PREVENTIVE MAINTENANCE CHECKS AND SERVICES,
INCLUDING LUBRICATION INSTRUCTIONS - Continued
INSPECTION - Continued
There are some common items to check all over the trailer. These include the following:
Bolts, clamps, nuts, and screws: Continuously check for looseness. Look for chipped paint, rust, or
corrosion around bolt and screw heads and nuts. Tighten them when you find them loose. If tools are not
available, notify the next level of maintenance.
Welds: Many items on the trailer are welded. To check these welds, look for chipped paint, rust
corrosion, or gaps. When these conditions exist, Operators must notify Field Level Maintenance on DA Form
Electrical wires, connectors, and harnesses: Tighten loose connectors. Look for cracked or broken
insulation, bare wires, and broken connectors. If any are found, Operators must notify Field Level
Hoses and fluid lines: Look for wear, damage and leaks, and make sure clamps and fittings are
tight. Wet spots mean a leak. A stain by a fitting or connector can also mean a leak. When you find a leak,
Operators must notify Field Level Maintenance.
LUBRICATION SERVICE INTERVALS - NORMAL CONDITIONS
For safer, more trouble-free operations, make sure that your trailer is serviced when it needs it. Proper
lubrication and service intervals which are the responsibility of the Operator/Crew and Field level
maintenance are found in this work package.
Intervals (on-condition or hard time) and the related man-hour times are based on normal operation. The
man-hour time specified is the time needed to do all the services prescribed for a particular interval. On-
condition (OC) oil sample intervals shall be applied. Change the hard time interval if lubricants are
contaminated or if operating the equipment under adverse operating conditions, included longer-than-usual
operating hours. The calendar interval may be extended during periods of low activity. If extended,
adequate preservation precautions must be taken. Hard time intervals must be applied during the warranty
Intervals shown in this work package are based on calendar times. An example of a calendar interval is: Q,
which means quarterly (every three months). The lubrication is to be performed at whichever interval
indicated for the trailer.
