The Multiquip 12766 HD Gearbox Cover 1-1/4 Shaft is a genuine OEM component designed for HTN27K, HTN28K, and HTNS5S-2 ride-on power trowel models. As a direct Multiquip OEM part, 12766 is manufactured to the same specifications as the original component it replaces, ensuring correct fitment without modification. This cover is a precision-matched replacement for contractors who depend on their finishing equipment to perform consistently through demanding concrete work.
Key Features
- Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring the cover seats correctly against the gearbox housing and maintains a secure, leak-free interface with the 1-1/4 shaft.
- Direct-Fit Replacement — Engineered to drop in as an exact replacement for the original 12766 cover, using the same mounting points and hardware configuration as the production part.
- Confirmed Trowel Fitment — Verified for use on HTN27K, HTN28K, and HTNS5S-2 Whiteman and international series ride-on power trowels.
- Gearbox Protection — Keeps gearbox internals sealed from concrete slurry, debris, and moisture that can accelerate wear on gears and bearings during finishing operations.
- Backed by OEM Part Numbering — Ordering by Multiquip part number 12766 ensures you receive the correct cover for your specific shaft diameter, eliminating guesswork when sourcing a replacement.
The HD gearbox cover on a ride-on power trowel protects the internal gearing that transfers engine power to the trowel blade arms. By sealing the gearbox housing around the output shaft, this cover prevents abrasive concrete slurry and environmental debris from contaminating the gear oil and wearing down internal components. A cracked, missing, or improperly seated cover allows contaminants to enter the gearbox, leading to accelerated gear wear, oil leaks, and eventual gearbox failure — making timely replacement critical to keeping the trowel operating at full output.
