Thanks for the information.
I went searching for engine service maintenance information about the 1966 CL77, and came across a site where some fellows had been chatting.
One contributor said the engine oil capacity was 1.5 quarts and the recommended oil change frequency was supposedly 600 miles.
Until today, I hadn't paid any attention to the crankshaft, itself. When you spoke of roller cage bearings on the crankshaft, I just had to look see what I could find.
I spotted the lower end of the 1 piece connecting rods had to utilize roller bearings, too. Oh, look there, a cam chain sprocket between the 2 inboard bearings.
WOW! The CL77 crankshaft assembly is press assembled like a 2 stroke engine crankshaft assembly would be. WOW, AGAIN!
Very fortunate to have found the crankshaft assembly was still in good condition.
