 ± 5 lb ft).

5. Repeat step 2 through step 4 for the other clutch lever.

6. Install the cover (16) .
