Multiquip 2845 Miter Box Horizontal Shaft - OEM Replacement Part for Walk-Behind Trowels

The horizontal shaft is a critical rotating component in the miter box assembly of walk-behind power trowels, transmitting rotational force from the gearbox to the spider assembly that drives the trowel arms. This precision-machined shaft must maintain exact tolerances to ensure smooth operation and proper blade pitch control during concrete finishing operations.

In trowel maintenance procedures, the miter box horizontal shaft works in conjunction with the spider assembly and universal stabilizer components to distribute power evenly across multiple trowel arms. Proper shaft alignment is essential for maintaining the flatness tolerances specified in Multiquip service manuals—typically within 0.004 inches (0.10mm) on hex sections and 0.005 inches (0.127mm) on round shaft sections. A worn or damaged horizontal shaft can cause uneven blade rotation, excessive vibration, and premature wear on spider bushings and trowel arm components.

Compatible with the following Multiquip trowel models:

• BHN
• HHN-34TVD
• HTN27KTCSL
