I am replacing the flywheel housing roller bearing, seals and slip rings in my 1983 Volvo Penta AQ125A motor with 270 outdrive. I am having trouble getting the shaft all the way through the the roller bearing to attach the ring clip to the shaft. Is this something that has to be pressed on by a machine shop or am I going at it incorrectly. I have attempted to drive it on but I am concerned about damaging the roller bearing or shaft. My seloc manual does not address this issue and the diagram really does not help. any help would be appreciated.<br />mjh
