Re: 1936 Johnson A-80 4.5 hp power head HELP!

[Buccaneer]

Thanks for the replies. Earlier I was looking in the 3rd edition
Johnson manual. While it doesn’t show the A-80 Johnson,
it did show a "K" series power head that looked very
similar in construction.
It mentioned two compression rings on the center bearing as you mention.
I did NOT say anything special to do in order to pull out the crank shaft.
Perhaps there’s a groove worn in the center bearing from the lower
ring, and the groove is catching on the upper ring, or as you mention,
the flange by the bottom crank pin is "catching".
Will try oiling things up tomorrow, twist, tap, etc., and see if pops
free.
Wonder if some thin shim stock strips inserted over the flange would
expand the bottom ring, allowing the flange to pass by?
Hope the rings are not broke……. may not find them at Walmart 😮
Richard, I’ll inspect the "backfire baffles", and if at all deteriorated,
will remove them.Thanks!

Prepare to be boarded!
