Key Features
- OEM-Grade Fastener Specification — Manufactured to the exact thread pitch, length, and tensile rating of the original 5X95 stud bolt used in GX100U-KRBF engine applications, ensuring proper clamp load and torque retention.
- Drop-In Engine Hardware Replacement — Matches the original stud configuration for straightforward installation without reworking mounting surfaces or hardware.
- Confirmed Fitment for MTX Rammers — Verified for the MTX50HD, MTX60HD, MTX70HD, MTX60HF, and MTX70HF rammer models.
- Maintains Engine Mounting Integrity — A worn, stripped, or broken stud bolt can compromise engine stability under the repeated impact loads that define rammer operation; replacing it promptly preserves frame and engine alignment.
- Genuine Multiquip OEM Part — Supplied as an authorized OEM component under part number 90042Z4ES30, carrying the same quality traceability as original production hardware.
A stud bolt serves as a threaded fastener that anchors a component — in this case, engine-related hardware on the GX100U-KRBF — securely to its mounting surface. Unlike a standard bolt, a stud remains fixed in the base material while a nut is threaded onto the exposed end, providing consistent clamping force across repeated assembly cycles. On a rammer, which generates continuous vertical impact force during operation, stud bolts are subjected to significant vibration and stress. A damaged or missing stud allows mounting points to loosen, which can lead to misalignment, accelerated wear on adjacent components, and potential engine damage if left unaddressed.
