The Bomag 05817964 Loop Ring is a genuine OEM component designed for Bomag BW 177, BW 179, BW 161, BW 190, BW 202, BW 203, and BW 205 single drum rollers and tandem rollers. Sourced directly from Bomag, this loop ring meets the same specifications as the original part installed at the factory. It fits across multiple generation variants of these roller families, making it a dependable choice when servicing or rebuilding machines in this lineup. Confirm your model and serial number against the fitment list to ensure this is the correct part for your machine.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original material and dimensional specifications, ensuring the ring seats and functions exactly as the original hardware does in these roller assemblies
- Direct OEM Replacement — part number 05817964 installs as a direct swap for the original loop ring, requiring no rework or adaptation to the surrounding hardware
- Broad Roller Coverage — fits BW 177, BW 179, BW 161, BW 190, BW 202, BW 203, and BW 205 series machines, spanning both single drum and tandem roller configurations across multiple production generations
- Structural Integrity Under Load — a correctly functioning loop ring maintains secure connections within the roller's hydraulic or mechanical circuit; a worn or failed ring can lead to loosening, leakage, or loss of connection integrity during compaction operations
- Multi-Generation Fitment — covers DH-3, DH-4, DH-50, PDH-3, PDH-4, PDH-50, AD-4, ADH-4, ADO-4, DHC-4, PDHC-4, and AM variants, giving technicians confidence when ordering across a mixed fleet of Bomag rollers
A loop ring is a retaining or connecting ring used to secure hose assemblies, hydraulic lines, or mechanical linkages at junction points within the machine. It holds the connected components in position under the vibration and dynamic loads generated during compaction work, preventing movement or separation that could disrupt hydraulic flow or mechanical function. When a loop ring becomes worn, cracked, or deformed, it can no longer maintain a secure hold — leading to line movement, potential leakage, or accelerated wear on adjacent components.
