For Army Oil Analysis Program (AOAP), refer to TB 43-0210. The AOAP laboratory
recommendation to change oil and filter will apply; however, oil and filter changes will not exceed
the change interval (calendar, miles, or hours) established by the manufacturer during the warranty
The AOAP sampling interval for the hydraulic system is scheduled to be published in
the next change to TB 43-0210, Appendix F.
Explosions of air inflated earthmoving tires have resulted from heat induced gas
combustion inside the tires. The heat generated by welding or heating rim
components, external fire, or excessive use of brakes can cause gaseous combustion.
A tire explosion is much more violent than a blowout. The explosion can propel the
tire rim and final drive components as far as 460 meters (1500 feet) or more from the
machine. Both the force of the explosion and the flying debris can cause personal
injury or death and property damage. All personnel should be aware of this danger
and the actions to take to minimize the risk.
Proper air inflation equipment and training in its use are necessary to avoid possible
over-inflation. A tire blowout or rim failure can result from improper or misused
Check and service (see TM 5-3805-260-10 and TM 9-2610-200-24). Proper inflation pressure
is 40 psi for the tractor and the scraper.
