Product Information

If you detect a leak in your air braking system, leave the vehicle parked and find someone to fix it. Don’t drive it until it’s fixed otherwise you could end up with no brakes. Gearbox

Options for 1-2 working day delivery and next day timed services available on most items Zone B Surcharge AreasIf you see this warning light then you have a problem with your oil pressure. Continuing to drive with this light on could cause your engine to seize. If there’s not enough oil pressure the engine components won’t be lubricated. They will overheat and eventually will seize.

If you notice a lump or bulge, a deep cut more than 25mm (1 inch) long, or exposed ply or cords, then the tyre is illegal to use on the road. You can see in this following video how much force a tyre on a heavy vehicle can explode with in a blowout. Consistent high speeds for long distances on motorways can cause your tyres to overheat and disintegrate. This is more likely to be the case if they are under-inflated because this creates more rolling resistance that is dissipated in the form of heat. On light vehicles, the most common coupling is an A-frame drawbar coupled to a 1 7/8 inch or 50mm tow ball. These drawbars transmit around 10% of the gross trailer weight through the coupling. If you have been issued with protective clothing by your company for use while driving, it is your responsibility to wear it.It is also a requirement for the manufacturer’s date code to be legible on all tyres fitted to LGV tractor units and trailers over 3.5 tonnes. When you start the engine the ignition light should go out. If it doesn’t, you have an electrical fault.

If you are driving a vehicle with a two-speed axle, this doubles the number of gears. An electrical switch actuates a mechanism in the rear axle which doubles the choice of gear ratios, which can significantly improve the performance of a heavily laden vehicle. Diesel expands in the heat. If your fuel tank is filled to the brim and it’s a hot day, expansion of the fuel will cause it to spill on the road which is very dangerous, especially for motorcyclists. Don’t fill your fuel tank to the brim. Aggressive reversing can break or bend the funnel which directs the towing eye into the jaw. In this case, the drawbar height was too low and the approach speed too fast. The funnel couldn’t direct the drawbar into the jaw, instead breaking through the funnel.

If you are driving a vehicle fitted with a turbocharger these can heat up to 600 degrees Celsius. When you stop, allow your engine to idle a short time (around a minute) to help the turbo cool. Some vehicles will have a turbo timer fitted to allow this to happen without you waiting with the vehicle. Oil Damage can be caused by clumsy or aggressive coupling techniques, manoeuvring outside of the range of the coupling, and poor maintenance and care of the parts. Cables and air lines The direction of haulage may be push or pull, though pushing tends to be for a pair of ballast tractors working together, one pulling and the other pushing an exceptional load on a specialist trailer. The most common drawbar configuration for heavy vehicles is an A-frame drawbar at the front of a full trailer that connects to a tow coupling on a hauling vehicle [1] Overfilling your engine with oil could cause a loss of power. This is because moving engine parts could hit the oil. This can even damage the engine. Overfilling with oil can also cause excess pressure which can damage oil seals and cause leaks. The fifth wheel coupling is used to connect a tractor unit to a trailer. It allows articulation between the tractor and trailer.
