Coupling
Couplings should be regularly checked
for any sign of loose bolts connecting the
coupling to the chassis as the two leading
bolts on the coupling are always under
a lot of strain. It is important that these
bolts be regularly checked to ensure that
they are tight. It is not advisable to grease
the ball of the coupling as this can lead
to a build-up of dust and thereby create a
significant wear due to abrasion. A silicone
spray will be sufficient lubrication for the
ball. Light machine oil will also be effective
without accumulating dust which could
cause excessive wear. Please refer to the
manufacturer’s manual provided for more
information.
Jockey wheel
It is possible to grease the internal thread
of the jockey wheel. This can be done by
removing the jockey wheel so that the top
section of the jockey wheel comes away
from the bottom tubular section and you
can grease the internal thread of the jockey
wheel.
Chassis
It is advisable to have a thorough annual
check of the chassis on your caravan. This
includes the running gear, suspension,
tyres, wheels, and brakes and coupling. The
chassis is such an important part of your
caravan you cannot afford to overlook its
general maintenance and service.
Chassis galvanising
The chassis on your unit has been
galvanised to provide a thick tough metallic
zinc coating which is bonded metallurgically
to the steel base. It completely covers the
steel and protects it from corrosion in
normal environments. The metallic zinc
used in the galvanising process provides
long-term protection; however, owners
should regularly maintain the chassis
which involves promptly washing off
any potential contaminants with clean
water. Obvious contaminants are chloride
and sulphur compounds, including salts
from sea, air and soil. Such contaminants
can cause permanent staining of the
galvanised finish, for which Talvor cannot
be held accountable. Natural ageing of the
galvanised coating will turn the chassis to a
grey colour.
