Chainsaws are powerful tools that come in handy for a variety of tasks. However, if you notice oil leaking from the chainsaw’s bar, it can be a sign of trouble. Leaking bar oil can be a safety hazard and could lead to damage to your chainsaw if left unchecked. In this article, we will discuss the most common reasons why chainsaws leak bar oil and what you can do to fix the problem.
Causes of Chainsaw Bar Oil Leaks
Poor ventilation is one of the most common reasons why chainsaws leak bar oil. When your chainsaw is running, the oil pump works to lubricate the chain, and the excess oil is returned to the oil tank via the oil return hose. If the ventilation system is clogged or damaged, the excess oil will have nowhere to go, causing it to leak. To fix this issue, you need to clean or replace the ventilation system, depending on the severity of the blockage.
Faulty Oil Pump
A faulty oil pump is another reason why chainsaws leak bar oil. The oil pump is responsible for delivering the right amount of oil to the chain, and when it is not working correctly, it can lead to excessive oil leakage. If you suspect that the oil pump is faulty, you should seek professional help to get it repaired or replaced.
Worn Out or Damaged Bar
A worn-out or damaged bar can also cause your chainsaw to leak bar oil. When the bar gets damaged, it can create gaps between the bar and the oil tank, causing oil to leak through the gaps. To fix this issue, you need to replace the damaged or worn-out bar with a new one.
Clogged Oil Filter
An oil filter is responsible for filtering the oil before it reaches the chain. If the oil filter is clogged, it can cause the oil to back up and leak through the bar. To fix this issue, you need to clean or replace the oil filter.
Improper Chain Tension
If the chainsaw chain is too tight, it can put extra pressure on the bearings, causing them to leak. To fix this issue, you need to adjust the chain tension to the manufacturer’s recommended specifications.
How to Fix a Leaking Chainsaw
If your chainsaw is leaking bar oil, there are a few things you can do to fix the problem. These include:
Replacing the Bar Gaskets: If the gaskets are worn, you can replace them to stop the leak.
Replacing the Seals: If the seals are damaged, you can replace them to prevent more oil from leaking out.
Cleaning the Oil Reservoir: If the oil reservoir is clogged, you can clean it to prevent more oil from leaking out.
Chainsaw bar oil leaks can be caused by worn gaskets, damaged seals, and clogged oil reservoirs. If your chainsaw is leaking bar oil, there are a few signs to look out for, such as oil dripping from the bar, oil residue on the chainsaw, and excessive smoke. To fix a leaking chainsaw, you can replace the bar gaskets, replace the seals, and clean the oil reservoir.
