In addition to this, we can also check micro-psychological or public numbers: vehicle accident risk records, risk insurance, business risk insurance, vehicle status, mortgage status, kilometres, vehicle plates, frame numbers, number of vehicles, etc
Iii. Access to permits and maintenance manuals
The permit and maintenance manual, which is an important document and information for vehicles, usually records vehicle protection. By looking at these two documents, you can find information about the duration of maintenance of the vehicle, the maintenance mileage, etc. It should be noted, however, that this information may not be exhaustive enough to give you a full picture of the protection status of the vehicle。
Lubrication system maintenance
(b) retrofit tank oil inspection and replacement (manual/automated block): the transformer tank oil is capable of lubricating parts such as gears, bearings, etc. In the gear tank, reducing wear, while also transmitting power and heat dispersion. Periodicity: manual transformer tank oils are usually replaced every 60,000 - 80,000 km; automatic transformer tank oil replacement cycles are relatively complex and require different types of inspections, usually every 40,000 - 60,000 km, every 80,000 - 100,000 km, and parts of the vehicle models may be refuelled to allow for more thorough replacement of transformer tank oil。
Brake oil inspection and replacement: brake oil transmits pressure in the brake system so that the force of the brake pedal can be passed to brake card clamps or brake drums to perform brake functions. Periodic: brake oils shall normally be replaced with water content and boiling points, if they contain more than 3 per cent of water or if they are too low. As brake oil is water-sorting, the amount of water that is present after long periods of use increases, leading to lower boiling points and affecting brake performance。
Shift to boost oil inspection and replacement (the hydraulic booster type): the shift to boost oil can help the hydraulic booster shift system and make the wheel easier for the driver. Cycle: the fluids and oils that are converted to boosters are usually checked every 2 years or 40,000 - 60,000 km and replaced every 40,000 - 60,000 km. If, however, a shift-aided oil is found to be spoiled, alienated or liquid-level abnormal, it should be replaced in a timely manner。
Iv. Subway system maintenance
The brake system checks the brake blades: the brake blade is a component of the brake system that has a friction effect in direct contact with the brake plate and the degree of wear directly affects the brake performance. In general, every 10,000 to 20,000 kilometres of brake blade thickness is checked and when the brake blade thickness is worn close to the limit value (usually around 3 mm), the brake blade shall be replaced. Brake plate checks: brake plates may also be worn as they are used, with the risk of surface imbalance. In general, brake plates should be replaced for every 20,000 - 30,000 km, such as excessive wear and tear on the brake plates (less than the limit) or serious scratches on the surface. Brake pipeline inspection: check whether the brake pipeline is ageing, leaking, breaking, etc., to ensure that the brake pipeline works properly and to prevent brake failure。
Tyre checks and the maintenance of tyre pneumatics: excessive or low tyre pneumatic pressure affects the conduct, comfort and safety of vehicles and accelerates tyre wear. Tyre air pressure should be checked once a month and adjusted to the standard air pressure specified in the vehicle usage manual. Tyre wear and tear: the tyre should be replaced when the depth of the tyre wreath is less than 1. 6 mm. At the same time, examination of whether tyres have abrasions, drums, cracks, etc., should be addressed in a timely manner if abnormal. Tyre exchange: in order to achieve even wear and tear of tyres and to extend the useful life of tyres, it is generally done every 10,000 - 20,000 km. Common swaps are cross-places and loops。
Hanging systems to check shock-reducing devices: the shock-reducing devices can buffer the vibrations during the vehicle's journey and improve the comfort of the ride. Check if there are oil spills, noises, etc., and replace them in a timely manner if there are problems. Spring-leash inspection: check if the spring is deformed, fractured, etc. To ensure that the suspension system works properly。
Electrical system maintenance
Vases check vials for voltage: the voltage of the vials is checked on a universal watch, and the normal voltage should be between 12v - 14v. If the voltage is too low, it may affect vehicle start-up and normal use of electrical equipment. Appearance inspection of electric cylinders: check for drum packs, leaks, etc., and replace bottles in a timely manner if abnormal. Valve life assessment: the life of the cylinder is typically 2 - 3 years, and if the bottle is used for longer periods, even if the appearance and voltage are normal, the replacement should be considered to avoid problems such as start-up difficulties at critical times。
The light system inspects the external light: it includes headlights (distant light, near light), turning light, brake light, mist light, reverse light, etc., checking whether the light is bright, normal blinking and, in the event of damage to or failure to light, the light bulb shall be replaced in a timely manner. Internal light check: checks if reading lights, dashboard lights, etc. Are working。
Rain-scraper inspection and replacement of rain-scraps inspection: check whether the rain-scrap is ageing, hardening, cracking, etc. And whether the rain-scrap and windshields are well matched. If the scrape is not clean or resounding, it should be replaced in a timely manner. Rain-scraper inspection: check if the rain-scraper is working properly, if the rain-scratching speed is even, and if unusual, if the rain-scraper and the associated circuits are to be checked。
