[MikePhua]

Introduction
The Komatsu PC45-1 is a compact hydraulic excavator renowned for its agility and efficiency in various construction tasks. To ensure optimal performance and longevity, it's crucial to adhere to the manufacturer's lubrication specifications, particularly concerning the final drive system.
Final Drive Lubrication Requirements
For the Komatsu PC45-1, the final drive system requires a specific type of lubricant to function efficiently:

• Lubricant Type: SAE 30W oil
  
• Specification: Komatsu KES 07.861
  
• Alternative: SAE 80W-90 gear oil
  

It's essential to use lubricants that meet the Komatsu KES 07.861 specification to maintain the integrity of the final drive components. Using oils that do not meet this specification can lead to increased wear and potential failure of the final drive system.
Final Drive Oil Capacity
The oil capacity for each final drive on the Komatsu PC45-1 is approximately 1.1 liters. Therefore, for the entire machine, the total final drive oil capacity is around 2.2 liters. Regular checks and maintenance are recommended to ensure the oil level remains within the optimal range.
Maintenance Recommendations
To prolong the life of the final drive system and ensure the excavator operates at peak performance:

• Regular Oil Checks: Periodically check the oil level and condition.
  
• Oil Replacement: Replace the oil at intervals recommended by the manufacturer or based on operating conditions.
  
• Seal Inspections: Inspect seals for any signs of wear or leakage to prevent contamination and loss of lubrication.
  

Conclusion
Adhering to the specified lubrication requirements for the Komatsu PC45-1 final drive system is vital for maintaining the excavator's performance and longevity. Regular maintenance and using the correct lubricants will help in achieving optimal operational efficiency and reducing the risk of costly repairs.
