Both had prestart lube pumps with oil preheaters and coolers. I suspect the design included these system considering overhauling or repairs due to worn bearings was a major undertaking.
All consumer rated internal combustions engines from lawn mowers to the big diesels in a RV do wear very, very slightly each time they are started but even without the pre-lube capabilities the engines, most of the time, out last what ever they are bolted to. Also modern metallurgy have made vast improvements in metals used in engines extending the life far beyond what our fathers had. Local car dealer's advertisement - "200,000 is the new 100,000" is very true today.
