Wilbur Greenies are not the most sophisticated but they won't send you broke either with big repair bills and replacement parts all the time. Very rugged machine that you are able to repair fairly easily. You can contact the Loctite distributors (I forget who they are) and tell them what you need to achieve and they can put you onto what they think is best. Some of the Loctites are very strong, I have been told that one of the drive gears in a BMW gearbox is only fitted using Loctite on a straight shaft so it must be pretty good. I will check the bolt pattern tomorrow because it is a question I asked some time ago and did not get an answer. Good chance it is the same as the small Briggs motors from those measurements
