The Wacker Neuson Fitting Key B 5x5x30 is a genuine OEM component designed for the BFS735 floor saw series and BPS1135A Single Direction Vibratory Plate. Sourced directly from Wacker Neuson, this part meets the exact dimensional and material standards of the original — so it seats and locks correctly without any guesswork. Confirmed fitment also extends to the BFS 735A Gasoline Powered Floor Saw and BFS735 CN variants, making it the right call for operators running multiple machines in the same family.
Key Features
- OEM-Grade Dimensional Accuracy — Manufactured to Wacker Neuson's exact 5x5x30 key profile, ensuring the correct fit between mating shaft and hub components without tolerance-related slop or binding.
- Direct Drop-In Installation — Matches the original keyway geometry on BFS735 and BPS1135A driveline components, sliding into place without filing, shimming, or rework.
- Broad BFS735 and BPS Series Fitment — Compatible with the BFS735, BFS735 CN, BFS 735A Gasoline Powered Floor Saw, and BPS1135A Single Direction Vibratory Plate — one part covering an entire machine family.
- Torque Transmission Integrity — A correctly fitted key locks the rotating components in proper angular alignment, maintaining full power transfer from the drive shaft to the driven component without slip or wear escalation.
- Genuine Wacker Neuson Part — Carrying part number 5002000090, this is an authorized OEM replacement backed by Wacker Neuson's parts supply chain — not a generic substitute.
A fitting key is a small but critical driveline component that sits in a machined slot — the keyway — shared between a shaft and a hub, pulley, or gear. Its job is to prevent rotational slipping between those two parts, transferring torque from one to the other as a mechanical lock. When a fitting key wears, shears, or goes missing, the driven component loses its positive drive connection: the shaft spins freely while the hub or pulley lags or stops entirely, which can result in loss of blade drive on a floor saw or disrupted eccentric drive on a vibratory plate. Replacing a damaged key promptly with the correct OEM part restores full driveline engagement and prevents secondary wear damage to the keyway itself.
