Multiquip 12787 Spider Kit 5 Blade 1 1/4 Bore

The Multiquip 12787 Spider Kit 5 Blade 1 1/4 Bore is a genuine OEM component designed for Whiteman HTN series ride-on power trowels. This is a direct OEM replacement sourced from Multiquip, so you can be confident it meets the same specifications as the original part installed at the factory. The 12787 spider kit fits the HTN Kohler, Onan, and Honda engine variants, making it the correct choice across the HTN lineup. When you need to restore your ride-on trowel to full working order, replacing worn spider components with the genuine Multiquip 12787 is the straightforward path.

Key Features

• Genuine OEM Construction — Manufactured to the same material grade and dimensional tolerances as the original spider kit, ensuring correct blade pitch engagement and consistent rotational geometry.
• 5-Blade Configuration, 1 1/4 Bore — Designed specifically for five-blade trowel setups with a 1 1/4 inch bore, dropping directly into place on compatible HTN trowel gearboxes without modification.
• HTN Series Fitment — Confirmed fit for Whiteman HTN ride-on power trowels across Kohler, Onan, and Honda engine variants.
• Smooth Blade Operation — A properly functioning spider assembly allows each trowel blade to pivot uniformly under load, delivering a consistent, level finish across the concrete surface.
• Verified Multiquip Part Number — Sold as Multiquip 12787, matching the OEM part number used in Whiteman service documentation for accurate, mistake-free ordering.

The spider assembly is the central hub that connects and controls the pitch angle of each trowel blade on a ride-on power trowel. It translates input from the pitch-adjustment mechanism into synchronized blade movement, allowing the operator to dial in the correct finishing angle as concrete progresses from initial float to final troweling. When the spider wears or becomes damaged, blades can lose uniform pitch, resulting in uneven surface texture, increased vibration, and reduced finishing quality — making timely replacement essential to producing acceptable flatwork.
