The Wacker Neuson Window Lock is a genuine OEM Window Lock designed for the RD40-130 and RD45-140 series tandem rollers. As a factory-original component, this part is manufactured to the same specifications as the unit installed at the factory, ensuring a direct, hassle-free replacement. It is compatible across a wide range of RD40-130 and RD45-140 variants, including standard, C, O, DPF, and US-spec configurations. Keep your roller cab secure and fully operational with the correct OEM part for the job.
Key Features
- Genuine OEM Locking Integrity — Factory-original construction ensures the latch mechanism engages and holds with the same retention force as the original, maintaining a secure cab enclosure.
- Direct Drop-In Replacement — Designed to align with existing window frame mounting points on RD-series tandem rollers, so installation requires no drilling, cutting, or modification to the cab structure.
- Broad RD-Series Compatibility — Fits the full RD40-130 and RD45-140 model family, including standard, C (canopy), O (open), DPF, and US-spec variants across multiple serial number ranges.
- Secure Cab Environment — A correctly functioning window lock keeps the cab window firmly closed during operation, protecting the operator from dust, debris, and noise intrusion on active compaction sites.
- Operator Safety Compliance — A failed or missing window lock can compromise the cab's protective enclosure. Replacing with the genuine OEM part restores the intended level of operator protection as designed.
The window lock is the latching mechanism that holds the cab window firmly in the closed position during machine operation. It prevents the window from rattling open or swinging unexpectedly due to vibration — a common condition on compaction equipment — which could distract the operator or allow debris to enter the cab. When the lock wears out, breaks, or goes missing, the window can no longer be secured properly, creating both a comfort issue and a potential safety concern that warrants prompt replacement.
