This task covers:
Tool kit SC4940-97-CL-E12
Electrical tape (Item 36, Appendix B)
Wheel turning machine
Model 2012, Type A
DC welder 3431-00-276-0397
Brake lever equipment removed as required
Sander hose removed
Before wheel turning and recontouring are performed, wheel rim thickness and flange thickness
must be measured to determine if the results will meet Association of American Railroad (AAR)
Rule 41 specification requirements.
1. Refer to TM 55-2210-224-12 for inspection procedures. Inspect wheels for wear, sharp flanges, shelling, cracks, and
flat spots. Wheels will vary no greater than two tapes between wheels on same axle (1/4 inch (6.35 mm)) in
circumference or 0.080 inch (2 mm) in diameter. Wheel size between different axles can vary up to 3/4 inch (19.05
mm) in diameter. Defects greater than those outlined above will require removal of wheel sets from truck assembly.
