Step-by-Step Guide to Changing Engine Oil and Filter

Step 1: Prepare the Excavator

  • Lower the Bucket: Bring the bucket down to the ground to stabilize the machine.
  • Turn Off the Engine: Shut down the engine, remove the key, and store it in a safe place. Allow the machine to cool down to ambient temperature before proceeding. This ensures safety and prevents burns from hot oil.

Step 2: Locate the Oil Drain Bolt, Oil Fill Port, and Oil Filter

  • Remove Rear Panel and Lift Seat.
Take off the rear cover of the small excavator using a 12mm wrench and tilt the seat forward. This will expose the oil drain bolt, oil fill port, oil dipstick, and oil filter.

Remove the Oil Drain Bolt. Place an oil pan underneath, then use a 12mm wrench to remove the oil drain bolt. Let the old oil flow out completely.

Be patient—this might take a few minutes. Once drained, screw the drain bolt back tightly to prevent any leaks.

Step 4: Remove and Replace the Oil Filter

  • Remove the Old Filter: Use a filter wrench to turn the old filter counterclockwise and remove it. Clean the mounting surface to ensure a proper seal for the new filter.
  • Prepare the New Filter: Apply a thin layer of clean engine oil to the seal on the new filter. This helps create a better seal and makes removal easier during the next change.

  • Install the New Filter: Screw the new filter on by hand. Once the seal makes contact with the mounting surface, use the filter wrench to tighten it an additional 3/4 turn.

Don’t overtighten—this could damage the filter or cause leaks.

Step 5: Refill the Engine Oil

Add New Engine Oil: Place a funnel in the oil fill port and pour in the new 5W-30 synthetic oil. Be careful not to overfill. Check the dipstick and ensure the oil level is between the upper and lower marks. The oil should not exceed the upper mark on the dipstick.

Secure the Oil Fill Cap: Once filled, tightly screw the oil fill cap back on.

Check the dipstick and ensure the oil level is between the upper and lower marks.

 

Step 6: Clean Up and Test the Machine

  • Clean Up: Wipe off any spilled oil around the engine and oil filter area.
  • Reinstall Cover and Seat: Put the rear cover and seat back in place.
  • Start the Engine: Turn on the engine and let it idle for a few minutes. Check for any leaks around the oil filter and drain bolt area.
