The Wacker Neuson 5100038917 Cap is a genuine OEM replacement designed for the RD27-100 and RD27-120 tandem roller series. Sourced directly through the Wacker Neuson parts program, this cap ensures an exact match to the original component specification. It is compatible across both the Roller Pro T4F and Roller Basic T4F configurations of the RD27 series, making it the correct choice for operators running either variant on the jobsite.
Key Features
- Genuine OEM Construction: — Manufactured to the same material and dimensional tolerances as the part originally installed on your RD27 tandem roller, ensuring consistent fit and sealing performance.
- Drop-In Replacement: — Matches the original mounting interface and profile exactly, so installation follows the same procedure as the factory part with no rework or adaptation needed.
- Broad RD27 Series Coverage: — Fits both the RD27-100 and RD27-120 in Roller Pro T4F and Roller Basic T4F configurations, covering the full Tier 4 Final lineup within this roller family.
- Protects Internal Components: — A properly seated cap keeps contaminants, moisture, and debris out of the assembly it covers, preventing premature wear or damage to the components beneath it.
- Verified Part Number: — Order with confidence using part number 5100038917, confirmed against the Wacker Neuson RD27-100 and RD27-120 parts references for both Pro and Basic T4F machines.
A cap serves as a protective closure for a port, reservoir, shaft end, or housing on the machine. Its primary role is to seal the opening it covers against dust, water, and debris intrusion that could compromise underlying components or fluids. When a cap is cracked, missing, or no longer seating correctly, the exposed area becomes vulnerable to contamination — which can lead to accelerated wear, fluid loss, or component failure in the assembly it was protecting. Replacing a damaged or lost cap promptly is a straightforward step that preserves the integrity of the broader system.
