washers proceed as follows
- Lubricate the sealing rings with mineral oil and
half fill the roller casings with Z2 grease.
- Insert the seal ring on the pin and the roller bush-
ing with wedging washers at the same time.
- Remove the specific tool and then the part 5

- Push, from the handgrip, the wedging washer -
roller casing - seal ring unit, placing part 16 until it

roller casing - sealing ring unit.

contact with the internal bottom of the roller cas-
ings) proceed as follows:
- Use the tool with part 20 and 21 fitted to the stem
as indicated in the figure.
- Push the two roller casings with the handgrip until
their bottoms make contact with the pin end.
- Use the specific tool fitted with parts 3 and 4 as
indicated for fitting the spin and push with the
handgrip until the washer is wedged in the swing-
ing hub.
- Remove the spacers, part 17, fill with grease the
area between the steering tube and the swinging
hub, and place the dust guard rings in that place.
