9.Remove the pump suction line from the tank outlet cover, remove the three cap screws that secure the cover, then carefully remove the cover.

10.Use mineral spirits and rags to clean the inside of the tank. Make sure to soak up any excess mineral spirits with dry rags so that it does not stay in the tank and contaminate the oil.

Tip: Consider placing one or two magnets at the bottom of the tank to collect any fine metal particles. This will make cleaning easier the next time around and reduce the amount of metal particles that may end up in the oil.

11.Re-install the tank outlet cover with a new gasket or silicone sealant.

12.Place the funnel in the fill spout and add the new oil.

13.Re-install the tank fill cap and end gear and tank access covers, then test the oil pump operation.
