This illustrated parts manual goes far beyond a simple parts list. Each section provides exploded-view illustrations with item numbers that correspond directly to detailed part number tables. The brake actuator assemblies section, for example, breaks down every component of the Model 91, DA10, and DA20 actuators, from wear pads and dampers to master cylinder repair kits. The motor/pump/tank assembly section gives you a complete breakdown of the hydraulic power unit, including the pump, solenoid, reservoir, and all internal seals. The suspension sections are split by serial number range, ensuring you order the correct leaf spring, shackle, or axle welldent for your specific trailer. The enclosure sections for the EC10, EC12, and EC14 models are similarly divided by serial number, with separate coverage for units built before and after S/N 0050002838. The part number index at the end of the manual lets you look up any part number and immediately find the page where it appears.

What This Manual Enables You to Do

With the JLG Triple-L Trailers Illustrated Parts Manual, you can confidently identify and order replacement parts for virtually every system on your trailer. The exploded views make it easy to see how components assemble and disassemble, which is invaluable when you are repairing a brake actuator, replacing a hydraulic cylinder, servicing the motor/pump/tank unit, or rebuilding a suspension. The part number tables include quantities, descriptions, and revision notes, so you know exactly what you are getting and whether a part has been superseded by a newer number. For models like the 7610, 7612, 7614, and 7616, the manual covers both single and tandem axle configurations, and for the UT series, it includes optional rail and tailgate installations. The electrical schematic section provides wiring diagrams for the 4-terminal, 6-terminal, and 7-terminal connectors, helping you troubleshoot lighting and brake wiring with confidence. The decal installation section ensures you can replace worn or damaged safety and informational decals with the correct part numbers.

Why This Manual Matters

Using the correct part numbers and following the proper assembly procedures is critical for the safe and reliable operation of your JLG Triple-L trailer. This manual eliminates guesswork by providing the exact part numbers and quantities needed for each assembly. Whether you are a professional technician, a fleet maintenance manager, or a trailer owner performing your own repairs, having the illustrated parts manual on hand saves time and prevents costly ordering mistakes. The serial number breakpoints throughout the manual are especially important, as they ensure you order parts that are compatible with your specific trailer’s production run.
