Key Notes:

• Part Number: T80348
• Weight: 1.40 lbs (0.64 kg)
• Type: Blade pivot bushing — the replaceable wear bushing housed in the cross frame at the main center blade pivot point
• Application: Supports and guides the main blade pivot pin at the center connection between the blade assembly and the dozer's cross frame; allows controlled blade movement during lift, tilt, and float while absorbing the lateral loads of dozing
• Companion Part: Used with blade pivot kit AU13937 — the bushing is sold individually here; the complete kit (pin + bushing) is available separately as AU13937
• Origin: Made in USA
• Manufacturer: PVE Products

Common Use Case or Symptoms:
Use when there is excessive slop or play at the center blade pivot, the blade wanders laterally during straight dozing, or metal-on-metal contact is evident at the pivot joint — a worn bushing allows the pivot pin to shift under load, accelerating pin and cross frame bore wear and reducing blade control.
