I agree w/Joe-give that crank a good visual first.Scrape the edge of a penny lengthwise on those journals-if any copper residue is left on the journal-you wanna drop it out for polishing/and/or a regrind.Also when you reassemble,be sure and put it all back together"WET".I use a 50/50 mix of SAE 30 non-detergent and STP for bearing jobs.Don't forget to check bearing clearances w/Plastigage at reassembly and crank 'er with the coil wire off just to be sure the new pump is gonna pump before you restart the 'ol 390.Good luck,BJ,Cannedband DJs :D
