Description
JLG G6-42A Telehandler Illustrated Parts Manual 91474001 PDF
This JLG G6-42A Telehandler Illustrated Parts Manual 91474001 PDF is an extensive parts reference for the G6-42A telehandler. The manual is organized around illustrated assemblies and matching parts lists, allowing components to be traced from the machine frame and boom through the drivetrain, hydraulics, electrical equipment, cab and numerous attachments and options. Its coverage is highly serial-number specific, with many assemblies divided into earlier and later configurations so the correct part arrangement can be identified for the machine being serviced.
With 848 PDF pages, this manual goes far beyond a simple replacement-parts list. Exploded and assembly illustrations are paired with item numbers, part numbers, quantities, descriptions and revision information. Many entries also identify replacement or superseded parts, applicable serial ranges, optional configurations, kits, seal kits and related assemblies. The final pages include recommended spare parts and a large part-number index for locating referenced components throughout the manual.

Serial Number Coverage
The JLG G6-42A illustrated parts manual identifies its principal machine coverage as SN 0190001 through 0190457 and SN 0160000022 through 0160048656. Individual figures frequently narrow the applicability further. These serial breaks are especially important because the manual shows changes in frame components, boom parts, attachments, engines, transmissions, axles, controls, hydraulic components, electrical harnesses and optional equipment as production configurations changed.
For example, separate illustrations are provided for early and later frame shrouding, axle installations, quick-switch assemblies, attachment configurations, engine installations and numerous hydraulic and electrical components. This makes document 91474001 useful when the same G6-42A component area has more than one production version.
Illustrated Parts and Assembly Reference
The manual uses detailed illustrated views to connect physical components with their corresponding parts listings. Assemblies such as the boom sections, carriage equipment, axles, transmissions, hydraulic cylinders and engine installations are broken down into serviceable items. Parts tables identify the illustrated item number together with the applicable part number, quantity and description. Where applicable, the listings also call out items that are no longer available, replacement part numbers, component kits and references to another section for a deeper breakdown.
IMAGES PREVIEW
This is particularly useful for complex assemblies where ordering by appearance alone can be unreliable. The JLG G6-42A parts manual lets the user follow the illustrated assembly, check the serial-number note and then locate the corresponding part listing. Numerous figures also contain fitting, hardware and torque information relevant to the assembly shown.
Engine, Transmission and Drivetrain Variations
The engine and attaching-parts section covers multiple powertrain configurations used in the G6-42A. The manual contains separate illustrated material for John Deere engines, a Perkins engine installation and later Cummins engine configurations. John Deere and Cummins listings in the manual include 99HP configurations, while the Perkins installation is identified by its applicable serial range. Related fuel tank and line arrangements, radiator assemblies, air-cleaner installations and exhaust installations are also divided by engine and serial applicability.
Transmission coverage is similarly detailed. Dana transmission material includes the converter housing, case and plate group, torque converter, gear groups, pump drive, charging pump, reverse idler, forward and reverse shafts, first through third shaft groups, output shaft, electric controls, drive plate and drop box. The later-production coverage also includes ZF transmission installation and assembly views covering the torque converter and input, gearbox housing, forward and reverse gear groups, first through fourth shafts, power take-off, control unit and pressure regulator, gearshift system, oil pump and filter, and transfer box.
The drive train section continues with both Carraro and Dana axle configurations. Front and rear axle assemblies are broken down into housings, steering components, gears, differentials, double joints, brakes, wheel hubs and reduction gears. Drive shaft assemblies plus tires and rims are also included.

Taken together, these chapters provide a machine-wide illustrated parts reference rather than coverage of only one subsystem. The user can move from the main structure and boom into attachment hardware, powertrain configurations, axle assemblies, operator-station parts, hydraulic circuits and individual hydraulic components, then continue into electrical equipment and optional packages. The extensive part-number index at the rear provides another route for tracing a known number back to its location in the manual.
Attachments and Optional Equipment
A major strength of the JLG G6-42A Telehandler Illustrated Parts Manual 91474001 PDF is the breadth of attachment coverage. The manual illustrates several carriage configurations as well as buckets, forks, grapple equipment, lifting hooks, truss booms, winch arrangements, material-handling platforms, dual fork positioning equipment and mast assemblies. Earlier and later attachment designs are separated where the production serial break requires it.
The options section adds further detail for equipment that may not appear on every machine. It covers turbo-related components, enclosed and open cab heater arrangements, engine heaters, work-light packages, cold-start equipment, stabilizers, auxiliary boom and hydraulic assemblies, auxiliary electrical systems, beacon lights, remote oil-filter arrangements, truss-boom winch components, seat configurations, road lights, glass shields, air-conditioning arrangements for the different engine installations, and Arctic packages.
Recommended Spare Parts and Part Number Index
Near the end of the manual, JLG provides a recommended spare-parts section intended to identify field-replaceable stock for fleets. It includes items associated with the boom, engine configurations, drive train, hydraulic systems, electrical equipment and miscellaneous machine items. Examples include filter kits, belts, cylinder seal kits, hydraulic filters, electrical senders and switches, starters, alternators and selected axle-related service parts. Special tools associated with Carraro axles, Dana axles and the Dana transmission are also referenced.
The part-number index begins after the recommended-spares section and links individual part numbers back to pages where they appear. For anyone starting with an existing JLG number rather than an assembly location, this index can significantly simplify navigation through such a large parts manual.
Identify the Correct G6-42A Parts Before Ordering
The JLG G6-42A Telehandler Illustrated Parts Manual 91474001 PDF is designed to support accurate component identification across the machine’s frame, boom, attachments, engines, transmissions, axles, cab, controls, hydraulics, electrical system and options. Exploded illustrations, item references, part numbers, quantities and detailed serial-number breaks help you compare the actual machine configuration with the correct parts arrangement before ordering or planning service work.
That detail matters on a G6-42A because many assemblies changed across production ranges and the manual documents those differences directly. Using the appropriate illustration and serial-specific listing helps reduce the risk of selecting a component from the wrong configuration and provides a practical reference when inspecting or dismantling an assembly.
After purchase, the manual is supplied as an instant PDF download. There is no physical book and no shipping delay. You can open the PDF on a computer, tablet or compatible mobile device and print the pages or sections you need for workshop or parts-counter reference.
