TM 5-4210-230-14&P-1 VEHICLE MAINTENANCE WHEELS-DISC (Flanged Nut) 1. Mounting faces of the hub, wheel and nut must be free from dirt or excess paint.  Mounting faces which have been damaged from wear or abuse must be repaired or replaced. 2. Right hand threads are used on both sides of the vehicle when the flanged type nuts are used. 3. Tighten flanged wheel mounting stud nuts to 540 Nm (400 ft. lbs.). It is good practice to recheck lug nut torque of any wheel installation after the first 80 km (50 mi.).  The seating of parts may allow the torque to drop off.  If the torque has dropped off, retorque and check again after another 80 km (50 mi.).  If torque has dropped off a second time, recheck closely for a flush fit to hub or brake drum; look for any type of interference and correct.  Once the proper torque is retained after the initial installation, it is advisable to periodically check the torque at regular maintenance intervals. CAUTION When mounting "NEVER" hammer on a fully or partially inflated assembly. To prevent possible bodily injury or fatality, these Safety Precautions listed below must be strictly observed. CAUTIONS 1. Always deflate tires completely before removing locks or side rings. 2. Always inspect and clean all parts before assembly. 3. Always inflate tires in safety cage. 4. Always use a "clip-on" air chuck with remote valve to inflate tires. 5. Never mix parts of different types or size. 6. Never use cracked, bent or badly rusted parts. 7. Never reinflate flat tire on vehicle--use the spare. 8. Never add air until certain each side or lock ring is fully seated. 9. Caution must be observed when selecting the proper replacement part, an incorrect fit is dangerous.  The side ring, locking ring and base must all fit correctly. 10. Do not heat or weld aluminum wheels in an attempt to straighten or repair severe road damage.  The special alloy used in these wheels is heat-treated, and uncontrolled heating from welding torch affects the properties of the material. 11. To avoid possible corrosive affects to aluminum wheels, use only a slight amount of water and neutral soap (similar to Ivory Snow, Dreft, etc. -no detergents) when mounting tires.  Do not use commercial rubber lubricants. 12. Do not stand unprotected in front of side ring when inflating tire.  If no protection device is available, stand wheel and tire close to a solid wall with side ring facing the wall.  Inflate tire from side opposite ring.  If no solid wall is available, place tire and wheel on floor with side ring next to floor (down) and inflate from above keeping body AWAY from directly in front of or above tire at all times. 13. Inflate  tire  until  tire  beads  are  firmly  seated  against  rim  flanges.    Never  inflate  above  40  psi  to  seat  beads.    Completely deflate tire by removing valve core; then reinflate tire to recommended pressure. 14. When installing new front or rear rims, the size and material of new rims must be equivalent or the same as specified by the ORIGINAL  MANUFACTURER.    Installation  of  larger  than  recommended  rims  can  include  severe  overstress  of  axle  and brake components which could result in serious personal injury in the event of component fatigue. 15. When mounting "NEVER" hammer on a fully or partially inflated assembly. 15
