The Wacker Neuson A8.0 x 7 x 22 Key is a genuine OEM component designed for the RD25 Hydrostatic Double Drum Vibratory Roller, BFS 2575KLS Floor Saw, and DFS 2075HLS Diesel Walk-Behind Saw. Sourced directly from Wacker Neuson, part number meets the exact dimensional and material specifications required for proper drivetrain engagement across these machine families. Confirming your model and machine number before ordering ensures a direct, hassle-free installation.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to Wacker Neuson's exact A8.0 x 7 x 22 profile, ensuring correct shaft-to-hub engagement without recutting or shimming.
- Direct Drop-In Installation — Matches the original keyway geometry on RD25 roller and saw driveshaft assemblies, seating flush for immediate torque transfer.
- Broad Cross-Family Fitment — Compatible with the RD25 tandem roller (multiple machine numbers), BFS 2575KLS Floor Saw, and DFS 2075HLS Diesel Walk-Behind Saw.
- Torque Integrity Under Load — A correctly fitted drive key locks the shaft and hub in precise rotational alignment; a worn or missing key causes slippage, uneven drive output, and accelerated keyway wear on both mating components.
- OEM Material Grade — Produced from the same material specification as the original, maintaining the shear strength needed to handle the cyclic loading demands of vibratory roller and saw driveline applications.
A drive key is a small but critical mechanical fastener that sits in a machined slot — the keyway — between a rotating shaft and its mating hub or gear. Its role is to lock the two components together rotationally so that torque is transferred cleanly without slippage. When a key shears or wears, the shaft and hub can rotate independently, causing loss of drive, vibration, noise, and rapid damage to the surrounding keyway surfaces. Replacing a worn key promptly with the correctly sized OEM part protects the more expensive shaft and hub components from secondary damage.
