120 AC question

[William Ahrens]

Mike 

Good to hear from you.  When installing these rings don't force them.  Will
could bend them or worse break groove in crank

 

Using a good after run oil on the rings and crank slide the crank with the
rings in bore until they contact the chamfer of crankcase.  Lightly pull on
crank shaft from the front and using a small screw driver assist rings in
groove while maintaining pulling pressure on front of crank.  Prior to
installation make sure on sharp edges are on crankcase chamfer that rings
will ride on.  It make it real hard if there any marks.

 

Good Luck

Subject: 120 AC question

 

I am finally, after 3+ years, putting a 120 AC back together.  On the
subject of the two rings on the crank shaft, what is the best way to
compress them so I can slide the crank as far fwd as it will go?  They
protrude quite a bit from the groove right now.  Your collective help is
appreciated.
