Multiquip 12252 Spider Assembly 4 Blade L.S. Jto/Jtn

The Multiquip 12252 Spider Assembly 4 Blade L.S. Jto/Jtn is a genuine OEM component designed for JTO-SERIES walk-behind power trowels. As a direct Multiquip OEM replacement, part 12252 is manufactured to the same specifications as the original, ensuring proper blade engagement and balanced rotor operation. This assembly is the correct replacement for JTO and JTN series machines and installs in place of the original without modification to the trowel head. Sourced directly through authorized Multiquip distribution, DHS Equipment stocks this part to keep your finishing equipment running at full capacity.

Key Features

• Genuine OEM Construction — Manufactured to Multiquip's original design tolerances, ensuring correct blade-to-spider geometry and consistent pitch transfer across all four blades.
• Direct-Fit Replacement — Engineered to drop into JTO and JTN series trowel heads, aligning with existing hardware and blade pitch hardware without rework.
• JTO-SERIES Compatibility — Confirmed fitment for Multiquip JTO-SERIES walk-behind power trowels, including JTN variants, so you can order with confidence.
• Balanced 4-Blade Rotor Performance — A correctly functioning spider assembly maintains even blade loading across the trowel head, producing a smooth, consistent finish on flatwork concrete.
• Wear-Critical Component — Spider assemblies are subject to continuous rotational stress and blade articulation loads; replacing a worn or cracked spider restores full pitch control and prevents uneven finishing or blade flutter.

The spider assembly is the central hub of a walk-behind power trowel's rotor head. It connects the gearbox output shaft to the individual trowel blades, transmitting rotational drive while also allowing each blade's pitch angle to be adjusted for floating or finishing passes. When the spider assembly wears or cracks, blades may not respond uniformly to pitch changes, resulting in an uneven surface finish, increased vibration, or complete loss of blade control. Keeping this component in good condition is essential to producing flat, burnished concrete surfaces efficiently.
