John Deere 410B Backhoe Loader – Parts, Specs & Serial Numbers

Description:

The John Deere 410B Backhoe Loader, built from the early to mid-1980s, was the upgraded version of the original 410, offering more breakout force, enhanced hydraulic flow, and an improved transmission for smoother gear engagement. This model was designed for heavy-duty excavation, material loading, and utility work — perfect for large contractors or municipalities needing serious digging power and a strong front-end loader. Despite its age, the 410B remains a dependable, jobsite-proven workhorse thanks to its durable construction and easy-to-service systems.

• Daily Greasing Points: Loader pivots, backhoe arms, stabilizers

Frequently Replaced Parts:

• Hydraulic cylinder seal kits

• Loader and backhoe pins and bushings

• Clutch discs and release bearings

• Brake linkage parts and pads

• Cooling fans, water pumps, and belts

Common Issues & Quick Fixes:

• Hydraulic Leaks: Often occur at boom or dipper cylinders — resolve with hydraulic rebuild kits

• Clutch Slippage: Caused by worn friction discs — restore performance with 410B clutch replacement parts

• Brake Fade or Pedal Drop: Fix by replacing worn linings or adjusting linkage — shop complete brake kits

Pro Tips:

• Grease loader tower and backhoe swing pivots daily to avoid early pin wear.

• If loader arms “drift” down while parked, inspect and reseal lift cylinders.

• Clean radiator fins frequently — the 4239D engine can overheat under load if airflow is restricted.
