The Bomag 87180222 Water Tank is a genuine OEM component designed for BW 170 AP AM, BW 174 AP, BW 174 ACP, BW 174 ACP-AM, and BW 174 AP-AM tandem rollers. As a direct OEM replacement, this water tank matches the original specification, ensuring it mounts and connects exactly as the factory-installed unit. If your current tank is cracked, leaking, or degraded, this part restores proper drum wetting performance and keeps your tandem roller running as intended.
Key Features
- Genuine OEM Construction — sourced directly from Bomag, this water tank is manufactured to the same material and dimensional standards as the original, so capacity and fitment are never a compromise
- Direct Drop-In Replacement — engineered to align with the existing mounting points and plumbing connections on compatible tandem rollers, with no reworking of brackets or fittings required
- Broad Tandem Roller Coverage — confirmed fit across the BW 170 AP AM and BW 174 AP, BW 174 ACP, BW 174 ACP-AM, and BW 174 AP-AM tandem roller lineup
- Sustained Drum Wetting Performance — a correctly sized and sealed water tank maintains consistent water flow to the drums, preventing asphalt pickup during compaction passes and protecting mat quality
- Part Number Confidence — order by Bomag part number 87180222 to ensure you receive the exact replacement intended for your machine, eliminating guesswork on fitment
The water tank on a tandem roller stores the supply of water used to continuously wet the compaction drums during asphalt rolling operations. Keeping the drums moist prevents hot asphalt from sticking to the steel surface, which would otherwise cause tearing and uneven compaction in the mat. When the tank cracks, leaks, or fails to hold volume, drum wetting becomes inconsistent, leading to material pickup, surface defects, and the need to halt work mid-pass to address the issue.
