The Wacker Neuson is a genuine OEM Fuel Cap Ratcheting Vented designed for RD27-100 and RD27-120 series tandem rollers. As a factory-authorized component, it meets the exact material and venting specifications of the original part installed at the time of manufacture. This cap fits across multiple RD27 configurations, including the RD27 Pro Tandem Roller and standard Ride-On Roller variants, making it a reliable stock item for fleets running multiple RD27 units. Keep part number on hand to avoid unnecessary delays during routine maintenance or field replacement.
Key Features
- Ratcheting Mechanism Integrity — The ratcheting closure ensures the cap seats firmly and consistently without over-tightening, maintaining a repeatable seal every time the tank is accessed.
- Calibrated Venting for Tandem Roller Fuel Systems — The integrated vent is sized to balance fuel tank pressure correctly for the RD27 platform, preventing vapor lock and allowing proper fuel flow to the engine.
- Genuine OEM Construction — Sourced directly from Wacker Neuson, this cap is manufactured to the same material grade and dimensional tolerances as the part it replaces — not an approximation.
- Broad RD27 Series Coverage — Fits RD27-100 and RD27-120 machines across numerous serial number ranges, including RD27 Pro and standard Ride-On Roller configurations.
- Fuel System Safety — A properly functioning vented cap prevents excess pressure buildup in the fuel tank and reduces the risk of fuel spillage during operation on sloped or vibrating surfaces — both common conditions for a tandem roller on an asphalt paving pass.
The fuel cap seals the tank opening to prevent dirt, debris, and moisture from contaminating the fuel supply while allowing controlled pressure equalization through its built-in vent. On a vibratory tandem roller like the RD27 series, the machine operates under continuous vibration and frequent grade changes, which puts added stress on the fuel cap's seal and venting function. A cracked, missing, or non-venting cap can cause fuel starvation, rough engine operation, or fuel spillage — all of which interrupt compaction work and create a hazardous condition on the paving site.
