AL-KO CHASSIS & TYRES
GENERAL NOTES ON
MAINTENANCE
Tyre Wear and Damage
The legal requirements for tread depth on
motor vehicles apply also to caravans. In
order to equalise wear it is suggested that
wheels be balanced and changed around
from time to time.
It is dangerous to neglect tyre damage and
should you detect a blister, rupture or cut
exposing the casing, or if it has suffered a
violent impact (for example against a kerb),
such that there is a risk of internal damage, it
is advisable to have it examined by a tyre
specialist as soon as possible.
Wheels
The condition of wheels should be checked
regularly particularly for distortion of flanges
and the wheel dish. Wheels damaged or
distorted, or having wheel bolt seatings
cracked or deformed must not be repaired.
Couplings
1. Clean and grease spherical seat, bearing
parts and pivot pins regularly.
2. Thoroughly examine all moving parts for
wear and correct functioning.
3. Couplings should never be drilled.
Towing Ball
The automobile towing ball should measure
50mm maximum and 49.5mm minimum (DIN
74058). If the ball is found to be worn it
should be replaced immediately.
Overrunning Device
The device housing is packed with grease on
assembly, but will require periodic
maintenance to ensure smooth operation of
the braking system.
1. Regrease the shaft bearings via the
grease nipples provided at 3000 mile
intervals and before storage.
2. Ensure correct functioning of all pivot
pins and levers and oil regularly.
Jockey Wheel
Lubricate wheel and screw thread
periodically.
Brake Linkage
All moving parts should be lubricated
periodically to ensure their satisfactory
operation.
It is recommended that all brake linkage
threads are liberally smeared with grease for
protection and as an aid to future adjustment
of the system.
Corner Steadies
The screw and pivot pins should be
lubricated periodically to ensure their
satisfactory operation.
Braking System
At 500 miles then every 3000 miles or 1 year
check and adjust brake linkage to
compensate for any stretch of the bowden
cables.
Check and adjust wheel brakes to
compensate for wear.
IMPORTANT: When replacing the wheels
you should tighten the nuts in rotation
diagonally, taking care to tighten them
equally.
Please see Preparing for Road Page 11 for

CHECK THE WHEEL NUTS BEFORE
STARTING EVERY JOURNEY
IMPORTANT NOTICE:
The caravan is manufactured for towing
behind road cars and the 4 x 4 “off road” type
of passenger car derivative. THE CARAVAN
IS NOT SUITABLE FOR TOWING BEHIND
COMMERCIAL VEHICLES.
