Part of the New Holland Repair Manuals.
This is the full factory workshop and repair manual for the New Holland LB75.B, LB90, LB110 and LB115.B backhoe loaders, the same service information a dealer technician works from. It is split into 43 chapters covering the engine, the DPS fuel system, turbocharger, cooling and lubrication, both the Powershuttle and Powershift transmissions, the two-wheel, four-wheel-drive and four-wheel-steer axles and brakes, the HUSCO and Rexroth hydraulic systems with pressure and flow testing, the loader and backhoe cylinders, steering, cab heating and air conditioning, and a full electrical section with the wiring diagrams. Every chapter carries the specifications, fault-finding tables and step-by-step overhaul procedures, so you can chase a hydraulic, transmission or electrical fault and put it right instead of guessing.

New Holland LB75.B, LB90, LB110, LB115.B Common Problems This Manual Covers
Hydraulic pump loses pressure or the loader and backhoe slow down under load.
Start with the Chapter 22/24 pressure and flow tests to confirm the pump is down rather than a relief valve. Contaminated fluid and worn pump seals are the usual cause, and Chapter 25 gives the pump removal, inspection and overhaul steps with the clearances.
Manual Section: Chapter 25 - Hydraulic PumpBackhoe boom or dipper drifts down or sags when held raised.
Drift is normally leaking cylinder seals or a faulty holding/pilot valve, not the pump. Chapter 26 covers the cylinder removal, seal-kit replacement and reassembly, and Chapters 21/23 cover the valve spool seals that hold a raised load.
Manual Section: Chapter 26 - Hydraulic CylindersTransmission slips or will not engage a gear.
Worn clutch packs or a failing transmission solenoid are the usual causes. Chapters 8 to 13 cover the Powershuttle and Powershift transmissions with the fault-finding tables, solenoid checks and the clutch-pack overhaul procedure and specifications.
Manual Section: Chapter 9 - Powershift TransmissionEngine overheats even though the coolant level is fine.
With no coolant loss the cause is usually a blocked radiator core or a tired water pump. Chapter 7 (Cooling System) gives the fault finding, pressure test and the water-pump and radiator overhaul steps to confirm and fix it.
Manual Section: Chapter 7 - Cooling SystemFrequently Asked Questions
Does this manual include the wiring diagrams for the LB75.B, LB90, LB110 and LB115.B?
Yes. Chapter 33 (Wiring Diagrams) carries the electrical schematics for both the North America and rest-of-world builds, alongside the system-general, starter, alternator, battery and service-diagnostics chapters, so you can trace an electrical fault properly.
The backhoe boom drifts or sags when raised - what does the manual cover?
Boom drift is usually leaking cylinder seals or a faulty pilot/holding valve. Chapters 21 to 26 cover the hydraulic circuits (both HUSCO and Rexroth builds), pressure and flow testing, the pump and the cylinders, with the overhaul steps to reseal a leaking boom cylinder.
Does it cover both the Powershuttle and Powershift transmissions?
Yes. Chapters 8 to 13 cover the Powershuttle and Powershift transmissions and the 4x4 compact shuttle, including the operating lever, description and operation, fault finding and full overhaul with the four-wheel-steer variants.
How do I diagnose a hydraulic pressure or flow problem?
Chapters 22 and 24 are dedicated to fault finding, pressure and flow testing for the HUSCO and Rexroth hydraulic systems. They give the preliminary checks, test-point pressures and the diagnostic sequence to find a worn pump or a stuck valve.
What engine power do these backhoes make?
Rated engine power runs about 84 to 90 hp on the naturally aspirated builds and 90 to 98 hp on the turbocharged builds (ISO and CEE ratings). The full per-model figures are in the General Specifications chapter.
