The Wacker Neuson Knob Recoil Starter is a genuine OEM component designed for a wide range of Wacker Neuson vibratory plates, truss screeds, and modular internal vibrators, including the WP1540A, WP1550A, WPU1550A, and WPU1550AW series. Sourced directly from Wacker Neuson, this part carries the same fit, form, and function as the original installed at the factory. Compatibility extends across VP, WP, WPU, HP, HPG, PT, BT, and D series equipment, making a reliable choice for fleet operators managing multiple machine types. Verify your model number before ordering to ensure a direct match.
Key Features
- Genuine OEM Construction — Molded to the exact grip diameter and pull-cord retention spec of the original, so the starter engages consistently and sits flush in the recoil housing without play or wobble.
- Direct Drop-In Replacement — Mounts to the recoil starter assembly using the original hardware and attachment point, requiring no adapters or modifications to the starter housing.
- Broad Fitment Across Wacker Neuson Lines — Confirmed fit on WP1540A, WP1550A, WPU1550A, WPU1550AW, VP1340AW/WH, VP1550AW/WH, HP50A, HP100A, HPG50A, HPG100A, PT2A, BT24A, BT36A, and D3.5A series machines.
- Consistent Pull Feel — A correctly fitted knob transfers hand force smoothly to the recoil cord, protecting the cord anchor from side-load stress that accelerates fraying and breakage at the tie-off point.
- Operator Safety at Every Start — A cracked or loose starter knob can slip during a pull attempt, causing hand strain or loss of control at startup; replacing a worn knob restores a secure, predictable grip before each pull.
The recoil starter knob is the operator's direct interface with the engine's pull-start system. It transfers hand force to the recoil cord, allowing the starter mechanism to spin the engine over for ignition. When the knob cracks, chips, or works loose from the cord anchor, it compromises grip and places uneven stress on the recoil cord itself — leading to cord fraying, failed starts, and potential knuckle injuries if the knob releases mid-pull. Replacing a worn or damaged knob with a genuine OEM part restores a firm, consistent grip and protects the broader recoil assembly from secondary wear.
