New to the forum, so I hope this is the right spot to ask this question. I have a 1979 Blackman boat with a Volvo AQD40 A and a 280 DP outdrive. I am in the process of replacing the spider/u joints and wanted to lube the gimbal bearing. I have a manual stating that the grease zerk for the gimbal bearing was on the housing behind the helmit, but there doesn't appear to be a zerk in there. I looked around the bellhousing and didn't see one there either. Any suggestions?
