The Multiquip 11971721650 is a genuine OEM V-Pulley Crankshaft 3TNV76 AR16-2 designed for the AR16-2 asphalt ride-on roller. This is a direct OEM replacement sourced through the Multiquip parts program, ensuring the component matches the original engineering specifications of the 3TNV76 engine installed in the AR16-2. Verified fitment for AR16-2 machines means you can order with confidence knowing this pulley will seat and align correctly on the crankshaft nose. DHS Equipment stocks genuine Multiquip OEM parts so your roller stays productive without unnecessary delays.
Key Features
- Genuine OEM Crankshaft Pulley — Manufactured to the same tolerances and material grade as the original 3TNV76 engine pulley, ensuring correct belt engagement and load transfer.
- Direct Crankshaft Mount — Engineered to install directly onto the 3TNV76 crankshaft nose of the AR16-2 with correct bore sizing and keyway alignment, eliminating guesswork at installation.
- Confirmed AR16-2 Fitment — Specifically validated for the Multiquip AR16-2 asphalt ride-on roller; use part number 11971721650 to cross-reference against your machine's parts manual.
- Sustained Belt Drive Performance — A correctly sized V-pulley maintains proper belt tension and groove contact, supporting consistent power delivery to driven accessories throughout the roller's operating cycle.
- Wear-Resistant Pulley Profile — The V-groove profile is machined to resist belt slippage and premature groove wear, extending belt and pulley service life under continuous compaction workloads.
The crankshaft V-pulley is mounted directly to the front of the engine crankshaft and serves as the primary drive interface between the engine and belt-driven components such as the alternator or auxiliary systems. It transfers rotational energy from the crankshaft to the belt, making groove geometry and concentricity critical — a worn or damaged pulley causes belt slippage, accelerated belt wear, and potential loss of charging or auxiliary function. Replacing a failed or grooved-out pulley with a genuine OEM part like the Multiquip 11971721650 restores correct belt tracking and protects downstream components from the stress caused by an out-of-spec drive surface.
