Key Notes:
Part Number: A137741
Replaces: A37927
Weight: 13 lbs (5.9 kg)
Side: Left-hand
Splines: 16 tapered splines
Drive Type: Two-wheel drive (2WD) only
Material: Heavy-duty cast construction
Location: Left-hand steering assembly — mounts to the front axle steering knuckle spindle and connects to the tie rod end to transmit steering input to the left front wheel on applicable Case backhoe loaders
Application: Left-hand steering arm — the cast steering arm that transfers steering cylinder force through the tie rod to achieve front wheel steering on Case 480B, 480CK, 580B, and 580CK backhoe loaders
Common Use Case or Symptoms: Use when the left-hand steering arm is cracked, bent, has worn or stripped splines, or has damaged tie rod mounting holes — a failed steering arm causes loss of left-front steering control, excessive steering play, and potential front wheel misalignment on applicable Case backhoe loaders.
