Title: Re: Oil leak from oil filter cover! Post by DragBikeMike on 01/16/21 at 14:03:46 Greetings Espen, I hope we can help you with your leak. The cover is sealed by an o-ring. The sealing surfaces on the clutch cover and the groove in the filter cover must be free of defects. Visually examine those sealing surfaces and make sure there are no pits or deep scratches. If you can, take pictures so we can see the sealing surfaces. Post the pictures. Look at the o-ring. Makes sure it is not cut or deformed. If it comes out of the groove when you assemble the filter and cover, it will get pinched. If that occurred, it will be visually evident. Again, post picture. It is easy to install the filter backwards. If the filter is installed backwards, it blocks oil flow and the filter cavity pressure goes off-scale high. That usually results in the filter cover getting blown off, but I suspect it could also result in leaks at the o-ring seal. Make sure the filter is installed correctly. The big open hole in the filter faces in toward the crankshaft and goes over the raised boss in the clutch cover cavity. This shows the big open hole. |

Title: Re: Oil leak from oil filter cover! Post by DragBikeMike on 01/16/21 at 14:07:43 This is the raised boss in the clutch cover that the big open hole in the filter goes over. Note that there is an o-ring around the boss. It seals the filter to the clutch cover so that oil can't run around the filter into the engine. Its a small o-ring about 1/2" diameter. |

The small round thing in the center is a bypass relief valve. If the filter gets too dirty, the relief valve will open and let oil bypass the filter. |

Title: Re: Oil leak from oil filter cover! Post by DragBikeMike on 01/16/21 at 14:22:13 In summary: Check your sealing surfaces and o-rings. Make sure there are no pits or scratches. Post pics if you can. Verify that you filter is oriented correctly. Big hole facing IN toward the crankshaft, bypass relief facing OUT toward the filter cover. You also should have a spring (13) between the filter cover (11) and the filter. You might find this exploded view helpful. |

Title: Re: Oil leak from oil filter cover! Post by EspenA1982 on 01/17/21 at 05:26:22 Hey guys and thanks for all the help, i drained the bike and opened the oil filter cover. The o ring in the cover was not pinched but there was a little bit dust on the o ring! But both of the o rings looked perfect :) ill try to upload the photos but they are to big, so i need to convert them. |

Title: Re: Oil leak from oil filter cover! Post by DragBikeMike on 01/17/21 at 23:23:54 Your picture of the cover shows some very minor pitting in the o-ring groove and also what appears to be paint or powder coat. Use some abrasive paper to clean up the groove. Minor corrosion here. |

Title: Re: Oil leak from oil filter cover! Post by DragBikeMike on 01/17/21 at 23:24:40 Paint/powder coat here. |
