Wacker Neuson 5100059884 Fitting Key 7x7x33

The Wacker Neuson Fitting Key 7x7x33 is a genuine OEM component designed for the RD7Af HRC, RD7Afb HRC, and BT48A series machines. Sourced directly from Wacker Neuson, this key is manufactured to the exact dimensions and material specifications required for proper shaft-to-hub engagement in these machines. Genuine OEM status means matches the original part in every critical respect, ensuring a correct installation without adjustment or guesswork. If you're servicing an RD7Af HRC, RD7Afb HRC, or BT48A, this is the specified replacement key.

Key Features

• Exact Dimensional Accuracy — A 7x7x33 profile matched to Wacker Neuson's original specification keeps the key seated correctly and transmits torque without slop or play.
• Genuine OEM Part — Supplied by Wacker Neuson, this fitting key carries the same material grade and dimensional tolerances as the part installed at the factory.
• Direct Drop-In Replacement — Designed to seat into the original keyway without filing, shimming, or modification, making installation straightforward in the field.
• Confirmed Fitment — Verified for the RD7Af HRC, RD7Afb HRC, and BT48A series, so you can order with confidence knowing part number 5100059884 is the correct key for your machine.
• Sustained Power Transfer — A correctly fitted key locks the rotating assembly in proper alignment; a worn or incorrectly sized key allows shaft slippage that accelerates damage to both mating components.

A fitting key is a small but critical drive component that locks a rotating shaft to a mating hub, pulley, or gear, preventing rotational slippage between the two parts. By sitting in precisely machined keyways cut into both the shaft and the hub, it transfers torque evenly across the drive assembly. When a fitting key wears, shears, or is incorrectly sized, the resulting shaft slippage causes rapid wear to the keyway itself and can lead to broader drivetrain damage that is far more costly to repair than replacing the key alone.
