The scope of this JLG 1200SJP 1350SJP illustrated parts manual is enormous. Every major assembly is broken down into exploded illustrations with itemized part numbers, revision letters, and quantities. Serial number breaks are noted throughout, so whether you are working on an early 1200SJP built before S/N 79596 or a late-production 1350SJP, you can see exactly which hub assembly, valve, or cylinder applies. The parts index at the back lets you search by part number and jump straight to the figure that uses it.

What This Parts Manual Covers in Detail

The frame section alone spans axle installations for both fixed and oscillating axles, showing stop bars, wear pads, shims, pins, and mounting hardware with all the serial-number variations. The drive hub and motor assemblies are covered in three separate breakdowns depending on serial number, with individual kits for brake discs, brake seals, bearings, planet gears, and mechanical disconnect components. If you are rebuilding a traction motor or chasing a hub leak, the exploded views here are essential.

On the turntable, the JLG 1200SJP 1350SJP parts catalog documents the main valve assembly, swing motor/hub, Deutz diesel engine installation, hydraulic pump assembly, both generator options, fuel and hydraulic tank installations, rotary coupling, and ground control box. The pump section breaks down the front drive pump, middle drive pump, and rear function pump with rotary groups, control groups, port plates, and internal gear pump components. The swing motor/hub assembly includes the brake assembly with friction discs, springs, seals, and bearings called out individually.

The boom section covers the base, mid, and fly sections with wear pads, sheaves, cables, pins, and shims. Power track components are itemized for both 1200SJP and 1350SJP, along with the carrier assemblies and link kits. Boom sensors and switches are listed with their serial number ranges, including the boom length sensor, angle indicator, jib limit switch, and cable break proximity switch.

Cylinder assemblies are fully illustrated with seal kits, pistons, rods, heads, cartridges, and holding valves. The steer cylinder is shown in two versions depending on serial number. The lift cylinder, level cylinder, jib cylinder, telescope cylinder, axle extension cylinder, and axle lockout cylinder all have their own exploded views with seal kit part numbers.

Hydraulic diagrams are provided for the drive circuit, oscillating axle, steer circuit, turntable, boom, and 7500W generator. Each diagram includes a parts list of hoses, fittings, tees, and adapters with part numbers. The electrical section covers schematics for machines prior to S/N 87579 and from S/N 87579 to present, plus harness component installations with connector part numbers, sockets, pins, seals, and cable assemblies.

Who This Manual Is For

This JLG 1200SJP 1350SJP parts manual PDF is built for equipment owners, fleet maintenance managers, field service technicians, and parts departments that need to identify and order components accurately. Because JLG used running serial number changes throughout production, having the correct manual with all the break points is the difference between ordering the right part and returning the wrong one. The exploded views show how components assemble, which helps during teardown and reassembly even when you already have the replacement part on the bench.

Why the Right Parts Manual Matters

Boom lift repairs are expensive, and downtime is worse. Ordering a hub seal kit for a pre-S/N 79596 machine when you actually have a S/N 83552 unit wastes days. This manual removes that guesswork by listing every serial-number-specific variation side by side. The part number index at the back of the JLG 1200SJP 1350SJP Illustrated Parts Manual lets you verify a part number against multiple figures before you commit to an order. Torque values and assembly notes may appear in the service manual, but the parts breakdown is where you confirm what actually goes inside the assembly.
