Chainsaws are powerful tools that require regular maintenance to ensure optimal performance and longevity. The oil pump is a vital component in chainsaws, responsible for lubricating the bar and chain. Over time, the oil pump may need disassembling to clean or replace certain parts. In this guide, we will walk you through the step-by-step process of disassembling a chainsaw oil pump.

What You Will Need

  • A screwdriver set
  • A clean cloth or paper towels
  • Replacement parts (if necessary)

Step 1: Preparation

Before starting any maintenance task, it’s crucial to ensure your safety. Make sure the chainsaw is turned off, the spark plug is disconnected, and the chain brake is engaged. Additionally, have a clean and clear work area to avoid any mishaps or lost parts.

Step 2: Accessing the Oil Pump

Locate the oil pump cover on the chainsaw. Depending on the model, it can be found on the side or bottom of the saw. Use the appropriate screwdriver to remove the screws securing the cover in place. Once the screws are removed, gently lift off the oil pump cover.

Step 3: Removing the Oil Pump Components

Inside the oil pump housing, you will find several components. Carefully remove the pump body, pickup hose, filter, and any additional parts present. Pay attention to the order and orientation of the parts as you remove them to ensure correct reassembly later.

Step 4: Cleaning and Inspecting the Parts

Once you have disassembled the oil pump, it’s important to clean each part thoroughly. Use a clean cloth or paper towels to wipe away any dirt, debris, or residue from the components. Inspect each part for any signs of wear, damage, or blockages. If you notice any issues, this might be a great opportunity to replace those parts to maintain the chainsaw’s efficiency.

Step 5: Reassembling the Oil Pump

After cleaning and inspecting the parts, it’s time to reassemble the oil pump. Start by returning the filter and pickup hose to their original position. Then carefully insert the pump body into the housing, making sure it fits snugly. Double-check if all the components are properly aligned and seated.

Step 6: Reattaching the Oil Pump Cover

Place the oil pump cover back onto the chainsaw, aligning the screw holes. Insert and tighten the screws using the appropriate screwdriver. Make sure not to over-tighten the screws to prevent damage to the cover or housing.

Step 7: Final Checks

Before you wrap up the disassembly process, it’s advisable to do one final check to ensure everything is in place and secure. Confirm that the oil pump is properly functioning by testing it after reassembling. Start the chainsaw and observe if the oil is being evenly distributed on the bar and chain.

With these simple steps, you can confidently disassemble your chainsaw oil pump for cleaning or replacement. Remember to refer to your chainsaw’s manual for specific instructions, as different models may have slight variations. Regular maintenance and proper care of your chainsaw will keep it running smoothly and extend its lifespan.
