The Bomag 07990008 Square Key is a genuine OEM replacement built for BW 75 ADL and BW 75 AD walk-behind light rollers. Sourced directly from Bomag, this square key matches the original component specification exactly, ensuring a proper mating fit between shaft and hub without any guesswork. This part is confirmed compatible with both the BW 75 ADL and BW 75 AD, making it a straightforward drop-in replacement when servicing these machines. When you need to restore correct power transfer and keep your roller running as intended, ordering by part number 07990008 guarantees you receive the right component every time.
Key Features
- Genuine OEM Torque Integrity — manufactured to Bomag's original dimensional tolerances, ensuring the key seats fully in its keyway slot without play or slippage under load
- Direct Shaft-to-Hub Fit — machined to the exact profile of the original, this square key installs directly into the drive assembly of the BW 75 ADL and BW 75 AD without filing or fitting
- Confirmed Fitment — verified for BW 75 ADL and BW 75 AD walk-behind light rollers, so you can order part number 07990008 with confidence
- Protects Drive Components — a correctly fitted square key prevents shaft and hub wear caused by rotational slipping, extending the service life of surrounding drive parts
- Fast, Low-Cost Service Fix — replacing a worn or sheared key at service is far less costly than addressing downstream damage to shafts, hubs, or drive assemblies left running without one
A square key is a small but critical drivetrain component that locks a rotating shaft to a hub, pulley, or gear, ensuring both parts turn as a single unit. When the key is worn, sheared, or missing, the shaft spins independently inside the hub, causing loss of drive, accelerated wear on mating surfaces, and potential damage to surrounding components. Replacing a failed square key promptly with the correct OEM part restores full power transmission and prevents what is otherwise a minor service item from becoming a costly drivetrain repair.
