How to Troubleshoot: Stihl Chainsaw Oil Pump Not Working

Check the Oil Level

One of the first things to do when troubleshooting a Stihl chainsaw oil pump that’s not working is to check the oil level in the reservoir. Ensure that there is enough oil in the tank for the pump to function properly. Low oil levels can lead to oil pump issues and may cause the pump to stop working altogether.

Inspect the Oil Filter

The oil filter in the chainsaw’s oil system plays a crucial role in ensuring smooth oil flow. A clogged or dirty oil filter can restrict the flow of oil
leading to oil pump problems. Inspect the oil filter for any signs of blockage or dirt accumulation. If necessary
clean or replace the oil filter to restore proper oil flow.

Examine the Oil Pump Drive Gear

it may need to be replaced to restore the oil pump’s functionality.

Check for Clogged Oil Lines

Clogged oil lines can impede the flow of oil from the reservoir to the oil pump
causing the pump to malfunction. Inspect the oil lines for any blockages or obstructions that may be hindering the oil flow. Clear any clogs or debris from the oil lines to ensure proper oil delivery to the pump.

Inspect the Oil Pump Components

Take a close look at the various components of the oil pump
including the pump body
piston
and seals. Any damage or wear to these components can affect the pump’s performance. Carefully inspect each part for signs of wear
damage
or leaks. Replace any worn or damaged components to restore the oil pump’s functionality.
