FAQ

Does this manual cover the technical specifications for the New Holland LB115.B 4-wheel steer variant? Yes. The manual provides comprehensive coverage for the entire LB Series, specifically detailing the 108 hp (79 kw) LB115.B and LB115 models. It includes specialized sections for the 4-wheel steer (4WS) configurations, including specific front axle data in Section 25 and steering system parameters in Section 41 to ensure accurate servicing of these high-spec models.

What is the primary relief valve pressure setting required for the LB series hydraulic system? To maintain peak breakout force and system safety, the main relief valve must be calibrated to 210 bar (3045 PSI). This technical benchmark is critical for the Husco and Rexroth control valves used across the product range, ensuring that the load-sensing, flow-sharing hydraulic circuits operate within factory design limits.

Is it possible to find detailed wiring diagrams and electrical system schematics in this document? Absolutely. Section 55 is dedicated entirely to the electrical system, providing full-color wiring diagrams and circuit maps for both North American and International machine variants. These schematics cover everything from the starting motor and alternator circuits to the complex electronic controls for the powershift transmission and the cab's auxiliary power sockets.

Can I find specific instructions for overhauling the braking system on models with 4-wheel steering? Yes. Section 33 contains specialized maintenance insights for the braking systems, distinguishing between standard configurations and those equipped with 4WS. It details the service procedures for the oil-immersed multi-disc brakes and provides specific torque sequences for the master cylinder assembly to prevent leaks and ensure consistent stopping power.

What are the benefits of using this digital manual for urgent field repairs and diagnostic troubleshooting? The digital format allows for instant keyword searching, enabling technicians to immediately locate high-utility diagnostic flowcharts and logic-based fault-finding trees. This is particularly vital for identifying engine or hydraulic malfunctions in the field, where the ability to print specific high-resolution pages—such as the planetary reduction exploded views—ensures that technicians have the exact factory data needed at the machine without risk of damaging a physical book.
