Cleaning the oil flinger.
Tools needed
- pipe wrench #10
- container to drain oil
Inside the motor of 500 oil is filtered through two components:
1 - The retina at the start of the oil suction tube,
2 - The centrifugal filter.
The 500 does not have a cartridge filter, but a centrifugal Slinger that causes the oil and heavy impurities to get stuck to the wall + the Slinger.
Then the flow continues into the crankshaft via the camshaft axis reaches the cylinder banks and the oil sensor and then continues ... ... continues to fall in the cup from the valve cover.
PROCEDURE - With a key #10 removed the 6 nuts that hold the lid of the centrifuge (see photo), put a container under the lid to catch the oil trapped in the Slinger, under this cover you will find the real Slinger. Dis-assembly of the centrifugal device involves the extraction of the locking nut, the nut is tightened with a high torque and therefore not easy to remove.
- Check the walls of the slinger and the walls of the lid that there is no residual sludge (see photo) if there is scrape the layer of loose dirt with a screwdriver and clean with a rag soaked in oil. Be careful not to leave any strands of cloth in the slinger, it could block the flow of oil causing engine damage.
- Once cleaned reassemble the cap of the slinger putting a new gasket.
The correct mounting position of the cap is manditory because it carries on its surface a references to the ignition timing (TDC) (see photo). [More]
