Reply To: 1955 25 HP Johnson Loose Conn Rod Bushings

[DAN ANDERSON]

Gary, I am now confused. I agree 100% that the ’56 wrist pin bearings were of poor design and caused problems, but I think they were around longer than that? I have found them in ’57 35hp Lark engines. See link:

That is the original bearing for the wrist pin that it takes two per rod. Still available today. I did not find that the #377260 could be put in the older rod. Some may be heavy enough walled to be teamed, but most are too thin? The 1958 RDE-19 shows the newer style wrist pin bearing you mention. That is the bearing I prefer to use. I just put in the complete conn rod assembly. Just my preference.

I think Mumbles has made bronze bushings for the original conn rods, but I would rather have a wrist pin bearing, myself.
