Ducati Diavel Service Manual: Inspection of the gear selector drum

Ducati Diavel Service Manual / Engine / Gearbox assembly / Gearbox shafts / Inspection of the gear selector drum

Use a gauge to measure the clearance between fork pin and the slot on the selector drum.

If the service limit is exceeded, determine which part must be replaced by comparing these dimensions with those of new components (sect. 3 - 1.1, Gearbox).

Also check the wear on the drum support pins; these must not show any signs of scoring, burrs, or deformation.

Turn the drum in the crankcase to establish the extent of radial play. If play is excessive, change whichever part is most worn.
