| Post subject: | Oil galley O-ring |
Looking for a little help. Replacing the case gasket on a 23hp briggs, it is recommended to replace the o-ring on the oil pump. I have a new o-ring for the oil pump but not sure on taking the pump apart. I assume you need to remove the plastic gear that runs the pump and o-ring is behind the pump? How does the plastic gear come off? Let me know if I am going the wrong direction on this please. PS Do you guys use a former gasket/permatex or just replace the case gasket dry? Thanks |

i dont know about a o ring on the pump, but if your talking about the oil galley o rings they go on the case surface by where your filter goes. There should be two holes there where oil passes through, the o rings go there. |

Here is the diagram from the oil pump (part number 273) Just not sure how the o-ring is installed. |

The plastic gear doesn't come off, there should be 2 bolts on the back of the crankcase cover that hold the pump on. The other poster is right the o rings your looking for are the oil galley o rings that go where the oil passages are from the pump to the filter and back through the cover to the rear bearing. The only time the pump o ring needs to be replaced is if you remove the pump, as far as I know. |

Don't see why that o ring would need to be replaced, unless disassembled. As for gasket, you need to buy another as it is a shim needed for the crank bearings. Permatex is used with gasket for best result |

The oil galley o rings do need to be changed each time the case is removed. They aren't really o rings, they are taller and compress when the case is installed . |
