Overhaul
Servicing the front suspension-steering assembly,
described below, deals mainly with replacing parts
(pin- NADELLA roller bushings - sealing rings unit
and dust guard) which connect the steering tube
to the front wheel holder swinging hub.
N.B.
BEFORE PROCEEDING WITH THE DESCRIBED SERVICE,
CHECK THAT THE STEERING TUBE AND THE WHEEL
HOLDER HUB ARE IN EXCELLENT CONDITIONS: ONLY
THEN IS THE SERVICE JUSTIFIABLE.
MOREOVER, REMEMBER THE STEERING TUBE SHOULD
BE REPLACED WITH A NEW ONE WHEN DEFORMED.
