TM 9-2350-273-BD TRACK AND SUSPENSION Procedural Steps (Cont'd) Z. As an alternative to removing complete roadwheel arm assembly, the roadwheel arm can be tied up out of the way. 3. To tie a roadwheel arm up, remove torsion bar. 4. Position the vehicle across a ditch narrow enough to permit the front and rear roadwheels to support the weight of the vehicle and deep enough to permit the track to sag away from the defective roadwheel. If a ditch is not available, a trench can be dug. The vehicle in this position will allow the roadwheel assembly to drop and remove the stress on the torsion bar. 5. Remove the torsion bar by removing its capscrew and end plug, replace capscrew in torsion bar, and pry behind the capscrew head with a tanker's crowbar as shown. 6. Reposition the vehicle on level ground and remove the roadwheel. Lay a six-foot length of pipe across two torsion bar support housings, and tie the roadwheel arm in the raised position to the six foot pipe, steel bar, or 4 x 4 board, with rope or chain as shown. 7. Record the BDAR action taken. When the mission is completed, as soon as practicable, repair the vehicle using standard maintenance procedures. 9-10
