If you have a 3/4 inch crack on a tripod jack, what action is required?

• A. Replace jack legs that are severely dented, mashed, and/or show two visual cracks one-half inch long or greater.
• B. Stop drill and weld cracks less than one-half inch.
• C. Retire the jack and replace the entire assembly.
• D. Continue operation with inspection only

Answer: (A)

Cracks in load‑bearing tripod jack legs indicate fatigue and loss of structural integrity. When a crack is 1/2 inch or longer, or the leg shows severe damage, the part must be replaced rather than repaired. A 3/4 inch crack clearly meets this threshold, so the correct action is to replace the affected jack leg. This preserves the jack’s designed strength and prevents sudden failure under load. Stop‑drilling or welding cracks is not appropriate for a crack of this size on a primary support member, and continuing operation or inspecting only would ignore the evident defect. Replacing just the damaged leg is the proper remedy, unless there is damage to multiple legs or the entire assembly is compromised.
