Most Common Reasons Why Chainsaw Oil Pump Not Working

1. Clogged Oil Pump

The most common reason for a chainsaw oil pump not working is a clogged oil pump. This can be caused by dirt, sawdust, or other debris getting into the pump and preventing the oil from flowing properly. To fix this, you will need to clean the oil pump.

2. Blocked Oil Passages

Another common cause of a chainsaw oil pump not working is blocked oil passages. This can be caused by dirt, sawdust, or other debris getting into the oil passages and preventing the oil from flowing to the chain. To fix this, you will need to clean the oil passages.

3. Faulty Oil Pump

In some cases, the oil pump itself may be faulty. This can be caused by a manufacturing defect or by damage to the pump. If the oil pump is faulty, it will need to be replaced.

4. Low Oil Level

If the oil level in the chainsaw is too low, the oil pump will not be able to pump enough oil to the chain. This can cause the chain to become dry and overheat, which can damage the chain and the chainsaw. To fix this, you will need to add more oil to the chainsaw.

5. Incorrect Oil Type

Using the wrong type of oil in your chainsaw can also cause the oil pump to not work properly. Some chainsaws require special oil, so it is important to use the correct type of oil for your chainsaw.

6. Misaligned Oil Pump

In some cases, the oil pump may be misaligned. This can prevent the oil from flowing properly to the chain. To fix this, you will need to realign the oil pump.

How to Troubleshoot: Chainsaw Oil Pump Not Working

Symptoms of a Chainsaw Oil Pump Not Working

There are a few telltale signs that your chainsaw oil pump may not be working properly. These include:

The chain is not being lubricated properly, which can lead to overheating and damage to the chain and bar.
The oil level in the reservoir is low, even though you have been adding oil regularly.
The oil pump is making a strange noise when it is running.
The oil pump is not pumping oil at all.

Troubleshooting a Chainsaw Oil Pump

If you suspect that your chainsaw oil pump is not working properly, you can troubleshoot the problem by following these steps:

1. Check the oil level in the reservoir. If the oil level is low, add oil to the reservoir until it reaches the full mark.
2. Inspect the oil pump for damage. Look for cracks, leaks, or other damage to the oil pump. If you find any damage, you will need to replace the oil pump.
3. Check the oil pump’s O-ring. The O-ring is a small rubber gasket that seals the oil pump to the engine. If the O-ring is damaged or worn out, it can cause the oil pump to leak oil. To check the O-ring, remove the oil pump from the engine and inspect the O-ring for damage. If the O-ring is damaged, you will need to replace it.
4. Check the oil pump’s drive gear. The drive gear is a small gear that drives the oil pump. If the drive gear is damaged or worn out, it can cause the oil pump to not work properly. To check the drive gear, remove the oil pump from the engine and inspect the drive gear for damage. If the drive gear is damaged, you will need to replace it.
5. Check the oil pump’s linkage. The linkage is a small rod that connects the oil pump to the engine. If the linkage is damaged or misaligned, it can cause the oil pump to not work properly. To check the linkage, remove the oil pump from the engine and inspect the linkage for damage. If the linkage is damaged, you will need to replace it.

Replacing a Chainsaw Oil Pump

If you determine that the oil pump needs to be replaced, you can follow these steps to replace it:

1. Remove the old oil pump. To remove the old oil pump, you will need to first remove the chain guard and bar from the chainsaw. Once the chain guard and bar are removed, you will need to locate the oil pump. The oil pump is usually located on the side of the engine. Once you have located the oil pump, you will need to disconnect the oil pump’s linkage from the engine. You will also need to disconnect the oil pump’s hose from the engine. Once the oil pump is disconnected, you can remove it from the engine.
2. Install the new oil pump. To install the new oil pump, you will need to reverse the steps you took to remove the old oil pump. First, you will need to connect the oil pump’s hose to the engine. Then, you will need to connect the oil pump’s linkage to the engine. Once the oil pump is connected, you can install the chain guard and bar.

Preventing Chainsaw Oil Pump Problems

You can help prevent chainsaw oil pump problems by following these tips:

Keep the oil level in the reservoir full. A low oil level can cause the oil pump to work harder, which can lead to damage to the oil pump.
Inspect the oil pump regularly for damage. Look for cracks, leaks, or other damage to the oil pump. If you find any damage, you will need to replace the oil pump.
Replace the oil pump’s O-ring regularly. The O-ring is a small rubber gasket that seals the oil pump to the engine. If the O-ring is damaged or worn out, it can cause the oil pump to leak oil.
Replace the oil pump’s drive gear regularly. The drive gear is a small gear that drives the oil pump. If the drive gear is damaged or worn out, it can cause the oil pump to not work properly.
Keep the oil pump’s linkage lubricated. The linkage is a small rod that connects the oil pump to the engine. If the linkage is not lubricated properly, it can cause the oil pump to not work properly.
