Sourced directly from Bomag, this spring cotter delivers an exact fit across compatible equipment including the BW 75 AD, BW 75 ADL, BW 90 AD, BW 120 AD, BW 124 D, BW 138 AD, and the BM 2000/75 and BM 2500/75 cold milling machines, among others. As a genuine OEM part, part number 05994002 meets the same specifications as the component installed at the factory, ensuring proper retention and secure mechanical connection. Operators and service technicians can install this spring cotter with full confidence in its dimensional accuracy and material integrity.
Key Features
- Genuine OEM Material Grade — manufactured to Bomag's own material and hardness specifications for a spring cotter, ensuring correct retention force and resistance to fatigue under vibration loads
- Drop-In Replacement — matches the original pin dimensions and cotter geometry exactly, seating and locking the same way as the factory-installed component without any rework
- Broad Bomag Compatibility — fits walk-behind light rollers including the BW 75 AD and BW 75 ADL, tandem rollers including the BW 80 AD-2, BW 90 AD-2, BW 100 ADM-2, BW 120 AD, BW 125 ADH, BW 135 AD, BW 138 AD, and BW 900 AD, the BW 124 D single drum roller, and cold milling machines including the BM 2000/75, BM 2200/75, BM 2000/75 TE, and BM 2500/75
- Vibration-Resistant Retention — spring cotters are specifically engineered to hold pins and shafts securely under the continuous vibration and dynamic loading that compaction and milling equipment generates; a failed or missing cotter can allow critical pins to walk free
- Correct Part, Verified Number — ordering by genuine Bomag part number 05994002 eliminates the guesswork of cross-referencing aftermarket substitutes, keeping your service records accurate and your machine running as designed
A spring cotter is a small but critical fastening device used to lock pins, clevis bolts, and shafts in place within mechanical assemblies. By passing through a drilled hole and spreading its legs, it prevents the pin from backing out or rotating unintentionally, even under the sustained vibration produced by rollers and cold milling machines during operation. When a spring cotter is missing, worn, or improperly installed, the pin it secures can shift or eject entirely, leading to looseness in linkages or control assemblies and potential mechanical failure.
