Getting Started Pierce Hefty Hoist Instructions Sometimes you need more than an installation guide to show you how the install is done. We hope our four part guide on YouTube will help answer many of your questions. If you need extra assistance or just have a question feel free to call us at 800-658-6301. The Pierce dump kit is a powerful machine and must be used with extreme care. Deviating from the manual’s instructions may cause personal injury.
Before beginning . . . To reach maximum kit capacity and lift a few questions must be asked. 1. What is the bed length? 2. How much overhang past the frame can I have? 3. What is the optimal dump angle for my application? Desired bed height and lift capacity are determined by the placement of the crossmember. Chassis construction may dictate crossmember location. CHOOSING THE LIFT ANGLE OVERHANG The bed length and overhang length effect the capacity of your kit.

Installation Instructions 1. REMOVE WIRING AND ATTACHMENTS • Remove all attachments holding the sill and bed to the truck frame including electrical wiring, fuel, hydraulic or air lines. • All wires must be supported by the truck frame. 2. CHASSIS SHORTENING & REAR HINGE PLACEMENT • Shorten the chassis in order to create as much overhang as possible. The more overhang past the hinges, gives a counter lever effect and makes, in essence, the dump kit stronger.
. SILL SUPPORT INSTALLATION • Sill supports slip into the scissor assembly tubing and support the truck bed. Sill support bolt location is determined by the bed’s sill construction (fig. 6). Modification may be required. Examples include: A. Notching - the bed crossmembers may interfere with the kit. B. Cutting - if bed height is an issue, cut the sill support to fit within the sill. Hydraulic Connections NOTE: Do not weld the sill supports to the sill. 7.
