The Multiquip 493296 Pinion Shaft Bearing is a genuine OEM component designed for MC44S concrete mixers and WTB-16 and WTB-16PD power buggies. As a factory-sourced part, it meets the original engineering tolerances required to maintain smooth, low-friction rotation at the pinion shaft — a critical interface in the drivetrain of these machines. Confirmed fitment covers the MC44S, WTB-16, and WTB-16PD, so you can order with confidence knowing this bearing is the correct specification for your equipment. DHS Equipment supplies this part direct as an authorized Multiquip OEM replacement.
Key Features
- Precision Bearing Tolerances — Manufactured to OEM dimensional specifications, ensuring correct radial clearance and load capacity at the pinion shaft interface.
- Drop-In Fitment — Engineered to seat directly into the original bearing housing with no machining or adapting required for MC44S, WTB-16, and WTB-16PD models.
- Confirmed Model Compatibility — Verified fitment for MC44S concrete mixers and WTB-16 and WTB-16PD power buggies.
- Sustained Drivetrain Performance — A correctly functioning pinion shaft bearing allows smooth, consistent power transfer through the drivetrain; a worn bearing introduces play, vibration, and accelerated gear wear.
- Genuine OEM Sourcing — Supplied directly from Multiquip, carrying the same part number and quality standard as the bearing installed at the factory.
The pinion shaft bearing supports the pinion gear on its shaft, allowing it to rotate smoothly under load while maintaining precise alignment with the mating gear in the drivetrain. In equipment like concrete mixers and power buggies, this bearing absorbs both radial and axial forces generated during operation, keeping the gear mesh tight and efficient. When this bearing wears or fails, the resulting play in the shaft causes increased noise, vibration, uneven gear wear, and — if left unaddressed — drivetrain damage that extends well beyond the bearing itself.
