Multiquip 11431 Thrust Collar With Bushing Heavy Rider

The Multiquip 11431 Thrust Collar With Bushing Heavy Rider is a genuine OEM component designed for HTX44, HHN, and HTN series ride-on power trowels. As a direct OEM replacement, part 11431 is manufactured to the same specifications as the original, ensuring proper fit and function within the blade pitch assembly. This part is confirmed to fit a wide range of Whiteman and international ride-on trowel models including HTX44K4, HTX44K5, HTX44Y4, HTX44Y5, HHN34TVD, HHN31V, HTN28K, HTN27K, HTNS5S-2, HHNG5, HHXD5, HHXDF4-DF5, HHXG5, HHXD5-ES, and EHHNK5.

Key Features

• Genuine OEM Durability — Manufactured to original equipment tolerances, this thrust collar and bushing assembly maintains the correct load-bearing and rotational performance that heavy-duty ride-on trowel operation demands.
• Drop-In Replacement — Engineered to match the original mounting configuration, part 11431 installs directly into the blade pitch mechanism without modification to existing hardware.
• Broad Trowel Family Fitment — Fits HTX44, HHN, and HTN series models, covering both hydrostatic and mechanical Whiteman ride-on power trowels across multiple engine configurations.
• Blade Pitch Control Integrity — A worn or failed thrust collar allows excessive play in the pitch assembly, causing uneven blade angle and inconsistent finishing results across the trowel pan.
• Heavy Rider Specification — Built to the heavy rider rating for demanding production finishing applications where the trowel is run at high blade speed and pitch under load.

The thrust collar with bushing is a critical component in the blade pitch assembly of a ride-on power trowel. It controls axial movement and reduces friction as the pitch spider adjusts blade angle during operation, allowing the operator to dial in the correct finishing pressure across the full sweep of the blades. When this component wears, excessive play develops in the pitch mechanism, leading to blade chatter, uneven float or finish passes, and accelerated wear on surrounding components.
