July 22, 200917 yr We are going to refit main bearings in friends bike tomorrow, I seem to remember something about bearing on flywheel side having to line up with an oil feed hole. Which hole does it line up with and how do we make sure they line up when bearing is tapped in?-cheers.
July 23, 200917 yr Draw a line with a Sharpie from the hole to the edge and side of the bearing, also mark the case. One hole for oil to feed into and the other for it to get out. Don't beat the bearings in, use a press. Mark.
July 23, 200917 yr Just a remark: The new bearings with hole came in 2005 or 2006. Before that there is a narrow bearing with a "open" shim between bearing and seal where the opening have to line up with the hole in the casing. I am talking lhs now. If it is the old type I would seriously concider change to the new type. To do the change you "only" have to remove the sleeves on the crankshafts. "Only" in "" becouse this can be a little tricky to get them off... On the new type there is just one hole. That is for the outflow. For the "inflow" there is a narrow passage in the casing. Be sure that the outer teflon seal doesnt clogg that passage. -Jan Edited July 23, 200917 yr by JanDyb
