Multiquip 71971702900 Main Bearing Set 3TNV76-NAMM AR16-2

The Multiquip 71971702900 is a genuine OEM Main Bearing Set 3TNV76-NAMM AR16-2 designed for the AR16-2 asphalt ride-on roller. As a direct OEM replacement sourced through Multiquip's authorized parts network, this bearing set is manufactured to the same specifications as the original component installed at the factory. Fitment is confirmed for AR16-2 series equipment, making it the correct choice when restoring engine integrity on that platform. DHS Equipment stocks this part to keep your roller back in service without the guesswork of cross-referencing aftermarket alternatives.

Key Features

• OEM-Grade Bearing Tolerances — Manufactured to the precise dimensional and surface-finish specifications of the original 3TNV76-NAMM engine bearings, ensuring correct oil film clearance and crankshaft support.
• Direct Engine Drop-In — Engineered to seat directly into the 3TNV76-NAMM engine block on the AR16-2, matching the original bearing housing dimensions for a straightforward installation during an engine rebuild.
• Confirmed AR16-2 Fitment — Verified compatibility with the Multiquip AR16-2 asphalt ride-on roller; use part number 71971702900 to confirm the correct set for your machine before ordering.
• Crankshaft Protection — Properly sized main bearings maintain the oil film that separates the crankshaft from the block, preventing metal-to-metal contact and protecting the engine from accelerated wear or catastrophic failure.
• Genuine Multiquip OEM Part — Supplied directly through Multiquip's authorized parts channel, this bearing set meets the same material and hardness standards as the original, giving you confidence in long-term engine performance after a rebuild.

Main bearings are the load-bearing interface between the engine crankshaft and the engine block. They support the crankshaft as it rotates under the stress of combustion cycles, relying on a pressurized oil film to prevent direct metal contact. When main bearings wear, that oil clearance increases, causing a drop in oil pressure, audible knocking under load, and eventually crankshaft damage that can render the engine unrepairable. Replacing the bearing set at the correct service interval — or during any engine rebuild — restores proper clearances, protects the crankshaft journal surfaces, and returns the engine to full operating condition.
