For common scooters, many manufacturers recommend using 80W-90 gear oil. Here is relevant information about 75w90 gear oil: Classification of gear oil: 75w90 gear oil is one specification of gear oil. Ordinary vehicle gear oils are divided into three viscosity grades: 80W/90, 85W/90, and 90. Medium-duty vehicle gear oils have five viscosity grades: 75W, 80W/90, 85W/90, 90, and 85W/40. Heavy-duty vehicle gear oils also have five viscosity grades: 75W, 80W/90, 85W/90, 90, and 85W/40. Gear oils can be divided into two categories: automotive gear oil and industrial gear oil. Applications of gear oil: Automotive gear oil is used to lubricate various manual transmissions and gear drive shafts in vehicles, while industrial gear oil is used to lubricate gear devices in industries such as metallurgy, coal mining, cement, and chemical processing.

How long can the in-car recording of a dash cam be saved?

The duration for which the in-car recording of a dash cam can be saved is not fixed. As long as the video footage is not deleted or overwritten, the recording can be retained indefinitely. The length of time the recorded footage remains in the dash cam depends on several factors: the size of the memory card supported by the dash cam, the actual size of the memory card in use, and the resolution of the recorded footage. A dash cam is an instrument that records images, sounds, and other relevant information during vehicle operation. After installation, it can capture the entire driving process in video and audio, providing evidence in case of traffic accidents. It can also be used at home as a DV to record life's joyful moments or serve as a home surveillance device.

What are the causes of engine cylinder liner sinking?

Engine cylinder liner sinking is caused by excessive fuel injection during driving, leading to severe engine vibration and resulting damage. Introduction to engines: An engine is a machine capable of converting other forms of energy into mechanical energy, including internal combustion engines (reciprocating piston engines), external combustion engines (Stirling engines, steam engines, etc.), jet engines, electric motors, etc. For example, internal combustion engines typically convert chemical energy into mechanical energy. The term engine can refer to both the power-generating device and the entire machine including the power unit (e.g., gasoline engines, aircraft engines). History of engines: The engine was first invented in the UK, so the concept of the engine originates from English, with its original meaning referring to "a mechanical device that generates power."

What brand is fullrun tire?

fullrun is Fulun tire, Qingdao Fulun Tire Co., Ltd. is a company integrating tire R&D, production, and domestic and international trade. Tires are circular elastic rubber products assembled on various vehicles or machinery for ground rolling, usually mounted on metal rims. They can support the vehicle body, cushion external impacts, achieve contact with the road surface, and ensure the driving performance of the vehicle. Tires are one of the important components of a car, and their main functions are: 1. To prevent severe vibration and early damage to automobile parts, adapt to the high-speed performance of the vehicle and reduce driving noise, ensuring driving stability and comfort; 2. To bear the load of the car and transmit forces and torques in other directions.

Can Water Be Added to a Car's Radiator?

Water can be added to a car's radiator, but prolonged use of water may corrode the radiator. Introduction to Car Radiator: A car radiator generally refers to the car's cooling radiator, which is part of the car's cooling system. The radiator in the engine's water cooling system consists of three parts: the inlet chamber, outlet chamber, main plate, and radiator core. Common Radiator Failures: The hoses of a car radiator may age and become prone to cracking after prolonged use, allowing water to easily enter the radiator. If a hose bursts while driving, the high-temperature water spray can form large clouds of steam escaping from under the engine hood. In such cases, immediately park in a safe location and take emergency measures to address the issue.

How Often Should Motorcycle Drum Brake Pads Be Replaced?

Motorcycle drum brake pads should be replaced every 60,000 kilometers. Factors affecting brake pad replacement: It mainly depends on the vehicle's driving conditions, the frequency and force with which the driver presses the brake pedal. Some brake pads have larger metal particles, and a brief burnt smell may occur when these metal particles are being worn down. Brake pad wear: Vehicles frequently driven in urban areas will experience faster brake pad wear compared to those mainly driven on highways. This is because city driving involves frequent stops and starts, resulting in more brake usage. Heavier vehicles also have greater brake pad wear. When decelerating at the same speed, heavier vehicles have greater inertia, requiring more friction force from the brake pads, leading to increased wear.

Why do some trucks not have synchronizers?

Some trucks do not have synchronizers due to cost considerations. Here is an introduction to synchronizers: 1. Classification and structure: Synchronizers come in various forms such as constant pressure type, inertial type, and self-energizing type. Currently, the inertial type synchronizer is widely used. It mainly consists of a coupling sleeve and a synchronizer lock ring, and its characteristic is achieving synchronization through friction. 2. Constant pressure type synchronizer: A spline hub 1 is installed between the first shaft gear 2 and the gear 4, which is loosely fitted on the second shaft 5. The spline hub is slidingly connected to the second shaft and the coupling sleeve 3 through its internal and external splines. By moving the coupling sleeve to the left or right, its internal spline gear ring can engage with the gear ring of gear 2 or gear 4, thereby engaging the direct drive or second gear.
