Key Features

• Genuine OEM Construction — manufactured to Bomag's original material and dimensional standards, ensuring the cap forms a proper seal and retains its locking function under real-world operating conditions
• Broad BW-Series Coverage — fits Bomag tandem rollers including the BW 100 AC-3, BW 120 AD-3, BW 135 AC, BW 138 AD, BW 141 AD-2, BW 151 AC-2, and BW 154 AD-2, as well as single drum rollers including the BW 124 DH-3, BW 145 D-3, BW 145 PDH-3, C 815 C, and C 825 C, among others
• Drop-In Replacement — engineered to the original thread profile and cap geometry so this locking cap installs directly into the correct port or filler opening without modification
• Secure Retention — a properly functioning locking cap prevents fluid loss, contamination ingress, and pressure leaks; a worn or missing cap can lead to fluid-system faults and accelerated component wear
• Verified Part Number — ordering by part number 05712963 ensures you receive the exact Bomag-specified cap matched to these machine families, eliminating costly trial-and-error returns

A locking cap seals and secures an access point — typically a fluid reservoir, filler neck, or service port — on the roller's hydraulic, fuel, or lubrication system. It prevents contaminants such as dust, water, and debris from entering the system while also retaining fluid under operating pressure or vibration. When a locking cap is cracked, stripped, or missing, the resulting contamination or fluid loss can cause accelerated wear or outright failure of the components it protects, making timely replacement an important part of routine service on any Bomag roller.
