The Wacker Neuson Fitting Key is a genuine OEM component designed for a broad range of Wacker Neuson reversible vibratory plate compactors and vibratory trench rollers, including the RT560, RT820, BPU 2540A, BPU 3050A, BPU 3750Ats, DPU 2440H, DPU 2540H, DPU 3050H, DPU 3060H, DPU 3070H, DPU 3750Hts, and related series. Sourced directly from Wacker Neuson, part number carries the same quality and dimensional accuracy as the component installed during original assembly. This fitting key covers an extensive fitment range spanning both BPU gasoline reversible plate compactors and DPU diesel reversible plate compactors, as well as RT-series vibratory trench rollers, making it a high-utility stocking part for dealers and service technicians. Verify your machine's model and serial number against the fitment list before ordering to confirm compatibility.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to exact Wacker Neuson tolerances, ensuring the key seats and locks correctly without play or misalignment in the keyway.
- Drop-In Replacement — Matches the original profile and length, allowing direct installation into the existing keyway without machining or modification of mating components.
- Wide Fitment Coverage — Compatible with RT560 and RT820 vibratory trench rollers, BPU 2440A through BPU 3750Ats gasoline reversible plate compactors, and DPU 2430F through DPU 3760Hets diesel reversible plate compactors across multiple production series.
- Torque Transmission Integrity — A correctly fitted key maintains positive drive between shaft and hub; a worn or missing key causes slippage, uneven compaction output, and accelerated wear on mating drive components.
- Positive Drive Safety — On vibratory compaction equipment, key failure can result in loss of eccentric drive control; replacing a worn key promptly restores safe, predictable machine operation.
A fitting key is a small, precision-machined component that sits in a machined slot — called a keyway — cut into both a shaft and its mating hub or pulley. Its role is to lock the two components together rotationally, so torque is transferred from the shaft to the driven component without slippage. On vibratory plate compactors and trench rollers, fitting keys are commonly found in the exciter drive assembly and other rotating drive interfaces. When a fitting key shears, deforms, or works loose, the driven component can spin freely on the shaft, resulting in lost compaction force, erratic machine behavior, or damage to the shaft and hub surfaces — making prompt replacement essential to restoring full machine output.
