OS 91 bearing replacement

Post by Cgb68 » Sun, 16 Apr 2000 04:00:00



Im reinstalling the bearings on my OS 91.  I see the cam has a mark on it for
alignment but Im not sure what it aligns up to?  Can anyone direct me in
replacing the camshaft correctly?

Thanks for you help

With the crankshaft at top dead center (or bottom dead center) the mark
can go either straight up or straight down.  It makes no difference what
combination you use, just whichever is easier for you to see.
