The Multiquip 11971725050 is a genuine OEM Shaft Idle Gear 3TNV76 AR16-2 designed for the AR16-2 ride-on asphalt roller. Sourced directly from Multiquip, this part meets the original engineering specifications for the 3TNV76 engine used in AR16-2 equipment. Keeping the correct idle gear shaft in service ensures the engine's gear train operates with the proper mesh and timing. DHS Equipment stocks this genuine OEM component so you can get your roller back to work without compromise.
Key Features
- Genuine OEM Gear Metallurgy — Manufactured to the exact material hardness and tooth profile specified for the 3TNV76 engine, maintaining correct gear mesh load capacity.
- Direct Drop-In Installation — Machined to OEM shaft diameter and gear dimensions, so it seats and aligns in the idle gear carrier without additional fitting or modification.
- Confirmed AR16-2 Fitment — Verified for the Multiquip AR16-2 ride-on asphalt roller equipped with the Yanmar 3TNV76 engine platform.
- Engine Timing Integrity — A correctly dimensioned idle gear shaft maintains proper rotational transfer between the crankshaft and camshaft gear sets, protecting valve timing and injection timing accuracy.
- Wear-Resistance for Sustained Load — Idle gear shafts in diesel engines run under continuous oil-film load; an OEM-spec part resists premature wear that can introduce gear lash and engine noise over time.
The idle gear shaft is a critical component within the engine's geartrain, serving as the pivot and bearing surface for the idle gear that transfers rotational force between the crankshaft gear and the camshaft gear. In a 3TNV76 Yanmar diesel engine, this shaft must maintain precise dimensional tolerances to keep gear engagement smooth and ensure correct valve and injection timing are preserved throughout the engine's operating life. When the idle gear shaft wears or fails, it can allow excessive gear lash, introduce noise and vibration into the drivetrain, and ultimately cause timing drift that leads to poor performance or internal engine damage.
