Replace mains?

[trp3141592]

Hi all,

I am hearing a deep bass-drum rumble in the low end of the '37 Roadmonster's engine at idle speed. It goes away when oil pressure comes up at higher engine speed. Anticipating a main bearing issue, I am wondering if the mains can be replaced via removing the pan and without pulling the engine. Has anyone done this and can share the experience?

Thanks,

Thomas, it has been a while[ long while] since doing this, but yes you can.
