Multiquip 32077 Helical Gearbox Bearing Kit

The Multiquip 32077 Helical Gearbox Bearing Kit is a genuine OEM component designed for the EHHNK5, HHN34TVD, HHXD5, HHXDF4-DF5, and HHNG5 heavy-duty ride-on power trowel series. As a direct OEM replacement, this kit ensures the helical gearbox is restored to original operating specification, maintaining the power transfer and blade control accuracy these machines demand on the slab. Sourced directly through Multiquip's authorized parts network, the 32077 is the correct service solution when gearbox bearing wear is detected during inspection or maintenance. DHS Equipment stocks genuine Multiquip parts so you can get the right component and get back to finishing concrete.

Key Features

• Genuine OEM Bearing Precision — Manufactured to Multiquip's original tolerancing specifications for the helical gearbox, ensuring proper load distribution and smooth gear mesh under continuous troweling loads.
• Complete Kit Format — Includes all necessary bearing components for a full gearbox bearing service, reducing the chance of a partial repair that leads to repeat failures.
• Confirmed Fitment — Verified for EHHNK5, HHN34TVD, HHXD5, HHXDF4-DF5, and HHNG5 ride-on power trowels — consult your parts manual to confirm applicability to your serial range.
• Restores Gearbox Efficiency — Worn or failed gearbox bearings cause excessive noise, heat buildup, and inconsistent blade speed; replacing with the correct OEM kit brings gear operation back to spec.
• Authorized OEM Part — Part number 32077 is a genuine Multiquip component, not a generic substitute, so fitment and material quality match what was installed at the factory.

The helical gearbox on a ride-on power trowel transfers engine or motor power to the finishing blades, controlling both speed and torque to achieve a consistent concrete surface. The bearings within this gearbox support the rotating gear shafts under significant radial and axial loads generated during operation. When these bearings wear, backlash increases, blade speed becomes uneven, and unchecked deterioration can lead to full gearbox failure — making timely bearing replacement critical to keeping finish quality and machine longevity intact.
