Ducati Diavel Service Manual: Adjusting of the air-gap phonic wheel sensor

Ducati Diavel Service Manual / Chassis / Abs components maintenance / Adjusting of the air-gap phonic wheel sensor

(For front as well as rear sensor) in each case of maintenance that foresees:

It is necessary to check the air-gap between the speed sensor and the phonic wheel, once the components are refitted.

Place the appropriate number of shims (b) under the abs sensor so as to achieve 1.3 To 1.9 Mm air-gap between abs sensor and phonic wheel. When shimming is correct, a 1.3 Mm feeler gauge will fit between abs sensor and phonic wheel, whereas a 1.9 Mm will not.

Check at three equally spaced locations (spaced about 120 apart) of the phonic wheels (1) and (2). Shims (b) come in two sizes: 0.2 Mm and 0.5 Mm. Combine the shims as required to achieve correct shimming.

When checking with the 1.3 Mm feeler gauge (go gauge) and the 1.9 Mm feeler gauge (no-go gauge), the abs sensors (3) and (4) must be firmly secured in their seats. This means you need to loosen and retighten the sensor retaining screw fully home with its washer each time you add or remove any shims.

Warning

For the front wheel abs sensor (3), total shims used must never exceed 3 mm on the base version and 3.7 Mm on the carbon version.

For the rear wheel abs sensor (4), total shims used must never exceed 3 mm.

After shimming, tighten the retaining screws (5) and (6) of the sensors (3) or (4) to a torque of 10 nm +/- 10% (sect. 3 - 3, Frame torque settings) placing washers (7) and (8) in-between and check again using the 1.3 Mm feeler gauge (go gauge) and the 1.9 Mm feeler gauge (no-go gauge).

Phonic wheels cleaning

It is important to check that both phonic wheels (21) and (20) are always clean.

Otherwise: gently remove any possible dirt deposits with a cloth or metal brush. Avoid using solvents, abrasives and air or water jets directly on the phonic wheel (21) or (20).
