John Deere 710B Backhoe Loader – Parts, Specs & Serial Numbers

The John Deere 710B Backhoe Loader, released in the late 1980s, was the largest and most powerful model in Deere’s B-Series lineup. It was built specifically for contractors needing maximum reach, breakout force, and loading capacity. With a John Deere turbo diesel engine, heavy-duty PowerShift transmission, and high-capacity hydraulic system, the 710B delivered serious performance in highway, utility, and pipeline construction. Its massive size and reach set it apart from all other Deere backhoes of the era.

• PowerShift transmission solenoids and discs

• Brake discs and rear axle seals

• Loader bushings and pivot pins

• Engine cooling parts – water pumps, belts, thermostats

Common Issues & Quick Fixes:

• Boom drift or loader droop: Worn cylinder seals — rebuild with seal kits

• Hard shifting or transmission slipping: Often caused by solenoid or clutch wear — solve with PowerShift rebuild kits

• Brake fade or slow engagement: Replace worn discs and service axle seals with brake kits

Pro Tips:

• Use extreme caution when digging at full extension — the 710B’s reach and weight require solid stabilizer contact.

• Check swing post and dipper pivot regularly — these high-stress areas benefit from daily greasing.

• Always confirm part fitment with serial number due to mid-production updates to hydraulic and axle configurations.

Serial Number Info:

• Location: Left side frame rail near loader tower or under operator platform

• Serial Number Format: Begins with T0710BH_ _ _ _ _

• Serial number is crucial when ordering PowerShift or axle parts due to production changes during the model run.
