Ducati Diavel Service Manual: Overhauling the front wheel

Ducati Diavel Service Manual / Chassis / Front wheel / Overhauling the front wheel

Wheel bearings

Before checking the dimensions, check the wear on wheel bearings. Check for wear by hand after cleaning and degreasing the bearings in their seats.

Turn the inner race.

Check the amount of radial and axial play. Excessive play will cause vibration and make the bike unstable.

Overhauling the front wheel


To remove the bearings (5) and the sealing rings (4) from the wheel hub follow the instructions below.

Position a drift (a) against the inner race of the bearing (5).

Tap with a hammer until knocking out the bearing (5).

Apply the drift at different points to keep the bearing square during removal.

Overhauling the front wheel


Important

Once removed, the used bearings and sealing rings must not be refitted.

Before fitting new bearings, check that the housing is clean and free from scoring and damage.

Grease the bearing seat and then push the new bearing into its seat.

Using a tubular drift (b) that only bears on the outer race of the bearing, drive the bearing (5) fully into its seat.

Overhauling the front wheel


Use the same method to install the sealing rings (4).

Ensure that spacer (7) is fitted between the two wheel bearings.

Note

Wheels must be rebalanced after repair, maintenance and overhaul operations.

Inspecting the wheel axle

Check the wheel shaft for straightness.

Turn the pin on a reference surface and measure maximum distortion using a feeler gauge (see sect. 3 - 1.1, Front wheel).

Inspecting the wheel axle


Overhauling the wheel

After you have checked the bearings, check the rim as follows.

Visually inspect the wheel for cracks, scoring and deformation; change the wheel if damaged.

Insert the shaft in the wheel and mount it on two fixed reference blocks.

Using a dial gauge, measure rim run-out and out-of-round relative to the pin axle (see sect. 3 - 1.1, Front wheel).

If the values measured are not within the tolerance limits, renew the wheel.

Removal of the front wheel
Support the bike so that the front wheel is raised from the ground. Remove the front brake calliper (b) by unscrewing the two screws (a) securing the calliper to the fork leg; do not disconnect ...

Refitting the front wheel
When all the necessary inspections have been completed, refit the wheel as follows. Fit the spacers (3) and (9) to the seal rings on the sides of the wheel hub. Install the complete whee ...

Main 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 ...

Refitting the gear interlock plunger and pawl assembly
On the special screw (3), fit the gear pawl lever (4), orienting it as shown in the figure, the washer (2) with the square edge side (d) facing the clutch-side crankcase half, and the spring (1), positioning it so that the hook end (a) is facing the gear pawl lever. Locate the hook end (a) of ...

Chain lubrication
The chain fitted on your motorcycle has o-rings that keep dirt out of and lubricant inside the sliding parts. So as not to damage these seals when cleaning the chain, use special solvents and avoid aggressive washing with highpressure steam cleaners. After cleaning, blow the chain dry with ...
