OPERATING CYCLE

Removing (see Fig. 1)

• Fit the tool (1) flywheel lock n° 1.860.846.001 (Op. 1810A24)
• Undo the three bolts (2), at 120°, fastening the clutch drip tray.

Fig. 1

• Fit the centering device (3a) and the rest of the tool (3b) n° 1.871.003.100, tightening the bolts (3c) in the seats of the bolts removed previously.
• Turn the handwheel of the tool (6) until the pins (4a) come into contact with the disc (4b).
• Undo the remaining bolts (5) securing the clutch cover.
• Unscrew the handwheel (lever) of the tool (6) to discharge the clutch mechanism's diaphragm spring.

• Turn the handwheel of the tool (6) until the pins (4a) come into contact with the disc (4b).
• Manually tighten the three bolts (5) securing the clutch assembly using the special spanner to the end of travel position (without tightening to torque which will be checked later using a torque wrench).

The three bolts (5) must be fully tightened using the special spanner in order to ensure that the clutch is not retracted when the tool is later removed.

• Unscrew the handwheel of the tool (6) to discharge the clutch mechanism's diaphragm spring.
• Remove the tool.
• Manually tighten the remaining bolts fixing the clutch using a special spanner (as above).
• Gradually tighten, in diagonal order, the bolts securing the clutch unit until the recommended torque of 2.8 daNm is reached.
