The Wacker Neuson Locking Plate is a genuine OEM component designed for the RD40-130 and RD45-140 series tandem rollers, including standard, C, and O variants across both the original and.3 model generations. Sourced directly from Wacker Neuson, this part is manufactured to the exact tolerances and material specifications of the original, ensuring it seats and engages correctly without any guesswork on fitment. Compatible across a broad range of RD-series models — including the RD40-130, RD40-130 C, RD40-130 O, RD45-140, RD45-140 C, RD45-140 O, and their.3 counterparts — this locking plate is the straight swap your machine needs. When you're sourcing critical retention hardware, going genuine OEM means you're getting the part built for the job.
Key Features
- Genuine OEM Retention Integrity — Manufactured by Wacker Neuson to the same hardness and dimensional spec as the original, so the plate locks and holds under the vibratory loads these rollers generate.
- Drop-In Installation — Matches original mounting geometry exactly, slotting into position the same way the factory part does with no rework or adaptation to mating components.
- Broad RD-Series Fitment — Covers RD40-130 and RD45-140 tandem roller families across standard, C, O, and .3 variants, making it a single-part solution for fleets running mixed RD-series machines.
- Keeps Critical Assemblies Secured — A worn or missing locking plate allows components to shift or back out during operation; replacing it promptly restores the retention function the assembly depends on.
- Verified Part Number — Ordering by Wacker Neuson part number 5100012997 confirms you're getting the correct plate for your specific model — eliminating the risk of receiving a similar but incompatible part.
A locking plate is a hardened retention component used to prevent fasteners, shafts, or assemblies from rotating or backing out under load and vibration. On tandem rollers like the RD40-130 and RD45-140, where continuous vibratory compaction forces are transmitted through the machine's drivetrain and drum assemblies, these plates play a quiet but essential role in keeping critical hardware positively located. When a locking plate cracks, deforms, or goes missing, the assembly it secures becomes vulnerable to movement and wear — leading to accelerated damage to surrounding components if not addressed.
