Sourced directly from Bomag, this collar bush is manufactured to the same tolerances and material specifications as the original part it replaces. It fits a wide range of tandem roller configurations, from the BW 141 AD-2 and BW 144 AD-2 through to the BW 205 AD 4 and BW 203 ADO-4, making it a versatile stock item for fleet operators and dealers alike. When you order part number 84090624 from DHS Equipment, you receive an authentic Bomag replacement backed by OEM quality assurance.
Key Features
- Genuine OEM Material Integrity — manufactured to Bomag's original dimensional and hardness specifications, ensuring the bushing holds its bore geometry under sustained compaction loads
- Direct OEM Replacement — replaces the original collar bush with no machining or adaptation, restoring the correct shaft-to-housing fit right out of the box
- Broad Tandem Roller Coverage — fits BW 141, BW 151, BW 154, BW 161, BW 164, BW 190, BW 202, BW 203, and BW 205 tandem rollers across -2 and -4 generation builds, including AC, AD, ADH, ADO, and AM variants
- Preserves Drum Alignment and Control — a correctly seated collar bush maintains precise articulation movement; a worn bush introduces play that degrades steering response and uneven drum contact on the mat
- Authentic Bomag Part Number — order with confidence using part number 84090624, the exact Bomag catalog reference for this application
A collar bush is a cylindrical bearing sleeve fitted between a rotating or pivoting shaft and its housing, providing a low-friction wear surface that absorbs lateral and radial loads. On Bomag tandem rollers, collar bushes are typically found in articulation joints and drum-drive assemblies, where they maintain precise alignment between moving components under the constant vibration and compaction forces the machine generates. When a collar bush wears, clearance builds up in the joint, leading to looseness in steering, increased vibration transmitted to the frame, and accelerated wear on the surrounding components — making timely replacement essential to keeping the roller operating accurately and safely.
