The Multiquip 510717 Bolt 1/2 x 1-3/4 In. is a genuine OEM fastener designed for a broad range of Multiquip concrete pump, power buggy, and roller equipment. This bolt services hydraulic-driven concrete pump models including the LS400, LS40D, LS40TD, LS500, LS50TD, LS600, and LS60TD, as well as Whiteman hydraulic power buggies in the WBH-16 and WBH-21 series, and the AR14H asphalt ride-on roller. Sourcing the correct OEM-spec fastener ensures proper clamping load and long-term joint integrity across the assemblies it secures.
Key Features
- Correct OEM Thread and Shank Specification — Manufactured to the exact 1/2 in. diameter and 1-3/4 in. length called out in the Multiquip parts documentation, ensuring proper torque retention in the joint.
- Direct-Fit Replacement — Installs directly into existing threaded bores and mounting points without rework, maintaining the original bolt pattern and clamp load.
- Wide Equipment Compatibility — Fits Multiquip concrete pump models LS400, LS40D, LS40TD, LS500, LS50TD, LS600, and LS60TD; Whiteman power buggies WBH-16 and WBH-21 series; and the AR14H ride-on roller.
- Structural Joint Integrity — A correctly torqued fastener of the right spec prevents loosening under vibration and load cycling — protecting the assemblies and components it secures from accelerated wear or misalignment.
- Genuine OEM Sourcing — Supplied as an authentic Multiquip part, meeting the material grade and dimensional standards of the original hardware used in production.
A bolt of this size and grade serves as a primary fastener in structural and mechanical assemblies across construction equipment, securing components such as housings, brackets, drive assemblies, and mounting plates. When a fastener is the wrong length or diameter, it can fail to develop full clamping force, leading to joint movement, fretting, and eventual component failure. Using the correct OEM replacement — part number 510717 — ensures the fastener engages the full thread depth, withstands operational vibration, and holds the assembly within specification for the service life of the equipment.
