在冬季,由于变速箱内齿轮油的浓度和粘度随气温的降低而增大,而有的驾驶员在起动时,将主变速杆放在空档位置,副变速杆挂在档位上,未将离合器踏板踏下,就对发动机进行预热起动,这样操作使起动阻力增加,引起起动困难。下面谈谈丰收-35型拖拉机冬季起动时(环境温度低于8℃)的正确操作方法: ①将60°～80℃的热水加入冷却系,可反复多次。②将加热到80℃左右的机油加入曲轴箱内。
In winter, due to gearbox gear oil concentration and viscosity increases with decreasing temperature, and some drivers at startup, the main gear lever in neutral position, the auxiliary gear lever hanging on the gear, not When the clutch pedal is depressed, the engine is preheated and started. This operation increases the starting resistance and causes difficulty in starting. Here to talk about the harvest -35 tractor during winter start (ambient temperature below 8 ℃) the correct method of operation: ① 60 ° ~ 80 ℃ hot water into the cooling system can be repeated several times. ② will be heated to about 80 ℃ oil into the crankcase.
