Detailed Product Overview

URO 6012001773 is a belt tensioner adjuster for Mercedes-Benz diesel engines that rely on consistent accessory belt tension. By matching OE dimensions and material requirements, this component supports correct belt tracking and helps keep the belt system operating as intended. It is a practical replacement choice for owners searching for a Mercedes-Benz 300D belt tensioner adjuster, 300SDL belt tensioner adjuster, or 300TD belt tensioner adjuster.

This part cross-references URO-003459 for the same application. The URO 6012001773 part number is also listed under 601 200 1773.

What It Helps Address

• Belt squeal caused by inconsistent tension
• Misalignment that can affect belt tracking
• Reduced accessory drive performance from worn tension control
• Noise and vibration from a fatigued adjuster assembly
• Premature belt wear related to improper pulley positioning

Installation Notes

Verify the engine range and model listing before installation, especially on 300D and 300SD applications with range-specific notes. Inspect the belt, pulleys, and related tensioning components during service so the new adjuster can operate against a clean, properly aligned belt path. Confirm the adjuster moves smoothly and the belt tracks correctly after installation.
