Multiquip 20938 Thrust Assembly Service for HHN Trowels - OEM Replacement Part

The thrust assembly is a critical component in ride-on power trowel operation, managing vertical load and rotational forces transmitted through the spider assembly to the blade system. This service assembly maintains proper blade pitch control and ensures smooth operation of the rotor system during concrete floating and finishing operations.

In trowels like the EHHNK5, the thrust assembly works in conjunction with the spider assembly that holds five blades in a radial pattern attached to the vertical rotating shaft. Proper maintenance of the thrust assembly is essential for maintaining the Twin Pitch Control™ system performance and preventing uneven concrete finishes. During routine maintenance, inspect for wear, concrete buildup, and proper clearances to ensure optimal trowel performance and blade stability.

This thrust assembly is designed specifically for HHN-series ride-on power trowels and is compatible with the following models:

• EHHNK5
• HHNG4
• HHXD5
• HHXDF4
• HHXG5
• HTN27KTCSL
• HTX-44K4
