Key Features
- Genuine OEM Sealing Integrity — Manufactured to Bomag's original material and tolerance specs, this filler cap delivers the same compression seal as the factory-installed component — critical for preventing fluid contamination and leaks.
- Direct Drop-In Replacement — Matches the original mounting thread, cap profile, and retaining mechanism on covered machines, so installation requires no modification or rework.
- Broad Roller Coverage — Fits Bomag single drum rollers including the BW 177 D-3, BW 177 DH-3, BW 177 PDH-3, BW 178 D-3, BW 212 D-3, BW 213 D-3, BW 213 DH-3 USA, BW 213 PDH-3, BW 213 PDH-3 USA, and C 850 C, as well as tandem rollers including the BW 180 AD, BW 184 AD, BW 184 AD-2, and BW 184 AD-2 AM.
- Contamination Protection — A properly seating filler cap keeps dirt, debris, and moisture out of the fluid reservoir — a worn or ill-fitting cap can introduce contaminants that accelerate internal wear and cause costly damage.
- Verified Part Number Fitment — Ordering by Bomag part number 31711322 ensures you receive the exact cap engineered for your machine, eliminating the guesswork of cross-referencing aftermarket alternatives.
The filler cap seals the fluid reservoir fill port on your roller, preventing dirt, water, and other contaminants from entering the system while keeping fluid from escaping during operation. A tight, correctly fitted cap is essential to maintaining fluid cleanliness and system pressure — a cracked, stripped, or missing cap can quickly lead to fluid loss or contamination that damages hydraulic or engine components. Replacing a worn filler cap with a genuine Bomag 31711322 restores that protective seal and keeps the machine operating within its designed parameters.
