Bulldozers, with their powerful earthmoving capabilities and adaptability to complex terrain, have become indispensable key equipment in fields such as construction, mining, and land reclamation. As the core guarantee for maintaining efficient equipment operation, the quality, compatibility, and maintenance of bulldozer spare parts directly impact their operating efficiency, equipment lifespan, and construction safety. This series will systematically review relevant information about bulldozer spare parts, providing comprehensive guidance from identifying types to purchasing tips and maintenance methods.

In the previous article, we analyzed the key points for purchasing bulldozer spare parts. In this article, we will continue to analyze how to care and maintain bulldozer spare parts.

(I) Regular Inspection System

Daily Inspection Items: Operators should conduct routine inspections before daily operations to check for proper track tension, loose bolts, hydraulic line leaks, and normal fuel and lubricant levels. Any abnormalities should be addressed promptly to prevent minor problems from escalating.

Regular in-depth inspections: Perform a comprehensive inspection every specified operating hours (e.g., every 500 or 1000 hours) as specified in the equipment manual. Key components, such as the engine, transmission, and hydraulic system, should undergo specialized inspections, including measuring gear wear, checking bearing clearance, and testing hydraulic component performance. Parts that are aged or worn excessively should be replaced promptly.

(II) Standard Operation and Use

Strictly follow operating procedures: Operators should undergo professional training and be familiar with the bulldozer’s performance and operating requirements. Avoid operating inappropriately, such as overloading, sudden acceleration, or sudden braking, to reduce abnormal wear of spare parts. For example, during bulldozing operations, operate the joystick smoothly to prevent the blade from suddenly striking hard objects, potentially damaging the shovel arm or cylinder.

Reasonably plan operating loads: Arrange operations based on the bulldozer’s rated power and load capacity, and avoid prolonged overloading. Overloading can cause excessive stress on components such as the transmission and travel systems, accelerating wear and aging and shortening their service life.

(III) Key Points for Scientific Maintenance

Lubrication System Maintenance: Regularly replace engine oil, transmission oil, hydraulic oil, and other components, using oils that meet specifications. Grease all lubrication points, such as track pins, track roller bearings, and drive shaft universal joints, according to the lubrication chart to ensure adequate lubrication of moving parts and reduce friction and wear.

Hydraulic System Maintenance: Regularly clean the hydraulic oil tank and filter, and replace the hydraulic oil filter element to prevent oil contamination. Check the seals of hydraulic line joints and promptly replace any aging seals to prevent hydraulic oil leaks. Maintain the hydraulic oil temperature within a normal range to prevent high temperatures from causing oil deterioration and parts aging.

Rust Prevention of Metal Parts: Regularly remove rust and paint exposed metal parts of the bulldozer, such as the blade and track shoes, to prevent rust damage. When the equipment is parked for an extended period, lower the working mechanism to the ground, apply anti-rust oil, and cover with a rainproof sheet to protect the parts from the elements.

Electrical System Maintenance: Keep electrical components clean and dry. Regularly check wiring connections for tightness and signs of looseness or oxidation. Clean oxides from battery electrodes, replenish electrolyte, and ensure proper functioning of the starting and charging systems.

The quality, selection, and maintenance of bulldozer spare parts are directly related to the equipment’s operating efficiency, service life, and construction safety. When selecting spare parts, adhere to the principle of compatibility, strictly control quality, and comprehensively evaluate cost-effectiveness. During daily use, establish a comprehensive inspection system, standardize operating procedures, and perform scientific maintenance. Only in this way can the bulldozer’s performance advantages be fully utilized and the smooth progress of construction projects be ensured.
