Spent half a day at my buddy's shop assembling the crank/case today. Parts washer to clean cases, then flush all the ports, rinse, blow dry, rinse again and final blow out. Press out the old main bearings and install the new ones.
Old cases, but all new internals..
S&S 4 3/8 crank; S&S T3 Oil pump/cam plate, Suburban 9cc raised pistons;
Still have to bore/hone cylinders, and heads are out to get some work.
Thanks Chad, for use of the tools and the space.
