John Deere 610B Backhoe Loader – Parts, Specs & Serial Numbers

Description:

The John Deere 610B Backhoe Loader, produced in the 1980s, was the top-tier model in Deere’s B-series backhoe lineup. Designed for heavy-duty excavation, utility trenching, and large-scale site development, the 610B delivered more digging depth, greater hydraulic capacity, and improved load control than its smaller siblings. Equipped with a turbocharged diesel engine, PowerShift transmission, and robust loader frame, the 610B is ideal for contractors and municipalities needing long-lasting power in a no-nonsense, mechanically driven machine.

Common Replacement Parts:

• Backhoe and loader seal kits

• PowerShift clutch discs and solenoids

• Wet brake discs and rear axle seals

• Loader pins and bushing kits

• Water pumps, belts, and radiator parts

Common Issues & Quick Fixes:

• Hydraulic Drift or Lag: Often caused by worn piston seals — rebuild with hydraulic cylinder kits

• Sticky or Unresponsive Shifting: Common with failing clutch solenoids — replace via PowerShift parts

• Brake Fade or Fluid Leak: Wet disc systems may require new friction plates — fix with brake rebuild kits

Pro Tips:

• The 610B’s extended digging depth makes it ideal for storm drain and septic work — but inspect the boom pins frequently for wear.

• Use the serial number to distinguish between early- and late-model control valve configurations.

• Keep the loader frame torqued to spec to avoid structural fatigue under heavy loads.

Serial Number Info:

• Location: Left frame rail near the loader tower or under the operator’s platform

• Serial Number Format: Begins with T0610BH_ _ _ _ _

• Always use the full serial number to identify parts, especially for hydraulics and transmission variants.
