New Holland B90B–B115B Loader Backhoe Technical Documentation

This official publication (P/N 87643846B) is the primary reference for diagnosing and servicing the B-Series loader backhoes. Instead of guessing values, technicians get direct access to factory specifications, component identification drawings, and transmission logic.

• 1,110 pages of technical data, covering engine, drivetrain, hydraulic, and steering configurations for both 2WS and 4WS variants.
• Supported models include the B90B, B90BLR, B100B, B100BLR, B110B, and B115B.
• Instant digital download: Access the files on your device immediately after placing your order.
• Print specific schematics or pages directly for greasy shop-floor use.
• Lifetime account access ensures you can retrieve the manual even after a hard-drive failure.

Component and Systems Overview

The documentation details complete systems maintenance for the diesel engine, steering setups, and heavy-duty hydraulics. You will find precise data for both the Turner COM-T4-2025 powershuttle and Dana T16000 powershift transmissions, alongside servicing guidelines for Carraro front and rear axles. Complete machine disassembly and assembly procedures are fully mapped out, making this an essential tool for daily workshop operations.

Technical Specification Highlights

Having accurate numbers on hand prevents costly rework in the bay. The manual lists critical reference values, including engine torque outputs up to 516 Nm (380.58 lbf·ft) for the 110 HP variants. Engine displacement across all covered models is documented at 4485 cm3.

The hydraulic system capacity is specified at 118 liters, while the steer system pressure requires calibration to 177 ± 3 bar. You can also verify torque converter relief valve settings, documented at 10 bar for the Dana transmission. When working on the undercarriage, exact axle nut torque is provided—330 Nm for 2WS models and 700 Nm for 4WS configurations.

Please note that all figures and measurements mentioned here are strictly for general reference. Always rely on the complete OEM documentation and observe proper safety protocols before performing any hands-on mechanical work.
