4, the choice of gear oil Note (1) must not be used in place of hypoid gear oil conventional gear oils. As 18 # hypoid gear oil can not be used for transmission and rear axle at high speeds and heavy duty vehicles; (2) Do not mistake the lubricating properties of high viscosity gear oil well. Car class fuel economy also select the gear oil viscosity is related to the use of high-grade gear oil viscosity too, will make a significant increase in fuel consumption, especially in a greater impact on the high-speed cars, should be as small and medium viscosity using multistage gear oils, such as 75W / 90,80W / 90 to meet vehicle transmission and gear lubrication device, also play better fuel efficiency. Especially in the northern winter to choose suitable for the local environment of low temperature fluidity and better gear oil (viscosity here refers to the selection), as well as a new car or overhaul run-run-in period should not be too big of a viscosity of choice (such as the use 85W -90,80W-90,75W-90 and other flow better gear oil); (3) the amount of fuel should be appropriate. Oil should be appropriate, not too much nor too little. Too much not only increases the churning resistance and fuel consumption, but also it is possible to gear oil after the axle shaft seal (sealing poor) to leak into the wheel bearings, causing bearing grease dilution, the brake drum brake failure; too little makes Gear poor lubrication, temperature, acceleration gear wear. Gear oil should generally be applied to the gearbox filler flush with the lower edge, and should always check the gear oil tank leaks, and keep all seals, gaskets intact. (4) timely oil changes. Shall be specified by the manufacturer of the vehicle oil change indicator replaced with new oil is the best oil change, such as vehicles often in harsh operating conditions, to shorten the oil change. Oil change, the old oil should be hot release, and gear and gear box before adding new oil to clean later. When refueling, should prevent moisture and contamination and mixed with other substances. (5) gear oil use taboo. In use, the non-gear oil added to the diluted diesel, things do not add a thickener or other anti-wear agents and the like, do not due to start of the winter and baking bridge, transmissions, gear oil in order to avoid a serious deterioration, appear gums or coke and so on. If this occurs, it should be replaced with low-temperature fluidity low viscosity better multi-stage gear oil. (6) the maintenance of the gearbox and rear axle After gasoline or diesel components must be cleaned gasoline or diesel, especially in the case of fuel left, if the gear oil mixed with fuel oil, gear oil after a period of time will change color brown and red. Mixed with excessive amount of oil will cause the gear change. (7) gear oil is not easy and should not be stored for long term storage at high temperatures. Vehicle gear oil Storage: should be stored at room temperature, a cool, dry place. Not at higher temperatures (eg above 40 ℃) long-term storage. Because high temperatures will accelerate decomposition extreme pressure additives or promoting the reaction between, but also affect the foam of gear oils. Furthermore, it should prevent the oil in the water, to prevent hydrolysis extreme pressure agents generate water-soluble acidic substance. (8) Note that if you use the vehicle during the bridge and the gearbox vent poor ventilation after regular checks, gearbox overheating and other irregularities, such as the emergence of irregularities to the pits in time to conduct a comprehensive inspection.
