Key Features
- Genuine OEM Construction: — Manufactured to the same material and dimensional tolerances as the original, ensuring the cap seats and seals exactly as intended on RD27 series rollers.
- Drop-In Replacement: — Designed to install directly in place of the original cap with no rework or adaptation needed on the host assembly.
- Broad RD27 Fitment: — Confirmed for RD27-100 and RD27-120 tandem rollers across Pro, Basic, T4F, and Ride-On Roller configurations.
- Protects the Host Assembly: — A properly fitted cap keeps contaminants, moisture, and debris out of the port or reservoir it covers, preventing premature wear or damage to the components beneath.
- Correct Part Number Assurance: — Ordering by Wacker Neuson part number 5200004858 eliminates the risk of receiving a mismatched or incompatible substitute.
A cap on a vibratory tandem roller serves as a closure and barrier for a fluid port, filler neck, or service access point on the machine. It keeps the sealed system protected from dirt ingestion and moisture intrusion during operation and between service intervals. When a cap is cracked, missing, or no longer seating correctly, it exposes the underlying system to contamination that can lead to accelerated component wear or fluid loss — making timely replacement an important part of routine roller maintenance.
