Wacker Neuson 5100012686 Water Tank for RD24-100, RD27-120 & RD28-120 Tandem Rollers

The Wacker Neuson Water Tank is a genuine OEM Water Tank designed for the RD24-100, RD27-120, and RD28-120 series Tandem Rollers, including standard, C, and O variants across multiple production generations. As a direct OEM replacement, part is manufactured to Wacker Neuson's exact specifications, ensuring a correct fit without any guesswork. This tank covers an extensive range of Tandem Roller configurations — from early RD24-100 and RD27-120 models through to the RD24-100.3, RD27-120.3, and their US-market equivalents. If your roller is running low on drum spray water or the existing tank is cracked or damaged, this is the part you need to restore full operation.

Key Features

• Genuine OEM Construction — Manufactured by Wacker Neuson to the same material and dimensional standards as the original tank, ensuring correct capacity and fitment without improvisation.
• Drop-In Replacement — Mounts directly into the existing tank bracket and connects to OEM hose fittings on the drum spray system, so installation is straightforward for any qualified technician.
• Broad Tandem Roller Coverage — Fits RD24-100, RD27-120, and RD28-120 series rollers across standard, C (combination), O (offset), and US-market variants, spanning multiple production generations.
• Protects Drum Surface and Asphalt Quality — A fully functional water tank keeps the drum spray system supplied, preventing asphalt from sticking to the drums and maintaining a clean, consistent compaction surface on every pass.
• Verified Part Number — Sourced and supplied as Wacker Neuson 5100012686, so you can order with confidence that this is the correct OEM component for your machine's serial range.

The water tank on a Wacker Neuson Tandem Roller serves as the reservoir for the drum wetting system, supplying water to spray nozzles that keep both drums moist during asphalt compaction. This continuous wetting prevents hot mix from adhering to the steel drum surface, which would otherwise cause tearing and an uneven mat finish. When the tank is cracked, leaking, or damaged, the spray system loses pressure or runs dry — leading to material pickup on the drums and compromised compaction results.
