The Wacker Neuson Valve Collar Lifter is a genuine OEM component designed for a broad range of Wacker Neuson equipment, including the RD12A-90 Tandem Roller series, CRT36-26A and CRTv36-26A Trowels, BFS 2020AS Saw, GS12Ai, and GPS9700A. Sourced directly from Wacker Neuson, this part is manufactured to the exact specifications of the original, ensuring a direct, drop-in replacement with no guesswork. Confirmed fitment spans multiple machine families, making a versatile stock item for dealers, rental fleets, and service shops running Wacker Neuson equipment.
Key Features
- OEM Valve Geometry: — Manufactured to the precise dimensional tolerances required for correct collar engagement and lifter travel — critical for consistent valve actuation across operating conditions.
- Direct Drop-In Replacement: — Matches the original mounting interface and connection points, so installation follows the standard service procedure without additional fitting or adjustment.
- Broad Wacker Neuson Fitment: — Verified for RD12A-90 and CRT36-26A / CRTv36-26A series machines, plus BFS 2020AS, GS12Ai, and GPS9700A — one part number covering multiple product lines.
- Consistent Valve Lift Performance: — A correctly functioning Valve Collar Lifter maintains accurate lift timing and stroke; a worn or damaged collar can cause erratic valve actuation, power loss, or engine damage.
- Genuine Wacker Neuson Part: — Supplied as genuine OEM, meaning the material grade, hardness, and surface finish are identical to what left the factory — no compromise on wear life or fit.
The Valve Collar Lifter is part of the valve train assembly and works by guiding the movement of the valve lifter as it follows the camshaft lobe, transferring that motion to open and close the engine's intake or exhaust valve at the correct time. The collar component keeps the lifter properly aligned during its travel, preventing lateral movement that would cause uneven wear or missed valve events. When the collar becomes worn, cracked, or seated incorrectly, valve timing suffers — leading to rough running, reduced power output, and accelerated wear on surrounding valve train components.
