The Wacker Neuson Lock Arm Spacer is a genuine OEM component designed for RD12, RD16, and CB14B series tandem rollers used in soil and asphalt compaction applications. As a direct factory replacement, this spacer maintains the correct dimensional tolerancing within the lock arm assembly, ensuring proper articulation and mechanical alignment during operation. This part is confirmed to fit a broad range of RD12, RD16, and CB14B configurations, including foldable ROPS, hydrostatic, and standard tandem roller variants.
Key Features
- OEM Dimensional Accuracy: — Manufactured to exact Wacker Neuson tolerances, ensuring the lock arm assembly maintains correct spacing and load distribution without binding or play.
- Drop-In Installation: — Engineered to the original profile and bore dimensions, allowing direct installation into the existing lock arm mechanism without modification.
- Broad Tandem Roller Compatibility: — Fits RD12-90, RD12A-90, RD16-90, RD16-100, and CB14B-900/1000 series machines across multiple production configurations, including foldable ROPS and hydrostatic drivetrain variants.
- Structural Integrity Under Compaction Loads: — A correctly fitted spacer keeps the lock arm positioned under the repetitive vibration and compaction forces these rollers generate; a worn or missing spacer can introduce unwanted movement, accelerating wear on surrounding components.
- Genuine Wacker Neuson OEM Part: — Sourced directly from Wacker Neuson, part number 5000163254 carries the same material specification as the original production component.
The lock arm spacer is a precision machined component that maintains the correct clearance and alignment between articulating elements in the roller's lock arm system. By holding the arm at the proper lateral position, it prevents side-load contact between adjacent metal surfaces, which protects both the arm and the surrounding pivot hardware from accelerated wear. When this spacer wears down or is missing entirely, the lock arm can shift out of position under load, leading to abnormal wear on pins, bushings, and structural brackets that are significantly more costly to replace.
