The Bomag 05994003 Spring Cotter is a genuine OEM fastening component designed for a broad range of Bomag pavers, tandem rollers, single drum rollers, and walk-behind rollers. This spring cotter delivers a direct, verified fit across Bomag paver models including the BF 900 C S600, BF 900 C S500, BF 700 C-2 S 600, BF 700 C-2 S 500, BF 700 C S500, BF 600 C-2 S 500, BF 600 P-2 S 500, and BF200C 2, as well as tandem rollers including the BW 120 AD, BW 120 AD-4, BW 120 AC-4, BW 125 AD-4, BW 125 AC-4, BW 100 AD-4, BW 100 AC-4, and BW120AD 4, single drum rollers including the BW 213 DH-4, BW 213 DH 4, BW 213 DH-4i, and BW 213 DH 4I, and walk-behind rollers including the BW 75 ADL and BW 75 E. Sourced directly from Bomag, this part matches the original in material, dimensions, and retention performance. Keeping your equipment running with genuine components means no guesswork on fitment or compatibility.
Key Features
- Genuine OEM Retention Integrity — manufactured to Bomag's exact material and dimensional standards for a spring cotter, ensuring consistent clamping force and secure pin retention across service life
- Drop-In Replacement — installs directly in the same bore and pin position as the original, requiring no reworking of adjacent hardware or fastener seats
- Broad Equipment Coverage — fits Bomag pavers including the BF 900 C S600 and BF 700 C-2 S 600, tandem rollers including the BW 120 AD-4 and BW 125 AD-4, single drum rollers including the BW 213 DH-4 and BW 213 DH-4i, and walk-behind rollers including the BW 75 ADL and BW 75 E
- Secure Pin and Shaft Locking — a correctly fitted spring cotter prevents axial movement of shafts, pins, and clevis connections; a missing or fatigued cotter can allow critical linkages to shift or separate under load
- Safety-Critical Fastener — spring cotters are commonly used to secure control linkages, pivot pins, and actuator connections; using a correctly rated OEM cotter reduces the risk of linkage disengagement during operation
A spring cotter — also known as a cotter pin or split pin — is a small but essential fastening element used to lock pins, bolts, and shafts in position within mechanical assemblies. Once inserted through a drilled hole in a pin or shaft and bent outward, it prevents the pin from backing out under vibration or load. On compaction and paving equipment that operates under continuous vibration, worn or absent cotters can allow pivot pins and control linkages to migrate, leading to imprecise machine response or component separation. Replacing a fatigued or missing spring cotter promptly restores the mechanical integrity of the assembly it secures.
