Using the exact specified hardware maintains structural integrity across all supported assemblies.
Key Features
- Correct Thread and Length Specification — 3/8 x 1-3/4 in. dimensions match the original fastener spec exactly, so the bolt seats and torques correctly without shimming or modification.
- Genuine OEM Hardware — Supplied through Multiquip's authorized OEM parts chain, confirming correct grade, thread pitch, and head type for the intended application.
- Wide Cross-Equipment Compatibility — A single part number covers concrete pumps (LS300, LS600, C30 series), Whiteman and Essick mixers (WM and EM series), MQ mixers (MC series), and walk-behind rollers (V304, V305, AR14H, R2000H).
- Structural Integrity Under Load — Properly torqued to spec, this bolt secures critical assemblies on mixing, pumping, and compaction equipment that operate under sustained mechanical stress.
- Direct-Fit Replacement — Drops into the same bolt hole pattern as the original, so installation follows the standard service procedure for each supported model.
A bolt of this specification serves as a primary structural fastener across multiple component assemblies — securing housings, frames, guards, and mechanical subassemblies that experience continuous vibration and load cycling during operation. When a fastener of the wrong grade, thread pitch, or length is substituted, it can back out under vibration, strip its mating threads, or fail to achieve correct clamping force, potentially allowing assembled components to shift or separate. Using the correct OEM-specified bolt — part number 492378 — ensures the joint behaves as the original design intended and that torque values from the service manual can be applied with confidence.
