Title: Johnson help
Post by: Marvin Denny on March 23, 2011, 02:11:28 PM

  I would like to get some help identifying a Johnson CS  shaft. not the BB, just the standard CS.  I would also like to get a thrust washer for an old small case Johnson.  It is the one with a "D" shaped hole.  Not the compression cone. I am sorting out my Johnson parts.

Marvin I have this random thrust washer I don't know where it came from.

diam ID .346, .317 at the flat.  .873 OD

.340 thick on the raised ring on back,  .322 thick below the ring.

It looks like this, and even has the slight taper on the edge of the flange.

 Nope Greg, That one is about 0.010 inch too big in the ID at both places, and 0.020 inch too thick.

  That one probably is for a later model than mine

  Thanks for looking.
