Preventive Maintenance
In order to maintain efficient ready mixed concrete truck fleets, all producers recognize the need
for Preventive Maintenance (PM). The concept of
PM is to carefully service and inspect each truck
in the fleet at regular intervals to minimize the
-number of breakdowns. A good PM program predicts breakdown frequency and necessary repairs.
This allows servicing to be scheduled at optimum
times before the breakdown occurs. Typical PM
drain intervals are calculated in terms of hours of
engine running time. Historically, manufacturers have recommended PM drain services at a
frequency of about 300 engine hours. Our survey results reveal that about 83% of producers
base drain intervals on engine hours and, surprisingly, only 7% base their drain intervals on
calendar days.
