Care & Maintenance
Although maintenance procedures for
caravans, trailers etc. are mostly
common sense and follow the same
principals as other vehicles, the
following points may assist in covering
areas which may otherwise be overlooked.
Starting at the front of the caravan,
the following points should be
especially considered:-
• COUPLINGS
1. Override
Check that the coupling is effectively lubricated and that head and
shaft rotates freely (apply grease through nipples).
Adjusting screw and nut should not be frozen in head and should be
adjusted to stop ball from rattling (oil adjusting screw shaft by
turning coupling upside down. Lightly grease inside coupling head where
it fits over towball).
Backing stop should move freely.
OR 2. Hydraulic
Ensure free movement of all parts.
Master cylinder cap should be in good condition to prevent moisture
entering reservoir.
OR 3. Fixed
Check operation of spindle and screw nut.
NOTE: On all couplings, trigger lock on handle should be moving freely
and in good condition (oil regularly).
• HAND BRAKE
Check for rust or corrosion where base plate fixes to A frame.
Hand brake level should move freely and should travel approx. 15mm
when correctly adjusted (adjust with turnbuckle).
Check condition of brake cable and pulleys.
• SAFETY CHAIN
Should have no visible signs of rust or cracks at
fixing point and should be long enough to reach towbar chain hook and
allowing for cornering.
• JOCKEY WHEEL
Handle and wheel should turn freely (if lubrication is
needed, squirt oil under handle to travel down shaft).
Wheel should spin on axle freely.
Check clamp and clamp bolt for easy operation (apply oil to thread if
necessary).
Should be checked regularly for rust and stress fractures,
particularly outriggers and all cross member fixing points, A frame,
springs and spring hangers and stabilizer legs.
Check for signs of movement around spring hangers, shackle plates and
bushes, U-bolts and fish plates.
Check jack legs for ease of movement and ensure handle is in good
condition.
Check step for cracks, rust and ease of operation.
NOTE: Surface rust should be removed by sanding or with a wire brush and
metal surface then painted with an anti-rust paint.
• MAIN DOOR
Lubricate door lock and hinges with light oil (CRC type).
Check condition and operation of annex roller and cabin hooks.
Door lock tongue and striker plate should be regularly checked for
signs of wear.
• WHEELS, RIMS & TYRES
Check rims for buckles, cracks or other damage after each trip.
Check tyres for signs of excessive wear from under/over inflation or
wheel alignment problems.
Bearings and oil seals should be inspected and repacked regularly and
definitely before any proposed long trip.
Brake shoes should be checked for signs of uneven wear and drums for
any marks which may indicate early signs of brake deficiency.
Hydraulic lines should be checked for signs of leaking.
If electric brakes are fitted - drums should be cleared of sand/gravel
deposits to prevent excessive wear on magnets.
NOTE: Operation of all braking systems should be regularly checked for
signs of wear or fatigue in wires, clamps or connections..
• WATER TANK
Check hoses for leaks, kinks, signs of wear.
Check hoses for any mildew growth in hose.
Check clamps for tension.
Check tank straps for signs of cracking or rust.
Stoneguard if fitted should be checked for dints which may rub hole in
tank.
• EXTERIOR OF VAN
General condition of aluminium check particularly for cracks in
sheet or corrosion in roof sheets.
Check for movement above door and in lower corners of van. May
indicate chassis or frame movement. (Movement is usually indicated by
black rubbing marks).
• WINDOWS
Check glasses for cracks.
Internal and external sealing rubbers for signs of being perished or
ill fitting.
Check easy operation of windows (forcing windows will break glass).
• SHADES & PROTECTION
Pay particular attention to hinges and fixings.
Operation of stays and locks should be regularly serviced (apply light
oil - CRC etc).
• CORNER MOULDS
Sealing and around corner moulds - windows, doors etc. should be
checked for cracks or holes which may allow water to enter and rot
framing or lining sheets.
NOTE: Corner moulds should be resealed every 5 - 7 years.
• EXTERIOR
LIGHTING
Important for safety aspect that all 12V brake
indicator, tail and running lights should be operative and lenses not
faded.
Check rubber seals around all exterior light bases to prevent
intrusion of water.
Check 12V wiring and plug for any signs of breakage or insect nests in
12V plug.
• GAS FITTINGS
Check gas connections by turning bottle on and spraying fittings with
detergent and look for bubbles.
NEVER USE EXPOSED FLAME (MATCHES OR CIGARETTE LIGHTER) TO CHECK FOR
LEAKS.
Check flexible hose for fraying or kinks.
NOTE: At the time of sale of any caravan fitted with or capable of being
fitted with LP gas appliances, (i.e. gas lines fitted) a current
certificate of compliance must be supplied by the seller to the buyer.
Serious consequences can eventuate if this law is not adhered to.
• INTERIOR OF VAN
Hatch mechanisms should be lubricated and free of rust
or corrosion.
All flyscreens should be intact and still attached to rubber mould or
aluminium framing.
Check cupboards for movement which may indicate chassis problems (look
for black rubbing marks near ceiling, walls and floor where furniture
attaches).
Cupboard locks should be lubricated to avoid jamming which may strain
and break lock.
Check light glasses and affixing buttons for cracks.
Fridge and stove should be firmly fixed to surrounds - loose bolts
could result in appliance jarring loose in travel. (Grasp appliance and
attempt to move back and forth).
Check mattresses regularly for signs of moisture retention - causes
premature wear.
Any discolouration of ply lining around hatch windows or any ceiling,
floor or wall corners indicates the intrusion of water which may rot
framing or lining unless rectified quickly.
IMPORTANT NOTE: Any suspected problems with gas lines or the operation
of any gas appliance or electrical fault should be referred to a
qualified gas fitter or electrician respectively and should not be
tampered with by an unqualified person.
• STORAGE
Due to the new compound tyres available to the motor industry,
there is no real need to store caravans "on blocks" as in the days of
rubber tyres. The only advantage of "blocking" a van is to take the
pressure off the bearings, again not totally necessary.
