The Wacker Neuson Choke Extension Spring is a genuine OEM component designed for the RD12A-90 and RD12-90 series tandem rollers. As a direct-from-manufacturer part, it meets the exact tension and geometry specifications of the original, ensuring the choke mechanism operates exactly as intended. Compatible across multiple RD12 configurations — including solid ROPS, foldable ROPS, and green-series variants — this spring is the correct replacement when the original has fatigued, lost tension, or broken. Confirm your machine's model number before ordering to ensure an accurate match.
Key Features
- Correct Spring Rate for Choke Operation — manufactured to the original tension specification, so the choke opens and closes with the proper resistance for reliable cold-start performance.
- Genuine OEM Part — sourced directly from Wacker Neuson, this is the same spring installed at the factory, carrying the full OEM part number 5000153534 for confident identification.
- Broad RD12 Series Coverage — fits RD12A-90 and RD12-90 tandem rollers across solid ROPS, foldable ROPS, and green-series configurations.
- Drop-In Replacement — matches the original attachment points and coil dimensions, so installation requires no modification to the choke linkage assembly.
- Restores Cold-Start Capability — a fatigued or broken choke spring prevents the choke from holding its set position, leading to difficult starts in cold conditions; replacing it restores full choke function.
The choke extension spring holds tension on the choke linkage, keeping the choke plate in the correct open or closed position during engine starting and warm-up. Without adequate spring tension, the choke can flutter or fail to hold position, making cold starts unreliable and causing the engine to run lean until fully warmed. When this spring stretches, weakens, or breaks, replacing it promptly restores consistent choke control and protects against unnecessary engine strain at startup.
