The Multiquip 16628 is a genuine OEM Shoulder Bolt 3/4 x 2-1/4 Plt designed for GA9.7HE gasoline-powered generators and AR13H, AR13HA/HAR, AR13HC asphalt ride-on rollers, as well as V304EH, V304ER, and V304EY walk-behind vibratory rollers. As a factory-authorized component, part 16628 is manufactured to the exact dimensions and material grade specified by Multiquip, ensuring a correct drop-in installation without guesswork or fitment issues. This shoulder bolt ships directly from DHS Equipment's inventory, so you can get your machine back to work without extended lead times. Verify your model against the fitment list above before ordering to confirm compatibility.
Key Features
- Precise OEM Dimensional Tolerancing — Manufactured to exact shoulder diameter and length specifications (3/4 x 2-1/4), ensuring consistent clamping load and proper mechanical engagement at the fastener seat.
- Plated Finish for Corrosion Resistance — The Plt (plated) surface treatment resists rust and oxidation in outdoor and wet operating environments typical of roller and generator applications.
- Direct OEM Replacement — Part 16628 installs directly into the designed fastener location; the machined shoulder controls component spacing and alignment without requiring additional shims or hardware.
- Broad Model Compatibility — Fits GA9.7HE generators, AR13H / AR13HA/HAR / AR13HC ride-on rollers, and V304EH / V304ER / V304EY walk-behind rollers, covering multiple Multiquip equipment families with a single part number.
- Structural Integrity Under Load — A correctly installed shoulder bolt maintains precise pivot or bearing-surface alignment; a worn or missing bolt can cause component misalignment, accelerated wear on mating parts, and structural looseness during operation.
A shoulder bolt differs from a standard threaded fastener in that it has a precision-ground unthreaded shank — the "shoulder" — that acts as a locating pin, pivot point, or bearing surface rather than simply clamping two parts together. The shoulder controls the exact spacing and alignment between mating components, which is critical in articulating linkages, roller assemblies, and mounting brackets where consistent geometry directly affects machine performance. When a shoulder bolt is worn, bent, or undersized, the resulting play in the joint can cause premature wear of surrounding components, vibration, and loss of mechanical control in the affected assembly.
