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

This New Holland Service Manual, P/N 87643846B, covers the B90B, B90BLR, B100B, B100BLR, B110B, and B115B loader backhoes. It is the machine-side service volume for drivetrain, axle, brake, hydraulic, steering, electrical, cab, loader, and backhoe repair.

PDF Search, Electrical Bookmarks, and Page Count

Search and diagram detail: Service text supports PDF search, but labels within many circuit diagrams are not searchable. Embedded bookmarks cover Section 55, Electrical System, rather than the whole manual. Small wiring labels, connector numbers, and wire codes require zooming.

The download is one printable, English-language PDF with 1,110 pages. That total includes 14 opening pages: one cover, three introductory pages, seven contents pages, and three blank or near-blank pages.

Transmission, Hydraulic, and Backhoe Service

The following selected coverage highlights show the main workshop areas. Other topics include loader-bucket self-leveling and temporary wiring-harness repair.

• Transmission service: Turner COM-T4-2025 Powershuttle and Dana T16000 Powershift removal, step-by-step disassembly and assembly, clutch and gear work, shimming, pressure tests, and stall testing.

• Axle repair: Carraro front axles and CNH D46/Carraro rear axles, including wheel hubs, reduction groups, differential and pinion service, bearing setup, and steering-angle checks.

• Hydraulic service: Casappa pump, Rexroth mechanical and pilot control valves, relief valves, swing system, hydraulic control levers, and loader/backhoe cylinder teardown, inspection, and repair.

• Electrical diagnosis: Configuration-specific wiring diagrams, starting and charging tests, speedometer calibration, instrument self-test, onboard error-code retrieval, and steering-control component checks.

• Brakes and steering: Parking-brake adjustment, brake-cylinder service and bleeding, plus power-steering disassembly, assembly, and fault finding for the covered steering configurations.

• Cab heating and air conditioning: HFC-134a system diagnosis, flushing, evacuation, charging, component service, and compressor procedures.

• Loader and backhoe attachments: Loader bucket and frame removal, center-pivot and sideshift backhoe removal, bucket and dipper work, telescopic-dipper service, and stabilizer systems.

Written for skilled service engineers, the manual specifies authorized workshops for maintenance and repair work, with the special equipment required by the procedures.

Configuration Matching and Engine Coverage

The configuration tables distinguish Powershuttle and Powershift drivetrains, 2WD and 4WD, 2WS and 4WS steering, cab and ROPS versions, and mechanical and pilot controls. They also separate sideshift and center-pivot backhoes and short, long, and telescopic dipper arrangements.

Engine identification distinguishes the mechanical F4GE9484C*601 from the electronic F4HE0484G*J102, F4HE9484C*J102, and F4HE9484C*J103 builds. Steering coverage identifies the Danfoss OSPC 125 LS for 2WS and OSPC 160 LS for 4WS.

Separate engine volume: New Holland identifies the complete service documentation as two volumes. This download contains the Loader Backhoe volume; full internal engine repair belongs to the separate Engine Service Manual, Print No. 87659057A, which is not included.

Drivetrain and Axle Repair Depth

The Turner section provides oil-flow and supply diagrams, forward/reverse clutch operation, and separate internal layouts for 2WD and 4WD assemblies. Synchronizers, shafts, clutch packs, and their setup data are treated individually.

Dana coverage adds hydraulic and power-flow diagrams, pressure-check locations, cooler-circuit information, gear-and-clutch layouts, and microprocessor fault-finding material. The torque converters are welded units: their coverage includes cleaning, inspection, removal, installation, and stall testing, rather than internal converter disassembly.

Axle sections distinguish the Carraro 26.00, 26.16, and 26.28 front assemblies, CNH D46 rear axle, and Carraro 26.32M rear axle. Bearing, shim, steering-knuckle, differential, and pinion procedures follow the applicable assembly.

Hydraulic Circuits and Attachment Systems

Separate hydraulic schematics cover 2WS and 4WS machines with sideshift mechanical controls, sideshift pilot controls, or center-pivot pilot controls. Rexroth load-sensing flow-sharing valves, the Glide Ride accumulator, and swing-system oil flow receive their own treatment.

Cylinder procedures cover the loader, bucket, boom, dipper, telescopic dipper, stabilizers, swing, and sideshift lock. The attachment chapters distinguish mechanical and hydraulic backhoe controls and the different loader and backhoe mounting arrangements.

Electrical Tests and Fault Isolation

Electrical diagrams distinguish Powershuttle ROPS and cab machines, Powershift cab machines, and 4WS configurations. Fuse/relay identification, connector views, ground points, battery checks, and switch and sensor tests support circuit tracing; 4WS connector and solenoid-operation views address steering-control faults.

For B100B, B110B, and B115B machines, the diagnostic-display section explains setup functions, warning messages, self-test, and stored error-code retrieval. Powershift LED fault codes and test modes help distinguish electrical control faults from hydraulic or mechanical transmission problems before component teardown.

Special Tools and Repair Cautions

Pinion-depth setup uses the Carraro false pinion 380002219 with false differential box tools 380000407 and 380000440. Transmission tooling includes bearing puller 380002683 and spring compressor 380002689; cylinder-head wrench references include 380000721, 380000724, and 380000725.

Turner case separation can dislodge bearing cones and shims, while the multi-plate 4WD clutch has an orientation-sensitive outer piston seal; incorrect reassembly can disturb bearing setup or clutch sealing. Casappa pump instructions also require bearing blocks to retain their original positions and component pairing.

The manual calls for mechanical support of raised loader/backhoe structures, hydraulic-pressure release, and battery isolation where specified. Air-conditioning work requires suitable HFC-134a recovery and charging equipment.

A Preview of Transmission Test and Axle Setup Data

Turner Powershuttle hydraulic test specifications give a system pressure of 13.7–15.2 bar and torque-converter pressure of 7–11 bar at 2,000 rpm, with transmission oil at 80–85 °C.

The Carraro 26.16 front-axle assembly section specifies pinion-to-ring-gear backlash of 0.18–0.25 mm. Related sections provide component-specific torque tables, fluid capacities, inspection and wear limits, shim and end-float data, and electrical test specifications.
