New Holland B90B / B90BLR / B100B / B100BLR / B110B / B115B Service Manual (P/N 87643846B)

This 1,110-page PDF covers the New Holland B-Series loader backhoe machine systems for the B90B, B90BLR, B100B, B100BLR, B110B, and B115B. It is the machine-side service volume used for drivetrain, axle, brake, hydraulic, steering, electrical, cab, loader, and backhoe repair work.

• Covers Turner COM-T4-2025 Powershuttle and Dana T16000 Powershift transmission service, including removal and installation, internal disassembly and assembly, clutch and gear components, hydraulic test points, power-flow information, stall testing, fault finding, and special tools.
• Details Carraro 2WD, 4WD, and 4WS front axles, the CNH D46 2WS rear axle, and the Carraro 26.32M 4WS rear axle, with differential and pinion work, bearing and shim setup, axle disassembly, steering-angle checks, and fault finding.
• Covers the Casappa hydraulic pump, Rexroth mechanical and pilot control valves, load-sensing circuits, relief valves, swing system, hydraulic control levers, and individual loader/backhoe cylinders, with removal, teardown, inspection, reassembly, and hydraulic fault diagnosis.
• Includes model-specific electrical diagrams and diagnostic procedures for Powershuttle ROPS and cab machines, Powershift cab machines, and 4WS configurations, plus speedometer calibration, diagnostic-display self-test, onboard error-code retrieval, component testing, and 4WS steering sensor/control-unit checks.
• Provides brake-system service including parking-brake adjustment and brake bleeding, 2WS/4WS power-steering repair and fault finding, HFC-134a air-conditioning testing and service procedures, and loader/backhoe attachment removal and installation.
• Covers loader bucket and loader-frame removal, center-pivot and sideshift backhoe removal, bucket and dipper work, telescopic-dipper service, stabilizer systems, and the mechanical and hydraulic backhoe-control versions.

Coverage and Configuration Matching

The manual’s configuration tables are important because the B-Series is not one uniform machine. It distinguishes Powershuttle and Powershift drivetrains, 2WD and 4WD, 2WS and 4WS steering, sideshift and center-pivot backhoes, cab and ROPS versions, mechanical and pilot controls, and short, long, and telescopic dipper arrangements. It also identifies the installed engine builds: F4GE9484C601 for the mechanical 97 HP application, F4HE0484GJ102 for the electronic 97 HP application, and F4HE9484CJ102 / F4HE9484CJ103 for the 110 HP machines. Power-steering coverage distinguishes the Danfoss OSPC 125 LS used with 2WS from the OSPC 160 LS used with 4WS.

One scope point matters before purchase: this is the Loader Backhoe service volume. New Holland identifies the full service set as two volumes and lists a separate Engine Service Manual, Print No. 87659057A. This machine volume provides engine identification and specification data, but full internal engine repair belongs to that separate engine publication.

Drivetrain, Axle, and Hydraulic Repair Depth

Transmission coverage goes well beyond basic specifications. The Turner section maps transmission oil flow, forward/reverse clutch operation, pressure-test locations, 2WD/4WD internal components, synchronizers, shafts, clutch packs, shimming, removal, teardown, assembly, and fault diagnosis. The Dana section adds its own hydraulic diagram, pressure checkpoints, cooler circuit, power-flow charts, gear-and-clutch layout, removal/installation, internal component service, and microprocessor fault-finding material.

Axle repair is broken out for the Carraro 26.00, 26.16, 26.28, and 26.32M assemblies as applicable, along with the CNH D46 rear axle. Coverage reaches into wheel hubs, reduction groups, differentials, pinion groups, bearings, shims, steering knuckles, and setup checks. Hydraulic coverage is similarly configuration-specific: separate circuit diagrams are provided for 2WS sideshift mechanical machines, 2WS sideshift pilot machines, 2WS center-pivot pilot machines, and the corresponding 4WS configurations. Rexroth loader and backhoe control valves, the load-sensing flow-sharing system, Glide Ride accumulator, swing circuit, and the loader, bucket, boom, dipper, telescopic, stabilizer, swing, and sideshift-lock cylinders are addressed.

The technical sections also provide the related component-specific torque tables, hydraulic pressure and flow test specifications, fluid-capacity data, wear and inspection limits, shim and end-float data, and electrical test specifications without reducing the manual to a list of isolated values.

Diagrams, Electrical Testing, and Diagnostics

Useful visual references include the Powershuttle oil-flow and supply diagrams, Dana T16000 hydraulic and power-flow diagrams, 2WS/4WS hydraulic schematics, Powershuttle/Powershift/4WS electrical diagrams, and 4WS steering-control connector and solenoid-operation views. The electrical section also contains fuse/relay and connector identification, starting and charging-system tests, battery checks, ground-point information, and component-level switch and sensor testing.

For B100B, B110B, and B115B machines, the diagnostic-display section covers setup functions, instrument self-test, warning messages, and stored onboard error-code retrieval. Powershift fault finding includes LED-based fault codes and test modes, which helps separate electrical control problems from hydraulic or mechanical transmission faults before repair work starts.

Factory Tools and Repair Cautions

The manual names service tools rather than leaving critical setup work generic. Examples include the Carraro false pinion 380002219 with false differential box tools 380000407 and 380000440 for pinion-depth setup, transmission pullers and clutch tools such as 380002683 and 380002689, and hydraulic-cylinder head wrenches including 380000721, 380000724, and 380000725.

There are several repair traps worth knowing. During Turner transmission case separation, bearing cones and shims can fall from the rear case; the manual specifically calls for marking their original locations so the correct stack-up is preserved. On the hydraulic multi-plate 4WD clutch, the outer piston seal has a required orientation; installing it backward can compromise clutch sealing. The hydraulic pump section also requires bearing blocks to be identified before disassembly so paired components return to their original positions.

The manual repeatedly requires raised loader/backhoe structures to be mechanically supported rather than held only by hydraulic cylinders, hydraulic pressure to be relieved before circuits are opened, and the battery to be isolated where specified. Air-conditioning repair requires proper HFC-134a recovery and recharge equipment. Use the applicable model and configuration section before beginning any repair.
