New Holland BB9040 Big Square Baler Repair Manual 87491714 – Full PDF Workshop Guide

Description

Written specifically for the BB9040 big square baler, this New Holland BB9040 Repair Manual (publication number 87491714, dated 23/09/2008) is a full workshop-level PDF covering disassembly, overhaul, adjustment and reassembly of the machine’s major systems. It is organised by function – distribution systems, power production, power train, travelling, frame positioning and crop processing – so a chapter is easy to find whether you are chasing a wiring fault, rebuilding the main gearbox or re-timing the knotters.

Each service chapter follows the same internal logic: functional data first explaining how the assembly works, then remove, disassemble, inspect, assemble, install and adjust operations in working order. That structure is what turns this BB9040 repair manual into a genuine bench document rather than a pile of general advice.

What This New Holland BB9040 Manual Lets You Do

The manual is written around real repair sequences. You can read the dynamic description of the main gearbox, follow the teardown in the correct order, then use the adjustment chapter to bring crown wheel backlash, intermediate shaft pre-load and plunger crankshaft pre-load back to specification. Every major assembly on the baler is treated the same way.

Main Drive, PTO and Gearbox Overhaul

The Power Train section covers the primary process drive in depth. Flywheel removal includes the torque values for the brake bolt hub and the retaining bolt plus the flywheel axial play figure. The torque limiter chapter covers the flywheel slip clutch internals – Belleville washers, friction discs, straight plates, pawl and spring assembly – with a detailed exploded view. The PTO shaft chapters cover the 80 degree CV joint and the standard U-joint through disassembly, inspection and assembly, including retaining ring and bearing cup handling, plus quick-connect lock service. Gearbox coverage includes removal, complete disassembly, shaft-by-shaft assembly of the input shaft, intermediate shaft and plunger crank drive shaft, and the adjustment chapter for crown gear/pinion backlash and bearing pre-load.

Picking Up, Feeding and Pressing

The Crop Processing chapters cover the complete crop path. Picking up covers pickup removal and installation, pivot plate bearings, the reel shaft overhaul, tine and guard replacement, auger drive removal and installation, gauge wheel rebuild and the reel drive slip clutch, which is factory set at 1000 Nm. Feeding covers the precompression drive and slip clutch, the lower drive sprocket, the packer shaft with its centring measurements, packer forks and connecting rods, and the stuffer – including stuffer timing measured from the tines to the stationary knife, connecting rod replacement and top and bottom plate renewal. Square bale pressing covers the density system, density cylinders, hydraulic pump, plunger removal and inspection, plunger knives and clearance setting, plunger connecting rods, hay dogs and the load sensing system with its pre-load adjustment procedure.

Knotters, Needles and Twine Tying

The twine tying chapter is the most detailed in the manual. It covers knotter drive removal and installation, knotter brake, the knotter fans, twine routing, the length control system, needle removal, installation and adjustment, and full knotter system removal, assembly, installation, adjustment and repair. The knotter service limits give exact cam gear spacing and the shim placement needed to reach it, along with the billhook, knife arm, twine disc and twine finger adjustment values.

Electrical, Electronic and Density Systems

The Distribution Systems chapter includes the complete electrical schematic set: the density system (load sensor B17 and density valve Y2), the InfoView monitor circuit, bale count and mistie, and road lights, plus connector pin-outs for the monitor connectors, the trailer socket, the load sensor and the density valve. The electronic system chapter includes the InfoView monitor service instruction, EPROM replacement and a monitor troubleshooting table covering LOAD signal faults, bale count flickering with and without broken twine, ELEC and SenS error messages and a dead monitor. The density system has its own troubleshooting table for no-pressure and auto-density faults.

Brakes, Axle, Wheels and Towing

Travelling covers the single axle, the mechanical parking brake linkage, the hydraulic pulled-type vehicle brake including command cylinder, hydraulic lines, brake shoes and control shaft, the pneumatic pulled-type brake with control valve overhaul and pneumatic accumulator, and wheel removal and installation with bearing and hub service. The Frame Positioning chapter covers front towing hitch removal and installation, plus the correct routing of the electrical looms, hydraulic hoses and pneumatic lines through the drawbar, including the yellow and red pneumatic coupling positions on the brake valve.

Reference Data and General Instructions

Torque tables are supplied for both imperial and metric hardware across SAE grades 2, 5 and 8 and metric classes 5.8, 8.8 and 10.9, together with bolt tightening sequences for flange patterns. General instructions cover shimming, rotating shaft seal installation, O-ring seals, sealing compounds, cotter pins and spare parts identification. General specification tables list overall dimensions, weights, axle and tyre data, pick-up, feeder, precompression, bale chamber, tying mechanism and main drive figures, plus the tractor requirements for running the baler. A consumables table lists the correct lubricants and service intervals.

Who This New Holland BB9040 Repair Manual Suits

This is a working document for anyone who maintains, repairs or rebuilds a BB9040. It suits an experienced mechanic who wants the manufacturer’s own procedures and service limits in front of them, an operator who does their own maintenance and wants to understand how the density, tying and feeding systems actually work, and a workshop that needs a single reference covering the mechanical, hydraulic and electrical sides of the machine. It is also useful when ordering parts, since the product identification section explains how the model, serial number and year of manufacture are stamped and how to read them.

Get the New Holland BB9040 Repair Manual as an Instant PDF

With this BB9040 repair manual on hand you can strip and rebuild the main gearbox, replace a failed packer fork, re-time the stuffer, adjust knotter cam gear spacing, chase an electrical fault through the wiring schematics, or set the plunger knife clearance – all from one document instead of guesswork. Correct procedures, specified torques and real service limits mean fewer damaged parts, less downtime and a baler that runs to specification rather than near enough.
