The Wacker Neuson Valve Spring Lifter is a genuine OEM component designed for the RD12A-90 tandem roller series, CRT36-26A and CRTv36-26A trowels, BFS 2020AS saw, GS12Ai, and GPS9700A. As a factory-sourced part, the meets original engineering tolerances for spring tension and valve seat geometry — ensuring the valvetrain operates exactly as Wacker Neuson intended. Confirmed fitment spans multiple machine types across the Wacker Neuson lineup, making this a frequently needed service item for dealers and contractors running mixed fleets. Stock this part with confidence knowing it carries the same specification as the component installed at the factory.
Key Features
- Correct Spring Rate for Valvetrain Integrity — Engineered to OEM spring tension spec, maintaining proper valve seating pressure and preventing premature seat wear or valve float.
- Genuine Wacker Neuson OEM Part — Sourced directly from Wacker Neuson, this is the same 5000226434 component used in original production — no substitution or cross-referencing guesswork required.
- Drop-In Replacement — Matches the original mounting position and dimensions, allowing straightforward installation during standard valve service without rework or adaptation.
- Broad Multi-Machine Fitment — Fits RD12A-90 double-drum rollers, CRT36-26A and CRTv36-26A trowels, BFS 2020AS saw, GS12Ai, and GPS9700A generator, covering a wide range of Wacker Neuson equipment with a single part number.
- Protects Engine Longevity — A worn or fatigued valve spring allows inconsistent valve timing and poor combustion sealing, leading to power loss, increased fuel consumption, and accelerated internal engine wear over time.
A valve spring lifter works within the engine's valvetrain to hold the intake and exhaust valves firmly closed against their seats when not actuated by the camshaft. The spring provides the return force that snaps the valve shut after each lift cycle, maintaining compression and combustion efficiency. When a valve spring loses tension or breaks, valves can stay partially open, causing rough running, misfires, compression loss, and — if left unaddressed — serious internal engine damage.
