The Bomag 58004178 Joint Bar is a genuine OEM replacement part designed for Bomag BW 145, BW 177, and BW 213 series single drum rollers, as well as the C 825 C single drum roller. Sourced directly from Bomag, this joint bar matches the original component in material, dimensions, and fit — ensuring it drops in without modification. Coverage spans multiple generation variants across the BW 124, BW 145, BW 177, and BW 213 families, including DH, PDH, DHC, PDHC, and DH-i configurations.
Key Features
- Genuine OEM Construction — manufactured to Bomag's original material and dimensional specifications for the joint bar, ensuring correct load-bearing performance at every articulation point
- Direct-Fit Replacement — engineered to match the original mounting geometry, so this joint bar installs into the frame joint without rework or adaptation
- Broad Single Drum Roller Coverage — fits BW 124, BW 145, BW 177, and BW 213 series single drum rollers across DH, PDH, DHC, PDHC, and DH-i variants, plus the C 825 C single drum roller
- Structural Integrity Restored — a worn or cracked joint bar allows unwanted play at the articulation joint, degrading steering response and compaction accuracy; this part restores tight, controlled movement
- Verified Part Number Traceability — order with confidence using part number 58004178, cross-referenced against Bomag's OEM catalog for the fitment models listed
The joint bar is a structural connecting component located at the articulation joint of the roller frame. It links the front and rear frame sections, transferring forces through the joint while allowing the controlled pivoting that steers the machine. When a joint bar wears, cracks, or fails, the articulation joint develops excessive play, causing imprecise steering, uneven drum tracking, and accelerated wear on surrounding hardware. Replacing a damaged joint bar promptly restores the mechanical integrity of the frame joint and keeps the roller operating with the control and accuracy that productive compaction work demands.
