The Multiquip 20043 Drive Bearing Shaft 1.0 Dia x 12.88 Comet Only is a genuine OEM component designed for Whiteman mechanical ride-on power trowels, including the HTN27K, HTN28K, HHN31V, and HHN34TVD. This shaft is a direct OEM replacement sourced from Multiquip, ensuring it meets the exact dimensional and material specifications required for proper operation in Comet-equipped drive assemblies. Keeping the correct shaft installed is critical for maintaining proper power transfer through the trowel's drive system. If you are servicing or rebuilding the drive assembly on any of the listed trowel models, part number 20043 is the correct OEM specification component.
Key Features
- Genuine OEM Dimensional Accuracy — Manufactured to the exact 1.0-inch diameter and 12.88-inch length specification required for correct bearing engagement and shaft alignment in Comet drive assemblies.
- Direct Drop-In for Comet Drive Systems — Engineered specifically for Comet-equipped trowel units; installs directly into the existing drive bearing housing without modification.
- Confirmed Fitment for HTN and HHN Series Trowels — Compatible with HTN27K, HTN28K, HHN31V, and HHN34TVD Whiteman mechanical ride-on power trowels.
- Maintains Drive System Integrity — A worn or undersized shaft causes bearing play, vibration, and accelerated wear on surrounding drive components; the correct OEM shaft restores proper load transfer and smooth operation.
- Authorized Multiquip OEM Part — Supplied through the authorized Multiquip parts network, so you receive the same component installed at the factory — not an approximation.
The drive bearing shaft transmits rotational power from the trowel's drive mechanism through the bearing assembly to the trowel arms or gearbox, depending on configuration. It must maintain precise dimensional tolerances so the surrounding bearings seat correctly and rotate without excess play or heat buildup. When a drive shaft wears, becomes scored, or falls outside specification, the result is increased vibration, bearing failure, and loss of consistent blade speed — all of which affect finish quality on the slab.
