The Multiquip 90018ZJ1840 is a genuine OEM Bolt Stud 8 X 22 Gx610 designed for GA9.7HE gasoline-powered generators and AR13HA/HAR, AR13HC, and AR13H asphalt ride-on rollers. As a direct Multiquip OEM component, this stud bolt is manufactured to the exact dimensions and thread specification required by the GX610 engine used across these machine families. Sourcing the correct OEM fastener ensures proper clamping load and joint integrity — critical on engine-mounted hardware that operates under sustained vibration and heat cycles. Verify your model code against the fitment list before ordering to confirm compatibility.
Key Features
- OEM Thread and Dimensional Accuracy — Produced to the exact M8 x 22 mm specification of the GX610 engine application, ensuring correct thread engagement and torque capacity without risk of cross-threading or under-clamping.
- Direct Engine Application Fit — Engineered specifically for GX610 engine configurations, so installation aligns with existing mounting points and hardware without modification to surrounding components.
- Broad Multiquip Fitment — Compatible with GA9.7HE generators and AR13HA/HAR, AR13HC, and AR13H ride-on asphalt rollers, covering multiple machine families from a single part number.
- Vibration-Resistant Fastening — A properly spec'd stud bolt maintains consistent clamping force across thermal expansion and engine vibration cycles, preventing joint loosening that can lead to component damage or misalignment.
- Fastener Integrity for Critical Engine Joints — Using the correct OEM stud in fuel system, exhaust, or structural engine mounts prevents the safety risks associated with fastener failure under load — particularly relevant on rollers and generators operating in continuous-duty applications.
A stud bolt is a fully threaded or partially threaded fastener used to secure engine components, covers, or structural assemblies by threading into a tapped bore on one end and accepting a nut on the other. On GX610-equipped machines, stud bolts are commonly used at exhaust flanges, engine mounts, and accessory brackets where a through-bolt configuration is not practical. When a stud becomes worn, stretched, or cross-threaded, it compromises the clamping load of the joint — which can result in gasket failure, exhaust leaks, or component separation during operation. Replacing a damaged stud with the correct OEM part restores the joint to its original design specification.
