Did maintenance discipline change Chieftain tank readiness?

Were Chieftain tanks effectively designed to break down near their bases in Germany?

In one anecdote, a unit led by an unusually maintenance-focused sergeant major kept its Chieftains working more reliably by servicing the linkages among the wheels, suspension, and engine power.

The answer uses an anecdote about three Chieftain units in Germany whose sergeant majors imposed different levels of maintenance discipline. The unit that practiced especially intensive preventive maintenance reportedly achieved better vehicle availability. The connections among the wheels, suspension system, and engine power are identified as a recurring source of trouble that careful servicing could reduce. The comparison to naval overmaintenance makes a broader readiness point: demanding equipment can appear more or less reliable depending on how consistently its weak points are maintained. The story came from the sergeant major whose unit supplied the favorable example, so the attribution matters.
