The recommended tow vehicle coupling height
is 385mm +/- 35mm from the ground to the
centre of the ball.
Off road vehicles are exempt from this
towball height specification.
Manufactured from high quality steel, the
chassis has extra deep sections to provide
strength at points of maximum stress.
Large elongated holes are punched in the
longitudinal and towbar (A frame) members,
to reduce weight to a minimum. Each hole
incorporates a return flange to maintain the
required strength and provide rigidity in the
extra deep sections.
The chassis frame is of a bolted construction
which, should the need arise, allows
replacement of individual parts.
The chassis is hot dipped galvanized. This
is regarded as one of the best forms of
corrosion protection. It does, however, require
maintenance in certain circumstances.
When new, the chassis is of a bright and
shining appearance. As the galvanizing cures
during the initial 2- 3-month period, this will
gradually change. During this curing period the
surface should be protected to avoid possible
wet storage stain, a soft, light coloured, porous,
oxidation layer. If the chassis members are
in contact with any salt deposits from roads
they should be washed off immediately with
a high pressure washer. Salt attracts moisture
allowing the surfaces to remain wet. This
prevents curing and also allows formation of
wet storage stain.
It is recommended that the chassis be washed
off, using a pressure washer, on an annual
basis (particularly after winter usage) to avoid
undesirable build up of salt and dirt deposits.
The galvanized chassis should not be painted
or subjected to any other protective treatment.
Should the galvanizing become superficially
damaged exposing the steel core, then it
should be cleaned and treated with a cold
galvanizing spray.
Damage to chassis members through impact
etc. must not be straightened or welded.
Damaged chassis members must be replaced.
The AL-KO rubber suspension is designed and
developed to suit all types of road conditions
and is maintenance-free. Three rubber
elements are contained within a hexagonal
axle tube. These provide suspension and have
inherent damping characteristics. (Only the
hubs and wheel brakes require attention, see
axle booklet Part No. 580458.)
The Euro Axle fitted to your Bailey caravan
comes complete with maintenance-free
wheel bearings greased and serviced for life.
Adjustment is not required during the design
life of the sealed bearing (100,000 km).
If replacement of the brake drum or shoes
is required, this must be carried out by
authorised AL-KO Service Centres. Specialist
tools and equipment are required. The rear
hexagonal bolt covered by a black plastic cover
must NEVER be touched.
