Multiquip 11981002940 Thrust Bearing .25OS 3TNV76 AR16-2

The Multiquip 11981002940 Thrust Bearing.25OS 3TNV76 AR16-2 is a genuine OEM thrust bearing designed for the AR16-2 asphalt ride-on roller. This is an oversize (.25OS) bearing engineered to restore correct crankshaft thrust tolerances in the Yanmar 3TNV76 engine used in AR16-2 machines. Sourced directly from Multiquip, part 11981002940 meets the original design specification for this application. If you are rebuilding or reconditioning the 3TNV76 engine in your AR16-2, this is the correct oversize thrust bearing to bring journal clearances back within spec.

Key Features

• Oversize Specification for Worn Journals — The .25OS designation means this bearing is sized for crankshafts that have been ground down during reconditioning, restoring proper thrust clearance where a standard-size bearing no longer will.
• Engine-Specific Fit — Matched to the Yanmar 3TNV76 engine, ensuring correct bearing dimensions, oil groove alignment, and seating depth for a direct drop-in during engine rebuild.
• Genuine OEM Component — Manufactured to Multiquip OEM standards, delivering the same material hardness and dimensional tolerancing as the original bearing installed at the factory in the AR16-2 roller.
• Confirmed AR16-2 Fitment — Verified for the Multiquip AR16-2 asphalt ride-on roller, so you can order with confidence during your engine rebuild or scheduled overhaul.
• Protects Crankshaft and Engine Longevity — A correctly sized thrust bearing controls axial crankshaft movement; without it, excess end-play accelerates wear across the crankshaft, connecting rods, and internal engine surfaces.

A thrust bearing controls the side-to-side (axial) movement of the crankshaft inside the engine block. In the Yanmar 3TNV76 engine, the thrust bearing sits at the crankshaft journal and prevents excessive end-play — the small amount of axial movement the crankshaft is allowed. When this bearing wears beyond its service limit, crankshaft end-play increases, leading to accelerated wear on connecting rod bearings, valve timing components, and the crankshaft itself. An oversize thrust bearing like the part is used specifically when the crankshaft journal surface has been machined during reconditioning, returning the running clearance to the correct tolerance range and allowing the engine to perform as designed.
