Re: 1936 J-80 Johnson water pump plunger

[Anonymous]

I believe that J-80 uses the same plunger and drive shaft gear/cam as the A, A-25, J-25 and J-65. If so I may have the parts you need. I think that sometimes water got into the gearcases causing that cam to rust which in turn chewed up the brass plungers. I have some that were so badly chewed up that they totally went through the botom of the plungers. I had some plungers made a few years ago. If you are interested I would send you a photo of the parts I have. If they look like what you could use, I’ll sell you both for $20 including mailing.
