The Multiquip 12100 Connection Rod Assembly is a genuine OEM component designed for C30HDN and C30HDNI series concrete pumps and HTN28K, HTN27K, and HTNS5S-2 ride-on power trowels. As a direct OEM replacement, this assembly is built to the same specifications as the original part, ensuring correct fit and function across all compatible equipment. Verify your model code against the fitment list to confirm compatibility before ordering.
Key Features
- Genuine OEM Construction — Manufactured to the same tolerances and material grades as the original, ensuring the rod operates under load without flex, fatigue, or dimensional mismatch.
- Drop-In Replacement — Connects directly to existing mounting points on compatible machines, matching original pin diameter, bore spacing, and overall rod length for straightforward installation.
- Broad Fitment Coverage — Compatible with C30HDN, C30HDNI, HTN28K, HTN27K, and HTNS5S-2 models, covering both concrete pump and ride-on power trowel applications in the Multiquip lineup.
- Sustained Power Transfer — A sound connection rod delivers consistent, uninterrupted motion transfer between the drive mechanism and working components; a worn or cracked rod introduces vibration, misalignment, and accelerated wear on surrounding components.
- Operational Safety — A failed connection rod can cause sudden loss of mechanical drive in both pumping and troweling applications, making timely replacement critical to safe machine operation.
The connection rod assembly transfers mechanical force between the crankshaft or drive mechanism and the reciprocating or rotating components of the machine. In concrete pumps, it converts rotary engine power into the linear piston strokes that move concrete through the discharge system. In ride-on power trowels, it plays a role in drive transmission, linking engine output to the blade or wheel mechanism. When a connection rod wears, bends, or fractures, the machine loses its ability to transmit power cleanly, resulting in erratic performance, increased stress on bearings and seals, and potential sudden mechanical failure.
