If it ran long enough to get hot [red *cherry juice* hydraulic fluid helped if the temperatures were above freezing] the internal parts would get soft and deform out of shape. Given a second/third gun to strip for internal parts, you could get through the Table Eight gunnery exercises okay, and when our battalion did in 1966, we became the highest-scoring tank battalion in USAREUR. Not because we outshot the tank division gunners in our crapped-out old M60s [except for the three M60A1s we had in HQ company] but because we could keep our M73s going.
