The Multiquip 50034600 Roll Pin 4 x 18 is a genuine OEM component designed for use across multiple Multiquip equipment families, including MVH502DSB and MVH502DSB2 reversible plate compactors, MQ41TDH trash pumps, and MDR-9D power trowels. As an authorized OEM part, the part is manufactured to the same specifications as the original hardware installed at the factory, ensuring a correct, secure fit every time. DHS Equipment sources this roll pin directly through official Multiquip channels, so you can order with confidence knowing you are getting the right part for your machine.
Key Features
- Genuine OEM Construction — Manufactured to exact Multiquip tolerances, delivering the precise dimensional fit and shear strength that this roll pin position demands in service.
- Direct Drop-In Replacement — the part installs into the original bore without reworking, machining, or modifying the host component.
- Broad Equipment Compatibility — Confirmed fitment for MVH502DSB, MVH502DSB2, MQ41TDH, and MDR-9D machines, covering reversible plate compactors, trash pumps, and power trowels in a single part number.
- Maintains Mechanical Alignment — A correctly seated roll pin locks rotating and reciprocating components in proper alignment; a worn or missing pin allows unwanted movement that accelerates wear on surrounding parts.
- Hardened Spring Steel Construction — Roll pins rely on radial tension to grip the bore securely; OEM-spec material hardness ensures the pin compresses and expands correctly without cracking or backing out under vibration.
A roll pin — also called a spring pin or slotted pin — is a hollow, slotted cylindrical fastener that holds shafts, gears, levers, and linkage components in a fixed rotational or axial position. It works by compressing slightly as it is driven into a drilled hole, then expanding against the bore wall to create a friction-lock. This means no threads, no adhesives, and no retaining clips are needed for the joint to hold. When a roll pin shears, backs out, or corrodes, the components it was locating can shift, slip, or separate entirely — causing accelerated wear, misalignment, or sudden mechanical failure that takes the machine out of service until the pin is replaced.
