How Many Kilometers Should BPW Axles Be Serviced?
2 Answers
Introduction to how many kilometers BPW axles should be serviced is as follows: 1. Primary maintenance (approximately 5,000 kilometers): Maintenance operations centered on tightening and lubrication for motor vehicles that have traveled a certain distance. Includes inspecting and tightening bolts and nuts on exposed parts of the vehicle; adding lubricant to specified lubrication points; checking the oil level in various assemblies and adding lubricating oil; cleaning air filters, etc. The purpose is to maintain the vehicle's good technical condition and ensure normal operation. 2. Secondary maintenance (approximately 10,000 kilometers): Maintenance operations centered on inspection and adjustment for motor vehicles that have traveled a certain distance. The scope of maintenance, in addition to the primary maintenance tasks, includes inspecting and adjusting the operation of the engine and electrical equipment, dismantling and cleaning the oil pan and oil filter, inspecting and adjusting the steering and braking mechanisms, dismantling and cleaning the front and rear wheel hub bearings. Adding lubricating oil, dismantling and inspecting tires, and performing tire rotation, etc. The purpose is to maintain the good working performance of various components, mechanisms, and assemblies of the vehicle and ensure normal operation between two secondary maintenance intervals. 3. Tertiary maintenance (approximately 20,000 kilometers): Maintenance operations centered on disassembling, cleaning, inspecting, adjusting, and eliminating hidden dangers in assemblies for motor vehicles. The scope of maintenance: In addition to performing all tasks of primary and secondary maintenance, it includes dismantling and inspecting the engine to remove carbon deposits, gum deposits, and cooling system contaminants; dismantling, cleaning, inspecting, adjusting, and eliminating hidden dangers in chassis assemblies as needed; inspecting the frame and body or performing rust removal and touch-up painting. The purpose is to consolidate the normal performance of various assemblies and components and ensure normal operation.
I've been driving heavy trucks for over 20 years and have used many BPW axles. The usual maintenance interval is every 50,000 kilometers. But this isn't absolute—when I frequently run long-distance heavy loads, especially on poor road conditions like mountainous routes or with full cargo, I have to advance the maintenance to 40,000 kilometers. The main maintenance tasks include changing the gear oil, checking if the oil seals are leaking, and lubricating the joint bearings. Once, I neglected timely maintenance, and the axle started squeaking, costing me several thousand in repairs—a big loss. Before driving, I also make it a habit to quickly check the oil level to ensure safety. Remember, the vehicle manual may have specific recommendations, especially for new or special models—follow them. Regular maintenance can extend the axle's lifespan by over ten years, saving both hassle and money.
