Wacker Neuson 5002001531 Key A8 X 7 X 20

The Wacker Neuson Key A8 X 7 X 20 is a genuine OEM component designed for a wide range of Wacker Neuson compaction and cutting equipment, including the VPH70, VPR70, VPY70, VPG165V, VPG165A, VPG170A, MP70, DPS2040, DPS2050, RS600, RS600A, BFS1214, BFSX1214, BFS 614B, BFS 614AB, MFS14, MFSX14, and MFSX14 (RAW) models. As a genuine Wacker Neuson part, the is manufactured to the same exacting standards as the original component installed at the factory, ensuring a direct, accurate fit with no guesswork. With coverage across single direction vibratory plates, walk-behind rollers, and floor saws, this key is a high-demand service part suited to both scheduled maintenance and breakdown repairs on a broad range of machines.

Key Features

• Genuine OEM Dimensional Accuracy — Manufactured to precise A8 x 7 x 20 dimensions, ensuring correct engagement between mating shaft and hub components without slop or misalignment.
• Drop-In Installation — Slots directly into the existing keyway on compatible shafts, requiring no filing, shimming, or modification to seat correctly.
• Broad Equipment Compatibility — A single part number covering vibratory plates (VPH70, VPR70, VPY70, DPS2040, DPS2050), walk-behind rollers (RS600, RS600A), and floor saws (BFS1214, MFS14, MFSX14, and related models).
• Torque Transfer Integrity — A correctly sized and seated key maintains positive drive between rotating shaft and driven component; an undersized or worn key causes slippage, vibration, and accelerated wear on both mating parts.
• Genuine Wacker Neuson Part — Sourced directly through the Wacker Neuson OEM supply chain, so the material grade, hardness, and geometry match the part the machine was built with.

A woodruff or parallel key such as the 5002001531 Key A8 X 7 X 20 is a small but critical drive component fitted into a machined slot — called a keyway — on a rotating shaft and its mating hub or pulley. Its job is to lock the two parts together rotationally so that torque is transferred cleanly without slippage. When a key wears, shears, or goes missing, the driven component — whether a belt pulley, eccentric weight, or drum — stops turning with the shaft, causing loss of compaction force, erratic vibration patterns, or complete loss of drive. Replacing a damaged key promptly with the correct OEM part restores full power transmission and protects the more expensive shaft and hub from further damage.
