Multiquip 11971725100 Gear Assembly Idle 3TNV76 AR16-2

The Multiquip 11971725100 is a genuine OEM Gear Assembly Idle 3TNV76 AR16-2 designed for the AR16-2 asphalt ride-on roller. As a direct Multiquip OEM component, this idle gear assembly is manufactured to the exact tolerances required by the 3TNV76 engine, ensuring proper meshing, load transfer, and valve timing synchronization. Sourced direct from Multiquip, part 11971725100 is the correct replacement for AR16-2 machines requiring idle gear service or drivetrain restoration.

Key Features

• OEM Gear Precision — Manufactured to exact tooth profile and hardness specifications for the 3TNV76 engine, ensuring smooth gear engagement and correct rotational timing.
• Direct Engine Application — Engineered specifically for the Yanmar 3TNV76 engine platform fitted to the AR16-2 roller, with no adaptation or shimming required for installation.
• AR16-2 Roller Compatibility — Confirmed fitment for the Multiquip AR16-2 asphalt ride-on roller — the right part for the right machine, verified by model code.
• Engine Timing Integrity — A worn or damaged idle gear can disrupt valve and injection timing, leading to rough running, power loss, or engine damage; replacing with this part restores correct operation.
• Genuine Multiquip OEM Quality — Backed by Multiquip's OEM supply chain, this part meets the same material and dimensional standards as the original component installed at the factory.

The idle gear assembly serves as an intermediate gear within the engine's geartrain, transmitting rotational motion between the crankshaft and camshaft to keep valve timing precisely synchronized with piston movement. On the 3TNV76 engine, this component must maintain consistent mesh under load — wear or failure causes timing drift, increased engine noise, and accelerated damage to surrounding geartrain components. Replacing the idle gear assembly at the first sign of wear keeps the engine running cleanly and protects the broader valve and fuel injection system from knock-on damage.
