Disassembling the clutch cover

Remove the plug (3) with the O-ring (7), the engine oil pressure sensor (9) with the seal (8) and the plug (16) with the seal (17) from the cover.

Remove the snap ring (13) and withdraw the shim (12) and the seal (11).

The drilled bush (10) is forced onto the cover. Remove with a suitable puller.

Visually check the seal (11) and replace, if necessary.

Remove the above parts to check the seal (6) into the clutch cover, between the clutch housing and the primary gear (Sect. N 6.1, Disassembling the clutch).

Reassembling the clutch cover

If the bush (10) needs to be replaced, fully seat the new bush in the clutch cover with a suitable drift or a press.

If the seal (11) needs to be replaced, fit the new seal into the clutch cover. Its side with no spring should face the snap ring (13).

Before fitting the snap ring, ensure that its seat shows no burrs which might damage the seal.

Fit the shim (12) and the snap ring (13).

Caution

For proper sealing of the seal (11) the snap ring (13) should be free to rotate.

If the seal (6) needs to be replaced, fit the new seal into the clutch cover. Its spring side should face inwards (see figure). Lubricate seal lips with engine oil.

Fit the plug (3) and the O-ring (7). Fit the sensor (9) and the seal (8). Fit the plug (16) and the seal (17).

Refitting the clutch cover

Clean and degrease mating surfaces on clutch cover and casing and ensure that the centring bush (1) and the O-ring (2) close to the lubrication drill are fitted in the casing.

Apply an even solid bead of DUCATI sealing compound onto casing mating surfaces; avoid holes.

Lubricate the seal (6) with engine oil and fit the bush part no. 88700.5665 onto the primary drive gear so not to damage the seal while fitting the cover.

Fit the complete cover (14) onto the casing and fit the retaining screws.
