(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).


Bleeding of the abs hydraulic systemMain bearings
The main bearings have are of the angular contact type with offset inner
races so that the balls transmit loads from one
groove to the other along straight lines at an angle to the axis of the bearing.
The angle-contact ball bearings are
designed for bearing combined loading (radial-axial load ...
Overhaul of the gearbox
Check the condition of the front coupling dogs of the gears. They must be in
perfect condition and with no sign of wear on
the edges of the teeth.
The idler gears must rotate freely on their shafts.
When refitting, make sure the circlips are correctly positioned.
Check the needle roller ...
Accelerator position sensor (throttle grip)
Introduction
An accelerator position sensor (aps) is mounted on the throttle body of the
diavel, which measures the degree of aperture
of the throttle grip.
The throttle grip is connected to the sensor via two metal cables
The sensor transmits information to the ecu relative to the "torque ...
