You are performing a pre-operational inspection on an excavator that has been operating on a muddy job site for several days. You find that the final drive covers are heavily caked with dried mud, making it difficult to even see the bolts.

Question: You are performing a pre-operational inspection on an excavator that has been operating on a muddy job site for several days. You find that the final drive covers are heavily caked with dried mud, making it difficult to even see the bolts.

Answer options: ✅ Clean off the mud from the final drives to inspect for leaks or damage.

• Assume the final drives are protected by the mud and proceed with operation.
• Spray the final drives with a degreaser and rinse them only after the shift.
• Check only the visible areas of the undercarriage and ignore the caked mud.

Correct answer: Clean off the mud from the final drives to inspect for leaks or damage.

Explanation: Heavy accumulation of mud on final drives can conceal leaks, damage, and prevent proper cooling. Cleaning them during the pre-operational check is essential to allow for a thorough inspection of these critical components, ensuring optimal performance and detecting any issues before operation. Ignoring it would mean operating without fully knowing the condition of vital parts.
