Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original material and dimensional spec, ensuring the pin seats correctly in its bore without play or misalignment.
- Direct Drop-In Replacement — Matches the original EM308 hinge pin profile for straightforward installation with standard hand tools.
- Broad Fitment Coverage — Compatible with WM120SH, WM120PH, EM120S Series, EM120P Series, HTN27K, HTN28K, HHN31V, HHN34TVD, JWN24HTCSL/HSCSL, HTN series, and JTO Series equipment.
- Pivot Integrity Under Load — A correctly fitted hinge pin keeps hinged doors, frames, or covers operating smoothly; a worn or missing pin can cause misalignment, excessive wear on surrounding components, and unsafe movement of heavy assemblies.
- Structural Safety Relevance — On mixer drum doors and trowel guard assemblies, a secure hinge pin is essential to preventing unintended opening or movement during operation.
A hinge pin acts as the central pivot point for any hinged assembly on the machine — whether that is a mixer drum door, an access panel, or a guard cover. It holds two mating components in rotational alignment while allowing controlled movement along a single axis. When a hinge pin wears, bends, or goes missing, the hinged assembly loses support, creating slop in the joint that accelerates wear on surrounding hardware and can compromise operator safety. Replacing a worn hinge pin promptly with the correct OEM part restores proper alignment and keeps the assembly operating as intended.
