Key Notes:

• Part Numbers: AT394501, T357835
• Type: Greaseable self-aligning swivel ball bushing (spherical bushing) with oil groove
• Design: Spherical ball bushing that swivels to self-align with the pin, plus an oil groove that spreads grease across the bushing face
• Weight: 7.20 lbs (3.27 kg)
• Serial Number Notes: On the 950P dozer, fits machines from Serial Number 07442 and up. All other models listed fit every serial number.
• Application: Used at a pivot joint that has to swivel as well as rotate, letting the pin and linkage self-align under load while staying greased.
• Condition: Replacement Part for John Deere Equipment

Common Use Case or Symptoms: Use when the pivot has play or knocks, the bushing won't take grease, or the ball is worn, scored or seized in its housing — a worn swivel bushing lets the joint slop and wears out the pin and bore.
