How often should the gear oil in a tricycle rear axle be replaced?
2 Answers
Tricycle rear axle gear oil should be replaced approximately every 20,000-30,000 KM. The replacement interval may vary depending on different oil brands, but generally falls within the 20,000-30,000 km range. For new vehicles, the rear axle oil should be replaced during the 12,000 km maintenance, and then inspected every 24,000 km thereafter. If noticeable discoloration or thinning is observed, immediate replacement is required. Additional notes: Different types of hypoid gear lubricants should not be mixed, as this may cause lubricant deterioration and corrosion of the driving and driven bevel gears. Avoid introducing moisture during gear oil storage and refilling, as it can lead to oil decomposition and reduced lubrication effectiveness. When replacing deteriorated lubricant, thoroughly clean the contaminated oil from the main reducer to prevent contamination of the new oil.
I've been driving a tricycle for transport for five or six years, and changing the rear axle gear oil is quite particular. Generally speaking, it should be changed every 8,000 to 10,000 kilometers, or every six months, depending on how hard you use the vehicle. Like mine, which carries loads every day and runs on rough rural roads with heavy loads, so I change it every 8,000 kilometers. Why? If the gear oil ages or is insufficient, the gears will overheat due to friction, producing metal shavings, and a single repair can cost several hundred yuan. I see many peers being lazy and waiting until the vehicle makes strange noises before changing it—that's too late. I recommend checking the oil level regularly, and if the oil turns black or becomes thin, change it immediately. Developing this habit keeps the vehicle running smoothly and saves on repair costs.
