The Multiquip 551438680 is a genuine OEM MRX-440P Cylinder Pin designed for the MRX-440P walk-behind roller. Sourced directly from Multiquip, this pin is manufactured to the same specifications as the original component installed at the factory. Verified fitment for the MRX-440P ensures you get a part that drops into place without guesswork or modification.
Key Features
- Genuine OEM Construction — Manufactured to exact dimensional tolerances required by the MRX-440P cylinder assembly, maintaining the integrity of the pivot or linkage connection.
- Direct-Fit Replacement — Engineered to align with the original bore and retaining points on the MRX-440P, so installation follows the same procedure as the factory-fit component.
- Confirmed MRX-440P Compatibility — Part number 551438680 is specific to the MRX-440P walk-behind roller, eliminating the risk of ordering a mismatched pin diameter or length.
- Cylinder Integrity Preserved — A properly fitted cylinder pin maintains correct articulation or actuation in the roller's hydraulic or mechanical cylinder circuit, preventing play, misalignment, or accelerated bore wear.
- Durable Load-Bearing Design — Cylinder pins are subject to continuous shear and compressive forces during operation; this genuine OEM part is made from material grade suited to those cyclic loads on a vibratory walk-behind roller.
A cylinder pin serves as the structural pivot or retaining link between a cylinder and its mounting points, allowing controlled movement or force transfer within the machine's cylinder assembly. When a cylinder pin wears, bends, or fails, the cylinder can lose its alignment, introduce unwanted play into the linkage, or become unable to transfer force effectively — leading to imprecise operation and potential damage to surrounding components. Replacing a worn pin promptly with the correct OEM part restores the cylinder's ability to function as intended and protects the mating bores from further damage.
