Backhoe Control Valve Resealing Kit for Case 580D

Fits Models At A Glance:

• Case Backhoe Loaders: 580D
• Important Note: This kit does NOT fit the 580 Super D — the 580 Super D is a turbocharged machine with a different control valve configuration. Confirm your model is a naturally aspirated 580D before ordering.

Key Notes:

• Weight: 0.4 lbs (0.18 kg)
• Kit Type: Backhoe control valve complete resealing kit
• Total Pieces: 95 seals and O-rings
• Application: Complete reseal kit for the backhoe control valve — contains all O-rings, back-up rings, and valve spool seals needed to fully reseal the backhoe control valve on Case 580D backhoe loaders, restoring hydraulic pressure integrity across all valve sections including boom, dipper, bucket, swing, and stabilizer circuits
• Note: This kit uses updated part specifications versus the 580C version — three seal and O-ring positions have been revised for the 580D valve. Do not substitute the 580C kit on a 580D machine

Includes:

• Section port O-rings — large and small
• Outlet internal O-ring
• Spool plug O-ring
• Valve spool O-rings — multiple sizes
• Valve spool seals
• Circuit relief poppet O-rings — updated spec
• Circuit relief piston O-rings
• Circuit relief valve O-rings — updated spec
• Back-up rings
• Stabilizer spool O-rings — updated spec
• Stabilizer seat O-rings
• Stabilizer plunger O-rings

Common Use Case or Symptoms: Use when the backhoe control valve is leaking externally at section ports, spool bores, or stabilizer sections — external leaks at the control valve cause hydraulic oil loss, reduced system pressure, sluggish or drifting backhoe function, and contamination of surrounding components on Case 580D backhoe loaders.

Why Choose Broken Tractor:
