How many milliliters of gear oil should be added to the rear axle of an electric tricycle?

Electric tricycle rear axles require between 100 to 200 milliliters of gear oil. Here are the specific details: Maintenance tips: When changing the gear oil of an electric tricycle in winter, it is best to choose the oil used for motorcycles, as this can better reduce the vehicle's resistance during winter driving. However, if the electric tricycle has a central motor, be careful not to add more than approximately 150 milliliters of oil, as overfilling may cause leakage from the brake area. The role of gear oil: It prevents wear, scratches, or sintering on the gear surfaces inside the electric tricycle. Gear oil mainly refers to the lubricating oil used in the transmission and on the central axle. The usage requirements, internal composition, and performance of this oil vary.
I've been repairing electric tricycles for over a decade. The rear axle gear oil quantity depends on the specific model. Generally, models with a 500kg load capacity require about 200-250ml, and common brands like Jinpeng and Zongshen are roughly the same. For heavier agricultural models, it might need around 300ml. The safest method is to locate the inspection hole on the side of the rear axle and fill until the lubricant just starts to overflow. Remember to use GL-5 grade gear oil - thinner oils can't handle the heavy load of tricycles. Last week when repairing a villager's vehicle, I found overfilling caused oil seal leakage, which actually accelerates gear wear.
