What makes this JLG 400S & 460SJ Illustrated Parts Manual particularly valuable is its organization by system and its attention to serial number breaks. Each figure is accompanied by a parts list that includes item numbers corresponding to callouts on the illustration, part numbers, quantities, and descriptions. The manual covers the full range of configurations, from 2WD to 4WD, from standard machines to those equipped with the ADE System, and from multiple engine platforms including Caterpillar, Deutz, Ford, GM, and Isuzu.

Serial Number Breaks and Model Variations

The JLG 400S and 460SJ machines were produced across a range of serial numbers, and this manual accounts for the parts changes that occurred throughout production. Serial number breaks are noted throughout the parts lists, with specific ranges indicated for components that changed over time. For example, the manual distinguishes between machines prior to SN 0300067471, SN 0300067471 through 0300072505, and SN 0300072506 through 0300096000 for various frame and axle components. Similar breakpoints exist for the ADE System introduction (SN 0300064404), drive hub assemblies (SN 0300076633), and many other components. Always compare your machine’s serial number against the ranges shown in the manual before ordering parts.

Engine and Powertrain Coverage

The JLG 400S & 460SJ Illustrated Parts Manual covers machines equipped with several engine options. The Caterpillar engine installation section includes detailed parts breakdowns for the engine assembly, cooling system, exhaust, air intake, and associated hardware. The Deutz engine installation covers the F3M2011 and F4M2011 engines, with separate sections for machines before and after SN 0300077682. The Ford engine installation covers the LRG-425 engine in both standard gas and dual fuel configurations, with coverage for Tier I and Tier II engines. The GM engine installation covers the 3.0L engine, and the Isuzu engine installation covers the 4LE1 diesel. Each engine section includes the pumps, generator (if equipped), and all mounting hardware.

Hydraulic and Electrical Systems

The hydraulic diagrams section provides complete schematics for the axle lockout system, 2WD drive system, 4WD drive system, and standard hydraulic system. These diagrams show hose routings, fitting part numbers, valve locations, and component connections. The electrical section includes harness component installations for machines both with and without the ADE System, showing connector part numbers, wire routing, and component locations. These diagrams are invaluable for troubleshooting and for identifying the correct hoses, fittings, and electrical components when replacements are needed.

Platform and Controller Assemblies

The platform section covers both front entry and side entry platforms, including the soft touch installation for each. The platform console assembly is detailed for machines both with and without the ADE System, with parts breakdowns for the console box, switches, relays, controllers, and associated hardware. The controller assemblies for swing/lift and drive/steer functions are shown in both original equipment and service replacement configurations, with detailed parts lists for each.

Cylinder Assemblies

Section 5 provides comprehensive parts breakdowns for every cylinder on the JLG 400S and 460SJ, including the axle lockout cylinder, level (platform slave) cylinder, jib lift cylinder (460SJ), main lift cylinder, master cylinder, steer cylinder, and telescope cylinder. Each cylinder assembly is shown in exploded view with part numbers for the barrel, rod, head, piston, seals, valves, and all internal components. Seal kits are listed separately where applicable, making it easy to order the correct seal kit for a rebuild.

Decals and Special Options

The decal section covers both ANSI spec and country spec decal installations, with part numbers for every safety and informational decal on the machine. The special options section covers the SkyWelder installation, with parts breakdowns for the welder assembly, mounting hardware, and electrical connections. Additional special options are listed with their part numbers for easy reference.

Recommended Service Parts Stock

Section 9 provides a list of recommended service parts to keep in stock for emergency repairs. This section is divided into standard parts (filters, relays, switches, controllers) and variable parts (engine-specific filters and components). This is a practical reference for fleet managers who want to minimize downtime by having commonly needed parts on hand.

Part Number Index

A comprehensive part number index at the back of the manual lists every part number in the book along with the page number(s) where it appears. This makes it easy to look up a specific part number and find all the information about it, including which assembly it belongs to and what other parts are used with it.
