Rebuild tidbits and removing camshaft

[NCDiesel]

I am rebuilding my K301 from my 1966 model 123 and I was SUPER excited to see how clean it was and the fact it is a standard untouched engine. Very minimal ridge and no scoring: Still has original standard piston. Cylinder bore and piston measurements are all bad by a little. However between ring wear and cylinder wear, ring gap was WAY off. Probably the reason for the blow-by and lack of power that caused me to rebuild.

Interestingly, everything else is fine. Crank pin measurement, wrist pin, etc.

However, I now need to tear down the governor and the camshaft so I can get the block cleaned and machined. Both of these looked like press-out jobs. However, my initial attempt created no movement and seemed to require more force than I felt comfortable applying. Neither the manual or my inspection indicated the presence of rings or clips that would prevent the press-out. The manual was pretty clear in which direction it should be pressed out, so I think I have that part right.

Am I going about this all wrong? Or am I just being to cautious and should go ahead and really lean into the press?


Also, any tips or tricks ?

Thanks in advance!
