replaced

I recently got a clean, low hours HS50 67061A (1975 I believe). Can the original 1" crankshaft be replaced with a 3/4" crank? I've seen a thread that discussed machining the 1" crankshaft down, but if replacement is possible with no resulting engine damage, that would be my preference. I may...
