My layshaft bearings were showing copper. Sure, they'd have survived for many years and miles, but they were indeed worn. So was the rear main bearing, which also had a bunch of captured junk imbedded in it.

Splitting the case and replacing all those bearings was about the easiest part of the rebuild. The closer you get to the center of the engine, the simpler it is. Most of the complex stuff is bolted to the OUTSIDE of the engine. When all that complicated stuff is removed, the next most complex part is the heads, cams, chains. Then P&Cs, rings, wrist pins, etc.

Once you're down to the case, it's just a few nuts and bolts and Voila! You're looking at a crankshaft, an oil pump and a layshaft. That's it.
